4.4 USING THE RESET BUTTON
The RESET button, located to the left of the COM port on the 2H22-08R,
(refer to Figure 4-3) resets the 2H22-08R processor without affecting the
NVRAM.
Figure 4-3 RESET Button
To reset the 2H22-08R processor, press and release the RESET button.
The device processor goes through a reset process of approximately 20
seconds. Additional downtime may be added as the 2H22-08R reenters
the network.
NOTE
The RESET button may be used in conjunction with Mode
Switch 7 (Clear NVRAM), described in Appendix C, to clear
user-entered parameters such as IP addresses and
Community Names and to replace them with the 2H22-08R
default settings. It is only necessary to use this method of
clearing NVRAM when it is not possible to access Local
Management.
Clearing NVRAM may also be performed via Local
Management. Section 5.7.11, Clearing NVRAM, describes how
to perform this procedure.
!
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.
