4. Enter Y(es) to confirm the intent to replace the “this controller” ECB with
power on.
Caution: Ensure that at least one ECB is connected to the ECB Y-cable at all
times during this procedure. Otherwise, cache memory data is not protected
and is subject to loss.
The ECB Y-cable has a 12-volt and a 5-volt pin. Improper handling or
misalignment while connecting or disconnecting can cause these pins to
contact ground, resulting in cache module damage.
Note: If you are using a BA370 subsystem and upgrading to a dual-redundant
controller configuration, if an empty power supply or disk drive bay, or ECB enclosure
bay is not available, place the replacement ECB on top of the enclosure.
5. If you are replacing an ECB for an array controller in a M2200 enclosure,
complete the following substeps:
a. Install a Battery Service Label on the replacement ECB as described in
the documentation that shipped with the battery.
Note: The Battery Service Label indicates the installation date ( MM/YY ) for the
replacement ECB.
b. Remove the blank bezel from the appropriate bay and insert the
replacement ECB.
Note: Do not remove the old ECB until the ECB charged LED on the replacement ECB
turns on (see Figure 64 on page 153).
