ECB SBBs

The external cache battery (ECB) SBB provides power to the RAID array controller cache
module if system power fails. The cache module in turn provides power to the ECB
during normal operation. Compaq supplies two versions of ECBs: a single-battery ECB
for single-array controller configurations and a dual-battery ECB for dual-redundant array
controller configurations. Each battery has a power connector, status LED, and battery
disable switch (see Figure 1–17).
To check the ECB status, look at the battery status LED (one for each cache module) for
the appropriate indication (see Figure 1–17 and Table 1–3).
