Installing the Modules

LED Behavior

LED Display for a Properly Installed Module

Module Status

(for the slot in which you are installing the module) The LED goes

ON as soon as the module is installed and the switch is powered on,

and stays ON steadily.

Test ON briefly while the module is being tested, then OFF.

Note: If the switch was powered off while the module was installed,

when the switch is powered on, the Test LED will stay ON for the

duration of the whole switch self test.

Fault OFF

Link and Mode (on

the modules)

For a module that is installed when the switch is already powered

on (hot swap), all the Link and Mode LEDs on the module go ON for

approximately 3 to 10 seconds, then OFF for 5 to 10 seconds

depending on the module. Then, the Test LED on the switch goes OFF.

If the module is already installed when the switch is powered on or

reset, the process described above occurs approximately 30

seconds after the power on or reset, during which the switch is

being tested.

Error Condition

If the Link LED on the module is flashing orange and the Fault LED on the

switch is on, then there is a fault condition on the port with the flashing orange

LED. The module letter, on the Management Module or System Support

Module, corresponding to the module with the flashing orange LED will also

be flashing simultaneously.
