Installation
1. If installing a new PCBA:
a.
Compare the original PCBA with the replacement. If the new board
is a different firmware version, refer to the P9012 User’s Manual for
configuration details.
b. If the new board is the same firmware version, remove any PROMs,
jumpers, or terminations from the original board and install them on
the replacement board. (For PROM locations, refer to page 6–73.)
CAUTION
Installing a PCBA in the wrong slot will damage the PCBA and
connector.

side on the right. Engage the ejection levers at the edge of the card cage
and close to seat the PCBA.
3. On the DCU only, connect two connectors.
