The RESET button shown in Figure 4-2 resets and re-initializes the 2H252-25R.
Figure 4-2 RESET Button
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.
CAUTION: Pressing the RESET button resets the device, and all current switching
being performed by the device is halted. A network downtime of up to two minutes will
result from this action.
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.
