settings for normal operation.
Figure C-1 6H122-08 Mode Switch Location/Component Layout
Switch definitions and positions are as follows:
• Switches 1 through 4 – For Cabletron Systems use only.
• Switch 5 – COM Port Autobaud. The default (OFF) position enables
Autobaud sensing on the COM port for Local Management sessions.
Changing the switch to the ON position disables Autobaud sensing and
sets the COM port to 9600 baud for Local Management sessions.
• Switch 6 – Forced BootP. Changing the position of this switch (i.e.,
moving the switch from one position to the other) clears download
information from NVRAM and forces the 6H122-08 to download a
new image file from a BootP server after power to the chassis is
restored.
NOTE
After changing the position of switch 6, DO NOT reapply power
to the chassis until there is a station acting as a BootP server,
which contains the image file.
