The Cisco PID UCSC-RAID-ROM55= includes the SCU upgrade ROM module and the RAID 5 key.
To install a SCU upgrade ROM module, follow these steps:
Step 1 Locate the header (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.
