Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
CAUTION: ESD can easily damage a controller or a cache module. Wear
a snug-fitting, grounded ESD wrist strap.
10. Disable the ECB to which you’re connecting the new cache module 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 connecting the ECB cable to the cache module.
Failure to disable the ECB could result in ECB damage.
Make sure you align the cache module and controller in the appropriate
guide rails. If you do not align the modules correctly, damage to the
backplane can occur.
11. Connect the ECB cable to the new cache module.
12. Insert the new cache module into its slot and engage its retaining levers. FRUTIL
displays the following:
Insert the controller module, WITH its program card, in slot A [ or B ]
within x minutes, xx seconds.
13. Ensure that the program card is in the replacement controller and insert the new
controller into its slot. Engage its retaining levers. When fully seated, the newly
installed controller will boot.
FRUTIL displays the following:
If the other controller did not restart, follow these steps:
1. Press and hold the other controller’s reset button.
2. Insert the other controller’s program card.
3. Release the reset button.
Press return to continue.
NOTE: In mirrored mode, FRUTIL will initialize the mirrored portion of the new cache
module, check for old data on the cache module, and then restart all device ports.
After the device ports have been restarted, FRUTIL will test the cache module and the
ECB. After the test completes, the device ports will quiesce and a mirror copy of the
cache module data will be created on the newly installed cache module.
