| CAUTION! |
| Although the RAID controller can be removed, the only time you should touch the controller |

| The heart of the RAID controller subsystem is the 320MB per second |
| board. The controller comes with two (2) |
| subsystem connects to the host through a VHDCI SCSI input connector, while the output con- |
| nector is ready to connect external devices. (See Figure 2.9) |
| The docking connector at the rear of the controller board is used to connect the controller |
| module to the backplane board. A DDR RAM DIMM socket is strategically placed in an easily |
| accessible location on the controller board for easy insertion of the DDR RAM DIMM module. |
2.5.4 | Controller Module Interfaces |
| All external interfaces that connect to external devices are located on the controller module |
| rear panel shown in Figure 2.9. The interfaces are listed below. |
