6: Basic Troubleshooting and Chassis Service
Unpacking
Replacement components are usually shipped in antistatic packaging to avoid static damage.
When unpacking an upgrade or replacement component, make sure the person handling it is static
protected.
Control Panel
The control panel (located on the front of the chassis) must be connected to the JF1 connector on
the serverboard to provide you with system status indications. A ribbon cable has bundled these
wires together to simplify the connection. Connect the cable from JF1 on the serverboard to the
Control Panel PCB (printed circuit board). Make sure the red wire plugs into pin 1 on both
connectors. Pull all excess cabling out of the airflow path. The LEDs inform you of system status.
See Chapter 3 for details on the LEDs and the control panel buttons. Details on JF1 can be found
in Chapter 5.
System Fans
Six 8-cm hot-swap fans provide the cooling for the system. It is very important that the chassis top
cover is properly installed and making a good seal in order for the cooling air to circulate properly
through the chassis and cool the components. See Figure 6-2.
System Fan Failure
Fan speed is controlled by system temperature via a BIOS setting. If a fan fails, the remaining fans
will ramp up to full speed and the overheat/fan fail LED on the control panel will turn on and flash.
See the section
“Overheat/Fan Fail” on page 23
for additional information on the warning LED.
Replace any failed fan as soon as possible with the same type and model (the system can continue
to run with a failed fan). Note that you may need to remove the top chassis cover while the system
is running to accurately determine which of the fans has failed.
Note:
If the installation position of the server precludes identification of the failed fan, move the
unit to a static-free work surface and reconnect power to identify the non-working fan. Use of a
flashlight may be necessary depending on ambient light levels and system positioning.
