Chapter 3 Installing the TimeProvider

Making Connections

14.Connect an RG58 (060-58545-xx) cable between the lightning suppressor and the TPIU. See Table 2-4for specific cable lengths.

If you are using the integrated IMC/TPIU, install the appropriate converter cable (060-58041-03, 1 m/3 ft, right angle connector or 060-58042-03, 1 m/3 ft, straight connector) to the DB15 GPS connector on the main shelf. Connect the other end of the converter cable to the RG58 cable from the lightning suppressor.

15.Install fire-stopping material in all holes opened in the roof and/or walls during this procedure.

16.Check all connections for tightness to prevent arcing and intermittent operation.

17.Coat all exposed connectors with an electrically conductive antioxidant compound (e.g. Kopr-Shield spray).

Installing the Integrated IMC/TPIU

You install the integrated IMC/TPIU in the IMC slot in either TimeProvider main shelf, as shown in Figure 1-4. Use the installation procedure described in Replacing the IMC or IMC/TPIU, on page 163.

Installing the TPIU

You mount the TPIU on a rack near the TimeProvider main shelf. Symmetricom supplies the connecting cable (060-58543-xx or 060-58544-xx) in several lengths, as listed in Table 2-4. The Integrated GPS Antenna kit (990-58545-01 or

990-58545-02) is delivered with a 1m/3 ft. interconnect cable. Mount the TPIU to the rear rails of the rack using the provided rack ears. Install the TPIU so that the front panel is on the same side as the Output modules. Figure 3-25and Figure 3-26illustrate alternate mounting schemes.

To connect the TPIU to the shelf, attach the DB15 interconnect cable (060-58543-03 or 060-58544-03) to the connector labeled “GPS” on the TimeProvider shelf. This connector is on the front panel of the Model 1000 and on the rear panel of the Model 1100. Connect the other end of the cable to the DB15 connector on the TPIU.

To use the GPS signal, set the TimeProvider to the PRR mode, as described in Provisioning the IOC, on page 105, or enable the GPS input when in SSU mode.
