Connecting two Expansion shelves to a system that has one existing Expansion shelf
The new Expansion shelves connect to the existing Expansion shelf and to the Primary shelf with SAS3 cables. The new shelves do not connect directly to the compute nodes.
Note:
To connect the new Expansion shelves
- Verify that all compute nodes, the Primary shelf, and the existing Expansion shelf are off and that the power cords are unplugged.
Do not remove the cables between the compute nodes, the Primary shelf, and the existing Expansion shelf.
- Identify the single SAS-3 port on the right side of each controller module in the Primary Shelf.
- Identify ports A and C in each I/O module in the Expansion shelf. Port B is not available for use.
- Connect the cables as follows:
Unplug the cable on the Primary shelf right I/O module where it connects to port A on the existing Expansion shelf right I/O module.
Connect the unplugged end of the cable to SAS port A in the right-hand I/O module of the farthest new Expansion Shelf.
Attach the end of one cable to SAS port C in the left-hand I/O module of the existing Expansion shelf.
Attach the other end of the cable to SAS port A in the left-hand I/O module of the closest new Expansion shelf.
Attach one end of the second cable to SAS port A in the right-hand I/O module of the existing Expansion shelf.
Attach the other end of the cable to SAS port C in the right-hand I/O module of the closest new Expansion shelf.
Attach the end of another cable to SAS port C in the left-hand I/O module of the closest new Expansion shelf.
Attach the other end of the cable to SAS port A in the left-hand I/O module of the farthest new Expansion shelf.
Attach one end of the second cable to SAS port A in the right-hand I/O module of the closest new Expansion shelf.
Attach the other end of the cable to SAS port C in the right-hand I/O module of the farthest new Expansion shelf.
- Verify the final cable configuration.
The following figure shows the cabling diagram for a two-node configuration:
The following figure shows the cabling diagram for a single-node configuration:
- Connect the power cords of all devices as described in this section.
- Turn on the devices in the proper sequence as described in this section.
- Add the new disk space as described this section.
