Module Removal and Replacement

Module Removal and Replacement
You can remove and replace a module with the
power on. To remove and replace a module, follow
the steps in this section.
To remove a module:
Read and follow all "Safety Precautions" earlier in this
1
appendix.
Record the connections so that you can reconnect
2
them to the new module. Then disconnect all cables
attached to the module.
Loosen the captive screws that secure the module in
3
the chassis.
Move the injector/ejector handles to the outward
4
(eject) position.
Gently slide the module from the chassis.
5
To replace a module:
Read and follow all "Safety Precautions" earlier in this
1
appendix.
Ensure that you are properly grounded.
2
Insert the module in the chassis guides.
3
Gently slide the module into the chassis until it
4
touches the backplane.
Move the injector/ejector handles to the inward
5
(inject) position. You feel a slight resistance as the
module connectors and backplane connectors
engage.
