Chapter 3 Maintaining the Server

Installing or Replacing Server Components

Replacing the LSI RAID Battery Backup Unit or SuperCap Power Module

This server supports installation of one RAID battery backup unit (BBU) or one SuperCap Power Module (SCPM). The unit mounts to a clip on the removable air baffle (see Figure 3-24).

•The optional LSI BBU is available only when using the optional LSI MegaRAID controller cards. This BBU provides approximately 72 hours of battery backup for the disk write-back cache DRAM in the case of sudden power loss.

•The SCPM is available only when using the optional LSI MegaRAID-CV controller cards. This supercap module provides approximately 3 years of backup for the disk write-back cache DRAM in the case of sudden power loss by offloading the cache to the NAND flash.

Note LSI recommends that you replace the LSI BBU once per year or after 1,000 recharge cycles, whichever comes first. Verify whether BBU replacement is required by looking in the CIMC. Log in to CIMC for the server, then click Server—Inventory—Storage—Battery Backup Unit. If the Battery Replacement Required field says, “True,” then you must purchase a replacement BBU and replace it.

Warning There is danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s instructions.

Statement 1015

To replace the RAID controller BBU or SCPM, follow these steps:

Step 1 Remove a backup unit (see Figure 3-24).

a.Power off the server as described in the “Shutting Down and Powering Off the Server” section on page 3-7.

b.Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Caution If you cannot safely view and access the component, remove the server from the rack.

c.Remove the top cover as described in the “Removing and Replacing the Server Top Cover” section on page 3-8.

d.Disconnect the cable from the existing backup unit.

e.Slide the backup unit free of the clips on the air baffle mounting point (see Figure 3-24).

Step 2 Install a new backup unit:

a.Slide the new backup unit into the clips on the air baffle mounting point.

b.Connect the cable from the RAID controller to the new backup unit.

c.Replace the top cover.

d.Replace the server in the rack, replace cables, and then power on the server by pressing the Power button.
