Fan Unit 1-1

Technical Description

Fan Unit

1.0 GENERAL

This Technical Description describes fan units used in the VCO/4K system. The fan unit draws

hot air from inside the VCO/4K and discharges it through the rear of the VCO/4K enclosure.

The fan unit has an alarm indicator (LED) that illuminates when any of the four cooling fans

has failed.

Power is provided to the fan unit from the power backplane. The fan unit is powered

automatically when one or both Power Supply Modules is powered on.

The fan unit consists of an aluminum tray that holds the following components:

•

Eight 12Vdc cooling fans

•

Three controller cards

•

One temperature-sensitive thermal link (fuse)

•

One LED indicator
