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 1-4 are set to OFF.
Troubleshooting Features
The iMcV-LIM 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 iMcV-LIM 10/100 is operating in PNP (AN)
mode:
• S2 PNP (AN) must be ON
• S1 (LFD), S3 (Force) and S4 (10 or 100) must be OFF
