2U expansion canister LEDs

Each 2U expansion canister has three LEDs that provide status and identification for the expansion canister.

Note: The 2U expansion enclosures are only supported by the SAN Volume Controller 2145-SV1 and SAN Volume Controller 2145-DH8 control enclosures. The 2145-SV2 and 2145-SA2 control enclosures do not support any epxansion enclosures.
Three LEDs are located in a horizontal row on the right side (when viewed from the rear) of the 2U expansion canister. Figure 1 shows the expansion canister LEDs, and Table 1 describes the LEDs.
