Problem Description

On-site feedback indicates that after replacing the 3600 switch with the 5130 switch, some phone sets restart after calls, and alarms are also recorded in the logs.

Process Analysis

1. Only the switch port supplies power. The switch is configured with non-standard POE monitoring and forced power supply, but the issue persists

2. Only external power supply is used. The switch POE power supply function is turned off. After plugging in the phone sets built-in power adapter, it works normally

3. Check the device power supply status. The device has 1585.3(W) remaining. If power insufficiency is suspected, the probability is low

4. On-site, the switch and phone set are connected via a distribution frame. The patch cord from the switch to the distribution frame has been replaced. Fluke test passed

5. Product line analysis and diagnosis information reveals overcurrent power-off records on ports 4, 27, and 41, consistent with the on-site feedback phenomenon (ports 4, 27, and 41 of 5130-1 connected to IP phone sets experiencing repeated reboots).

The reason for POE flapping: The customer's phone set is a Class1 terminal, which matches the switch classification result (as highlighted in the diagnostic information below). According to the IEEE standard, the maximum power supply for Class1 is 4W. If the terminal phone's power consumption exceeds 4W, it will trigger an overcurrent power-off on the switch side. After power-off, the switch will re-detect the classification and restore power, resulting in POE flapping at the customer's site.
