OS-1933-E3-003 OS System Configuration3-6 044-05243 Rev AActivate Rectifier ModulesActivate 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 sta-tus.Table 3-4 Activate Rectifier ModulesStep Action1Select the System/Configuration Page.

See Figure 3-17.5Verify the correct TMA channels have the correct current draw per the specifications of the TMA. Currents less than 40mA or greater than 150mA will assert a fault. Currents greater than 450mA will crowbar the power source. The system will retry every 5-minutes to enable the channel in the event the short is remedied. A crowbar can also be reset by configuring the channel disabled and then enabled.

044-05243 Rev A 4-1Chapter 4MaintenanceIntroductionThis chapter provides periodic maintenance and removal and replacement procedures for the OS-1933-E0-003 Outdoor MCPA System.Periodic MaintenanceSuggested 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 fac-tory.Cleaning Air Inlets/Outlets/FilterThe air inlets and outlets should be cleaned during periodic site maintenance. If the equipment is operated in aheavy industrial or severe dust environment, the inlets and outlets should be cleaned as necessary. Coolingefficiency can be reduced if dust and dirt are allowed to accumulate. Remove the panel and, using eithercompressed air or a brush with soft bristles, loosen and remove accumulated dust and dirt from the air inletand 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.Table 4-1 Periodic MaintenanceTask Interval ActionCleaning:Filters 12 months Inspect and clean air filters.Air Vents During periodic site maintenanceInspect 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.Inspection:Cables and ConnectorsDuring periodic site maintenanceInspect signal and power cables for frayed insulation. Check RF connectors to ensure tightness.
OS-1933-E3-003 Troubleshooting4-2 044-05243 Rev ATroubleshootingStatus of each individual module can be determined by the status of the LED (MCPAs, Rectifier, Controllerrepresents system and RFCUs). All LEDs should illuminate a solid green; any other indication requires accessto the Status / Alarm page. Some common alarms and there remedies are detailed in the following sections.MCPA does not have a solid green LED Table 4-2 MCPA - no solid green LEDLED Color Status ActionRed Solid Open Status / Alarms page for details about the MCPA fault.No LED No LED Check Power system or verify the appropriate fuse located on the rear of the power system.Yellow BlinkingThe MCPA is measuring >50W of reflected power.i. Ensure that the TX/RX ANT ports are terminated adequatelyii. 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.Yellow SolidThe 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.Red/Yellow BlinkingFirmware is not loading correctlyi. Extract module from the OS systemii. Place the front panel switch in the ON position (middle)iii. Re-insert the MCPA into the OS systemiv. Latch to top and bottom fasteners.Green BlinkingThe MCPA is ready to enable, but something in the system is preventing this. Check the followingi. 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.iv. View the Status/Alarm page for more detailsv. 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-E3-003044-05243 Rev A 4-3Rectifier 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 tothe Status/Alarm page for exact details. Reference the Rectifier Module section in Chapter 2 for the procedureon 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 powersystem. A non-crossover network cable could be temporarily installed to validate the connection. Rectifier Voltage FaultMeasure the AC input and/or DC Output (all 4 fused outputs) and validate that the voltage is within thespecified 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 clo-sure and allow the fan to operate.• The OS System components are not >41 C. Fans do not operate below this threshold.RFCU AlarmsStatus/Alarm Page Faults – Bypass V, 5V, LNA Alarm 1/2 could be an indication of a bad RFCU. Replace theRFCU 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.
