VOLUME III, CHAPTER 3, INU AND INUE INSTALLATION
Installation Procedure
1. Fit the rack mounting brackets to the chassis with the grounding stud to left
or right side for the most direct ground wire path to the rack ground bar.
2. Locate the INU/INUe in the equipment rack and secure it using four No.12
Phillips dome-head screws from the IDC installation kit.
3. Ground the INU/INUe from the grounding stud to the rack/frame ground
bar using a length of 4mm2 (AWG12) green PVC insulated stranded copper
wire with a suitably sized ground lug at the ground bar end (supplied by the
installer). The grounding stud accommodates ground cables up to 16 mm
2
(AWG 6). The stud also provides jack plug connection for a wrist strap.
4. If the equipment rack/frame requires grounding, use 16mm2 (AWG6) wire
from its ground bar to the station ground.
Grounding Safety:
o
Do not assume that an existing rack or mounting frame is correctly
grounded. Always check the integrity of the ground connections, which
must include a check through to the master ground for the station, which
should be located at the point of cable entry to the equipment building.
Ground wires must provide a direct, low impedance path to the master
ground bar.
o
Do not connect other equipment to the same grounding cable as the INU.
Each item of equipment in a rack must be separately grounded to the rack
ground bar.
o
The INU must be located in the same immediate area (adjacent
racks/cabinets) as all other equipment with a (ground) connection to a
common DC supply source.
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
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. Fit the supplied jumper cable between the RAC and ODU cable, or where
required to a lightning surge arrestor. Secure the cable within the rack/frame
using cable ties or similar. If the jumper cable is too short, make an
extension cable.
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 86.
