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 control buttons and
status indicators. These wires have been bundled together in a ribbon cable 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

The 1012C-MRF server employs two sets of 4-cm counter-rotating fans to provide
cooling. Each fan unit is made up of two fans joined back-to-back, which rotate in
opposite directions. This counter-rotating action generates exceptional airflow and
works to dampen vibration levels. The fans can adjust their speed according to
the heat level sensed in the system, which results in more efficient and quieter fan
operation. Fan speed is controlled by a setting in BIOS (see Chapter 7). Each fan
in a set has its own separate tachometer.
Note: It is very important that the chassis top cover is properly installed for the
airflow to circulate properly through the chassis and cool the components.
