Chapter 3. Installing the INU and INUe
Vol. III-3-6
page 3-9.
6. Fit the supplied jumper cable between the RAC and lightning impulse surge
suppressor.
7. Secure the cable within the rack/frame using cable ties or similar.
If the jumper cable is too short, make an extension cable. Refer to Jumper Cables
on page 2-23 in Chapter 2.
8. Fit the DAC tributary cables. For data on the tributary cable sets, refer to
Appendix C.
For a DAC 16x, ensure correct orientation of the Mini RJ-21 connector before
pushing it home. This can be checked by the scalloped key to one side of the
connector. Additionally, a trib cable supplied by Alcatel-Lucent will have the cable
exiting to the right side when viewed from the front.
Do NOT over-tighten the Mini RJ-21 retaining screws.
Steps 9 to 14 describe the procedure for preparing the power cable, and preparing
for power-on. Do not connect the power until all steps have been completed.
9. Run the supplied power cable through to the power pick up point, which will
normally be at a circuit breaker panel in the rack. A circuit breaker (or fuse)
must have a capacity of 12 A for the INU and a 25 A for the INUe.
10. Connect the blue (or red) wire to -48 Vdc (live), and the black wire to ground/
+ve. The power input is polarity protected.
11. Measure the voltage on the dc power connector. The voltage should be
-48 Vdc, +/-2 Vdc (limits are -40.5 to - 60 Vdc).
This product meets the global product safety requirements for SELV (safety
extra-low voltage) rated equipment and the input voltage must be guaranteed to
remain within the SELV limits (48 V nominal, 60 V maximum) in the event of a
single internal fault.
Always check the integrity of the dc power supply to an INU/INUe right to its
source. Never assume that the supply provided to the pick-up point in a rack is
correct.
9500 MXC dc power, IF, tributary, auxiliary and NMS cables are not to be routed
with any AC mains power lines. They are also to be kept away from any AC
power lines which cross them.
12. Carry out a complete check of the installation. If all is correct, and the ODU
and ODU cable installation has likewise been completed and checked, the
