Battery-Backed Write Cache Enabler
The Smart Array 5i Battery-Backed Write Cache Enabler, also known as the battery
module, provides transportable data protection, increases overall controller
performance, and maintains any cached data for up to 72 hours without external
power. It provides the system with a means for storing and saving data in the event of
an unexpected system shutdown. The NiMH batteries in the battery module are
continuously recharged through a trickle-charging process whenever the system
power is on. Under normal operating conditions, the battery module lasts for 3 years
before replacement is necessary.
To install the battery module:
1. Power down the server blade and remove it from the server blade enclosure.
Refer to the “Preparation Procedures” section in this chapter.
2. Remove the access panel. Refer to “Preparation Procedures” in this chapter.
3. Install the battery module onto the standoffs on the system board. Be sure the
battery module seats firmly, and turn the standoffs to secure.
NOTE: If you purchased the Battery-Backed Write Cache Enabler as an option, you need to
attach the plastic casing separately.
