Chapter 2 Preparing to Install
IGX 8420 or IGX 8430 Enclosure Installation
Step 5 With one person on each side of the card cage, lift and slide it into the rack.
Step 6 Attach the cabinet to the rack with 8 #10-32 machine screws (from the kit).
Step 7 For system DC-powered systems, see the “DC Power Connections” section on page 2-41. For
AC-powered systems, see the “Installing the IGX 8420 or IGX 8430 AC Power Supply Assembly”
section on page 2-26.
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.
IGX 8430 Rack-Mount Installation
The IGX 8430 is designed for mounting in a 19-in. (48.25-cm) equipment rack. The following order of
component installation is the most convenient and efficient. For some of these components, separate
sections follow that contain detailed installation steps.
1. Optional AC power assembly
2. Lower cooling unit
3. Lower card cage
4. Upper card cage
5. Ribbon cables for connecting upper and lower backplanes
6. Card cage tunnel around backplane ribbon cables
7. Upper cooling unit (also called booster fan unit)
8. Exhaust plenum
The miscellaneous parts kit contains brackets for rack-mounting in either a Cisco cabinet or a
user-supplied rack. The kit includes mid-mount brackets for open racks. For a Cisco cabinet, the
rear-mount brackets attach to the rear vertical rail. Each of these brackets has a horizontal flange upon
which the back of an individual component rests. The front of each assembly chassis has flanges that
serve as front mounting brackets.
Caution If an IGX 8430 node goes in a user-supplied cabinet, be sure that air can freely flow in and out of the
enclosure. Note also that the vertical spacing between components, such as the card cage and fan tray,
must be in the range 0.047–0.077 in. (0.119–0.196 cm).
Caution When moving a Cisco cabinet, do not push the cabinet at its sides. Instead, grip the front or back edges.
Step 1 Refer to Figure 2-7 for component dimensions. Note that, although Figure 2-7 shows mid-mount and
rear-mount brackets, these brackets are not normally used together.
