IMC Networks iMcV-FiberLinX-II, Руководство по эксплуатации

Страница: 15 / 60

TX LinkLoss
Remote Side (or both) Twisted Pair Fiber
FX LinkLoss Host Side (or both) Fiber Twisted Pair
** WARNING **
Do not enable FiberAlert on both modules when using iMcV-FiberLinX-II in pairs.
This will cause them to lock up when a fault occurs on the fiber. Only enable
FiberAlert on the remote module.
Link Fault Pass-Through
Link Fault Pass-Through (LFPT) is a troubleshooting feature that combines TX and FX
LinkLoss from both the local and remote iMcV-FiberLinX-II modules. LFPT is enabled
by turning on both FX and TX LinkLoss on both modules. This feature allows either
end of the conversion to detect a link fault occurring at the other end of the media
conversion chain.
1. A cable fault occurs on the remote twisted pair.
2. TX LinkLoss detects the fault and disables the OPTICS (or UPLINK) port.
3. FX LinkLoss detects the fiber loss and disables the DATA port.
The link fault is passed through the media conversion and is observed at each end. It
acts just like it would if the devices were directly connected.
NOTE
FiberAlert can also be added to the remote side of the pair to further assist in
locating a fault.
Last Gasp
The iMcV-FiberLinX-II includes a Last Gasp feature, which sends a trap “Flinx Unit
Down” for the Host unit or a “Flinx Remote Unit Down” for the Remote unit (as seen
in iView²) when the power to the module fails.
