D-Link DMS-108P 8-Port 2.5GbE PoE++ Switch – 230W PoE Budget, 90W per Port & Fanless

The D-Link DMS-108P is a compact 8-port unmanaged Multi-Gigabit PoE switch designed for high-performance home, office, surveillance and wireless networking. All eight RJ45 ports support Ethernet speeds up to 2.5Gbps and can also deliver Power over Ethernet using IEEE 802.3af, 802.3at and 802.3bt PoE++.

With a substantial 230W total PoE power budget and support for up to 90W on an individual PoE port, the DMS-108P can power demanding network devices such as Wi-Fi access points, PTZ IP cameras, VoIP equipment, kiosks, smart lighting and other compatible powered devices directly through the Ethernet cable.

The switch provides a 40Gbps switching capacity and maximum packet-forwarding rate of 29.76 million packets per second, helping multiple 2.5GbE devices communicate simultaneously without a traditional 1GbE switch becoming the bottleneck.

Its unmanaged plug-and-play design means there is no complex switch configuration required. Features including IGMP Snooping, IEEE 802.1p Quality of Service, IEEE 802.3x Flow Control, automatic speed negotiation, Auto MDI/MDIX and Energy-Efficient Ethernet operate automatically to optimise connectivity and network efficiency.

Quick answer: The D-Link DMS-108P/B is an 8-port unmanaged 2.5GbE PoE++ switch. Every port supports 10/100/1000/2500Mbps Ethernet and IEEE 802.3af/at/bt PoE, with up to 90W available on an individual port and a 230W total PoE budget. It provides 40Gbps switching capacity, 29.76Mpps forwarding, IGMP Snooping, QoS, a fanless metal chassis and simple plug-and-play installation.

Eight 2.5 Gigabit Ethernet Ports

The DMS-108P provides eight Multi-Gigabit RJ45 Ethernet ports.

Each port automatically supports:

• 10Mbps Ethernet
• 100Mbps Fast Ethernet
• 1Gbps Gigabit Ethernet
• 2.5Gbps / 2.5GBASE-T Ethernet

This allows older Gigabit devices and newer 2.5GbE equipment to be connected to the same switch.

2.5× the Bandwidth of Gigabit Ethernet

A 2.5GbE connection provides a theoretical link rate of up to:

2.5Gbps

compared with 1Gbps on standard Gigabit Ethernet.

This makes 2.5GbE particularly useful for:

• Wi-Fi 6 access points
• High-speed network storage
• NAS systems
• Workstations
• Gaming PCs
• High-resolution surveillance systems
• Large file transfers
• Media production
• 4K / 8K video workflows

Every Port Supports 2.5GbE

The DMS-108P does not reserve 2.5Gbps performance for only one or two uplink ports.

All eight RJ45 interfaces support 2.5GBASE-T operation.

This means a network can connect multiple Multi-Gigabit devices without forcing most of them back to a 1Gbps switch port.

No Dedicated Uplink Port Required

The switch does not require a special dedicated copper uplink.

Any appropriate RJ45 port can be connected to a router, gateway, another switch or network infrastructure device.

If one of the eight ports is used as an uplink, seven physical RJ45 ports remain available for other devices.

40Gbps Switching Capacity

D-Link specifies a total switching capacity of:

40Gbps

This figure represents the switch's aggregate switching fabric capacity rather than the speed of one Ethernet port.

40Gbps Does Not Mean One Port Runs at 40Gbps

Each individual Ethernet port supports up to 2.5Gbps.

The 40Gbps figure reflects the aggregate full-duplex switching capacity:

8 ports × 2.5Gbps × 2 directions = 40Gbps

This distinction is important because describing a single connection as 40Gbps would be incorrect.

29.76Mpps Packet Forwarding

The DMS-108P supports a maximum forwarding rate of:

29.76 million packets per second / Mpps

This helps the switch process large volumes of network traffic across multiple active ports.

Power over Ethernet on All Eight Ports

Every network port on the DMS-108P is PoE capable.

D-Link specifies:

PoE-enabled ports: Ports 1–8

This means compatible network devices can receive both data and electrical power through the same Ethernet connection.

Why PoE Is Useful

Power over Ethernet can reduce installation complexity because supported devices do not require a separate mains power adapter at their installation location.

This is particularly useful for equipment mounted:

• On ceilings
• High on walls
• In corridors
• Outside convenient socket locations
• In security-camera positions
• In network installations with centralised backup power

IEEE 802.3af PoE Support

The DMS-108P supports the established IEEE 802.3af PoE standard.

This allows it to power many lower-power compatible network devices such as:

• VoIP phones
• Basic wireless access points
• IP cameras
• Network sensors

IEEE 802.3at PoE+ Support

The switch also supports IEEE 802.3at PoE+, providing compatibility with devices that require more power than standard 802.3af equipment.

Typical PoE+ devices can include:

• Higher-performance wireless access points
• Advanced IP cameras
• Video phones
• Network terminals

IEEE 802.3bt PoE++ Support

For demanding powered devices, the DMS-108P additionally supports:

IEEE 802.3bt PoE++

D-Link specifies that an individual port can provide up to:

90W maximum

to an appropriately compatible powered device, subject to the switch's overall 230W power budget.

Useful for High-Power Network Devices

D-Link identifies applications including:

• High-performance Wi-Fi access points
• PTZ surveillance cameras
• Kiosks
• Smart LED lighting
• Other compatible high-power PoE devices

230W Total PoE Power Budget

The DMS-108P has a total available PoE power budget of:

230W

This is the combined amount of PoE power available across the eight PoE-enabled ports.

90W per Port Does Not Mean 720W Total

Although an individual port can support up to 90W, the total switch budget remains 230W.

It therefore cannot simultaneously provide 90W to all eight ports.

For example, the combined PoE requirements of all connected devices must remain within the available 230W total power budget.

Example PoE Deployment

A possible installation could combine devices such as:

• Several Wi-Fi access points
• Multiple PoE security cameras
• VoIP phones
• One higher-power PTZ camera

provided the total negotiated PoE requirement remains within 230W.

Automatic PoE Compatibility

Because the DMS-108P supports IEEE-standard PoE, compatible powered devices negotiate their supported power requirements with the switch.

This allows a mixture of:

• 802.3af devices
• 802.3at devices
• 802.3bt devices

to share the same switch, subject to the total PoE power budget.

Ideal for Wi-Fi 6 Access Points

D-Link specifically positions the DMS-108P as an effective Multi-Gigabit backhaul switch for Wi-Fi 6.

Modern wireless access points can deliver aggregate wireless throughput greater than 1Gbps, meaning a traditional Gigabit Ethernet uplink can become a wired bottleneck.

A 2.5GbE connection can provide additional wired backhaul capacity while PoE simultaneously powers the access point.

One Cable for Data and Power

For a compatible PoE access point, a single Ethernet cable can carry:

• Network data
• PoE electrical power

This can simplify ceiling or wall-mounted access-point deployment.

Ideal for Multi-Gigabit Surveillance Networks

The DMS-108P can also suit IP surveillance installations requiring a combination of PoE and higher network bandwidth.

Possible connected devices include:

• Fixed IP cameras
• PTZ cameras
• High-resolution cameras
• PoE NVR-related network equipment

D-Link specifically highlights HD surveillance as one of the applications for the switch.

High PoE Budget for PTZ Cameras

PTZ cameras can require more power than basic fixed cameras because they may include:

• Pan motors
• Tilt motors
• Optical zoom mechanisms
• Infrared illumination
• Heaters
• Other environmental features

The switch's 802.3bt capability can therefore be valuable for compatible high-power surveillance equipment.

Ideal for NAS and High-Speed File Transfers

The 2.5GbE ports can also improve local file-transfer performance when connected to suitable:

• NAS systems
• Servers
• Desktop PCs
• Workstations
• 2.5GbE USB adapters

A 2.5GbE connection can provide significantly more network bandwidth than Gigabit Ethernet, provided both devices and the storage system can sustain the required throughput.

Plug-and-Play Unmanaged Switch

The DMS-108P is an unmanaged Ethernet switch.

This means it is designed to work without requiring complicated switch configuration.

Simple Setup

Typical installation consists of:

• Connecting the supplied power system
• Connecting the router or upstream network
• Connecting Ethernet devices
• Allowing each port to negotiate speed automatically

No routine managed-switch configuration is required for basic operation.

What Does Unmanaged Mean?

An unmanaged switch is intended for users who want straightforward network expansion without needing advanced administrator-controlled switch configuration.

The DMS-108P still incorporates automatic networking features such as:

• QoS
• IGMP Snooping
• Flow Control
• Auto-negotiation
• Automatic MAC learning
• Energy-Efficient Ethernet

but they operate without requiring the user to configure a complex management interface.

When to Choose a Managed Switch Instead

A managed or smart-managed switch may be more appropriate if your network specifically requires administrator-controlled features such as:

• Advanced VLAN configuration
• Per-port configuration
• Detailed traffic monitoring
• Advanced access control
• Managed link aggregation
• Centralised switch-management features

IGMP Snooping

The DMS-108P includes IGMP Snooping to help optimise multicast network traffic.

Without multicast optimisation, some multicast streams can be forwarded unnecessarily to ports that do not require them.

Useful for Multicast Applications

IGMP Snooping can help improve efficiency for services such as:

• IPTV
• Multicast video
• Surveillance streams
• Other multicast applications

D-Link states that IGMP Snooping intelligently directs multicast traffic to the devices that need it, helping reduce unnecessary network flooding.

IGMP Snooping Is Not an IP Routing Protocol

The DMS-108P is a Layer-2 unmanaged switch.

IGMP Snooping is a multicast traffic-optimisation feature and should not be described as IP routing capability.

IEEE 802.1p Quality of Service

The switch supports IEEE 802.1p QoS.

D-Link's datasheet states that traffic can be classified into:

8 priority levels

helping higher-priority or time-sensitive traffic receive appropriate treatment.

Useful for Voice and Video Traffic

QoS can be beneficial for network applications such as:

• VoIP calls
• Video conferencing
• Video streaming
• IPTV
• Other latency-sensitive traffic

IEEE 802.3x Flow Control

The DMS-108P supports IEEE 802.3x Flow Control.

When a receiving buffer becomes full, flow control can temporarily pause transmission to help reduce dropped packets and maintain a more reliable connection.

1MB Packet Buffer

D-Link specifies a packet buffer of:

1MB

The buffer temporarily stores Ethernet frames during periods of traffic congestion or when data arrives faster than an outgoing link can immediately transmit it.

4K MAC Address Table

The switch supports a MAC address table containing up to:

4,000 entries

MAC addresses are learned automatically so the switch can direct Ethernet traffic to the correct physical port.

Automatic MAC Address Learning

The DMS-108P automatically learns connected device MAC addresses and updates its forwarding table without manual configuration.

Store-and-Forward Switching

D-Link specifies a store-and-forward transmission method.

This conventional Ethernet switching method receives a complete frame before forwarding it to the destination port.

Auto MDI/MDIX on Every Port

Every port supports automatic MDI/MDIX crossover detection.

This means users do not normally need to choose between straight-through and crossover Ethernet cables when connecting:

• Computers
• Routers
• Switches
• Servers
• Access points
• Other Ethernet devices

Automatic Link Speed Negotiation

Each port automatically detects the connection speed supported by the attached network device.

A mixture of:

• 10Mbps
• 100Mbps
• 1Gbps
• 2.5Gbps

devices can therefore be connected at the same time.

Upgrade from Gigabit Without Moving to 10GbE

2.5GBASE-T provides a useful middle ground between standard Gigabit Ethernet and more expensive 10GbE infrastructure.

D-Link specifically highlights that Multi-Gigabit Ethernet can help increase network speed without necessarily replacing existing compatible copper infrastructure.

Existing Cabling May Be Reusable

In suitable installations, 2.5GBASE-T can operate over compatible existing Ethernet cabling.

Actual achievable link speed depends on:

• Cable category
• Cable quality
• Run length
• Termination quality
• Network adapter capability
• Environmental interference

Fanless Silent Operation

The DMS-108P uses a fanless cooling design.

This means there is no internal cooling fan generating continuous mechanical noise.

Ideal for Noise-Sensitive Locations

Fanless operation can make the switch suitable for:

• Home offices
• Small offices
• Desks
• Meeting rooms
• Studios
• Quiet workspaces
• Living areas

No Cooling Fan to Wear Out

Removing a mechanical fan also eliminates one moving component from the switch, which can help simplify long-term operation and maintenance.

Durable Metal Housing

D-Link uses a metal enclosure rather than a lightweight plastic shell.

The metal chassis helps provide:

• Physical durability
• Passive heat dissipation
• Protection for the networking electronics
• A compact professional desktop design

Energy-Efficient Ethernet

The DMS-108P supports IEEE 802.3az Energy-Efficient Ethernet / EEE.

D-Link states that this technology reduces switch power consumption when network utilisation is low.

Link Status Detection

D-Link Green technology can also detect when an Ethernet link is inactive.

When a connected device is shut down or disconnected, the switch can reduce power use on the inactive network connection.

External Power Supply

Because of the high 230W PoE budget, the DMS-108P uses an external power supply.

D-Link specifies the switch power input as:

54V / 4.62A

Maximum Power Consumption

D-Link's official datasheet lists maximum total power consumption of:

261.02W

This figure represents maximum switch power consumption under the manufacturer's specified operating conditions and should not be confused with the 230W PoE output budget.

230W PoE Budget vs 261.02W Input Consumption

The figures describe different things:

• 230W: maximum total PoE power budget available to powered devices
• 261.02W: D-Link's listed maximum total switch power consumption

Compact Desktop Dimensions

Despite the high PoE budget, the DMS-108P has a compact desktop enclosure measuring:

• Width: 190mm
• Depth: 120mm
• Height: 38mm

Overall dimensions:

190 × 120 × 38mm

753g Metal Chassis

D-Link specifies a switch weight of approximately:

0.753kg / 753g

Front Status LEDs

The switch includes status indicators for:

• System power
• Link / activity per Ethernet port
• PoE status per port

These indicators make it easier to check basic network and power status without connecting to a management interface.

Operating Temperature

D-Link specifies an operating temperature range of:

0°C to 40°C

Storage Temperature

The specified storage temperature range is:

-10°C to 70°C

Operating Humidity

The switch is specified for:

• Operating humidity: 10% to 90% RH
• Storage humidity: 5% to 90% RH

Designed for SOHO Networks

D-Link specifically positions the DMS-108P for Small Office / Home Office / SOHO networking.

It can be particularly useful where a network needs both:

• Multi-Gigabit performance
• A substantial PoE power budget

without requiring a fully managed enterprise switch.

Suitable for Small Business Networks

Potential small-business installations include:

• Offices
• Retail premises
• Studios
• Small warehouses
• Training rooms
• Professional home offices
• Surveillance installations

Suitable for High-Speed Home Networks

Home users can also use the DMS-108P to connect a mixture of:

• Gaming PCs
• NAS devices
• 2.5GbE computers
• Wireless access points
• PoE cameras
• Media systems

The fanless design is especially useful where the switch will be located inside a home office or living environment.

DMS-108P vs DMS-108

The model name is similar to D-Link's DMS-108, but the two products are not identical.

DMS-108P

• 8 × 2.5GbE ports
• PoE on all eight ports
• 802.3af / at / bt
• Up to 90W per PoE port
• 230W total PoE budget
• 40Gbps switching capacity
• Fanless

DMS-108

• 8 × 2.5GbE ports
• No integrated PoE power delivery
• 40Gbps switching capacity
• Fanless

If powered network devices are required, the DMS-108P is the appropriate PoE-equipped version.

Does the DMS-108P Have 10GbE Ports?

No.

The highest Ethernet link rate supported by each RJ45 port is:

2.5Gbps

The 40Gbps switching-capacity figure should not be confused with a 10GbE or 40GbE physical port.

Does the DMS-108P Have SFP or SFP+?

D-Link's official interface specification lists:

8 × copper 10/100/1000/2.5G PoE Ethernet ports.

No separate SFP or SFP+ fibre interface is listed for the DMS-108P.

Does the DMS-108P Need Configuration?

No complex setup is required for normal switching operation.

It is an unmanaged plug-and-play switch, so users can connect compatible devices and allow the switch to negotiate their Ethernet speeds automatically.

Can All Eight Ports Supply PoE?

Yes.

D-Link specifically lists:

PoE-enabled ports: 1 to 8.

All eight physical network connections can therefore power compatible IEEE PoE devices.

Can Every Port Supply 90W at the Same Time?

No.

The maximum on one compatible port is 90W, but the total PoE budget across the switch is 230W.

The total power requirements of all connected PoE devices must stay within that budget.

Can It Power PoE, PoE+ and PoE++ Devices?

Yes, where the powered device follows the supported IEEE standards.

The DMS-108P supports:

• IEEE 802.3af PoE
• IEEE 802.3at PoE+
• IEEE 802.3bt PoE++

Important 40Gbps Switching Capacity Note

The DMS-108P has a 40Gbps aggregate switching capacity.

This does not mean an individual port operates at 40Gbps.

Each physical Ethernet port supports a maximum negotiated link speed of 2.5Gbps.

Important PoE Budget Note

The switch supports up to 90W on an individual IEEE 802.3bt-compatible port, but the maximum combined PoE budget is 230W.

Always calculate the power requirements of all connected PoE devices before installation.

Important PoE Device Compatibility Note

A powered network device should support an appropriate IEEE PoE standard:

• 802.3af
• 802.3at
• 802.3bt

Do not assume that proprietary or non-standard passive PoE equipment is compatible simply because it uses an Ethernet connector.

Important 2.5GbE Performance Note

To achieve a 2.5Gbps Ethernet link, both ends of the connection must support 2.5GbE.

If a connected device supports only 1GbE, the switch automatically negotiates the lower supported link speed.

Important Cable Note

Actual 2.5GbE link performance depends on the quality, category, length and installation condition of the Ethernet cabling.

The switch cannot correct faults caused by damaged, poorly terminated or unsuitable network cabling.

Important Unmanaged Switch Note

The DMS-108P is designed for straightforward plug-and-play networking.

Users requiring advanced administrator-controlled switching features should consider a suitable smart-managed or managed D-Link switch instead.

Important IGMP Note

IGMP Snooping is included to optimise multicast traffic.

It should not be interpreted as Layer-3 IP routing functionality.

Important Fanless Operation Note

The DMS-108P contains no active cooling fan.

Ensure adequate ventilation around the metal enclosure and avoid blocking its ventilation openings, particularly when the switch is providing substantial PoE power.

Important Power Consumption Note

D-Link lists:

• PoE power budget: 230W
• Maximum system power consumption: 261.02W

These values are not interchangeable.

Important Product Identification Note

The UK retail version on this page is:

• D-Link model: DMS-108P
• UK MPN: DMS-108P/B
• Memox SKU: 11889655
• UPC-12: 790069477980
• EAN / GTIN-13: 0790069477980

Do not confuse the DMS-108P/B with the non-PoE DMS-108.

Who Is the D-Link DMS-108P Best For?

• Small businesses
• Home offices
• Wi-Fi 6 access-point installations
• Multi-Gigabit wireless networks
• PoE surveillance systems
• PTZ camera installations
• NAS and high-speed storage networks
• 2.5GbE desktops and workstations
• Users upgrading from Gigabit Ethernet
• Networks needing both 2.5GbE and PoE++
• Quiet offices requiring a fanless switch
• Users wanting plug-and-play installation

Who Should Consider a Different Switch?

A different switch may be more appropriate if you specifically require:

• 10 Gigabit Ethernet ports
• SFP or SFP+ fibre uplinks
• More than eight Ethernet ports
• More than 230W total PoE capacity
• 90W simultaneously on all eight ports
• Advanced managed-switch configuration
• Detailed per-port administrator controls
• Advanced VLAN management
• Enterprise switch stacking

Why Choose the D-Link DMS-108P?

The D-Link DMS-108P combines three features that are often required together in a modern small-business network: 2.5 Gigabit Ethernet, high-power PoE++ and simple unmanaged operation.

All eight ports support 2.5GbE rather than limiting Multi-Gigabit connectivity to one uplink. This makes it possible to connect multiple access points, workstations, NAS devices, cameras and other high-speed network devices without pushing them through conventional 1Gbps ports.

Every port also supports IEEE-standard PoE, including 802.3bt PoE++ with up to 90W available on an individual compatible port. The large 230W combined power budget makes the switch suitable for more demanding PoE installations than many compact desktop switches.

A 40Gbps switching fabric and 29.76Mpps forwarding rate provide the internal capacity needed for high-bandwidth Multi-Gigabit traffic, while the 4K MAC table, 1MB packet buffer and store-and-forward architecture handle normal Ethernet switching automatically.

Built-in IGMP Snooping helps manage multicast streams, 802.1p QoS prioritises important traffic, and 802.3x Flow Control helps reduce dropped packets during congestion.

The DMS-108P is also simple to deploy. Auto-negotiation automatically selects between 10Mbps, 100Mbps, 1Gbps and 2.5Gbps, while Auto MDI/MDIX eliminates the need to select special crossover Ethernet cables.

Its fanless metal chassis provides completely silent operation, while IEEE 802.3az Energy-Efficient Ethernet and D-Link Green technology help reduce unnecessary power consumption when links are inactive or lightly used.

Choose the D-Link DMS-108P if you need eight 2.5GbE ports, PoE on every port, up to 90W PoE++ for demanding devices, a 230W total PoE budget and silent plug-and-play operation in one compact metal switch.
