B.3 SETTING THE MODE SWITCHES
Figure B-2 shows the location of the mode switches and the switch settings for normal operation.
These switches are set at the factory and rarely need to be changed.
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.
NOTE
After changing the position of switch 6, DO NOT reapply power to the chassis until there
is a station on the network acting as a BootP server, which contains the downloadable
firmware image file.
