• RBS: The RADIOBLADE STATUS LEDs will light red and then green for each present
RadioBlade. If no RB is present, the LED will not light. To verify the contents of the RBS,
pull out the shelf (powering off is not required) and inspect the RadioBlades and their
respective status LEDs. Reinsert the RBS. To do this, press up on one side rail locking
arm and press down on the other side rail locking arm, and then push the unit into the
rack (see the following illustration).
• BIC CRIC and AIC CRIC: The POWER and STATUS LEDs will light red and then green.
All other BIC and AIC card LEDs will light green.
10 Using the breaker on the PDU, turn up each RF Shelf and then verify that each RF Shelf is
operational before proceeding. The POWER and ALARM LEDs on the front of the RF Shelf
will light green.
11 Complete the procedures in sections 5.4, 5.5 and 5.6.
7.10 TOR Tx Measurement Procedure
1 Measure the output from the Tx 1, Tx 2, and Tx 3 connectors at the top of the cabinet using a
digital RF power meter.
NOTE: Test only the Tx 1 connector in an omni configuration.
2 Adjust the power budget of the DAS using the variable TX ATTENUATION knobs on the front
panel of each RF Shelf.
The outside knob adjusts in 10 dB increments, and the inside knob adjusts in 1 dB
increments, up to 50 db maximum.
NOTE: The variable attenuators only impact the RF downlink. If large values of attenuation
are required, consider adding external attenuation to the uplink of the Rx port to maintain link
balance.
3 Make sure the Nextel-provided coax jumpers have been swept.
4 Connect the jumpers between the TOR Tx 1 and DAS RF IN, and then connect the jumpers
between the TOR Rx 1 and DAS RF OUT.
In a sectored MC-Series System, connect the jumpers to the DAS commensurate with the
sector coverage area and hub locations per Nextel design.
5 Measure the output at the DAS remote unit(s) to verify power budget accuracy.
