1.5.5
Air Inlets
Air inlets are located along the lower, upper right and middle of the front panel. The air inlets
are designed to provide maximum air flow. The air flow is critical for maintaining the proper
temperature range. Fans in the front unit draw air in through the front inlets.
CAUTION:
Do not obstruct the airflow when mounting the device on the rack. Severe equipment
damage can result when the device cannot properly exhaust the airflow.
1.5.6
Cooling Fans
The NSG 9000 platform uses four fans to control the temperature during operation. The fans
located in the front of the device, use air from the front and exhaust it to the rear of the
device. Each fan has a speed control and the CPU manages their speed to increase Mean
time Between Failures and to lower the noise level.
All four fans are mounted on the back side of the front panel to allow a quick and easy hot
swap in case of a fan failure. For further information, refer to
1.5.6 Cooling Fans
on page 13.
