The DGS-1510-28P we looked at also features Power-over-Ethernet with support for devices drawing up to 15.4 Watts (802.3af) or 30 Watts (802.3at). This can be delivered across all 24 ports although, with a power budget of just 193 Watts overall, the number of devices that can get their power this way is a little limited.

On the plus side small businesses generally only use PoE for simple wireless access points and IP phones with low power requirements. Added to which there are controls in the management interface to cap and schedule power delivery on a per-port basis, to better share out what’s available.


There are four models in the DGS-1510 SmartPro series, each equipped with four SFP ports for fibre connectivity and either 16 (DGS-1510-20), 24 (DGS-1510-28) or 48 copper UTP ports (DGS-1510-52). There’s also a PoE enabled version of the 24-port model (the DGS-1510-28P) which we were sent for testing which, although not available at the time of the review, was being marketed online for around £425 (ex. VAT).

For companies in serviced offices the smallest of the new D-Link switches could easily be used standalone but most customers will opt for rack mounting for which brackets are provided. Installation is easy and there’s nothing remarkable about the all-metal chassis design with power applied at the back and the network interfaces spread across the front panel. The usual LEDs indicate port status and activity, and there’s also a separate RJ45 connector for local console management using an adapter cable shipped in the box.

Fans are needed to keep the electronics at the right temperature in this range of switches with either one or two, dependent on model, venting to the side. Our PoE switch had two fans, resulting in a noise profile which, although not overly intrusive, we felt best suited to data centre or cabinet deployment rather than an open plan office.

Of course PoE switches are, of necessity, big energy consumers, but support for the 802.3az Energy Efficient Ethernet standard enables all the DGS-1510 switches to scale back on power when network activity is low. Added to that proprietary D-Link Green 3.0 technology allows other energy saving measures to be applied, such as shutting down unused ports and turning off unnecessary LEDs.

The UTP capabilities are generally unremarkable with the ports provided all Gigabit capable and the D-Link switch automatically adapting the setup of each to match both the speed of the attached endpoint and the type of cable. The four SFP ports, meanwhile have a dual role and can either be used to connect to servers, switches and so on or, by using optional direct-attach cables, to provide the interconnect for a physical switch stack.

Up to six switches can be stacked this way to provide up to 288 switched Gigabit ports managed as a single unit. Added to which there’s support for “virtual stacking” whereby up to 32 distributed switches can be managed together, albeit without the benefit of the high-speed interconnect.

However you choose to use the SFP ports, you do still have to buy transceivers before fibre can be attached with two of the ports limited to Gigabit while the other two (the SFP+ ports) can take either Gigabit or 10GbE transceivers.

Pricing is largely dependent on the type of fibre involved and the bandwidth required. Gigabit 1000 BASE-SX transceivers, for example, can be had for as little as £56 (ex. VAT), whereas you’ll need to spend between £200 and £360 (ex. VAT) to get 10GbE connectivity. Direct attach cables for stacking also have to be bought separately.
