Features

The MegaRAID LSIiBBU07 / LSIiBBU08 is an innovative, industry-exclusive module and offers intelligent monitoring capabilities, accessible via ServerView

RAID.

The capabilities of the LSIiBBU07 / LSIiBBU08 include monitoring the battery status and power levels as well as the ability to recondition and calibrate the battery for improved reliability. It maintains data in the cache in the case of powerfail (see data sheet for hold time duration).

4.2.5.2

Installation

The LSIiBBU07 / LSIiBBU08 supports remote connection to the Modular RAID

Controller "RAID Ctrl SAS 6G 5/6 512 MB (D2616)".

The LSIiBBU07 / LSIiBBU08 is not installed directly on the RAID controller.

Instead, use one of the supplied cables to connect the LSIiBBU07 / LSIiBBU08 to the RAID controller. The battery backup unit must be mounted inside the chassis.

I

Because server chassis vary, there is no standard mounting option that is compatible with all the different system configurations. Refer to your server’s Options Guide or Upgrade and Maintenance Manual for mounting details.

Therefore, the LSIiBBU07 / LSIiBBU08 battery kit contains only the battery and a set of cables, allowing you to customize the location of the remote battery to provide the most flexibility within different environments.

To install the LSIiBBU07 / LSIiBBU08 remotely to the RAID controller, proceed as follows:

1. Ground yourself, then remove the LSIiBBU07 / LSIiBBU08 from its package.

2. Secure the LSIiBBU07 / LSIiBBU08 to the server chassis as described in the server documentation.

3. Insert the battery pack harness connector (at the end of the colored wires)

into the J4 connector (see figure 13 ) on the bottom of the

LSIiBBU07 / LSIiBBU08.

4. Connect the cable from the cable connector (see

figure 13

) on the

LSIiBBU07 / LSIiBBU08 to the BBU connector on the RAID controller.
