Installing a SCU Upgrade ROM Module For Embedded RAID SAS Support

The SCU Upgrade ROM module contains a chip on a small circuit board. This module attaches to a motherboard header. This chip upgrades the standard four-drive SATA support to add SAS support for up to eight SAS or SATA drives.

To install a SCU upgrade ROM module, follow these steps:

Step 1 Locate the header labelled “PBG DYNAMIC SKU” under any cables that are routed along the chassis wall (see Figure C-1).

Step 2 Align the connector on the SCU upgrade ROM module with the pins on the header, then gently push the connector onto the pins.

Step 3 Replace the top cover.

Step 4 Replace the server in the rack, replace cables, and then power on the server by pressing the Power button.

Step 5 Continue with either Installing a Software RAID Key Module for Embedded RAID 5 Support, page C-10or Enabling the Embedded RAID Controller in the BIOS, page C-10.
