Selective Advertising is a mode in which the speed and duplex for the copper and
the fiber are specifically advertised. This mode is available when DSW 5-8 are set
to OFF.


Troubleshooting Features

The McBasic 10/100 media converters include two advanced troubleshooting
features to help locate “silent failures” on the network.

Transparency

Link Fault Detection (LFD)

Transparency

Transparency is only available in PNP mode. Transparency treats the connection
between the two end devices as if there were no media converters installed. In a
typical application where two media converters are installed between two
copper-based switches, the twisted pair cables as well as the fiber cable are seen
as one entity. If a fault occurs on any segment between the two end devices, link
LEDs on the end devices will go out. This prevents any failure on the link
between the end units from going undetected.
As stated, transparency is available when McBasic 10/100 is operating in Auto
Negotiation mode:

S6 PNP (AN) must be ON

S5 (LFD), S7 (Force) and S8 (10 or 100) must be OFF
