External Power Supply frames can be connected to the Platinum IP3 frame via DC power cables. The DC
power cables are connected to the Power Adapter boards. The Alarm and I2C signals from the External
Power Supplies are routed through the BackPlane/MI to the
PX-ALARM-DATA
board.
Status is reported for each of the Power Supplies, classified by zone.
In case of a 28RU frame:
PSU 1/2/3/4/5/6/7/8 in zones 1-4 refer to the power supplies in the frame
PSU 9/10/11/12/13/14/15/16 in zones 1-4 refer to external power supplies
PSU 5/6/7/8/13/14/15/16 will show as N/A (these are for 28 RU frames only)
In case of a 15 RU frame:
PSU 1/2/3/4 in zones 1/2 refer to the power supplies in the frame
PSU 9/10/11/12 in zones 1/2 refer to external power supplies
PSU 5/6/7/8/13/14/15/16 will show as N/A (these are for 28 RU frames only)
Each power supply provides a power supply present signal and three critical alarms: +24V, +5V, and FAN
Failure. All three alarms are critical to power supply and frame operation. If any of these alarms are
asserted:
The Platinum IP3 Controller is notified via the Resource card
The
PS ALM
LED on the PX-ALARM is illuminated red
The dedicated
Power Supply Alarm
GPI Output is asserted/triggered.
If no alarm conditions exist, the
PS ALM
LED is not illuminated and GPI Output is not asserted.
