Figure B-1 Module 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 SmartSwitch

to download a new image file from a BootP server after power to the chassis is restored.

• After changing the position of switch 6 and restarting the module, the SmartSwitch requests a

new image download until they either receive a new image or the RESET button on the front

panel is pressed. When the RESET button is pressed, the SmartSwitch continues trying to

contact a BootP server, but will time out in approximately one minute. If the module times out,

the image is downloaded from its FLASH memory.

• Switch 7 – Clear NVRAM. Changing the position of this switch resets NVRAM on the next

power up. ALL user entered parameters, such as IP addresses, subnet masks, SNMP traps, and

switching functions are restored to their factory default settings.

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.
