Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
CAUTION: The device ports must quiesce before removing the cache
module. Failure to allow the ports to quiesce may result in data loss.
Quiescing may take several minutes.
ESD can easily damage the cache module or a DIMM. Wear a snug-
fitting, grounded ESD wrist strap.
NOTE: A countdown timer allows a total of two minutes to remove the cache
module. If you exceed two minutes, “this controller” will exit FRUTIL and resume
operations. If this happens, return to step 3.
8. Disengage both retaining levers and partially remove the “other controller’s”
cache module—about half way.
9. Disable the ECB by pressing the battery disable switch until the status light stops
blinking—about five seconds.
CAUTION: The ECB must be disabled—the status light is not lit and is
not blinking—before disconnecting the ECB cable from the cache
module. Failure to disable the ECB could result in cache module
damage.
10. Disconnect the ECB cable from the “other controller’s” cache module, remove
the cache module, and place it onto a grounded antistatic mat or into an antistatic
bag.
Once the cache module is removed, FRUTIL displays the following:
Restarting all device ports. Please wait...
Device Port 1 restarted.
Device Port 2 restarted.
Device Port 3 restarted.
Device Port 4 restarted.
Device Port 5 restarted.
Device Port 6 restarted.
Do you have a replacement cache module? Y/N
