Switch Description
The DGS-1250 Series is D-Link's next generation Smart Managed Switch. The Switch has a combination of
10/100/1000 Mbps RJ45 ports and 1/10 Gbps SFP/SFP+ ports that may be used to connect various networking
devices to the Switch. The SFP/SFP+ ports are used with fiber-optical transceiver cabling in order to uplink various
other networking devices for a 1/10 Gbps link that may span great distances. The DGS-1250 Series also implements
D-Link's innovative 3rd generation Green Ethernet technology (IEEE 802.3az) by not only saving power over inactive
links, but also turning off LEDs on a customized schedule and allowing ports to automatically enter the hibernated
state.
The D-Link DGS-1250 Series includes the following switches:
• DGS-1250-28X supports twenty-four RJ45 ports (10/100/1000 Mbps) and four SFP/SFP+ ports (1/10 Gbps).
• DGS-1250-28XMP supports twenty-four RJ45 PoE ports (10/100/1000 Mbps) and four SFP/SFP+ ports (1/10
Gbps).
• DGS-1250-52X supports forty-eight RJ45 ports (10/100/1000 Mbps) and four SFP/SFP+ ports (1/10 Gbps).
• DGS-1250-52XMP supports forty-eight RJ45 PoE ports (10/100/1000 Mbps) and four SFP/SFP+ ports (1/10
Gbps).
