Cabletron Systems 2E43-51 User Manual

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. Do NOT attempt a Forced BootP unless a 
BootP server has been configured for the 2E43-51. The BootP server 
references the location of a station acting as a Trivial File Transfer 
Protocol (TFTP) server containing the 2E43-51 image file. When the 
position of Switch 6 is changed and the power is cycled to the 
2E43-51, 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 2E43-51 will continue to 
request either the BootP server or the TFTP server until the RESET 
button on the 2E43-51 is pressed. Once the RESET button is pressed, 
the 2E43-51 will reset after one minute and load the image stored in 
FLASH memory.
