2.5.3 Power Up the MCPS2000
☛ Important: Read and understand the following steps before taking any action.
38. Switch on the DC input power to the MCPS2000. Measure the input voltage at
the bus bar connections at the rear of the unit and verify it is 27VDC. Adjust the
power supply if necessary.
The MCPS2000 AMM
POWER LED should be GREEN, indicating that the unit
is functional and that in input voltage is between 24 and 28 VDC. If the
POWER LED is amber, red, or does not light, turn off the DC input power and
correct the power supply fault.
The MCPS2000 RF modules will automatically be ENABLED. All four LEDs
on each MCPA module should be GREEN.
To DISABLE an RF module, set the front panel ENABLE/DISABLE switch to
DISABLE; the
ENABLE LED will be RED.
39. Wait 5 minutes for the MCPS2000 to reach a stable operating temperature and
to charge the real-time clock backup power. DO NOT apply commercial traffic
signal power during this time.
40. If the MCPS2000 is connected to a remote operations center via one of the rear
panel interface connections, verify no alarms have been reported.
41. Verify that all MCPS2000 LED indicators remain GREEN.
42. If any LED indicators are AMBER or RED, then RF modules are disabled or
there is a problem which much be remedied before continuing.
If no problems are encountered, continue to the next step, determining the
required RF input drive power as described below.
2.5.4 Determine the required RF input power
☛ Note: The MCPS2000 should be powered on and enabled before the RF input
power is applied.
43. Before applying the RF input power to the MCPS2000, determine the input
drive level and output power needed for each channel being amplified by using
the attached worksheet.
44. Before applying RF input power to the MCPS2000, verify that the applied RF
input power for a single channel and the sum of all channels is below the
calculated maximum rated RF input.
Once the required RF input power for each channel is determined, continue to the
next step, setting the RF input drive power.
2.5.5 Set RF input drive power for each channel
☛ Note: If RF Input Cable is connected to the MCPS2000, disconnect it from the
MCPS2000 and connect it to the Power Meter for the following step.
45. Switch on the RF input drive power at the customer provided host system
exciter following the instructions supplied with your RF source equipment.
