Figure 64. LEDs on the back of the expansion enclosure
The expansion enclosure has four fans. Each fan has one LED; for example, Figure 64 on page 52 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 64 on page 52 also shows, the expansion enclosure contains two expansion canisters. Each
expansion canister contains its own set of LEDs, as shown in Figure 65 on page 52. The LEDs provide
status information about the expansion canister itself and the SAS connections.
