COM Port and FDDI Front Panel Displays
Note that, like the Module menu, neither the COM port nor the FDDI front panel
displays are affected by changes in the Application Display. The COM port
display always shows each port’s administrative status (ON or OFF), both in the
text display and in the color code (green = ON, blue = OFF); the FDDI front panel
display changes based on the port display form selected via the FDDI menu, as
illustrated below.

successful. Ports which are not connected and which have not been disabled
by management will display this status.
• ACT (active) — the port has been enabled by management and has
successfully established a link.
• SBY (standby) — the port has a physical link, but the SMT Connection Policy
is prohibiting a logical connection to the ring because the attempted
connection is illegal. FDDI protocol always forbids connecting two Master
ports; all other connections are theoretically legal, although some are not
TIP
Note that, although the COM port menu does not change based on the Application
Display mode selected, the UPS option will only appear for COM ports which have been
configured for a UPS. See Configuring COM Ports,
page 2-36 , for more information.
