METRObility Optical Systems R231-1X, R231-61, R231-14 manual Far End Fault, 3Install the Line Card

Far End Fault

Far End Fault (FEF) is only applicable to the fiber optic port. FEF enables the locally managed access line card to detect a break in the remote card’s fiber port receiver. The remote card sends an alarm to the locally managed card if the remote card has FEF enabled and it loses its receive (RX) fiber link. No alarms are issued if FEF is disabled.

3Install the Line Card

The Radiance access line card offers the ease of plug-and-play installa- tion and is hot-swappable. The card must be firmly secured to the chassis before network connections are made. Follow the simple steps outlined below to install your line card.

NOTE: Proper grounding is recommended (i.e., wear a wrist strap).
