Optical Bypass — Enabled (green):

If you are using a bypass switch, the Optical Bypass—Enabled LED

lights only when the switch is causing the FDDI ring to bypass the

router. (The router will be bypassed when it is booting and when the

FDDI circuit is disabled.) That is, the Optical Bypass LED is not lit

when the FDDI circuit is enabled.

If you are not using a bypass switch, the Optical Bypass—Enabled

LED is always lit, regardless of the state of communication between

the router and the FDDI ring.
