Use the following steps to replace the ECB.
1. Connect a PC or terminal to the maintenance port of the controller with the ECB
that needs replacement.
The controller connected to the PC or terminal becomes "this controller."
2. Enter the following command to verify that system time is set:
SHOW THIS_CONTROLLER FULL
If system time is not set or current, enter the current time using the following command:
SET THIS_CONTROLLER TIME=dd-mmm-yyyy:hh:mm:ss

RUN FRUTIL
4. Enter Y(es) to confirm the intent to replace the "this controller" ECB.

cache module as the current ECB being removed—ECB bay A1 and A2 are paired and
ECB bay B1 and B2 are paired.
Remove the blank bezel from this replacement bay and reinstall the blank bezel in the
bay vacated by the ECB being replaced. Failure to reinstall the blank bezel might
cause an over-temperature condition and damage the enclosure.
5. Install a Battery Service Label on the replacement ECB as described by the
Compaq StorageWorks Battery Service Label Placement installation card.
NOTE: The Battery Service Label indicates the installation date (MM/YY) for the
replacement ECB.
6. Remove the blank bezel from the appropriate bay and insert the replacement ECB.
