Although the RAID controller can be removed, the only time you should touch the
controller itself is to replace the memory module or to install the memory module.
The RAID controller is built of sensitive components and unnecessary tampering can
damage the controller.
Controller Module Interfaces
The subsystems provide external interfaces to host computers and management
station(s) through the RAID controller's rear-side faceplate as shown in Figure 1-15.
Note that the rear-facing faceplates of the 12 BAY and 8 BAY models look identical.
• Host Ports
SCSI-320 Host Ports: Two SCSI-320 host channels connect the subsystem to the
host computers equipped with SCSI-320 compatible adapters through the dual-stack
VHDCI connectors. The dual-stack connectors facilitate cascade connections for
configurations such as host clustering or cascading with another RAID subsystem.
This subsystems come with preset configurations for channel mode and channel ID
settings, and should be sufficient for most applications.
• Ethernet Port
All controller modules on the subsystems come with a single 10/100BasedT RJ-45
Ethernet port. The Ethernet port is used for local or remote management through the
network using the RAIDWatch GUI manager or Telnet protocol.
