Installing Equipment for Each Channel in Subsites

When and where to use:

Procedure:

1. Install the MLC 8000 Subsite Link Converter.
   1. Install the MLC 8000 in a rack or cabinet.
      See “Installing MLC 8000” in the MLC 8000 Comparator Feature Guide.
   2. Mount the MLC 8000 on a tray.
      See “Mounting MLC 8000 on the Tray” in the MLC 8000 Comparator Feature Guide.
   3. Ground the MLC 8000 on a tray.
      See “Grounding an MLC 8000 in a Tray” in the MLC 8000 Comparator Feature Guide.
   4. Install the MLC 8000 REF Input Signals to connect the MLC 8000 to the Time Reference (GPS). See “Installing MLC 8000 REF Input Signals for IP Simulcast System” in the MLC 8000 Comparator Feature Guide.
      NoteThe assumption is that the Simulcast Site Reference device is installed and running, providing a synchronized REF composite signal. The Time Reference (GPS) is not needed if the MLC 8000 Subsite Link Converter is connected to an Rx only BR
   5. (For rack-mount installation) Install the MLC 8000 tray in a rack.
      See “Installing MLC 8000 Tray in Rack” in the MLC 8000 Comparator Feature Guide.
   6. (For cabinet-mount installation) Install the MLC 8000 tray in a cabinet.
      See “Installing MLC 8000 Tray in Cabinet” in the MLC 8000 Comparator Feature Guide.
2. Ground the MLC 8000 tray installed in the rack or cabinet.
   See “Installing MLC 8000” (step 2) in the MLC 8000 Comparator Feature Guide.
3. Connect the MLC 8000 to power by connecting the DC cable of the power supply unit to the DC inlet of the MLC 8000.
   See “Installing MLC 8000” (step 3) in the MLC 8000 Comparator Feature Guide.
4. Is MAC Port Lockdown used on the system? (Disable MAC Port Lockdown if applicable)

   If…	Then…
   Yes	For K core systems, disable MAC Port Lockdown on the site LAN switch. See “Disabling MAC Port Lockdown Using an HP Switch Service Port” in the MAC Port Lockdown Feature Guide.
   	For M series and L series zone core systems, disable MAC Port Lockdown on the site LAN switch with a Saved Command in UNC. See “Disabling MAC Port Lockdown Using a VoyenceControl Template” in the MAC Port Lockdown Feature Guide.
   	Determine the switch configuration, to find an unused port. See “HP Switches – Determining Port Connections in ASTRO 25 Systems” in the Ethernet LAN Switches Feature Guide.
   No	For K core systems, enable and configure unused ports on switches. Enable all the ports on the switches. See “Enabling/Disabling Ports on HP Switches Using Local Access” in the MAC Port Lockdown Feature Guide.
   	For M series and L series zone core systems, enable and configure unused ports on switches. See “Enabling/Disabling Ports on HP Switches Using VoyenceControl” in the MAC Port Lockdown Feature Guide.

5. Connect the MLC 8000 Subsite Link Converter to the switch.
   See ASTRO 25 Conventional Mixed-Mode Simulcast Voting Subsystem Equipment Cabling.
6. Connect the MLC 8000 Subsite Link Converter to the base radio.
   NoteFor Conventional Mixed-Mode Voting Simulcast, all base radios must be G-Series Generation 2. See “GTR 8000 Base Radio FRU Procedures, Transceiver Hardware Generations” in the RF Site Technician Reference Guide.
7. Configure the base radios to interface with the MLC 8000 devices.
   See GTR 8000 Configuration Settings.
8. Optional: Connect the MLC 8000 Analog Comparator to the SDM3000 RTU.
   See Cabling MLC 8000 to SDM3000 RTU.
9. Push new configuration files down to the switches and GGM 8000 gateways.
   • For K core systems (distributed conventional architecture), use Configuration Manager to push the configuration files. See “Downloading the Full Configuration to a Device” in the Configuration Manager for Conventional Systems User Guide.
     NoteFor a K core system, the service PC is used to install the configuration files for the gateways and switches.
   • For M series and L series zone core systems, use UNC to push the configuration files. See “Distributing Configurations For Transport Devices through the UNC Wizard” in the Unified Network Configurator User Guide.
10. Reboot the gateways. Using a terminal program, type rb (ReBoot) and press ENTER.
    The switch reboots automatically after pushing the new configuration.
11. Turn on power to the MLC 8000 by connecting the AC cord of the power supply unit to the AC wall-mount power outlet (110-240 VAC, 50/60 Hz).
    NoteThe AC power outlet should be as near as possible to the equipment and should be accessible. Ensure that the cable is not routed with tension.
    See “Installing MLC 8000” (step 6) in the MLC 8000 Comparator Feature Guide.
    1. Verify the MLC 8000 power LED turns RED (which indicates the MLC 8000 is in booting state) and after a while, it turns GREEN.
