Connecting to Network Backbone or Server
The combo SFP ports and the 1000BASE-T ports are ideal for uplinking to a network backbone, server or server farm.
The copper ports operate at a speed of 1000, 100 or 10Mbps in full or half duplex mode. The fiber-optic ports can
operate at both 100Mbps and 1000Mbps in full duplex mode.
Connections to the Gigabit Ethernet ports are made using a fiber-optic cable or Category 5e copper cable, depending
on the type of port. A valid connection is indicated when the Link LED is lit.
