system overheat/fan-fail/ UID LED. A main power button and a system reset button are also
included.
The C1104-GP2/C1110-GP2 server chassis is an ATX form factor chassis designed to be used in
a 1U rackmount configuration. The serverboard's I/O backplane supports up to three standard size
(double-width) and one half-height PCIe cards which can offer optional computing solutions. A
15-pin VGA port, two USB 3.0 ports, Gigabit LAN ports and a dedicated RJ-45 IPMI LAN port
are also supported.
Important: Check with your SGI sales or service representative prior to using any PCIe device
not sourced from the SGI factory or documented by SGI as a supported option.
Figure 1-2 on page 7 shows a general block diagram of the C1104-GP2/C1110-GP2 server's
processor and I/O chipset.
The 1U server chassis has a cooling design that includes ten internal 4-cm counter-rotating Pulse
Width Modulated (PWM) system cooling fans located in the chassis. An air shroud channels the
airflow from the system fans to efficiently cool the processor and PCIe areas of the system. Each
power supply module also includes an internal cooling fan. All chassis and power supply fans
operate continuously.
