Replacing the External Cache Battery Storage Building Block With Cabinet
Powered On
Use the following steps to replace the ECB SSB with the cabinet
powered on:
Note The procedure for a dual-redundant controller configuration
assumes that a single ECB SBB with a dual battery is installed and an
empty slot is available for the replacement ECB SBB. If an empty slot
is not available, place the new ECB SBB on the top of the enclosure.
After the old ECB SBB has been removed, carefully insert the new
ECB SBB into the empty slot.
1. Connect a PC or terminal to the controller with the ECB SBB that you
intend to replace. The controller to which you’re connected is “this
controller.”
2. Start FRUTIL with the following command:
RUN FRUTIL
FRUTIL displays the following:
Do you intend to replace this controller’s cache battery? Y/N
3. Enter Y(es). FRUTIL displays the following:
If the batteries were replaced while the cabinet was powered
down, press return.
Otherwise follow this procedure:
WARNING: Ensure that at least one battery is connected to the
Y cable at all times during this procedure.
1. Connect the new battery to the unused end of the 'Y' cable
attached to cache A [or B].
2. Disconnect the old battery. Do not wait for the new
battery's status light to turn solid green.
3. Press return.
Caution The ECB cable has a 12-volt and a 5-volt pin. Improper
handling or misalignment when connecting or disconnecting could
cause these pins to contact ground, resulting in cache module damage.
4. Insert the new ECB SBB into the empty battery slot.
Note If an empty slot is not available, place the new ECB SBB on the
top of the enclosure.
