Chapter 1: Introduction
WARNING!
Although the RAID controller can be hot-swapped, the RAID
controller is built of sensitive components and unnecessary
tampering can damage the controller.

Special Firmware Implementations
Monitoring:
A RAID subsystem is aware of component statuses such as
those of:
1. JBOD expander
2. PSU
3. Cooling
module
4. Enclosure
thermal
5. Disk
drives
JBOD Identifier:
If connected with JBODs, the managing RAID subsystem will
sound the alarm and deliver notification messages if the
following occur:
1. JBOD ID conflict. If more than one JBOD is connected to
the managing RAID subsystem, each JBOD needs a
unique ID set by the rotary IP switch on its forearm
handle.
2. Firmware automatically disconnects a second JBOD if
the second JBOD is connected online and comes with
an ID identical to that of the first JBOD.
Cooling Module Speed Adjustment:
If any of the detected
temperature readings breaches the high temperature threshold,
the firmware running on the managing RAID subsystem
automatically forces all cooling fans to run at a higher rotation
speed.
Controller Module Interfaces
The controller module interfaces are accessed through the controller
rear-facing faceplate as shown in
Figure 1-12
