1RU Fan Tray Unit
The Tellabs 1000 1RU Fan Tray is a compact forced air cooling module. You can control the speed of the fans and the fan activation and deactivation temperatures. The fan tray rack-mounts directly under an Tellabs 1000 CBA to distribute cooling air through the plug-in cards to dissipate heat. The 1U Fan Tray moves air at approximately 400 cubic feet per minute (CFM). The thermostat activates the fans at 35º C (96º F) and deactivates them at 30º C (85º F). You can set the fan activation and deactivation temperatures on the fan tray control board. The maximum power draw for the 1U Fan Tray is pproximately 30W at 48 V DC. The 1U Fan Tray can activate the Fan Failure (minor alarm) in the Craft Interface.
