Not sure on the exact model of switch involved but the firmware is Comware 7.1.045 Release 3113P05.
There is plenty power budget for the device and we have allowed the device to draw as much as it needs.
Logs on the switch shows many PVID mismatches -
LLDP/5/LLDP_PVID_INCONSISTENT: PVID mismatch discovered on GigabitEthernet x/x/x
F-U-5130 LLDP/5/LLDP_PVID_INCONSISTENT: PVID mismatch discovered on GigabitEthernet x/x/x (PVID x) with <ApName> (PVID 0)
