The Token Ring Board Status Screen

IRM3 User’s Guide

Page 4-31

Changing Ring Port Status

The Ring Port Status option displays only when a Token Ring board with
externally accessible ring ports is installed in the MMAC. The Ring Port
Status option enables you to turn the Ring In and Ring Out ports on or off.
Depending on the type of board you have installed, the phantom current
and media type options may also display.

1. Use the arrow keys to highlight the RI or RO options for the Status

field.

2. Press RETURN to toggle between turning the port On or Off.

3. If the board has a phantom current setting, use the arrow keys to

highlight the RI or RO options for the Phantom field.

4. Press RETURN to toggle between turning the signal On or Off.

5. If the board has a media type setting, use the arrow keys to highlight

the RI or RO options for the Media field.

6. Press RETURN to toggle between the STP and FIB settings.

7. Use the arrow keys to highlight the SAVE command and press

RETURN. The message “Modified screen Information Has Been
Saved!” appears on the screen.

Changing FNB Status/Bypass Status

To change the FNB Status or Bypass Status for a board, perform the
following steps:

1. From the Device/Board/Port Counters screen, select the Token Ring

board that you want to configure. Refer to Section 4.8.1 for
information on selecting a board.

2. From the Token Ring Board Status screen, use the arrow keys to

highlight the LEFT or RIGHT option if you want to configure the FNB
multiplexer.

3. To change the board’s bypass status, highlight the BYPASS option.

4. If you selected the LEFT or RIGHT option, press RETURN to toggle

between ATTACHED and DETACHED. If you selected the BYPASS
option, press RETURN to toggle between BYPASSED and
INSERTED.
