4. Questions and Answers

Q1. The system (Server, RAID etc.) does not work, neither does the PS.
A1:
a) ATX or AT?!: The power supply with the ATX form factor is supposed to connect with the motherboard 20-
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. Also make sure the on/off push bottom or switch is on
b) Minimum load: Check the specification of power supply. Does it need the minimum load for the system? If
the answer is `Yes!", then, do not test "ON/OFF" of the system, but only test it with the power supply & on the
motherboard.
c) Short Current Protection: The peripherals of the power supply have the short conditions, and the power
supply is set on the off status.
Q2: The power supply works normally, but the monitor does not receive any signals.
A2:
a) The VGA card is too old to support the motherboard.(without sufficient memory)
b) There are some conflicts with configuration. Check the configuration. Check Q7.
Q3: Why the system restarts with the starting procedure?
A3: One of O.C.P, O.V.P. or O.P.P, occurs as the power supply works.
*O.C.P.(Over Current Protection)O.V.P.(Over Voltage Protection)O.P.P.(Over Power Protection)
For example: The +12V of PS offers maximum 9 amps. The system is installed with 4 pieces of SCSI hard
disks (per unit needs 2.5 peak amps). Therefore, a system with a total output amps of +12V point will
need 10 peak amps for the system to start to run normally. If the power is insufficient, then, the system
will restart, when the PS executes the auto recovery.
Q4: The WOL (Wake On Lane) doesn't work!
A4:
a) The +5VSB of power supply could not offer enough current to the system.
b) The BIOS or jumper (PWR Up On Modem ACT) on motherboard is disabled.
Q5: There are two types of connectors on INTEL motherboard-- 24-pin and 20-pin. Are they compatible?
A5: They are different pin assignments. Please do not plug 20-pin connector into a 24-pin motherboard.
Q6: The system does not work after the chassis has been opened.
A6: The server board supports chassis intrusion monitoring. The server board recognizes an open switch when
the chassis is open. If the chassis' intrusion-detection jumper is disabled, the switch is bypassed, and the BMC
does not monitor even if the chassis has been opened.
Q7: The system does not work after adding a new SCSI hard disk or replacing a VGA with a new one.
A7: check the following configurations:
A) On the Server system:
Check following Setup Utility/ Configurations on the serverboard:
1. Configuring: Conflicts in the configuration occur if:
