Table 2 describes the LED combinations of the hub “Media
Adapter” LED and the redundant fiber media adapter LEDs.
Remote Signaling
The BayStack 10BASE-FL RDN Media Adapter supports remote
signaling to indicate a far end receiver failure/remote fault
detection. Bay Networks uses a proprietary version of remote
fault signaling, because remote signaling is not specified in the
IEEE 802.3 10BASE-FL standard. Remote signaling is used to
verify the connection status of both the transmit and receive
fibers.
A Rem LED on the media adapter indicates remote signaling
status. For more information about this LED, see “LEDs” earlier
in this guide.
Table 2. LED status combinations
Hub LED Rem Rdn Meaning
Green Green Green Active link in a redundant port pair; link
status is good, and remote link is good.
Amber Green Green Standby link in a redundant pair; link status
is good, and remote link is good.
Amber Green Amber Standby link in a redundant pair is
partitioned or not ready; remote link is good,
but port is partitioned by detection of a local
fault (or possibly network management).
Amber Amber Amber Standby link in a redundant pair is
partitioned for remote fault; check Tx link.
Off Off Amber Standby link in a redundant pair has failed
connection; check Tx and Rx links.
