Cabletron Systems NBR-420 사용자 설명서

Figure 3-2 shows the location and factory default settings of the mode 
switches. Check these switches to ensure that they are in the correct 
position for normal NBR operation.

Switch definitions are as follows:

•

Switch 1 - Cabletron Systems use only.

•

Switch 2 - Cabletron Systems use only.

•

Switch 3 - Cabletron Systems use only.

•

Switch 4 - Cabletron Systems use only.

•

Switch 5 - Baud Rate Default. Allows you to set the Console port baud 
rate. The OFF position sets the baud rate to 9600. The ON position 
sets the baud rate to 2400. The default position is OFF.

•

Switch 6 - Forced Download. Changing the state of this switch (i.e., 
moving the switch from one position to another) forces the NBR to 
download an image file from the station acting as the TFTP server.

Never adjust switch settings while the NBR has power applied 
to it. Not only is this dangerous, but the change in position 
activates the switch function and after you reinstall or power 
cycle the NBR it will initiate the request.

Do not change the state of Switch 6 unless the following 
conditions exist:

You have a station acting as a BOOTP server, and a TFTP 
server that contains the NBR image file. The BOOTP server 
and the TFTP server could be different servers.

You intend to set up a station to act as a BOOTP server for the 
NBR.
