Node Canister Sas Ports And Indicators - IBM Storwize V7000 Troubleshooting And Maintenance Manual

Node canister SAS ports and indicators

Two serial-attached SCSI (SAS) ports are located side by side in the rear of the
node canister.
The SAS ports are numbered 1 on the left and 2 on the right as shown in Figure 17.
Port 1 is used if you add one expansion enclosure. Port 2 is used if you add a
second expansion enclosure. Each port provides four data channels.
Note: The reference to the left and right locations applies to canister 1, which is
the upper canister. The port locations are inverted for canister 2, which is the lower
canister.

SAS ports must be connected to Storwize V7000 enclosures only. See "Problem:
SAS cabling not valid" on page 49 for help in attaching the SAS cables.
Four LEDs are located with each port. Each LED describes the status of one data
channel within the port. The data channel number is shown with the LED.
