Problem Description
The customer needs POE power for the competitor's IP telephony. After connecting to our switch, it was found that it could not be activated. When using POE in Model B mode, the phone works normally.
Process Analysis
After the investigation, it was found that the IP telephony model only supports power supply from model B, and our switch products only support switchover power supply mode with the 802.3BT products.
The specific model suffix HPWR switch supports power supply from model B.
Use the command.
poe mode { signal | spare }
signal is model A
spare is model B
Solution
Use the HPWR model switch.
