Perform the following steps:
1. Turn off the battery for the new cache module by pressing
the battery’s shut off button for five seconds
2. Connect the battery to the new cache module.
3. Insert the new cache module in slot A [or B] within 4
minutes.
Note A countdown timer allows a total of four minutes to install the
cache module and controller. If you exceed four minutes, “this
controller” will exit FRUTIL and resume operations.
Caution ESD can easily damage a controller or a cache module. Wear
a snug-fitting, grounded ESD wrist strap.
7. 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 or 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.
8. Connect the ECB cable to the new cache module.
