PX-FRONT-FAN and PX-REAR-FAN
Modules
The 28 RU Platinum IP3 has two separate
PX-FRONT-FAN
modules, one at the top of the frame, and one
at the bottom (the two modules are mirror- images of each other and are not interchangeable). Each
Front Fan module contains six individual fans. There are seven large fans that exhaust heat from the rear
of the frame. The
PX-REAR-FAN
Rear Fans provide the main cooling for the entire frame (power supplies
and modules).
The 15 RU Platinum IP3 has a single PX-FRONT-FAN module that contains six individual fans. There are
four large fans on the rear of the frame that provide the main cooling for the entire frame (power
supplies and modules).
Front Fan Module
The
PX-FRONT-FAN
module is hot swappable and its main function is to cool the IP3 Video Crosspoint.
Each PX-FRONT-FAN module contains six 40 mm2 fans. The temperature of the Video Crosspoint
module is communicated to the Front Fan modules; the speed of the fans is adjusted to 25%, 50%, or
75% of their full speed based upon the temperature of the Video Crosspoint module. If the Front Fan
module detects a fan failure or loss of communication with the Resource module, the other five fans in
the array are automatically set to 75% speed. (100% speed does not affect cooling performance.)
CAUTION
: Front Fan modules are the main source of cooling for the Video Crosspoint modules. In the
event of a fan failure, ensure that you replace the fan as soon as possible to prevent overheating.
Fan failures are indicated by alarms to the Platinum IP3 Controller, and by lit LEDs beside the fans
themselves.
