2.4.2 LANVIEW LEDs

Front-panel LANVIEW LEDs together with the LNK LED on the TPIM
installed in the TRBMIM-T provide an at-a-glance means of determining
the operational status of the TRBMIM-T and the Token Ring network.
LEDs convey information about the following system conditions and
events:

•

Normal and abnormal operating conditions

•

Ring speeds for both bridge interfaces

•

Left- and right-wrap conditions for FNB connection

•

Insertion or non-insertion of the TRBMIM-T in the FNB ring

•

Insertion or non-insertion of a device into the Station port

•

Presence or absence of frame traffic though the Station port
