Note:
Check these thresholds on the NIC.
A major alarm generated for a power supply voltage implies that the TMS deriving power from that
supply is not functioning correctly. An over-voltage condition can damage the TMS card.
The following modules can be affected:
• power supply
• NIC
The power supply voltage generate alarms due to the following conditions:
1. power supply not calibrated
2. faulty A/D on power supply
3. hardware fault corrupting A/D Bus
4. incorrect conversion for temperature (cardtypes.cfg)
5. short exists on the power supply or TMS backplane
Troubleshooting
Use the NCD chassisinfo command to retrieve the power supply temperature, voltage, and current.
Then determine your course of action. A faulty A/D reports unusually high or low values.
Power Supply Current
Each power supply for a VRC chassis has an A/D attached to the current outputs from the supply.
The controlling NIC monitors these power supply currents. A major alarm generates if the current is
95 percent or greater than the maximum rating and indicates the current is not correct.
The following modules can be affected:
• power supply
• NIC
The power supply current generates alarms due to the following conditions:
1. faulty A/D on power supply
2. hardware fault corrupting current readings from A/D
3. incorrect conversion for temperature (cardtypes.cfg)
4. short exists on the power supply, TMS, NIC, or backplane
Troubleshooting
Use the NCD chassisinfo command to retrieve the power supply temperature, voltage, and current.
Then determine your course of action. A faulty A/D reports unusually high or low values.
