| The
system (Server, RAID, etc.) doesn't work nor does the power
supply. |
| |
Check
the following:
- ATX
or AT?: The power supply with the ATX form factor is
supposed to connect with motherboard by 20 pin or 24
pin ATX main power. So, please check the configuration
and make sure the I/O switch is on. When you use the
RAID or AT system, please check all connections. And
the on/off push bottom or the switch is on.
- Minimum
load: Check the specification of power supply. Does
it meet the minimum load for system? If so, then do
not test ON/OFF of system, only with the power supply
& +12V DC fan.
- Short
Current Protection: The peripherals of power supply
have the short conditions and power supply is latched
into the off status.
|
| |
|
| The
power supply works normally, but the monitor has no signal. |
| |
-
The VGA card is too old to support the motherboard.
-
Conflicts with configuration. Check the configuration.

|
| |
|
| Why
does the system restart during the starting procedure? |
| |
OCP, OVP or OPP, occurs as the power supply works.
- OCP
- Over Current Protection
- OVP
- Over Voltage Protection
- OPP
- Over Power Protection
For
example: The +12V of PS offers maximum 9 amps. The system
is installed with 4 SCSI hard disks (each unit needs 2.5
peak amps). So, total output amps of +12V at start up
is 10 peak amps. When the PS executes the auto recovery
procedure, you will see the system restart.
|
| |
|
| The
WOL (Wake On Lane) doesn't work. |
| |
- The
+5VSB of power supply could not offer enough current
for the system.
- The
BIOS or jumper (PWR Up On Modem ACT) on motherboard
is disabled.
|
| |
|
| There
are two types of connectors on INTEL motherboard; 24-pin
and 20-pin. Can they be compatible? |
| |
They
are different pin assignments. Please do not plug 20-pin
connector into 24-pin. It will damage the server board with
plugging wrong position. |
| |
|
| The
system does not work after the chassis has been opened. |
| |
The
server board supports chassis intrusion monitoring. The
server board recognized an open switch as a chassis open
condition. If the chassis intrusion detection jumper is
disabled, the switch is bypassed, and the BMC does not monitor
if the chassis has been opened. |
| |
|
| The
system does not work after adding a new SCSI hard disk or
replacing VGA with new one. |
| |
Check the following conditions |
| |
A)
Server system |
|
Check
following Setup Utility/ Configure on the server board:1.
Conflicts in the configuration occur if:
- A
device that you installed requires the same resource
as another
device. (For example, a conflict occurs when two adapters
that try to write to the same address space.)
- The
server board doesn't come with the CPU, if the CPU is
PIII 600MHZ, but server board offers mostly 500MHZ.
- The
RAM is 66MHZ only, but server board needs the PC-100
or PC-133 MHZ type.
You
can check all the configuration in the user manual of server
board to
find out the proper solution of your system. 2.
CPU
-
CPU does not plug well into the basic button.
- CPU
Clock switch is set in improper position.
- The
slot 1 of the Intel Dual CPU server board has to be
plugged the processor terminator card as you use signal
CPU.
- Two
CPUs on the Intel Dual CPU server board have different
speeds and frequencies.
Any
of the above conditions will halt the system. |
| |
B)
RAID system |
| |
-
A failing SCSI device (adapter, drive, controller)
-
An improper SCSI configuration or SCSI termination jumper
setting.
-
Duplicate SCSI IDs in the same SCSI chain.
-
A missing or improper installed in or on SCSI terminator.
-
A defective SCSI terminator.
-
An improper installed cable.
-
A defective cable.
|
|
If
you have followed these directions correctly, these should
be no problem. If not, please check the problem is only
single unit or whole power. Then replace the new power
supply unit, send the defective power supply unit to your
vendor for RMA operation.
