2–20 Replacement Procedures
12. 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.
13. 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 controller and cache module? Y/N
14. Enter N(o) if you don’t have a replacement controller and cache module;
FRUTIL will exit. Disconnect the PC or terminal from the controller’s
maintenance port.
Enter Y(es) if you have a replacement controller and cache module and want to
install it now. FRUTIL displays the following:
Insert both the slot A [ or B ] controller and cache module? Y/N
NOTE: If you entered Y(es) go to step 9 on page 2–22.
Remove the DIMMs from the cache module. They will be installed in the
replacement cache module.
15. Press down on the DIMM retaining levers at either end of the DIMM you want to
remove.
