•Switch 6 – Forced BootP. The BootP server references the location of
a station acting as a Trivial File Transfer Protocol (TFTP) server
containing the 2H22-08R image file.
When the position of Switch 6 is changed and the power is cycled to
the 2H22-08R, the device requests the image file location from the
BootP server and uses TFTP to download the image from the TFTP
server. If one of these requirements is not met, the 2H22-08R will
continue to request either the BootP server or the TFTP server until the
RESET button on the 2H22-08R is pressed. Once the RESET button
is pressed, the 2H22-08R resets after one minute and loads the image
stored in FLASH memory.
•Switch 7 – Clear NVRAM. Changing the position of this switch resets
NVRAM on either the next power-up or the next operation of the front
panel RESET button. All user-entered parameters, such as the IP
address, device names, etc., are reset to the factory default settings.
Once the 2H22-08R resets, you can either use the factory default
settings or reenter your own parameters.
•Switch 8 – Reset Password/Community Strings. Changing the
position of this switch clears user-entered passwords stored in
NVRAM, and restores the factory default passwords on either the next
power-up or the next operation of the front panel RESET button. Once
the 2H22-08R resets, you can either use the factory default settings or
reenter your own passwords.
NOTE Do NOT attempt a Forced BootP unless a BootP server has
been configured for the 2H22-08R.
NOTE Do not change the position of switch 8 unless it is necessary to
reset the 2H22-08R super-user configured passwords to their
factory default settings.
