Moxa ME51-S-SC [2/2] Dip switch setting

Moxa ME51-S-SC [2/2] Dip switch setting
6. Dip Switch Setting
Power input setting
• Power source from AC-DC
Power Adapter enabled
• Power over USB enabled
Communication setting
Dip Switch Dip Function
FDX FX at full duplex (default)
FX
HDX FX at half duplex
LFP Enable Link Fault Pass-through (default)
LFP DIS Disable Link Fault Pass-through
FDX TP at full duplex (default)
HDX TP at half duplex when TP at Force
100 TP at 100M (default)
10 TP at 10M when TP at Force
AUTO TP at auto-negotiation (default)
TP
FORCE Force TP at 10M or at half duplex
Note: You must set DIP Switch 1 to "FORCE" when
DIP Switches 2 and 3 are set to "10" and
"HDX," respectively
For ME51-S-SC, DIP Switch 5 must be set to
"HDX"
After resetting the DIP Switches, you must
reboot ME51 to activate the new settings.
7. Link Fault Pass-through
Note:
The Link Fault Pass-through (LFP) function is
enabled by DIP switch. Disable the LFP function by
setting the DIP switch to the LFP DIS position.
This media converter supports Link Fault Pass-through (LFP)
for TX/FX converter applications.
Link status on one port is propagated to the other port to
notify remote nodes. If the TP port is unplugged, the ME51
stops transmitting over the fiber port, causing the remote
fiber node link to fail. The LED will show link failure on both
the TP and fiber ports. If the fiber link fails, the ME51 restarts
auto-negotiation on the TP port, but stays in the link failure
state. This causes the remote TP node link to fail. The LED
also shows the link failure on both the TP and fiber ports.
The figures below show normal status when the link succeeds,
and the error status when TP Cable A, Fiber Cable B, or Fiber
Cable C fails to connect.
Normal status via a pair of LFPs
Status if TP Cable A is broken
Status if Fiber Cable B or C is broken
Note :
●
indicates LNK/ACT LED Lit
○
indicates LNK/ACT LED Off
Warning: The LFP (Link Fault Pass-through) function works
only when two converters working as a pair have
LFP capability. Furthermore, both LFP converters
should be supplied by the same
manufacturer/vendor. If you are using an odd
number of converters, or models that don’t support
LFP, then the LFP function will not work.
