3.21x2 Cables and Connections

This section contains information about SCSI and power connections for one StorEdge A3500 with two StorEdge D1000 disk arrays.

Note –The 1x2 configuration is not qualified on the A3500FC controller module.

In the 1x2 configuration, the controller module can be either on top of or below the two disk arrays. Both configurations are described in this section.

Tip –Do not place the controller module at the bottom of the rack because the controller board diagnostic LEDs will not be visible.
