Battery module
Batteries provide backup power to maintain the contents of the controller cache when AC power is
lost and the storage system has not been shutdown properly. When fully charged the batteries can
sustain the cache contents for to 96 hours. Three batteries are used on the EVA8400 and two batteries
are used on the EVA6400.
Figure 14
illustrates the location of the cache batteries and the battery
status indicators. See
Table 9
for additional information on the status indicators.

The table below describes the battery status indicators. When a battery is first installed, the fault
indicator goes on (solid) for approximately 30 seconds while the system discovers the new battery.
Then, the battery status indicators display the battery status as described in the table below.
