After an 802.3at AP in V200R008C10 Is Connected to a Switch in V200R001, V200R002, or V200R003, the AP Works in 802.3af Mode. How Can I Enable the AP to Work in 802.3at Mode?
If the switch version is V200R001 or V200R003, install a patch on the switch or upgrade the switch to a later version. If the switch version is V200R002, upgrade the switch to V200R003 and then install a patch, or upgrade the switch to a later version.
For more information about switch versions, contact technical support personnel.
