12 Remove the card cage from the module.

Note: For AC-powered systems: If the new NT5D21 Core/Network

module did not come with a module Power Distribution Unit (MPDU),

you must remove the MPDU from the CPU/Network card cage and

reinstall it on the new Core/Network card cage after the CPU/Network

card cage is out of the module. The screw-heads for the MPDU are in the

wall of the power supply slot (see Figure 9-4).

13 If a new floating power connector was not included in the upgrade kit,

remove the existing floating power connector (the black connector) from

the rear of the CPU card cage. Using the same mounting screws and nuts,

attach the connectors to the Core/Network card cage.

Note: Check the orientation of the connector. Viewed from the rear of

the card cage, the upper left corner position should be empty (no wire)

and the lower right corner position should have a wire installed. The

green wire should be up.
