Fan Tray Module

The device provides two Fan Tray modules, located on either side of the chassis. Each module contains five integrated fans which cool the device's internal components. The Fan Tray module located on the left side of the chassis draws air in from the outside through its' perforated grill. The incoming air passes through the chassis, cooling each module, and then the Fan Tray module located on the right side of the chassis expels the air through its perforated vents.

Airflow Directions through Chassis

Fan Tray Modules (1 and 2)

When installing the chassis, make sure there is sufficient right- and left-side clearance for airflow into and out of the chassis.

For replacing Fan Tray modules, see Replacing the Fan Tray Modules .

Each Fan Tray module provides a STATUS LED on its front panel, which indicates the operating status of the Fan Tray module and its corresponding (closest) Power Supply module. In other words, Fan Tray module #1 corresponds to Power Supply module #2, and Fan Tray module #2 corresponds to Power Supply module #1.

Description

Green

On

Fan Tray module and corresponding Power Supply module are operating normally.

Red

On

Indicates one or both of the following:

■ Fan Tray module failure.
■ Power failure due to any of the following:
✔ Failure in corresponding Power Supply module.
✔ Failure in power source (e.g., disconnected power cord).
✔ Corresponding Power Supply module not installed in the chassis.

-

Off

Indicates one or both of the following:

■ No power received by the chassis. This indicates a problem related to both Power Supply modules. This could be due to a failure in both Power Supply modules or a failure in the power source (e.g., disconnected power cords) to which the modules are connected.
■ Fan Tray module not receiving power due to a failure in the module or module not inserted correctly.
