3 Maintain the ATCA Subrack
3.6 Rear RITs
This section covers the replacement of the following ATCA Subrack Rear RITs:
JAXPC: Personality Card
JAXSSW: Rear Transition Module
JAXSMM : Shelf Management Controller
JBXPS: Power Entry Modules
A large number of cables run at the rear of the BSC. While working on a RIT,
ensure you do not accidentally disconnect cables from other RITs.
3.6.1 Replace JAXPC
Help: The two JAXPC boards slots, located on the right side of the JAXSMMs,
are numbered from 1 on the right to 2 on the left, on the back side of each
side of the subrack chassis.
The SBL number for the JAXPC1 (from the right side - logical slot 49) is 2,
while the SBL number of the JAXPC2 (from the left side - logical slot 50) is 3,
therefore the alarms for the unplugged boards will be displayed at BSC terminal
for the BSC-ENV SBL with number 2 or 3.
The following figure shows the front view for JAXPC board.
