E. Install Circuit Packs

(1) The label on the support case cover provides

a quick reference to color coding, slot

number locations, and the direction the

T400 card MUST be installed. See Figure

8. (Circuit pack #1 and circuit pack #2

MUST be installed in the opposite direction

from circuit pack #3 and circuit pack #4,

resulting in a back-to-back placement of

circuit pack #2 and circuit pack #3.)

A Slot Location Label is placed around the

housing card-edge connectors showing the

proper orientation of the circuit packs.

Labels affixed inside the repeater housings

provide wiring connection information for

each type of repeater.

The Test Access Card, shipped with each

Housing, may be used to assist with

installing and troubleshooting T400 and

T200 circuits and removed for future use.

Refer to the Test Access Card I/M Practice

(61244065L1-5) for more details.

Refer to Table A for Repeater Housing

Capacity Specifications. Heat dissipation

from the circuit packs AND the collection

of heat from solar loading must be

considered to avoid overheating conditions

inside the Environmental Housings.

(2) Open the support case cover by pulling the

spring-loaded plunger.

(3) Remove the shipping supports from the card

guides.
