12.2 PoE troubleshooting

If you are experiencing connection issues with the remote keypad when
powering the device via PoE, consider using the keypad's dedicated power
connector to supply the power to the device.
Possible causes for connection issues are:
• Low or inconsistent voltage at the power supply to the PoE switch or
PoE injector.
• Inadequate power or data cabling.
• If multiple devices are powered via PoE from the PoE switch or PoE
injector, the power allocation for the PoE devices may be too high,
either because there are too many device connected, or the total power
consumption exceeds the supported allocation. Refer to the switch or PoE
injector's documentation for more information on the PoE power allocation.
