Activate TMA Channels (2 per Sector)
CAUTION: This parameter sources +12 V at 500 mA maximum to antenna ports. Caution should be used
if antenna ports are connected to test equipment with 0 VDC tolerance.
To prevent a short circuit and alarm situation, all antenna port connections must be complete prior to
enabling TMA DC supplies.
NOTE: These configurations enable DC voltage at antenna ports and enable RX fault monitoring.
Each Rx channel sources +12 V at 500 mA maximum. Any current less than 40mA will generate a LO
CURRENT fault. Any current greater than 150mA will generate a HI Current fault. Any current greater than
500 mA will disable the DC source for that channel and generate a HI CURRENT fault.
A HI CURRENT condition attempts to auto-recover every five minutes by enabling the DC to Rx channel. If
fault condition is cured, alarm clears and source remains on. If fault is present, there is no change in status.

Maintenance
Introduction
This chapter provides periodic maintenance and removal and replacement procedures for the OS-1933-E0003 Outdoor MCPA System.
Periodic Maintenance
Suggested periodic maintenance requirements are listed in Table 4-1.
WARNING: Wear proper eye protection to avoid eye injury when using compressed air.
CAUTION: Use only dry compressed air when cleaning the OS, do not use pressure washers.
To ensure proper cooling and prevent MCPA over temperature shutdown, one of the two booster doors
must be closed and secure at all times.
NOTE: Do not break the seals on equipment under warranty or the warranty will be null and void. Do not
return equipment for warranty or repair service until proper shipping instructions are received from the factory.

During periodic
site maintenance
Inspect and clean inlet and outlet air vents. If equipment is
operated in a dusty or industrial environment, inlets and outlets
should be inspected more often.
Inspect signal and power cables for frayed insulation. Check RF
connectors to ensure tightness.
Cleaning Air Inlets/Outlets/Filter
The air inlets and outlets should be cleaned during periodic site maintenance. If the equipment is operated in a
heavy industrial or severe dust environment, the inlets and outlets should be cleaned as necessary. Cooling
efficiency can be reduced if dust and dirt are allowed to accumulate. Remove the panel and, using either
compressed air or a brush with soft bristles, loosen and remove accumulated dust and dirt from the air inlet
and outlet panels. Replace the panel when cleaned.
The air filters, located in the front and rear panels, also must be removed and cleaned using compressed air.
Refer to Air Filter Cleaning, page 4-10,Table 4-9, Figure 4-6 for filter cleaning and replacement instructions.

Status of each individual module can be determined by the status of the LED (MCPAs, Rectifier, Controller
represents system and RFCUs). All LEDs should illuminate a solid green; any other indication requires access
to the Status / Alarm page. Some common alarms and there remedies are detailed in the following sections.
MCPA does not have a solid green LED

Red/Yellow Blinking
Open Status / Alarms page for details about the MCPA fault.
Check Power system or verify the appropriate fuse located on the
rear of the power system.
The MCPA is measuring >50W of reflected power.
i. Ensure that the TX/RX ANT ports are terminated adequately
ii. Ensure that the MCPA is installed fully and the latches are
secured.
iii. Try reseating the MCPA; disable the MCPA by the front panel
switch (down) before removing.
iv.If not remedied the MCPA will shutdown in one minute. If shutdown
for VSWR, the MCPA will require a manual reset with the front panel
switch (up position) to recover.
The MCPA has reduced gain to compensate for an excessive input
level.
i. Ensure the input sources are within the specified power levels.
ii. Ensure the TX Gain is configured in accordance to the
specifications in Section 5.
iii. The MCPA can only compensate for 6dB. The MCPA could
disable and require a manual reset via the front panel switch (up
position).
iv. Operating the OS System equipment under this condition could
manifest into a system shutdown due to excessive temperature and/
or RF power.
Firmware is not loading correctly
i. Extract module from the OS system
ii. Place the front panel switch in the ON position (middle)
iii. Re-insert the MCPA into the OS system
iv. Latch to top and bottom fasteners.
The MCPA is ready to enable, but something in the system is
preventing this. Check the following
i. Verify the Sector is enabled via the System/Configuration page,
Installed section.
ii. Attempt re-seating the MCPA and ensuring the latches are locked.
iii. Try another MCPA.
Green Blinking
iv. View the Status/Alarm page for more details
v. If the communication to the system cannot be established the
controller is not operating. Cycle the AC source to restart the system.
vi. Ensure DC power is getting to the controller; check the fuse on the
rear of the power system. Measure the +28.5Vdc on the controller
JX.
vii. Replace controller. See page 4-7.

Troubleshooting OS-1933-E3-003
Rectifier Module with a Red LED or Individual Faults
– Any rectifier module fault is remedied by replacing a known good module with the suspected unit. Refer to
the Status/Alarm page for exact details. Reference the Rectifier Module section in Chapter 2 for the procedure
on Rectifier Module replacement.
RECT ALL COMM Fault
Could to the result of a bad RJ45 interface cable at the rear of the system linking the controller with the power
system. A non-crossover network cable could be temporarily installed to validate the connection.
Rectifier Voltage Fault
Measure the AC input and/or DC Output (all 4 fused outputs) and validate that the voltage is within the
specified range detailed in section 5.
Fans Not Operating –
• Check the status of the fans on the Status/Dynamic page.
• The fan of a specific door will not operate if that door is not secured. Ensure that the front and rear
doors are secured and that both fans are operating any time there is a site visit.
• The fan circuitry has an auto-resettable fuse. Unplugging a bad fan and installing a known good fan
should reset the fuse. The intrusion plunger must be pulled to the out position to simulate a door closure and allow the fan to operate.
• The OS System components are not >41 C. Fans do not operate below this threshold.
RFCU Alarms
Status/Alarm Page Faults – Bypass V, 5V, LNA Alarm 1/2 could be an indication of a bad RFCU. Replace the
RFCU module per the procedure in the RFCU section of Chapter 2.
RF Performance Issues -
• No power out or gain:
• View the Status/Alarm page correct all detected alarms
• Disable the MCPA to force the sector into bypass, using external measuring equipment validate the
RF passing through the OS System.
• Disable the MCPA first then reseat the MCPA and RFCU modules, enable the MCPA
• Replace the MCPA and/or RFCU with a known good module.
