The FMB-X-2.5 also sounds a continuous audible alarm when an optical link fails in AUTO mode, even if the
other fiber has a valid link. This informs the operator of a fiber fault that otherwise might not be noticed, as the
switchover from one fiber to the other is often seamless. The alarm can be turned off by briefly forcing the
toggle switch to the active fiber in manual mode and then back to the automatic setting. The FMB-X-2.5 alarm
can also be disabled via software commands.
A plan view of the console FMB-X-2.5 is shown below. The 1310/1550 nm singlemode WDM coupler is not
visible and is mounted on the underside of the optical daughtercard below the dual LC bushings shown.

that both DIP switches (SW1 and SW2) are typically configured at the factory and therefore the
settings should never be changed from their original positions.
