**WARNING**
Enable FiberAlert on one side of a media conversion only. Enabling it on both
sides would keep both transmitters off indefinitely.
Using FiberAlert and LinkLoss
Modules ship from the factory with troubleshooting features disabled. Refer to the
help file to enable/disable this feature.
Pulsing FiberAlert
Pulsing FiberAlert
minimizes the problems associated with the loss of one
strand of fiber. If a strand is unavailable, the IMC Networks device at the
receiver end notes the loss of link. The device will stop transmitting data and
start sending link pulses. Until a valid link is received, the fiber link LED will
be OFF on the device on the receiver side of the fiber strand with the fault
while the fiber Link LED on the other unit will blink.
Pulsing FiberAlert
notifies a local site administrator of a fault, allowing quick determination of
where a cable fault resides.
NOTE
Pulsing FiberAlert can be enabled on BOTH sides of a conversion.
Auto Negotiation on PSE-McBasic
PSE-McBasic modules include the feature Auto Negotiation. When Auto Negotiation
is enabled, the module negotiates as a 100 Mbps full-duplex device. If the
connected device can operate at 100 Mbps full-duplex, a link is established. Auto
Negotiation (DIP Switch #1) is enabled by default.
If the twisted pair port on the other device does not have the ability to Auto
Negotiate or if the 100 Mbps half-duplex connection is desired, then Auto
Negotiation must be disabled. Half- and full-duplex settings must be set manually
and match on does devices.
