LEDs on the rear of the expansion enclosure
Figure 123 shows the rear view of a 2077-92F expansion enclosure. LEDs on the
rear of the enclosure provide information about each fan module, each expansion
canister, and SAS links.
The expansion enclosure has four fans. Each fan has one LED; for example,
Figure 123 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 123 also shows, the expansion enclosure contains two expansion
canisters. Each expansion canister contains its own set of LEDs, as shown in
Figure 124 on page 141. The LEDs provide status information about the expansion
canister itself and the SAS connections.
