8. Enter Y(es) and press return. FRUTIL displays the following:
Quiescing all device ports. Please wait...
Device Port 1 quiesced.
Device Port 2 quiesced.
Device Port 3 quiesced.
Device Port 4 quiesced.
Device Port 5 quiesced.
Device Port 6 quiesced.
All device ports quiesced.
Remove the slot A [
or B ] controller (the one without a blinking green
LED) within 4 minutes.
CAUTION: The device ports must quiesce before removing the
controller. Failure to allow the ports to quiesce may result in data loss.
Quiescing may take several minutes.
ESD can easily damage a controller, cache module, or DIMM. Wear a
snug-fitting, grounded ESD wrist strap.
NOTE: A countdown timer allows a total of four minutes to remove both the
controller and cache module. If you exceed four minutes, “this controller” will exit
FRUTIL and resume operations. If this happens, return to step 4.
9. Remove the trilink connectors from the “other controller” but don’t disconnect
the host bus cables (or terminators) from the trilink connectors.
NOTE: One or two trilink connectors with host bus cables (or terminators) may be
attached, depending on the configuration.
10. Disengage both retaining levers and remove the “other controller,” then place the
controller into an antistatic bag or onto a grounded antistatic mat.
Once the controller is removed, FRUTIL displays the following:
Remove the slot A [ or B ] cache module within x minutes, xx seconds.
11. Disengage both retaining levers and partially remove the “other controller’s”
cache module—about half way.
