LEDs on the rear of the expansion enclosure
Figure 60 on page 60 shows the rear view of a 2072-92G, 2072-F92 expansion enclosure. LEDs on the
rear of the enclosure provide information about each fan module, each expansion canister, and SAS links.
Figure 60. LEDs on the back of the expansion enclosure
The expansion enclosure has four fans. Each fan has one LED; for example, Figure 60 on page 60 shows
the location of the LED ( 5 ) for fan number four. When a fan is operating normally, the LED is not lit. If a
fault is detected, the amber LED is lit.
As Figure 60 on page 60 also shows, the expansion enclosure contains two expansion canisters. Each
expansion canister contains its own set of LEDs, as shown in Figure 61 on page 61. The LEDs provide
status information about the expansion canister itself and the SAS connections.
