EXB - Replacement Procedure for CPU Dual Configuration
[Start]
Replacement procedure explained here assumes the following scenario as an example:
•
EXB card (#1) must be replaced
•
EXB card (#1) is operating as ACT
Therefore, in the following explanation, replace #1 with #0 as needed when performing this procedure on the
actual system.
Note:
When this system is CPU-dual configuration, system shutdown is not necessary for EXB replacement.
STEP 1
Make sure the EXB card to be replaced is placed in STBY mode. ACT/STBY can be identified
by “ACT” lamp on the EXB card.
•
“ACT” lamp is steady ON (green): this EXB card is in ACT mode.
•
“ACT” lamp flashes (green): this EXB card is in STBY mode.
STEP 2
If the EXB to be replaced is in ACT mode, switch over CPU ACT/STBY.
•
Use CMOD command from PCPro to switch over CPU ACT/STBY.
Note:
When CPU is provided in dual configuration, ACT/STBY of EXB card and CPU always switches over in
combination.
Note:
MODE switch - 4 is Make Busy Request (MBR) key.
STEP 3
Disconnect the bus cable from the EXB card that is placed in STBY mode.

1-IMG: D37 SC50 CA-A (PIR connector)
•
4-IMG: D37 SC50 CA-B (TSWR connector)
STEP 4
Loosen the screws on the EXB card.
STEP 5
Remove the cable support bracket.
STEP 6
Pull the EXB card slowly toward you.
