Prepare the Installation Location
This procedure applies to installing the base station on a concrete floor and securing the rack using
M12 concrete expansion bolts (called anchor bolts in this document).
By factory default, a base kit is bolt-attached to the rack. Remove the base kit before installing the rack
with the anchor bolts. Also, please be reminded that the isolation pad – a part of the base kit – is
required for the anchor-bolt-installation. For positiong the rack with the adjusting bolts on the floor,
leave the base kit as it is.
Figure 4.5 shows the base station rack outline.

Insert CompactPCI Power Supplies
There are two FlexAlarm modules and two grounding studs on the rear side of the digital shelf, as
shown in Figure 4.22. The FlexAlarm modules are where the power input connectors and circuit
breakers are located.
The module cards are installed into the digital shelf in a standard way that should be familiar to all ser-
vice technicians. The cards can be installed into slots 2 through 20. (Slots 1 and 21 are reserved for the
factory-installed network switches.)
To insert CompactPCI power supplies
1Push the ejector latch handles toward each other (at the same time) while applying forward pressure to
secure the module to the system chassis. See Figure 4.23.
2Secure the captive screws on each ejector latch handle.

WARNING:The power supplies use components that are sensitive to electro-
static discharges (ESD). Make sure you are wearing an approved and regularly tested
grounded wrist strap connected to the grounding point on the PDP. When you handle
the power supplies, hold them by their handles or edges. Do not touch electrical con-
nections, pins, or soldered surfaces.

Test CompactPCI Power Supplies
This procedure describes how to test the digital shelf and the power supplies for it to check the electri-
cal faults. Testing the power supplies and the shelf before inserting the cards ensures that, in the
unlikely event that an electrical fault does occur, no cards will be damaged.
To test CompactPCI power supplies
1Verify that all four circuit breakers are in the OFF (down) position before turning on the power.
2Turn on the CBA7, CBA8, CBB7, and CBB8 on the PDP.
The PWR GOOD LED near each power connector should illuminate. This indicates that the power
source is providing voltage on that feed. If one of these LEDs is not illuminated, check the cabling and
the power source for that feed.
Switch all four circuit breakers to the ON position. It is suggested that you switch on both circuit breakers
on one FlexAlarm unit, and then switch on both circuit breakers on the other FlexAlarm unit.
The FlexCool fan units will begin cooling the chassis and the FlexManager cards will boot automatically.

Insert the Digital Shelf Cards
See Figure 4.21 for the location of each card. If the configuration of your base station does not use a
full complement of cards, some slots will be left empty.
Figure 4.25 shows how to properly insert a card into a shelf.
Figure 4.25
Card Insertion
To insert the cards into the digital shelf
1Ensure 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.
2Remove the card from its antistatic bag.
3Set the two ejectors handles on the card in the open position by turning the handles away from the center
of the front panel.
In the open position, the ejector handles are at an approximately 45° angle from the front panel.
The cards use components that are sensitive to electrostatic discharges (ESD). Make
sure you are wearing an approved and regularly tested grounded wrist strap con-
nected to the grounding point on the PDP. When you handle the cards, hold them by
their handles or edges. Do not touch electrical connections, pins, or soldered sur-
faces.
The pins on the backplane are easily damaged. When inserting cards (especially the
hard disk drives), ensure that the connectors are properly aligned before applying suf-
ficient pressure to seat the card. Apply equal

Macro Base Station Installation Procedures (NPM2000)
4Ensure that the mounting screws are withdrawn enough to allow for the insertion of the card.
Single-slot cards have two mounting screws, one located under each ejector handle.
5Orient the card so that the text on the front panel is right-side up. The guide pins should be located to the
right of the ejector handles.
6Slide the card into the correct slot. Slot locations are shown on Figure 4.21. Use the guide rails to ensure
the connectors are aligned.
7Apply sufficient pressure to fully mate the card by pressing on both ejector handles with equal force. If
present on the card, the guide pins should slide into the round holes located at the top and the bottom of
each slot on the right-hand side.
8Lock the card in the slot by turning the ejector handles towards the center of the front panel.
In the lock position, the ejector handles are at a 90° angle from the front panel.
9Secure the card in the slot by installing the 2.5-mm mounting screws. Torque each screw to 0.36 N•m
(3.2 inch-pounds).
10 Repeat steps 1 to 9 for the remaining cards.

Cover Unused Card Slots
Any empty slots in the digital shelf 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
1Remove the filler panel from its protective bag.
2Single-slot filler panels have two mounting screws. Secure the filler panel in the slot by installing the 2.5-
mm (0.1 inch) mounting screws. Torque each screw to 0.36 N•m (3.2 inch-pounds).
3If the filler panel does move, ensure that the mounting screws are attached to the shelf frame. If neces-
sary, remove the panel and repeat this procedure.
4Repeat steps 1 to 3 until all the empty slots are covered with filler panels.
