connectors by pushing more firmly, but do not force the module if it does not move further (excessive force can
damage the connectors).
If you are not able to push the module all the way into the slot, carefully slide the module out of the slot and
check its electrical connectors for damage. If damaged, contact Cisco Technical Assistance for help. If
undamaged, repeat this step to reinstall the module.

If the STS LED does not turn on, slide the module out of the chassis, and visually check the electrical connectors on
the back side of the chassis for damage. If damaged, contact Cisco Technical Assistance for help. If undamaged,
repeat the previous step to reinstall the module.

Replacing a Power Supply Module
The switch requires only one power supply for operations but a second one can be installed for redundancy.
With one power supply providing the necessary power for operations, you can replace the other power supply
during operations. If the switch has only one power supply, you can install and power up the replacement
power supply in the open power-supply slot before removing the original power supply.
