Alarm Expansion Module (PX-ALARM)
The Alarm Expansion module (
PX-ALARM
) controls and monitors the Rear Fan modules and the GPI
Inputs and Power Supplies.
The PX-ALARM module reports the status of the Rear Fans (Tachometer reading), Internal and External
Power Supply Alarms, and GPI Inputs, to the IP3 Controller via the Resource Module (PX-RES), and to
LEDs and GPI Outputs on the PX-ALARM (Platinum IP3 frame rear). The PX-ALARM can control four GPI
Outputs.
The module is located to the mid-left of the 28RU frame and to the bottom left of the 15RU frame, and
is accessible from the rear of the frame. The module is hot-swappable but when unplugged from the
frame, the Front and Rear Fans speed will increase to 100%. The PX-ALARM controls the speed of the
rear fans based on power supply loading.
