Figure 124. LEDs on the back of the expansion enclosure
The expansion enclosure has four fans. Each fan has one LED; for example,
Figure 124 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 124 also shows, the expansion enclosure contains two expansion
canisters. Each expansion canister contains its own set of LEDs, as shown in
Figure 125. The LEDs provide status information about the expansion canister itself
and the SAS connections.
