Introduction
Thank you for purchasing Rackmaster System’s Aurora Fault
Resilient Series Computer Chassis.
The Aurora FRS chassis is a rackmountable unit with several
options available for mounting different types of processing equipment. From ATX motherboards of all styles, to backplane systems up
to 20 slots, this chassis is designed with the flexibility to accommodate
all of your requirements. Most importantly, the FRS chassis is completely fault tolerant. The “hot swap” power supplies and fans are
easily replaced without taking the system down and without the use of
any tools. The chassis also utilizes a unique positive pressure cooling
system that provides proper cooling for any user configuration. A door
is supplied with all configurations which is lockable and includes a
1/2” filter element that is easily cleaned and replaced without any
tools.
The Aurora FRS chassis includes a front panel LCD which
clearly displays the status of the monitored functions in near real time.
An audible alarm will sound in the event of a failure and the chassis
provides a means to latch to a remote alarm/pager device. This chassis
also monitors and warns of failing fans and system over-temperature in
addition to the power supply voltages.
Rackmaster Systems hopes you enjoy your purchase. Please

Aurora FRS Monitoring / Alarm Features
The Aurora FRS chassis has built-in monitoring and alarm
features which are described in the following sections.
Note: Upon initial start-up or system reset, the chassis will do a selfcheck and test the alarm system buzzer.
LCD Status Display
The LCD panel on the Aurora FRS chassis is used to display
the status of the critical chassis functions. The display scrolls through
each of the monitored functions. The results, either “PASS” or
“FAIL”, are shown on the display. The display contrast can be adjusted by opening the front door and turning the potentiometer with a
small screwdriver. (Please refer to the diagram on Page 5 for the
LCD contrast adjustment location.)

Power Supply Monitoring
The Aurora FRS chassis has the capability to do power supply
testing. All voltages of the supply are continuously monitored. If any
of these voltages fail or fall out of specification, a failure will be
logged. This will cause the failure to be displayed on the front LCD
panel, indicating which supply failed. An audible alarm will also sound
to warn of a failure.
Fan Monitoring
The Aurora FRS chassis also monitors the rotation of the card
cage cooling fans. This includes, on the 620W power supply versions,
the capability to monitor the power supply housing fans as well. If the
fans fall below a preset fan speed, an error is displayed on the LCD
panel indicating which fan failed and the audible alarm will also sound.
Over Temperature Monitoring
Testing for an over temperature condition is also a feature of
the Aurora FRS chassis. If the internal temperature rises above a
preset temperature, an audible alarm will sound and the LCD panel
will indicate the over temperature condition.
Note: All alarm conditions may be stored and the audible
alarm silenced by depressing the alarm system reset button. (Please refer to the diagram on Page 5 for the reset
button location.)

Aurora FRS Chassis Operation
The Aurora Fault Resilient Series chassis has a hot-swappable
power supply system and fan system. The following section is to help
you understand their operation.
Power Supply Replacement
The Aurora chassis continuously monitors all of the voltages
within the power supply. Because the unit has current sharing capability, the system will remain operational even though one of the supplies
is shut down. If a failure occurs in either power supply, on any of the
supply voltages, an error code is generated. The instant a power
supply problem is detected, the Aurora chassis will activate the red
“FAIL” LED located on the front panel and the LED on power supply
shuttle will change to red also. An audible alarm is also sounded to
alert of the failure. The failed power supply module must be replaced
as soon as possible.
The alarm may be silenced by pressing the system monitoring
reset button located inside the front door on the front panel. Please
refer to the diagram on Page 5 for the reset button location.)
Pressing the reset button quiets the audible alarm, logs the error
in memory and restarts the failure detection circuitry. This allows the
system to detect other errors while the power supply is down.
Locate the bad power supply on the front of the unit by the red
“FAIL” indicators on the power supply and on the front panel. Turn
the power switch, with the “FAIL” indicator lit, to the off position.

It is suggested that spare power supply shuttles are purchased and kept on site for emergency replacement. If a supply is
not readily available on site, your system supplier must be contacted
immediately for a replacement power supply. If not purchased with the
original chassis, the chassis serial number and model type will be
required to acquire a new power supply shuttle Damage may occur to
the chassis if an incorrect power supply shuttle is installed. Once a
replacement power shuttle is ready, the following steps should be taken
for replacement;
1.) Open the chassis door.
2.) Confirm the power shuttle you are removing has its power shut off.
3.) Unlock the failed power supply module with the power supply key
supplied with the chassis. Slide the failed power supply module out of
the housing.
4.) Before inserting a new power supply module, insure the input
selector switch (located on the rear of the power supply module), is set
for the correct voltage for your area. Normally 110V for U.S. locations
or 220V for International locations. If in doubt, contact your power
company to determine the correct setting. Failing to set the correct
input voltage will result in serious damage to the power supply and/
or chassis.
5.) Gently push in the new power supply module. The power supply
module will seat into the housing. Once that is accomplished, lock the
power supply into the chassis with the keylock on the power supply
module.
6.) Return power to the replaced power supply by turning on the
power switch for that supply.
7) Confirm all “Pass” LED indicators are lit.

Fan Shuttle Replacement
If an over-temperature condition is sensed, an audible alarm
will sound and an error condition will be displayed on the front panel
LCD. Check to see if the internal power supply fans are rotating and,
on the quad power supply version, that both external housing fans are
rotating. If one of the power supply fans is malfunctioning, return to
the previous section on power supply failures and follow the instructions for replacing a power supply module. If one of the card cage fans
or the quad power supply housing fans is malfunctioning an error
condition will be displayed on the front panel LCD. Proceed to the
following instructions on swapping fan shuttles.
It is suggested that spare fan shuttles are purchased and
kept on site for emergency replacement. If a fan shuttle is not
readily available on site, your system supplier must be contacted
immediately for a replacement fan shuttle. The chassis serial number
and model type will be required to acquire a new fan shuttle.
Once the replacement fan shuttle is ready, the following steps should
be followed for replacement.
1) Remove the small panel on top of the lid by pulling up on the two
release levers to expose the fan shuttles inside of the chassis. When
facing the front of the chassis, the fans are numbered from left to right,
with fan # 1 to the left and fan # 3 to the right.
2) Unlatch the failed fan shuttle by pulling the fan shuttle release lever
up.
3) Then remove the shuttle by pulling the fan shuttle out of the chassis. If the fan is still rotating, be careful not to come in contact with
the blades.
4) Replace with the new fan shuttle by reversing the previous process.

Aurora FRS Filter Maintenance
A filter element is held inside the door. This filter is designed
to remove dust and other airborn particles before entering the chassis.
The filter should be cleaned periodically, depending on the system’s
environment. A dirty filter can eventually lead to temperature increases
within the chassis by restricting the airflow.
To remove the filter for cleaning, simply grasp the filter by the
center and pull out. The filter may be cleaned by rinsing under clean
water or mild soap and water if necessary. Assure the filter is dry
before replacing into the door. Replace the filter by tucking the filter
element back into the filter holder on the back of the door. Check to
see that all of the cooling vents on the front of the door are being
filtered. If not, adjust the filter element position.
Aurora FRS Remote Monitoring Port
The Remote Monitoring Port for the FRS Aurora chassis is located
on the rear panel (see page 6 for location). It is a standard DB9 female
connector. When an error occurs in the chassis, a signal is sent to this port
to allow the use of third party equipment to monitor this port and report an
error condition. The monitoring port gives you two options for operation, a
relay contact closure or a TTL out signal. The following diagram shows
the pin locations for the two signals. For the relay contact closure use pins
3 and 8. For the TTL out use pins 2 and 7.
