Bay Technical Associates Fiber Media Adapter manual Remote Signaling

Table 2 describes the LED combinations of the hub “Media Adapter” LED and the redundant fiber media adapter LEDs.

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.

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.
