Front Fan Module
The 1 and 2 RU Platinum VX frames have four fans that are connected directly to the main board.
The 4 RU Platinum VX frame has 2 fan modules, with 4 fans mounted on each fan.
The 8 RU Platinum VX frame has 16 fans mounted on four front fan modules.
Since the 4 and 8 RU Platinum VX frames both have redundant Crosspoint/Control modules, grouping
the fans on separate fan modules ensures the active Crosspoint/Control Module is cooled if the
redundant Crosspoint/Control Module is removed in order to be serviced.
When the frame is powered up, by default, the fans initially run at full speed, and then stabilize to
normal speed in a minute or so.
If any of the fans in the group fail, an alarm is triggered (see Fault Descriptions (see "System Fault
Descriptions" on page 137)).
CAUTION: Front Fan modules are the main source of cooling for the entire system. In the event of a fan
failure, ensure that you replace the fan as soon as possible to prevent overheating.
