AssuredSAN 4004 Series FRU Installation and Replacement Guide 45
Verifying component operation
Examine PSU module status as indicated in the table below.
LEDs for a PSU are located in the top right corner of the module face, as shown in Figure 24 on page 43.
The top LED corresponds to LED number (1) above, and the bottom LED corresponds to number (2) above.
If the Voltage/Fan Fault/Service Required LED is illuminated amber, the PSU module has not gone online,
and likely failed its self-test. Remove and reinstall the PSU module. In addition to viewing the PSU LEDs,
verify that the cooling fans are spinning. Also see Using management interfaces on page 57 as an
alternative to physically observing LEDs to verify component operation.
Replacing ear components
Before you begin
CAUTION: Verify that you have the proper FRU kit (left or right) for the ear components being replaced.
See CAUTION bullets regarding “electrostatic discharge” and “anti-static protection” on page 20 .
Enclosure ear kit FRUs are available for the left and right ears of the chassis front panel. The following
replacement procedure applies to ear kits provided with the 2U24 and 2U12 enclosure models,
respectively. Refer to the following illustrations pertaining to your product ear kit. Illustrations in ear kit
replacement procedures show front panel views of each enclosure, and ear bezel components are properly
aligned for attachment to the ears on the front panel of the enclosure.
2U24 chassis ears
Figure 26 shows the left ear flange of a 2U24 model with the LED circuit board installed. The enclosure
bezel is removed to reveal the left ear and SFF disks. See Attaching and removing the enclosure bezel on
page 22 ( Figure 11 ) for bezel attachment and removal details.
