Bosch Security System

The RAID controller module contains a main circuit board, a preinstalled 256MB capacity or 

above DDR RAM DIMM module and the controller module interfaces. The controller module 

contains no user-serviceable components. Except when installing/upgrading the cache mem-

ory inside, the controller module should never be removed or opened.

The heart of the RAID controller subsystem is the 320MB per second SCSI-to-SATA controller 

board. The controller comes with two (2) pre-set SCSI-320 host channels, CH0 and CH1. The 

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.

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.

Controller Module Interfaces

•

Host Ports: Two (2) SCSI-320 host channels (CH0 and CH1 in Figure 2.9) connect the 

subsystem to the host through two (2) dual-stacked VHDCI SCSI connectors.

•

Ethernet Ports: A single 10/100BaseT Ethernet port (located next to COM2) is used for 

remote management through the network.

•

COM ports: The controller module comes with two (2) COM ports. One port is used to 

access the controller-embedded configuration utility through the network, and the other 

connects to a UPS connection. .

•

Levers: Two (2) levers located in the sides of the controller board rear panel provide easy 

controller module installation and secure the controller module in place.

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

itself is to install the memory modules. The RAID controller is built of sensitive components 

and unnecessary tampering can damage the controller.
