Chapter 1: Overview

AT-SBx31FAN Tray

The AT-SBx31FAN Tray consists of four fans with speed control and status circuitry. It is a field replaceable assembly that is factory installed and shipped with the AT-SBx3112 Chassis.

The fan tray is initialized by the Switchblade x3112 Management Software running on the AT-SBx31CFC Fabric Control Card. The fan speed is controlled automatically and is adjusted proportional to the internal operating temperature of the switch. When the ambient temperature coming into the fan tray is approximately 20 C, the speed of the fans are their lowest. The fan speed increases to provide additional cooling as the ambient temperature rises, which allows proper operation for the line cards within the chassis.

The AT-SBx31FAN Tray features the following:

Cooling across all twelve chassis line card slots

Quad-fan design for better reliability

Software controlled, temperature speed control for noise control

Hot-swappable design
