Hard-Drive Indicator Patterns
Your system supports two 2.5 inch SSD, SAS or SATA hard drives.
NOTE:
SSD/SAS/SATA hard drives cannot be mixed within a blade.
The hard-disk drives plug into the hard-drive backplane inside the blade. On blades with a diskless configuration, all
hard drive slots must be filled with hard-drive blanks, and the hard-drive backplane must still be installed to maintain
proper airflow.
The hard-drive indicators display different patterns as drive events occur in the system.
NOTE:
The blade must have a hard drive or a hard-drive blank installed in each hard-drive bay.
Figure 2. Hard-Drive Indicators
1. hard-drive activity indicator (green)
2. hard-drive status indicator (green and amber)
NOTE:
If the hard drive is in Advanced Host Controller Interface (AHCI) mode, the status LED (on the right side)
does not function and remains off.
