System Components Server Front Side The front side of the server is provided to show the front exterior components of this server. The chassis is made of strong rust-resistant metal and covered with a protective ivory surfacing. II.

Chassis intrusion switches can be connected to the motherboard’s “chassis” connector to allow monitoring of the chassis side panels’ open/close status. If either one or both of the side panels are opened, the motherboard’s onboard hardware monitor can provide alerting and logging with the provided management software. AP2500 Hardware Reference Guide 13 II. System Components Chassis Panels There are two identical side panels on the chassis, one on each side. Each panel is secured by two large thumb screws on the front of the server. To open the left side of the panel (see the left view), remove the side panel screw, then pull the handle outward while pulling the panel forward. To open the right panel, the front door must be removed by pushing down on the hinge spring. Opening the side panel Front door hinge spring With the left panel removed, you should see the following components if you purchased a complete server.

System Components Chassis Circulation System The circulation system cools the hard disk drives by bringing fresh air in from the side of the server and forcing the hot air out through the back. The server’s air circulation system is comprised of two 3 inch (8 cm) fans mounted in a removable module which brings cool air in from the outside to cool the hard disk drives. Another set of two 2 1/4 inch (6 cm) cooling fans mounted on the chassis, forces the warm air out of the chassis. The two fans in each module provides redundancy in order to increase air flow as well as insure continued circulation if one fan should fail. This circulation system should ensure that the air surrounding the hard disk drives are kept below 122°F (50°C) to prevent hard disk failures. Rear Cooling Fans The system fan modules on the rear is held by two screws and four latches on the interior of the chassis. There are four screws used to secure the fan into the individual frames. The fan module’s operating status can be viewed through the ASUS ASMA software. If an individual fan fails, remove the fan and send it back to the vendor for replacement. If both fans fail, it may be that the fan control board needs replacing. If the fans do not work after replacing both of them, remove the control board and send it back to your vendor for replacement.

Components Rear Cooling Fan Control Board The rear fans are controlled and monitored by a control board. The fan control board requires power input from the power supply which allows the individual fans to obtain their power when connected to the control board. The control board also sends fan status information to the LEDs located on the front of the server and to the ASMA software. The fan control board’s cable connections are shown below.
