Installing the gl Modules

Verifying the Network Connections Are Working

Check the port LEDs for the newly-installed module to ensure that the port(s)

connected in the preceding step are operating correctly. Each port on the

switch modules has Link and Mode LEDs near it as shown in the next

illustration. The Link LED lights up the port number and the Mode LED lights

up the little white box next to the number.

duplex.

If the Mode is set to display maximum link speed operation (the ï

indicator LED is lit), then the Mode LED will be lit for each port that is

operating at its maximum possible link speed. For gigabit-capable ports,

that speed would be 1000 Mbps (Gigabit); for 10/100 ports, that speed

would be 100 Mbps.
