Chapter 2 Preparing to Install
IGX 8420 or IGX 8430 Enclosure Installation
Step 2 To install the optional AC power supply kit, complete the steps in the “Installing the IGX 8420 or
IGX 8430 AC Power Supply Assembly” section on page 2-26.
Step 3 To install the cooling unit, complete the steps in the section titled “Installing the Cooling Unit” section
on page 2-33.
Step 4 Install the brackets for the card cages.
Step 5 Position the IGX card cage so the back of it faces the front of the cabinet.
Caution An empty card cage requires two or three people to move it.
Step 6 With one person on each side of the card cage, lift it into the rack. In a Cisco cabinet, rest the back of
the card cage on the rear-bracket flange.
When mid-mount brackets are used, screw the card cage to the brackets with #10-32 machine screws
from the miscellaneous parts kit.
Step 7 Secure the front of the card cage to the front of the rack with #10-32 machine screws from the
miscellaneous parts kit.
Caution Make sure that mounting the equipment does not create a hazardous condition because of uneven
mechanical loading. The equipment rack should be securely supported.
Step 8 The folded ribbon cables that connect the upper and lower backplanes pass through a cut-out space in
the card cages. The cables connect to two 100-pin connectors on the front of each backplane. See
Figure 2-8. If nodal processor module (NPM) cards are present, these and possibly other front cards must
be removed prior to ribbon cable installation.
Connect the cable from the upper connector of the upper backplane to the upper connector in the lower
backplane.
Connect the cable from the lower connector of the upper backplane to the lower connector in the lower
backplane.
Step 9 A two-piece conduit called the card cage tunnel surrounds the ribbon cables and sits in the cut-out space
of the card cages. Fit the pieces of the card cage tunnel around the ribbon cables and screw this unified
piece into the cut-out space. Figure 2-8 shows the card cage tunnel in its normal location and prior to
assembly.
Step 10 Slip the ribbon cables through the fastener clamps, then attach the fastener clamps (which include a
self-adhesive base) to the side of the card cage. See Figure 2-8.
Step 11 If this is an AC-powered system, complete the procedures in the “Installing the IGX 8420 or IGX 8430
AC Power Supply Assembly” section on page 2-26.
Step 12 If this is a DC-powered system, go to the “DC Power Connections” section on page 2-41.
