This will ensure that no units of thesystem will be damaged during turn-up and that all existing systems will continue to functionproperly.1.2.1 Host Unit Installation ChecksComplete the following checks at the HU prior to starting the turn-up process:1. Verify that the ON/OFF switch on the HU is in the OFF position (press O).2. At the fuse panel, install a 3 Amp GMT fuse in the circuit that supplies DC power to the HU.3. Using aDC voltmeter, verify that the DC voltage level at the HU power terminals isbetween ±24 or ±48 Vdc (can be either polarity).4. Verify that all electrical and optical connections have been completed and that all opticalfibers, coaxial cables, and wires are properly routed and secured.1.2.2 Remote Unit Installation ChecksComplete the following checks at the RU prior to starting the turn-up process:1. Verify that the ON/OFF switch on the STM is in the OFF position (press O).2. Verify that the MUTE/NORM/RESET switch on the LPA in the MUTE position.3. At the AC breaker box, close the circuit breaker for the circuit that supplies AC power tothe RU.4. Using an AC voltmeter, verify that the AC voltage level at the AC outlet is between 110and 120 Vac (for 120 Vac powered systems) or between 220 and 240 Vac (for 240 Vacpowered systems).5. Verify that all electrical and optical connections have been completed and that all opticalfibers, coaxial cables, and wires are properly routed and secured.2 TURN-UP SYSTEM AND VERIFY OPERATIONThe process of turning-up the system and verifying operation involves powering up the varioussystem components, verifying that the LED indicators show normal operation, setting the sitenumber and name, adjusting the RF signal levels, and adjusting the path delay.
ADCP-75-150 • Preliminary Issue A • March 2003 • Section 4: OperationPage 4-3©2003, ADC Telecommunications, Inc.2.1 Turn-Up ProcedureUse the following procedure to turn-up the system:1. Temporarily disconnect the external alarm system or notify the alarm system provider thattesting is in progress.2. If turning-up multiple HU and RU systems that have not been configured for operation before,temporarily disconnect the CAN cables from the NET IN and NET OUT ports of each HU.3. Determine if the forward path composite input signal level at the Host Unit FORWARD RF INport is appropriate for the required RF output signal level and adjust by installing an externalattenuator if necessary. Refer to Section 2.3 for the calculation and adjustment procedure.4. Connect the DEMS computer (if not already connected) to the SERVICE connector on theHU or STM front panel. If necessary, aseparate laptop computer loaded with the DEMSsoftware can be temporarily connected and used to initially configure the system.5. Place the ON/OFF switch on the HU in the ON position (press I).6. Make sure the switch on the LPA is in the MUTE position and then place the ON/OFFswitch on the STM in the ON position (press I).7. Wait 6to 8seconds for the HU and the RU modules to initialize and then observe the LEDindicators on the HU, STM and LPA. Refer to Section 5 for the troubleshootingprocedures if the indicators do not respond as specified.8. Start up the DEMS software program. The DEMS main window will open as shown inFigure 4-1.Note: The DEMS software should be installed on aPC-type computer and thePC’s COM port should be configured to interface with the HU. For information aboutinstalling the DEMS software and configuring the PC’s COM port, refer to the DigivanceElement Management System Software User Manual (ADCP-75-125).Note: By default, all HU’s and RU’s are programmed with the same site number andname. This can cause problems for DEMS if multiple HU’s with the same site number andsite name are networked together through the CAN interface. It is therefore advisable totemporarily disconnect the CAN interface cables from the HU until aunique site numberand name can be entered for each HU and its corresponding RU.HOST UNIT SPECTRUM TRANSPORT MODULE LINEAR POWER AMPLIFIERPOWER –Green AC POWER –Green STATUS –Steady greenSTANDBY –Off STANDBY –OffHOST UNIT –Green HOST UNIT –GreenREMOTE UNIT –Green STM –GreenDRIVE –Green, Yellow, or Red PA –GreenPORT 1/PORT 2 – Green VSWR –GreenPORT 1/PORT 2 – Green
