Connecting to the Network 33
b If the Link LED is unlit, check the cable and verify that the device at the
other end of the link is operating.
Connecting to Gigabit
Ethernet Devices
The following procedures explain how to connect a WX400 switch’s
copper or fiber Gigabit port to the network.
WARNING: The gigabit Ethernet fiber-optic interfaces use Class 1 lasers.
To reduce the risk of eye injury, do not stare into the interface or
otherwise direct the laser beam into your eye.
Connecting to a Copper Gigabit Device
Insert a Cat 5 cable with a standard RJ-45 connector. The cable can use
straight-through or crossover signalling.
1 Insert the Cat 5 cable into the port’s RJ-45 (copper) interface.
2 Access the command-line interface (CLI) on the switch, use the enable
command to enter configuration mode, and use the following command
to set the active interface on the port to RJ-45 (copper):
set port preference port-list rj45
3 Observe the lower LED to the left of the port:
■ If the LED is solid green, the 1000-Mbps link is operational.
■ If the LED is blinking green, traffic is active on the 1000-Mbps link.
■ If the LED is unlit, the link is not operational. Check the cable and
verify that the device at the other end of the link is operational.
Connecting to a Fiber Gigabit Device
You must install a gigabit interface converter (GBIC) to connect a
WX4400 switch to 1000BASE-SX or 1000BASE-LX cable. (For cable
requirements, see “Network Cables” on page 22.)
To install a GBIC:
1 Insert the GBIC into a GBIC slot on the front panel until it clicks into
place.
2 Remove the protective covering(s) from the port connector(s) and set
them aside in a safe place for later use.
3 Insert the network cable.
