Fan
Assembly
A fan assembly is located in the front panel of an FR6822+ frame (see Figure 1-4). The fan
assembly draws in air from the front of the unit, and expels it through the back.
Figure 1-4 Fan Assembly (Back View of Front Panel)
All fans are equipped with RPM monitoring circuitry. Either the standard 6800+RESC
resource module or the 6800+ETH Ethernet resource module (described in 6800+ETH
Resource Module on page 5) decodes and monitors these signal to determine fan health.
Local and remote alarms report undesirable conditions that may arise.

Low fan-noise emissions
Frame ID
