D-Link’s new SmartPro switches marry copious features with rock-bottom prices. The DGS-1510-28P on review sports 24 Gigabit ports, plus pairs of Gigabit and 10GbE fibre uplinks, yet costs less than £400. A remarkable feat. The switch is fully manageable, while the main 24 Gigabit ports all support PoE and high-power PoE+. The only compromise to keep the price down is a modest power budget of 193W.
The front panel offers minimal status information; there are link and activity LEDs for each port, but only a single PoE status light, which turns amber if there’s a problem. You’ll find more information on the switch’s web interface, which provides a complete overview on each port’s power usage.
One of three priorities can be applied per port to ensure that critical PoE devices keep running when you’re close to the user-defined global power threshold. The interface shows power consumption for the switch and each port, along with the class of device attached, so you can keep a close eye on this. D-Link’s Green 3 feature provides more power-saving controls: ports that aren’t in use can be turned off, and port shutdowns can be scheduled, as can a switch hibernation mode, and you can even dim the status LEDs during specific periods.
Up to 32 switches can be placed in a virtual stack and managed via a single IP address. You can also use the 10GbE ports as high-speed links to create a physical stack of up to six switches. Along with an extensive range of L2 features, the switch also offers D-Link’s proprietary Auto Surveillance and voice VLANs. These automatically identify this type of traffic, place it in the relevant VLAN and apply QoS to prioritise it.
The switch provides basic L3 routing features and a few interesting security measures. D-Link’s Safeguard Engine monitors CPU usage and protects against network attacks, while its DHCP server screening prevents unauthorised IP address assignments. D-Link’s DGS-1510-28P trumps the big names for value, with comparable HP and Cisco switches costing up to five times more. Its power budget is modest, but if you want a low-cost Gigabit PoE+ switch with high-speed 10GbE server uplinks, you should take a closer look.
