DIAGNOSTIC FEATURES
The OmniRepeater 400FTD diagnostic features make it easy to install and maintain.
There are three levels of diagnostics: Self Test, Fiber Installation Test, and run-
time activity and error monitoring.
Self Test
The power-on self test ensures that the OmniRepeater 400FTD is fully operational.
When power is applied to the unit, self testing occurs. At the end of the self test, all
four LEDs will illuminate for half a second, then green for half a second. After that,
the POWER LED will remain green providing a continuous indication that the
external power supply is operational.
Fiber Installation Test
The OmniRepeater 400FTD includes a built-in fiber installation tester. The fiber
installation test mode may be activated by moving the TEST witch to the TEST
position (up). This diagnostic feature provides the installer with a visual indication
that the fiber optic cabling is intact and correctly installed. During the fiber test
mode a valid frame is continuously transmitted over the fiber optic link. Any
Omnitron 5250 fiber device (such as the OmniStar 400, the OmniMux 400, or the
OmniMux 400XL) at the far end of the fiber optic cable will illuminate its fiber optic
activity LED when the fiber optic cable is unbroken and the transmitting fiber is
correctly connected at the far end device receive port.

If the fiber optic cables are unbroken, the fiber link LED will illuminate green. As
before, note that the fiber test mode LED will be red, and the Power LED will be green.
NOTE: TURN OFF THE FIBER INSTALLATION TEST MODE TO RETURN TO
NORMAL OPERATIONAL MODE.
Fiber Optic Media Test - 2 OmniRepeater 400FTD’s
To test the integrity of fiber optic cables that are already installed, use two
OmniRepeater 400FTD units connected to each other in TEST mode. If the fiber
media is unbroken, the link LEDs on each unit will illuminate green.
Again, note that the fiber test mode LED will be red and the Power LED will be green.
NOTE: TURN OFF THE FIBER INSTALLATION TEST MODE TO RETURN TO
NORMAL OPERATIONAL MODE.

Loopback Fiber Optic Media Test - Via Patch Panel
To test the ingrate of the fiber optic cables when fiber cables are already installed
to a patch panel, use a short patch cord to loopback the fiber optic pair attached to
the OmniRepeater 400FTD.
