Chapter 5
Installing the Intelligent
Battery Backup Unit
Remotely
This chapter explains how to connect the the intelligent Battery Backup
Unit (iBBU) remotely to the ServeRAID-MR10is SAS/SATA Controller.
The ServeRAID-MR10is SAS/SATA Controller comes with the
ServeRAID-MR10is iBBU already connected directly to the board. You
can remove the iBBU and use a daughtercard and a cable to connect
the iBBU remotely to the controller. The daughtercard connects to the
controller and then connects to the iBBU using the 12-inch cable. The
battery backup unit must be mounted inside the chassis within 10 inches
of the controller.
Attention: Electrostatic discharge can damage the iBBU and the
controller on which it is installed. Always ground yourself
and/or use a ground strap before you touch the controller
or the iBBU. 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 IPC-A-610.
