DGS-1250 Series Gigabit Ethernet Smart Managed Switch Hardware Installation Guide 1. Introduction Switch Description Package Contents Features Front Panel Components Rear Panel Components Side Panel Components 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).
