Chapter 3 Management and Maintenance
Checking the Server Air Flow
•
Make sure there are no objects to obstruct airflow through the server.
•
Do not operate the server without drive carriers in the drive bays.
•
Use only Supermicro recommended server parts.
•
Make sure no wires or foreign objects obstruct air flow through the chassis. Pull all excess
cabling out of the airflow path or use shorter cables.
The control panel LEDs display system heat status. See “Control Panel” in Chapter 1 for
details.
Overheating
There are several possible responses if the system overheats.
•
Use the LEDs to determine the nature of the overheating condition.
•
Confirm that the chassis covers are installed properly.
•
Make sure all fans are present and operating normally.
•
Check the routing of the cables.
•
Verify that the heatsinks are installed properly.
3.4 CMOS Clear
JBT1 is used to clear CMOS (see motherboard drawing, Chapter 4). Instead of pins, this
jumper consists of contact pads to prevent accidentally clearing the contents of CMOS.
To Clear CMOS
1.
First power down the system and unplug the power cord(s).
2. Remove the cover of the chassis to access the motherboard.
3. Remove the onboard battery from the motherboard.
4. Short the CMOS pads with a metal object such as a small screwdriver for at least four
seconds.
5. Remove the screwdriver (or shorting device).
6.
Replace the cover, reconnect the power cord(s) and power on the system.
Notes:
Clearing CMOS will also clear all passwords.
Do not use the PW_ON connector to clear CMOS.
