3. Use lightguide jumpers to loop the IN and OUT connectors of the MAIN-1
OLIU. See Table A.
Response: FAULT LED on SYSCTL flashes.
ACTIVE LED remains on.
Lighted major (MJ) or minor (MN) LED remains lit.
[It may take 1 minute or more for LEDs and alarms to
stabilize after the OLIU(s) are looped].
If responses are not correct, check connections and
looping fibers. Clean connectors and repeat Step 3.
If responses are still not correct, replace OLIU.
4. For the 26G-U/26G2-U OLIU, replace the 0 dB LBO on the OUT or IN buildout
block(s) with the required 15 dB LBO on the MAIN-1 OLIU. For the
29G-U/29H-U OLIU, replace the 0 dB LBO on the OUT or IN buildout block(s)
with the required 10 dB LBO on the MAIN-1 OLIU. See Tables B or C.
5. Use lightguide jumpers to loop the IN and OUT connectors of the MAIN-2
OLIU. See Table A.
Response: FAULT LED stops flashing.
ACTIVE LED remains on.
Major/Minor (MJ/MN) alarm goes off.
6. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
7. The 22F-U/22F2-U/22G2-U/22G3-U/22G4-U/28G-U/28G2-U OLIUs require
single-mode lightguide jumpers and 0 dB LBOs. The 22D-U OLIU requires
multimode lightguide jumpers and 0 dB LBOs. See Tables A, E, and D.
8. Use lightguide jumpers to loop the IN and OUT connectors of the MAIN-1 or
FN-1 OLIU. See Tables A and E.
Response: FAULT LED on SYSCTL flashes.
ACTIVE LED remains on.
Lighted major (MJ) or minor (MN) LED remains lit.
[It may take 1 minute or more for LEDs and alarms
to stabilize after the OLIU(s) are looped].
If responses are not correct, check connections and
looping fibers. Clean connectors and repeat Step 8.
If responses are still not correct, replace OLIU.
