LEDs on the rear of the expansion enclosure
Figure 146 on page 134 shows the rear view of a 2145-92F expansion enclosure. LEDs on the rear of the
enclosure provide information about each fan module, each expansion canister, and SAS links.
Figure 146. LEDs on the back of the expansion enclosure
The expansion enclosure has four fans. Each fan has one LED; for example, Figure 146 on page 134
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 146 on page 134 also shows, the expansion enclosure contains two expansion canisters. Each
expansion canister contains its own set of LEDs, as shown in Figure 147 on page 134. The LEDs provide
status information about the expansion canister itself and the SAS connections.
