DIP switches
SSF (Single Strand Fiber) requires one
strand of fiber but two mated products.
The SFP version of the Giga-McBasic II
supports a LOW SPD dip switch
located on the front on the unit.
The Giga-McBasic II includes a Link Fault
Pass-Through (LFPT) DIP Switch, located on
the front of the unit.
Link Fault Pass-Through (LFPT) is a troubleshooting
feature that combines TX and FX LinkLoss from both the
local and remote Giga-McBasic II, TX-FX/SFP modules.
LFPT is enabled by setting the DIP Switch to ON. This
feature allows either end of the conversion to detect
a link fault occurring at the other end of the media
conversion chain.
On the Giga-McBasic II LFPT is supported
on the connector closest to the dip switch.
