Table 1: Alarm Details
Equipment Brownout: A brownout condition has been detected on a UFM that is installed in a BTI7800 Series chassis powered by a DC power entry module (PEM).
Caution: Continued operation might cause equipment damage.
UFM modules (see table below)
Note: For UFM3 and UFM4 modules, this alarm results in an automatic cold reload of the UFM.
The supply voltage to a UFM is lower than the minimum normal voltage threshold for the module, but not lower than the power-off threshold.

Clearing an EqptBrownout Alarm
Follow all applicable safety requirements as described in the BTI7800 Series Hardware Overview and Installation Guide.
- Retrieve environment information to view voltage data
for the UFM and each PEM installed in the chassis:
show environment voltage
- Check for and clear alarms raised against the PEMs, and ensure that they are properly seated and connected to power.
- Check for alarms on the UFM.
If the alarm has cleared, you have completed this procedure.
If the alarm does not clear, contact your next level of support.
