OS-1933-E3-003 OS System Configuration Activate Rectifier Modules Table 3-4 Activate Rectifier Modules Step Action Select the System/Configuration Page. See Figure 3-15. Using the pull-down menus in the Rectifier/Installed section, choose YES to activate the Rectifier Modules. Reference the rectifier positions detailed on the front rack ears of the power system. Default is NO. Choose SUBMIT to accept and apply the changes. To abort changes choose another page without applying submit. 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. Table 3-5 Activate TMA Channels Step 3-6 Action Select the System/Configuration Page. See Figure 3-15. Using the pull-down menus in the TMA Main/Diversity sections choose ENABLE for the TMAs to be utilized. Default is DISABLED Choose SUBMIT to accept and apply the changes. To abort changes choose another page without applying submit. Navigate to the Status / Dynamic page. See Figure 3-17. Verify 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 OS System Configuration OS-1933-E3-003 Adjust LNA Gain Table 3-6 Adjust LNA Gain Step Action Select the System/Configuration Page.

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. Table 4-1 Periodic Maintenance Task Interval Action Cleaning: Filters Air Vents 12 months Inspect and clean air filters. 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. During periodic site maintenance Inspect signal and power cables for frayed insulation. Check RF connectors to ensure tightness. Inspection: Cables and Connectors 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. 044-05243 Rev A 4-1 OS-1933-E3-003 Troubleshooting Troubleshooting 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 Table 4-2 MCPA - no solid green LED LED Color Red No LED Yellow Yellow Red/Yellow Green 4-2 Status Solid Action Open Status / Alarms page for details about the MCPA fault. No LED Check Power system or verify the appropriate fuse located on the rear of the power system. Blinking 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. Solid 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. Blinking 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. Blinking 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. 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. 044-05243 Rev A 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. 044-05243 Rev A 4-3
