State

Function

 

 

 

In use

Green

An NSM is installed, is receiving power, and is operational.

 

 

The NSM and its PICs are not ready for hot swap.

 

 

 

 

Off

No NSM is installed, or the NSM is not installed correctly

 

 

(the switch or router has not recognised the NSM).

 

 

 

Swap

Green

The NSM and its PICs are ready to be hot swapped.

 

 

 

 

Off

The Hot Swap button must be pressed before the NSM or

 

 

its PICs can be hot swapped, or the software release does

 

 

not support hot swapping. Hot swapping is supported by

 

 

software version 2.3.1 or later.
