1150 23-inch Fan Tray
The Tellabs 1150 23-inch Fan Tray is a compact 1RU forced air cooling module capable of moving 1600 Cubic Feet per Minute (CFM) of air flow. It is recommended that two (2) fan trays are installed per Tellabs 1150. One fan tray should be mounted above, and one below, the Tellabs 1150 with minimum 0.75- inch air space clearance.

Features and Benefits

  • The fan tray air flow discharges vertically
  • Integrated fan tray alarm contacts are used to monitor fan health
  • Test switch is easily accessible on front faceplate
  • Capable of moving 1600 CFM of air flow

Included Highlights

Status and Alarm LED indicators

The 23-inch Fan Tray has status LED indicator on the front panel lights solid green when the Fan Tray is operating normally. The Alarm LED indicator on the front panel lights solid red when the Fan Tray is in an alarm condition. The Test push-button on the front panel runs a self-test on the Fan Tray when pressed and released.

Temperature and Fan Control

The internal controller board adjusts the speed of the fans based on the ambient air temperature flowing into the fan intakes and sends an alarm signal to the Tellabs 1150 if a fan should fail.

Optimal Performance

The Fan Tray can circulate 1600 CFM of air flow. The Fan Tray air flow discharges vertically. A third Fan Tray is not necessary, when two (2) Tellabs 1150s are installed, since two (2) Fan Trays provide sufficient cooling.

Easy Installation

The Tellabs 1150 23-inch Fan Tray has a 14-pin Molex connector socket, two LED indicators, and a self-test switch on the front panel. The connector on the Fan Tray front panel is the input for –48-VDC power and the alarm output should fan fail.
