Installing a circuit card
This procedure provides detailed installation instructions for circuit cards.
Procedure 1
Installation
1 Open the protective carton and remove the circuit card from the antistatic
bag. Return the antistatic bag to the carton and store it for future use.
2 Inspect the card components, faceplate, locking devices, and connectors
for damage. If damaged, tag the card with a description of the problem
and package it for return to a repair center.
3 Refer to the work order to determine the module and slot location for the
card.
4 If there is an enable/disable (Enb/Dis) switch on the faceplate, set it to Dis.
5 If there are option switches or jumpers on the card, set them according to
the work order (see “Option settings” on
page 101 ).
6 Squeeze the ends of the locking devices on the card and pull the tabs
away from the latch posts and faceplate (see Figure 16).
