2.4.2.1 Install Shelf Subassembly
1. Make certain that adequate vertical space (8RU) within the rack enclosure is
available. Verify that there will be at least 20cm (8 inches) of space behind the
unit when installed for cooling air flow.
2. Put on an ESD protective wrist strap.
3. Unpack the MCPS2000 side mounting rails and attachment hardware and install
them in the rack as shown on the accompanying job sheet.
4. Unpack the MCPS2000 shelf and record its serial number. Ensure the shelf is in
the proper upright vertical orientation and slide it onto the mounting rails.
5. Use the supplied mounting screws to attach the shelf to the rack.
2.4.2.2 Install Modules in Shelf
6. Unpack each RF module. Align each module with the guides in an amplifier
slot and slide the module as far as possible into the shelf, making sure the
module is fully seated. Note that each module weighs approximately 20 kgs (44
lbs); get a helper to assist if necessary. Tighten the fasteners at the bottom of
each faceplate to lock the modules in place.
7. Unpack and install the Amplifier Management Module (AMM) module in the
rightmost slot of the shelf. Tighten the fastener at the bottom of the faceplate to
lock the module in place.
8. Inspect the alignment of the finished installation, and adjust if needed. If no
problems are found, rack installation is complete.
2.4.3 Cable and Wire Connections
2.4.3.1 Connect Chassis Ground Wire
9. Locate the chassis ground stud on the rear of the MCPS2000 for ground wire
attachment.
10. Measure the distance and routing between the MCPS2000 ground stud and an
attachment point to earth ground. Cut a length of #8 AWG insulated (green)
solid copper wire sufficient for the connection.
11. Crimp a ¼”circular lug to one end of the ground wire.
12. Remove the nut and lock washer on the MCPS2000 ground stud. Attach the DC
ground wire lug to the grounding stud on the MCPS2000, and replace the lock
washer and nut. Tighten the nut securely.
13. Connect the other end of the ground wire to the appropriate earth ground.
14. Use a VOM to verify that the resistance between the chassis ground and true
earth ground is less than 100 Ohms.
15. Inspect the finished connection. If no problems are discovered, ground wire
installation is complete.
