Troubleshooting Guide
4.1 Overview
This chapter describes the troubleshooting methods for the power system.
Figure 4-1 shows the alarm check method for PMU02B. For details about PMU menus, see
the TP48200A-D17B3 Quick Installation Guide (V100R001_01). After alarms are cleared, the
ALM LED turns off and the buzzer stops. You can query the alarms in history alarm
information.
Issue 03 (2013-05-06)
After you rectify a fault, the corresponding alarm in the PMU is automatically cleared and is
recorded as a history alarm.
After you replace the PMU, you need to set parameters again. For details, see the TP48200A-D17B3
Quick Installation Guide (V100R001_01).
The PMU and PSU are hot-swappable.
Take anti-static measures when replacing the signal transfer board. For example, wear an ESD wrist
strap.
