Replacing a standard storage controller and a
power fail safeguard module
WARNING!
To avoid bodily injury from hot surfaces, allow the server and its internal modules to cool before
touching them.
For some storage controllers, you can order a power fail safeguard module to prevent data loss
when power outage occurs.
A power fail safeguard module provides a flash card and a supercapacitor. When a system power
failure occurs, this supercapacitor can provide power for a minimum of 20 seconds. During this
interval, the storage controller transfers data from DDR memory to the flash card, where the data
remains indefinitely or until the controller retrieves the data.
