For the power fail safeguard module to take effect, replace the supercapacitor before its lifespan
expires.
The supercapacitor might have a low charge after the power fail safeguard module is installed or
after the server is powered up. If the system displays that the supercapacitor has low charge, no
action is required. The system will charge the supercapacitor automatically. You can view the status
of the supercapacitor from HDM or the BIOS.
IMPORTANT:
After the supercapacitor replacement, verify that cache related settings are enabled for logical
drives. For more information, see HDM online help.
Guidelines
You can install one or multiple standard storage controllers. To install multiple storage controllers,
make sure the standard storage controllers are of the same vendor (PMC or LSI). For information
about the available storage controllers and their vendors, use the query tool available from
http://www.h3c.com/cn/Service/Document_Software/Document_Center/Server/
Use
to identify the supercapacitor available for a storage controller.

To replace the storage controller with a controller of a different model, back up data in the drives of
the storage controller and clear RAID configuration.
To replace the storage controller with a controller of the same model, make sure the following
configurations remain the same after replacement:
•
Storage controller location and cabling.
•
Storage controller model, operating mode, and firmware version.
•
BIOS boot mode.
•
First boot option in Legacy mode.
For more information, see the storage controller user guide for the server and the BIOS user guide
for the server.
If you add a storage controller and connect the controller to the front drive backplane, update the Exp
module firmware as needed after the replacement.
•
If one controller is attached to the drive backplane, use the single version firmware.
•
If two controllers are attached to the drive backplane, use the dual version firmware.
