Tip
If you plan to return the defective PEM to the factory, repackage it in the shipping
container you received with the replacement PEM.

connector.

Electrical connections between the PEM the backplane connector are made
automatically when the PEM is fully seated and the captive screws are tightened.

cord to secure it in place.
