Hi,
we are using VVX 500 Phones at Cisco 3850 Switches and the switch then are reservate 15.4 watt at the port. That are normaly to many, because the Phone only need max. 5.0 Watt.
If i configure a fixed Power from 7 Watt to the Switchport, the Phone is not working(Starting).
Is there any explanation why it doesn't work at 7 watts?
regards,
Oliver

Hi @OliverR.,
as you can see from following document, VVX500 and VVX600 advertise as Class 4, on conformance with IEEE802.at. Therefore I think, maximum power Range used by the phone is 12,95–25,50 W.

Hello @Oliver.R,
welcome back to the Polycom Community.

This ensures the questions having to be asked are limited and any new or follow up post contains the right amount of details to ensure any voluntary participant within the community does not spend additional time chasing basic information.
As a reminder the basic information asked for:
- Provide the exact Software Version of your Phone
- Provide the Phone Model
- Provide the Call Platform (aka openSIP, Skype for Business, Lync)
- If applicable provide a backup of the phone in question
UC Software 4.0.0 or later via the Web Interface Utilities > Phone Backup & Restore > Phone Backup > Phone Backup
- If possible provide a Log and either attach them or use the Code Tag.Consult the Troubleshooting Section found within the FAQ if applicable
- If possible provide the MAC Address or Serial of the device
- Provide details if the issue is a day 1 issue or only happened after an upgrade or any other relevant details
Whilst providing the answers to some of the above may not directly impact any possible answer the community can provide, it does enable Polycom to have an overview of the current software used and other details and allows us to look up a potential support partners if an issue needs to come into support.
