SETTING THE MODE SWITCHES
 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.

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.
