SAN Volume Controller 2145-24F and 2145-12F expansion canister SAS ports and indicators

Two SAS ports are located in the rear of the SAN Volume Controller 2145-24F and 2145-12F expansion canister.

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.

Figure 1 has callouts to show the location of the LEDs and the port for SAS port 1:

1 Port 1 LEDs
2 Port 1 12 Gbps SAS port

Table 1 describes LED states for each of the two LEDs per SAS port. The link LED is on the left of each set of ports.

Name	Color	State	Meaning
SAS Port 1 Link	Green	OFF	No physical link connection on any phys. The connection is down.
SAS Port 1 Link	Green	ON	There is a connection on at least one physical lane. At least one of the lanes to that connector is up.
SAS Port 1 Fault	Amber	OFF	No fault. All four physical lanes have a link connection.
SAS Port 1 Fault	Amber	ON	This value indicates a number of different error conditions: One or more, but not all, of the four physical lanes are connected. Not all four physical lanes are at the same speed. One or more of the connected physical lanes are attached to an address different from the others.
SAS Port 2 Link	Green	OFF	No link connection on any physical lanes. The connection is down.
SAS Port 2 Link	Green	ON	There is a connection on at least one physical lane. At least one of the lanes to that connector is up.
SAS Port 2 Fault	Amber	OFF	No fault. All four physical lanes have a link connection.
SAS Port 2 Fault	Amber	ON	This value indicates a number of different error conditions: One or more, but not all, of the four physical lanes are connected. Not all four physical links are at the same speed. One or more of the connected physical links are attached to an address different from the others
