1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for a 100BASE-TX connection should also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any new cable installations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e and 6 specifications include test parameters that are only
recommendations for Category 5. Therefore, the first step in preparing existing
Category 5 cabling for running 1000BASE-T is a simple test of the cable installation
to be sure that it complies with the IEEE 802.3-2008 standards.
To make a connection to the switch's management port follow the procedure
described in
"How to Connect to the Management Port" on page
The switch provides 48 slots for SFP/SFP+ fiber-optic transceivers. Note that all 10G
SFP+ fiber optic ports operate at 10 Gbps full duplex. All 1000 Mbps SFP fiber optic
ports operate at 1 Gbps full duplex.
