Bridging Functionality In Bridge/Management Mode
The TRBMIM-T performs the same source-route bridging functions
when in the Bridge/Management operational mode as it does when it is in
the Bridge-Only operational mode. The TRBMIM-T must simultaneously
perform both ring-management functions and bridging functions when in
the Bridge/Management mode. Consequently, its bridging performance
(data-transmission rate) does not equal the rate achieved when it is in the
Bridge-Only mode.
For optimal bridging performance as required by your
NOTE
bridged-ring installation, operation of the TRBMIM-T in the
Bridge-Only mode is recommended.

1.4.3 Monitoring And Troubleshooting Systems

LANVIEW LEDs, located on the TRBMIM-T front panel, provide an
at-a-glance method of monitoring the module's operational status. LEDs
indicate, for example, whether the module is operating correctly and the
ring operating speed.
