the battery. This might take a few minutes, after which the startup process continues. This is a one-time occurrence.

Important: You must allow the initialization process to be completed. If you do not, the battery will not work, and the server might not start.

The battery comes partially charged, at 30% or less of capacity. Run the server for 4 to 6 hours to fully charge the controller battery. The LED just above the battery on the controller remains lit until the battery is fully charged.

Until the battery is fully charged, the controller firmware sets the controller cache to write-through mode; after the battery is fully charged, the controller firmware re-enables write-back mode.

2.When you restart the server, you will be given the opportunity to import the existing RAID configuration to the new ServeRAID-8k SAS Controller.

Installing a hard disk drive

Locate the documentation that comes with the hard disk drive and follow those instructions in addition to the instructions in this chapter.

Important: Do not install a SCSI hard disk drive in this server; install only SAS hard disk drives.

The following notes describe the type of hard disk drive that the server supports and other information that you must consider when installing a hard disk drive:

vThe server 3.5-inch models support six slim 3.5-inch hard disk drives installed on Ultra-Slim hard disk drive trays for 3.5-inch drives. For a list of supported 3.5-inch hard disk drives, see http://www.lenovo.com/thinkserver.

vThe server 2.5-inch models support eight 2.5-inch hot-swap hard disk drives installed on Ultra-Slim hard disk drive trays for 2.5-inch drives. For a list of supported 2.5-inch hard disk drives, see http://www.lenovo.com/thinkserver.

vAll hot-swap drives in the server should have the same throughput speed rating. Mixing hard disk drives with different speed ratings will cause all drives to operate at the lower throughput speed.

vThe ID that is assigned to each bay is printed on the front of the server.

The following illustrations show how to install a hot-swap hard disk drive.
