If you are installing FBDIMMs in an online spare or mirrored configuration, use RBSU ("HP ROM-Based
Setup Utility" on page 62) to configure this feature.
For more information about LEDs and troubleshooting failed FBDIMMs, see "Systems Insight Display LEDs
and internal health LED combinations (on page 15)."
Hot-plug SAS hard drive options
When adding hard drives to the server, observe the following general guidelines:
• The system automatically sets all device numbers.
• If only one hard drive is used, install it in the bay with the lowest device number ("SAS device
numbers" on page 16).
• Hard drives must be SFF types.
• Drives should be the same capacity to provide the greatest storage space efficiency when drives are
grouped together into the same drive array.
Installing a hot-plug SAS hard drive
1. Remove the SAS hard drive blank.
