Chapter 5
First-Time Configuration
5-5
A battery module whose status shows one or more + signs can support cache
memory for 72 hours. As long as one or more + signs are displayed, your battery is
performing correctly.
Your lithium ion battery should be changed every two years if the unit is
continuously operated at 25 degrees C. If the unit is continuously operated at 35
degrees C or higher, it should be changed every year. The shelf life of your battery is
three years.
Note –
The RAID controller has a temperature sensor which shuts off battery
charging above 54 degrees C. When this happens, the battery status may be reported
as BAD, but no alarm is written to the event log since no actual battery failure has
occurred. This behavior is normal. As soon as the temperature returns to the normal
range, battery charging resumes and the battery status is reported correctly. It is not
necessary to replace or otherwise interfere with the battery in this situation.
For more information, see
“Environmental Requirements” on page 2-3
for the
acceptable operating and nonoperating temperature ranges for your array.
For information on the date of manufacture and how to replace the battery module,
refer to the
Sun StorEdge 3000 Family FRU Installation Guide
.
