System Cooling
There are three main cooling areas in the CG2100 server as illustrated in Figure 9.
• CPU2 and memory (blue in Figure 9) with two redundant , hot-swappable 80mm fans
These fans facilitate the air flow through the front bezel, over the server board,
CPU2, and out through the rear of the chassis.
• CPU1 and memory (green in Figure 9) with two redundant, hot-swappable 80mm fans
These fans facilitate the air flow through the front bezel, over the server board,
CPU1, and out through the rear of the chassis.
• PCI riser assembly (red in Figure 9) with two redundant, hot-swappable 60mm fans
These fans facilitate air flow through the fans, over the server board, any PCI add-
in cards in the riser assembly, and out through the rear of the chassis.
There is also another cooling area with two fans in redundant power supply
configurations for the power supply subsystem. These fan(s) also cool the hard disk
drives. The air flow is adequate even with a single power supply module installed as
long as the filler panel is installed in the unused power supply slot.
Figure 9. CG2100 Server Cooling Areas
The three-zone cooling subsystem is sized to provide cooling for:
• Up to two server board processors
• Up to 96 GB of DDR3 memory
• Up to six SAS/SATA hard disk drives
• Up to five PCI add-in cards consuming a maximum of 25W for each full-height PCI-
X/PCIe add-in card and 10W for each low-profile PCIe add-in card.
The cooling subsystem meets acoustic and thermal requirements at the lower fan speed
settings. At the higher fan speed settings, thermal requirements are met for the
maximum ambient temperatures, but acoustic requirements are not met.
