Cabletron Systems NBR-220, NBR-420, NBR-620 manual Setting Mode Switches

Preparing the NBR for Installation

3.2.2 Setting Mode Switches

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.

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.

!

CAUTION

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.

•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.
