installation.book Page 82 Wednesday, August 6, 2003 6:06 PM Amosphere NPM Installation Procedures (MMDS) Insert CompactPCI Power Supplies The radio and utility shelves each contain two or three identical CompactPCI power supplies. See pages 78 and 80 for the locations of the power supplies. Utility shelves and completely filled radio shelves use three power supplies each; half-full radio shelves require only two power supplies.
installation.book Page 83 Wednesday, August 6, 2003 6:06 PM Chapter 4: Installation Procedures Test CompactPCI Power Supplies This procedure describes how to test the CompactPCI power supplies and shelves for electrical faults. Testing the power supplies and shelves before inserting the cards ensures that, in the unlikely event that an electrical fault does occur, no cards will be damaged.

If the configuration of your NPM basestation does not use a full complement of cards, some slots will be left empty. W A R N I N G : The cards use components that are sensitive to electrostatic discharges (ESD).
installation.book Page 86 Wednesday, August 6, 2003 6:06 PM Amosphere NPM Installation Procedures (MMDS) To insert the cards into the utility and radio shelves 1 Ensure that there are no obstructions in the slot or on the guide rails and check the backplane for bent pins. If there are bent pins, the backplane is damaged and requires repair. Report any damaged equipment to your field support coordinator as soon as possible. 2 Remove the card from its antistatic bag.
installation.book Page 87 Wednesday, August 6, 2003 6:06 PM Chapter 4: Installation Procedures Cover Unused Card Slots Any empty slots in the radio and utility shelves should be covered with filler panels. The filler panels ensure airflow to the other cards and protect the cards from dust and electromagnetic interference. To cover the unused slots with filler panels 1 Remove the filler panel from its protective bag.

The power cables are already tied to the rack. The PDP power cables consist of #10, #12, or #16 AWG wire with 3-pin DSUB connectors on each end. The connectors are secured to the racks with 1/8-inch flathead screws.

The DSUB connectors are secured to their receptacles with 1/8-inch flathead screws. W A R N I N G : Ensure that the main +24V DC power supply for the NPM basestation is powered off before connecting the alarm cables.
installation.book Page 97 Wednesday, August 6, 2003 6:06 PM Chapter 4: Installation Procedures Connect the Ethernet Cables The Ethernet cables are CAT5 cables with RJ-45 connectors on each end. The cables connect radio sector controllers (RSC), utility bus controllers (UBC), Ethernet switches (ES), application hosts (AH), and edge routers. The two Ethernet switches are connected together with a cross-over cable; the other cards use straight-through cables. The Ethernet cabling is done via rear I/O cards.

Table 4.15 shows the origin and termination point of each cable. If you are using an edge router configuration without redundancy, connect Ethernet switch 0 to the edge router by connecting port 1 on the right ES rear I/O card (slots 19–20) to the edge router. Use a straight-through Ethernet cable.
