To reset the 2H252-25R processor, press and release the RESET button. The 2H252-25R goes through a reset process for approximately 60 seconds. Additional downtime may result as the device reenters the network.

NOTE: It is not recommended to press the RESET button while the device is already in reset mode. If so, the device will enter an extended diagnostic procedure, which is unnecessary for normal operation. This extended diagnostic procedure takes much longer than a minute.
