6. My system appears to be leaking fl uid...
Since users are allowed to confi gure their own coolers and clamps, it is
possible a connection was not properly sealed (however unlikely). If you
can see liquid somewhere on the tubing, or at the bottom of the chassis,
computer components may need to be removed for a system test (see
Flow Testing).
If liquid should get onto another computer component, shut down the
system, and remove the component. In most cases, the hardware will be
fi ne after allowing it to dry. However, the system should not be operated
until you have discovered where the leak is coming from and can repair
the problem. Should the leak be situated somewhere in which it can not
be easily repaired, please contact our Technical Department for further
diagnostic information.
7. My computer’s BIOS gives me errors that there are no cooling fans attached...
Some motherboards will not boot, or may generate an error or alarm if
no cooling fans are attached to the CPU or motherboard chipset power
connectors. There is sometimes an option to disable these fan connec-
tions in BIOS, but you may have to boot-up with a fan attached initially to
disable this setting. If the system is not booting due to this problem, clear
the CMOS and try confi guring BIOS again.
8. The LED Display Panel gives an Error Code...
Your system LED display may specify if there is a problem with the unit. Please use the
following guide in detemining the cause of a problem:
The green LED “Power” light indicates whether the pumps are working or not. It is common
for this light to fl icker in normal operation, but it should not go out.
E1 - Alarm is sounding (temperature is 55-58ºC, or 131-136ºF). System is overheating.
E2 - System shutdown (temperature over 58ºC, or 136ºF). System is nearing critical tem-
peratures.
E3 / PO - Open pump circuit (green power LED is out). Check the slot interface board and
power control board connections.
E5 / SO - CPU temperature sensor open circuit (alarm sounds, green power LED is on).
Check the slot interface board to ensure a proper thermal probe connection.
E6 / SS - CPU temperature sensor short circuit (alarm sounds, green power LED is on).
The temperature sensor needs to be replaced.
E7 - System fault; shutdown after 10 seconds (alarm sounds, green power LED is on).
Please contact our Technical Department for further assistance.
