Components
This section provides a description of each of the major components that
comprise the imageRAID Series Storage System.
Front Bezel
The front bezel houses the Status LEDs, Drive LEDs, and alarm reset button. When
removed, the user has access to the disk drives. The front bezel can be installed or
removed without interruption to system activities.
Embedded within the front bezel is the electronic package that provides the
communication with the SES controller. The SES controller manages the signals to
the front panel through a smart interface. Power is applied to the front bezel
through the interface edge connector, where a control circuit monitors the bezel
for proper connection. When the bezel is properly installed and power is applied
to the enclosure, the bezel is immediately energized.
Refer to “Control and Monitoring” on page 18 for details on the monitoring
functions.
Removable Front Bezel
To remove the bezel and gain access to the disk drives, use a Phillips screwdriver
to release both bezel fasteners, then grasp and remove the bezel. The fasteners
rotate one-quarter turn clockwise to lock and counter-clockwise to unlock.

AC Power
4
AC Power
The power system consists of two 350-watt hot-pluggable power supplies, each
with independent AC power cords and cooling fans. This power system provides
the enclosure with “N+1” redundant power. Each power supply has auto-switching
circuitry for use with either 100V or 240V AC systems.
Power Supply
Power is applied to the enclosure by pressing each of the two power supply
On/Off switches to their “On” position. A Power On LED located on each power
supply will be illuminated indicating that AC power has been applied. The front
bezels’ Power On LED will also be illuminated indicating that power has been
applied.
Each power supply also incorporates an amber general Fault LED. If the power
supply is installed and power is not applied to the power supply or the power
supply cooling fan fails, the Fault LED will illuminate, along with an audible alarm.
The front bezels’ Power Supply Status LED will illuminate green when both
power supplies are on and operating normally. If only one power supply is
operational, the Power Supply Status LED will be illuminated amber.
Each power supply has an AC Power Cord Module. The module has a power
cord bale incorporated into the design to secure the power cord once it has been
properly inserted. The bale prevents inadvertent disconnects.

Cooling Fan Module
5
Cooling Fan Module
The cooling system consists of two high-performance (80-CFM) cooling fans
mounted in a single fan module which slides into a bay at the rear of the
enclosure. The design of the fan module provides for an easy-to-install user-
replaceable component in a live environment without interruption of service.
If any one fan should fail, cooling redundancy and efficiency are degraded. The
cooling fans and enclosure temperature are constantly monitored by the SES
processor for fault conditions. In the event of a fault condition the front panel Fan
Status LED will change from a green state to a solid amber state in the case of a fan
failure, or to a blinking amber green state in the case of an over-temperature
condition. In both cases an audible alarm sounds. The SES processor will also
provide notification data to monitoring software, such as StorView.
WARNING: Do not operate the enclosure for extended periods of time (greater
than 5 minutes) with the cooling fan module removed.
Cooling Fan Module
The enclosure has temperature sensors in three different areas, the drive bay, the
imageRAID Controllers, and the power supplies. There are several steps the storage
system performs to prevent component damage due to over temperature
conditions.

If the drive bay area reaches a temperature of 50°C (122°F) an audible alarm will
sound, the front panel Fan Status LED will toggle amber green, and the monitoring
software will post a warning message. These notifications give the user a warning
that some condition is causing the enclosure temperature to exceed the preset
value, and an action is required by the user to determine the cause and take
corrective measures. It may be due to a blockage of air flow or a low fan speed.
If any controller reaches a temperature of 65°C (149°F) an audible alarm will
sound, the front panel Fan Status LED will alternate amber and green, and the
monitoring software will post a warning message. If the temperature on any
controller continues to rise and reaches 71°C (159°F), the controller will flush its
cache and shutdown. If it is the only controller (Simplex mode) or the only
remaining controller (surviving controller from a failed over operation) then the
controller will also spin down the disk drives at this temperature.
If any power supply reaches 85°C (185°F) the power supply will shut down.
The SES Controller card has a firmware-based VT-100 interface which provides an
option to manage fan speed. This option provides a whisper mode fan operation
for noise sensitive environments. When enabled (default), and based on a set of
conditions, the software will manage the cooling fans RPM speed to maintain the
enclosure temperature while minimizing noise levels. Refer to “Enclosure Fan
Speed Control” on page 122 for more details on using this option.
A manual override of the fan speed control is available for special circumstance
environments. Referring to the illustration on the preceding page, two jumpers are
provided on the fan module printed circuit board to override the software control
of the fan speeds. This hardware setting routes full power voltage to the fans for
maximum operational speed, which is greater than the maximum speed set by the
automatic software control. This configuration is normally used when fan speed
noises are not an issue, and the ambient operating temperature is at or above 30°C
(86°F), thus ensuring that maximum available cooling is being provided.
The jumpers JP1 and JP2 by default are offset, which enables the automatic fan
speed control. The jumper JP1 controls Fan 0 and JP2 controls Fan 1. Placing the
jumper on both pins for each jumper will override the automatic setting and
configure the fans to maximum power.

SES Controller Card
WARNING: The SES Controller card is NOT HOT SWAPPABLE. You must POWER
DOWN the enclosure prior to removing or inserting this card.
The SES Controller card provides the built-in environmental and system status
monitoring. It also houses the switches for setting the drive spin up options. This
card is installed at the rear of the enclosure in the lowest slot below the two Disk
I/O cards.
The SES processors continuously monitor the enclosure for temperature status,
fan status, power supply status, and FC loop status. The processors are
responsible for reporting environmental and system status to the front bezel
LEDs/audible alarms, SES Monitoring software (VT-100), and external monitoring
software such as StorView.
SES Controller Card
At power up, the SES processors will read the switch settings and execute a
self-test. The cards’ firmware also contains software functions for enclosure
monitoring and management. This firmware is flash upgradeable using the SES
RS-232 Service port located on the card face plate. Refer to “Uploading SES
Controller Card Firmware” on page 119 for more details.
The SES protocol uses the drives installed in slots 1 and 7 to maintain its
communication link. You must install drives in both of these slots to ensure fault
tolerance for the SES communications link.

Below is an illustration depicting the drive slot identification. Drive slot numbers
are not the drive device IDs. Drive slots appearing in gray are the SES
communication slots.
Drive Slot Location
Drive Device ID Settings
Located on the SES Controller card face plate are a set of switches. These
switches will configure the enclosure base Fibre address which configures the
disk drives in each drive slot with a device ID, as well as drive delay spin-up and
remote spin-up options. The default settings is all switches are set to their DOWN
position.
SES Controller Card Switches
The left three switches (AD0, AD1 and AD2) will configure drive slots with a
series of pre-determined device IDs. Refer to the table below:
