7. Connect Network Cables
For RJ-45 ports, connect 100-ohm Category 5, 5e or better
twisted-pair cable.
For the SFP/SFP+ slots, first install SFP/SFP+ transceivers and
then connect fiber optic cabling to the transceiver ports.
The following transceivers are supported:
◆
10GBASE-CR
◆
10GBASE-SR
◆
1000BASE-SX
◆
1000BASE-LX
◆
1000BASE-T
As connections are made, check the port status LEDs to be
sure the links are valid. Press the Mode button to change
from Ethernet to PoE status:
◆
On/Blinking Green — Port has a valid link. Blinking
indicates network activity.
◆
On Amber — Port is supplying PoE power.
