Note:
1) To ensure the best stability, please purchase UL certified CAT5E Ethernet cables and recommended PoE
switch. The maximum length of each Ethernet cable is 50 meters. Contact the agents or Yealink technical
suppor to get the recommended PoE switch models.
2) When the PoE switch cannot meet the power supply requirements of the RCH40 (overload), the PoE-
Max indicator of the RCH40 will light up. In order to stabilize the power supply of the devices connected to
the RCH40, the ports corresponding to the RCH40 that exceed the power supply requirements will be reset.
After resetting, if RCH40 detects that the port is still overloaded, it will continue to reset the port until the port
returns to normal or is unplugged.
