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.
