Note 1: Leave the network cards in the card cage. You will relocate them
to the CP card cage later in the upgrade procedure.
Note 2: Two people are needed to remove the Core card cage because
of the weight of the card cage with the cards left installed.
7 At the bottom rear of the card cage, remove the two mounting screws that
secure the card cage to the module casting.
CAUTION
Do not drop the mounting screws into the pedestal.
Doing so can cause serious damage.
Keep the screws for use with the CP card cage. (You need a 1/4" nut
driver to remove the screws.)
8 Remove the front trim panels on both sides of the card cage.
9 Remove the three mounting screws that secure the front of the card cage
to the bottom of the module. Save the screws for use with the CP card
cage.

11 Disconnect cables, plugs, and wires from the rear of the module to the
backplane.
12 Remove the logic return (LTRN) (orange) wire from the backplane bolt.
Be careful; do not drop the nut or lock washer into the pedestal. For DC
power connectors, see Figure 19 on

13 Remove the frame ground (FGND) (green) wire from the frame ground

DC-powered system.
