2U expansion canister SAS ports and indicators

Two SAS ports are located in the rear of the each 2U (-12F and -24F) 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.
SAS ports are numbered at the bottom of the port, with 1 on the left and 2 on the right, as shown in Figure 1. Use of port 1 is required. Port 2 is not used. Port 1 connects four data channels.
