FAS2240, special attention needed

The 2240 controller module has two onboard 6GB SAS ports, 0a and 0b, with the 0b port being on the left of the controller module. This is a change from standard NetApp badging, which follows a left to right naming convention.

The SAS cable routing rules require that the square port be located on the left and the circle port be located on the right, with the circle being connected to the top of the storage stack. In the case of the 2240 series, the 0a port functions as an expander for the internal disks and therefore must be connected to the top of the stack, leaving it as the circle port.
