Step 12: Verify Hard Disk Drive LEDs

Each Ultra2 hard disk drive module has two LED apertures on its front, one for
power status and one for activity status, as shown in Figure 2-33.
Figure 2-33. LED Apertures on Ultra 2 Hard Disk Drive Module
Light pipes on the module transmit light to these apertures from LEDs on the
inside rear of the hot-swap mass storage cage. Verify that the LEDs show the
correct power status and activity status for all of the disk drive modules that you
installed:
1. Turn on power to the HP NetServer and display monitor.
2. During the Power On Self Test (POST) early in the boot sequence, watch
the two LED apertures on each hard disk drive module. All the LEDs
should display the following rapid sequence of colors simultaneously:
All LEDs amber
All LEDs green
All LEDs red
All LEDs flash amber during some self tests
All LEDs green or red
