3–20 Upgrading the Subsystem
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 the ECB being damaged.
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.
9. Connect the ECB cable to the new cache module.
10. 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 B within
x minutes, xx seconds.
11. 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 buttons.
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.
12. Connect the trilink connectors with host bus cables (or terminators) to the new
controller.
NOTE: One or two trilink connectors with host bus cables (or terminators) may be
attached, depending on the configuration.
