Circuit Pack Installation
Description
This section provides the recommended order for circuit pack installation.
Locations of circuit pack units are shown in Figure 4-1 for Release 6, Figure 4-2
for Release 7, Figure 4-3 for Release 8, Figure 4-4 for Releases 9 and 11 and
either Figure 4-4, 4-5 or 4-6 for Release 13.
Circuit packs are keyed to prevent being inserted into the wrong shelf position.
Installing circuit packs requires some force. When installing the circuit packs, be
careful to insert them straight to avoid damaging the LEDs.
When a circuit pack is installed, its FAULT LED will light for several seconds then
extinguish.
NOTE
:
A wrist strap MUST be worn when handling circuit packs.
NOTE
:
The UPD/INIT pushbutton on the SYSCTL circuit pack is recessed and will
require a pointed object, like a ballpoint pen, to press it.
NOTE
:
The instructions for circuit packs not provided should be ignored.
Procedure
1. The BBG7 or BBG9/BBG10 (OHCTL) circuit pack should already be in
place from the previous software download procedure.
2. Remove the BBG5 or BBG8 (SYSCTL) circuit pack and reinsert it into the
shelf.
3. When the user panel CR LED flashes, depress the UPD/INIT pushbutton
on the front of the SYSCTL within 10 seconds. The CR LED will extinguish.
Then the appropriate ALARM LEDs will light to indicate the shelf’s present
status.
