Cabletron Systems EMM-E6 - Manual (Page 47)

Managing the Hub 2-31
Using the EMM-E6 Hub View
mode. When configured to operate on channels B or C, the TPXMIM provides its
own repeating; when operating on Channel A, its ports depend on the EMM-E6
for repeater functionality. All TPXMIM ports default to channel B when first
installed.
To configure FNB connectivity for the board as a whole:
1. Click mouse button 3 in the appropriate area to display the Network menu
(refer to
Figure 2-5 , page 2-7 ). Be sure to display the Network menu from the
TPXMIM you wish to change, as this menu option applies only to the TPXMIM
from which it was accessed.
2. Drag down to Change Channel, and right to select Channel A, Channel B,
Channel C, Standalone, or Restore B/C State, as appropriate:
a. Use the Channel A, Channel B, or Channel C options to switch the
TPXMIM’s channel to A, B, or C, as desired; keep in mind that each of
these board-level settings will override any individual port-level settings.
b. Use the Standalone option to switch all ports currently configured to use
channels B or C to a stand-alone mode; this stand-alone mode is identical
to the stand-alone mode for the other RIC MIMs, and has similar
implications. However, note that any ports which are configured to
operate on Channel A will remain connected to Channel A, and will not
switch to stand-alone.
c. Use the Restore B/C State option to switch stand-alone ports back to the
configuration status they had before they were switched to stand-alone:
ports that were on Channel B will return to Channel B; ports that were on
Channel C will return to Channel C. Again, this option does not affect any
ports that were configured for Channel A; those will remain connected to
Channel A. This option should only be used when the board is in a
stand-alone state; if you select it when the board is assigned to a channel,
the set will fail and an error message will be displayed.
To configure FNB connectivity for an individual port:
1. Click mouse button 3 on the appropriate Port Status or Port Index box to open
the Port menu.
2. Drag down to Change Channel, then right to select Channel A, Channel B,
or Channel C, as desired. Note that individual ports cannot be placed in
stand-alone mode via this menu.
NOTE
Be sure to refer to the Release Notes that were shipped with your EMM-E6 firmware for
more information about the implications of operating your TPXMIM in a stand-alone
mode.
