OC-12 Low Speed (R1.1)
Testing Procedure
Perform the following steps for all Metropolis
®
DMXtend shelf
Function Unit or Growth slots containing OC-12 (LNW46) OLIU
(Supported in release R1.1 and later) circuit packs.
Important!
When reference is made to optical fiber loopback
connections to IN and OUT on the OLIU, make the connections at
the LGX equipment in order to verify correct installation and
labeling of the fibers.
LBOs are installed on the OLIU faceplate IN port.
Step 1
Beginning from the top (G) side of the Metropolis
®
DMXtend shelf,
locate the first Function Unit slot that contains an OC-12 OLIU circuit
pack.
............................................................................................................................................................................
Step 2
Insert a 15 dB LC-type LBO into the top
IN
connector (Port 1) of the
OC-12 OLIU. Refer to Appendix C, Installing Fiber Connectors and
LBOs.
Connect the fibers labeled IN and OUT from the LGX to the OLIU
(Port 1).
............................................................................................................................................................................
Step 3
Connect the Port 1
OUT
connector to the Port 1
IN
connector (at the
LGX) of the OC-12 OLIU, using an optical fiber jumper cable. Refer to
Appendix B, Fiber Cleaning for proper fiber cleaning instructions.
Requirement:
The FAULT LED on the OC-12 OLIU will begin flashing and the
MN
and
NE
LEDs should be lit on the SYSCTL circuit pack.
After approximately 20 seconds the flashing
FAULT
LED should extinguish
on the OC-12 OLIU and the FAULT,
MJ
and
NE
LEDs should be lit on
the SYSCTL circuit pack.
............................................................................................................................................................................
Step 4
Remove the optical fiber jumper from the OC-12 OLIU (at the LGX).
Result:
The FAULT LED should begin flashing on the OC-12
OLIU and only the MN and NE LEDs should be lit on the SYSCTL
circuit pack.
............................................................................................................................................................................
Step 5
Use the scroll bar in the
Command Builder
window to scroll down to
the
upd-sys
command. Click on the
upd-sys
command.
