Figure 1-3 on page 7 shows a general block diagram of the ISS C1104-GP6 serverboard's
processor and I/O chipset. Note that while the chipset is capable of controlling up to 10 drives, the
ISS C1104-GP6 chassis supports only four SATA hard drives.
The 1U server chassis has a cooling design that includes six 8-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.
