Subsystem Components

1-10

The two models’ rear-facing controller faceplates look identical.

WARNING!

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.

All external interfaces that connect to external devices are located on the controller

module rear panel. The interfaces are listed below.

• Host Ports

FC-4G Host Ports: The RAID controller module has two (2) SFP sockets labeled FC-

CH0 and FC-CH1. Two FC-4G host channels connect the subsystem to the host

computers equipped with FC-4G Fiber-optic compatible adapters. The Fibre Channel

host ports receive SFP transceivers and then to LC-type cables. These SFP ports can

auto-negotiate the speed and determine the data transmission rate.

NOTE:

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.
