Installing the Cache Backup Products
This chapter explains how to connect the CacheVault module to back up power units.
CAUTION
Electrostatic discharge (ESD) can damage the modules and the MegaRAID controllers. Always ground yourself,
and use a ground strap before you touch the MegaRAID controller or the module. Perform all installation work
at an ESD-safe workstation that meets the requirements of EIA-625,
Requirements for Handling Electrostatic
Discharge Sensitive Devices
. Follow the ESD-recommended practices in the latest revision of the Inter-Process
Communication (IPC) IPC-A-610, Acceptability of Electronic Assemblies, standard.
If screws are required, use an ESD-safe Phillips screwdriver to install them. Be sure the screwdriver is centered in the
screw to avoid damaging the screw head. If you exceed the maximum torque specification, you might damage the board,
connectors, or screws, and you void the board warranty.
NOTE
To protect your data, set the MegaRAID controller Write Policy to
write-through
until the battery unit is charged.
After the battery unit charges, you can change the Write Policy to
write-back
to take advantage of data caching
performance improvements.
See Handle and Dispose of CacheVault Power Modules for information about how to handle and dispose of a CVPM
properly.
See
CacheVault Module Specifications for technical specifications.
If you choose to connect the clip directly to the chassis, see Mount without the Remote Mount Board . If you choose to
make a custom clip, see Using a Custom Mounting Bracket for design details.
Attaching the CVFM04 Module to the MegaRAID Controller and by
Cable to a CVPM02 Module on a Remote Mount Board
This section describes how to attach the CVFM04 module directly to your MegaRAID controller, and then connect the
CVFM04 module by cable to a CVPM02 module on a BBU-BRACKET-05 remote mount board (sold separately). The
CVFM04 module attaches directly to the MegaRAID controller, and the CVPM02 module fits on a clip that attaches to
the remote mount board. The MegaRAID controller and the remote mount board are then installed in PCIe slots on
the motherboard. The CVPM02 module can mount locally in the system as long as sufficient airflow maintains a proper
operating temperature range. See CacheVault Module Specifications for airflow requirements.
The CVFM04 module and the CVPM02 module are used on the following MegaRAID controllers:
•
MegaRAID SAS 9361-4i
•
MegaRAID SAS 9361-8i
•
MegaRAID SAS 9380-4i4e
•
MegaRAID SAS 9380-8e
Perform the following tasks to attach the CVFM04 module directly to your MegaRAID controller, and then by cable to the
CVPM02 module on a remote mount board.
1. Remove the MegaRAID controller from the host system. See
Removing the MegaRAID Controller from the Host
Computer .
2. Attach the CVFM04 module directly to the MegaRAID controller. See Attach the CVFM04 Module Directly to the
MegaRAID Controller .
3. Install the clip on the remote mount board. See Installing the Clip on the Remote Mount Board .
4. Attach the CVPM02 module to the clip. See Attach the CVPM to the Clip on the Remote Mount Board .
