VOLUME III, CHAPTER 3, INU AND INUE INSTALLATION
connected. This does not apply to tinned, solder-plated, or silver-plated
connectors and other plated connection surfaces but all must be clean
and free of contaminants.
o
All raceway fittings must be tightened to provide a permanent low-
impedance path.
5. Install the plug-ins in their assigned slot positions, and check that their
front panels are flush-fitted (not protruding) and held secure by their
fasteners. Ensure unused slots are covered by blanking panels.
o
If a FAN air filter is required, fit it prior to inserting the FAN.
o
Install the CompactFlash (CF) card in the NCC; insert in the socket on
the right side of the PCB.
o
The CF card holds configuration, software load, and license data.
o
Each CF card is identified by a unique serial number; which is the license
number for the Eclipse terminal.
6. For an IRU 600 installation fit the supplied jumper cable between the RAC
and its companion IRU 600 RFU.
7. Fit NMS cables, DAC tributary cables, and where required, AUX cables. For
data on the cable sets, refer to INU/INUe Cable Assemblies on page 77.
The following steps describe the procedure for installing the power cable, and pre-
paring for power-on. Do not connect the power until all steps have been completed.
8. 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) should have a capacity of 12A for the INU and a 25A for the INUe,
however these ratings can be adjusted in line with the number of cards
installed, and hence power consumption. For power consumption data, see
Power Supply on page 61.
9. For a -48 Vdc supply, connect the blue wire to -48Vdc (live), and the black
wire to ground/+ve. (Power input on the NCC and NPC is polarity
protected).
10. For a +24 Vdc supply, connect the blue wire to +24Vdc (live), and the black
wire to ground/-ve. (Power input on the PCC is polarity protected).
11. Measure the voltage on the dc power connector.
o
For -48 Vdc operation the voltage should be -48Vdc, +/-2Vdc for a non
battery floated supply, and nominally -56 Vdc for a battery floated supply.
(Limits are -40.5 to - 60 Vdc).
o
For +24 Vdc operation the voltage should be 24 +/- 2Vdc for a non battery
floated supply, and nominally 30 Vdc for a battery floated supply.
(Operating limits are 20 to 36 Vdc).
