Initial Power-up Tests
Power-up Procedures
WARNING
Potentially lethal voltage and current levels are routed to the
BTS equipment. This test must be performed with a second
person present, acting in a safety role. Remove all rings, jewelry,
and wrist watches prior to beginning this test.
DC Input Power
In the tests to follow, power will first be verified at the input to each
BTS frame. After power is verified, cards and modules within the frame
itself will be powered up and verified one at a time.
Before applying any power, verify the correct power feed and return
cables are connected between the power supply breakers and the power
connectors at the top of each BTS frame. Verify correct cable position
referring to Figure 2-3 on page 2-8 for +27 V systems and Figure 2-5
on page 2-10 for -48 V systems.
CAUTION
Always wear a conductive, high impedance wrist strap while
handling any circuit card/module to prevent damage by ESD.
Extreme care should be taken during the removal and installation
of any card/module. After removal, the card/module should be
placed on a conductive surface or back into the anti-static bag in
which it was shipped.
NOTE
For positive power applications (+27 V):
The positive power cable is red.
The negative power cable (ground) is black.
For negative power applications (-48 V):
The negative power cable is red or blue.
The positive power cable (ground) is black.
In all cases, the black power cable is at ground potential.
Motorola recommends that the DC input power cable used to connect the
frame to the main DC power source conforms to the guidelines outlined
in Table 2-4.

NOTE
If Anderson SB350 style power connectors are used, make sure
the connector adapters are securely attached to each of the BTS
power feeds and returns. Also, make sure the cables have been
properly installed into each connector.
