Power Issues

This section provides troubleshooting information about power issues.
Power Shortage of Peripheral Equipment
If the peripheral equipment is suffering from a power shortage and the Cisco Edge 340 Series device is
powered by Power Over Ethernet (PoE), verify if the device is powered by PoE 802.3AF. If yes, change
it to the 802.3AT mode, because the power supported by 802.3AT is more stable than the power
supported by 802.3AF.
USB Ports on the Rear Panel Not Working
If only the two USB ports on the front panel are working, and the USB ports on the rear panel have no
power, verify if the Cisco Edge 340 Series device is powered by PoE. To enable the USB ports on the
rear panel, use external power supply.
OL-29491-01
Verify if the encryption and authentication mechanism between the third-party device and Cisco
Edge 340 Series are matched.
Verify if the network card in the third-party device supports 5G. The network cannot be connected
unless this item is matched.
