Speaker / Circulation
Air Circulation System
The server’s air circulation system is comprised of one 3 inch (8 cm) fan mounted on the inside rear of the chassis and another one mounted on the front of the chassis, as well as the power supply itself. The air circulation system cools the internal system by bringing fresh air in from the back and forcing the hot air out through the front. It is important to keep the air surrounding the hard disk drives below 122˚F (50˚C) to prevent hard disk failures.
IMPORTANT: The chassis panels must be installed for proper air flow.
Fan Replacement
The two individual fans are secured by plastic housings. The fan housings can be removed by pressing in the clip and sliding the housing upward.

IMPORTANT: When replacing the fans, be sure that both fans rotate in the same direction. Use the manufacturer’s sticker on one side of the fan as a reference. The air should flow from the rear of the chassis to the front of the chassis.
System Speaker
This server has a standard speaker for error notifications and other alerts. For computer audio capability, an audio card and external speakers are nec- essary. The standard system speaker mounts in the chassis as shown here. To remove the speaker, press the metal clip (or pry from front) with a screwdriver and lift the speaker upward.
