This section provides the bench procedure to install return switches in a Flex Max901e trunk amplifier (P/N FMTExxx-xxxxxxxN) or a Flex Max901e bridger amplifier (P/N FMBExxx-xxxxxxxN) that was purchased without return switches.

    RF Module Replacement The RF module can be installed in the housing in one of two orientations (refer to Figure 7.3). When installing fuses, surge terminators, or brass shorting bars to route AC power, note that the power supply fuses are associated with the RF module ports and not the housing ports. WARNING Hazardous voltages are present.

    Flex Max901e functions. The element management software will automatically recognize the transponder. Requires Windows 2000 or higher. The Flex Max901e can be monitored and controlled through the Value Max transponder. The transponder collects all Management Information Base (MIB) and electronic Module Architecture Profile (eMAP) data and transmits it to the headend.

  • Page 99: Installing The Transponder

    Flex Max901e functions. The element management software will automatically recognize the transponder. Requires Windows 2000 or higher. Note Ensure that the Flex Max901e is balanced according to system design before installing the transponder. Note A Value Max transponder Mounting Kit (P/N 1501024) is available that contains the transponder grounding bracket (P/N 150061-4), two bracket screws (P/N 30039-0102), and the module cover screw (P/N HS0160).

  • Page 100: Setting Transponder Levels

    10 dB below the analog level, then the input into the transponder should be correct. If the Flex Max901e return path has been balanced correctly, the factory-shipped transponder output level of 40 dBmV should be sufficient to achieve a level of –10 to 10 dBmV at the headend.

    Housing Replacement WARNING Hazardous voltages are present. Use approved safety equipment and procedures. Sheath currents may flow through the amplifier housing. Establish a second current path around the housing before disconnecting any cables. Automotive jumper cables are recommended. CAUTION Amplifier electronic components can be damaged by the environment. Close the housing whenever it is left unattended to keep moisture out of the amplifier and to protect the network from RF interference.

    All SEQ-750 and SEQ-862 series equalizers (with and without covers) can be used. While the Flex Max901e trunk amplifiers are designed for 1 GHz operation, they can be configured for use as spares in existing 750 or 870 MHz systems. Refer to Power Supply Configuration beginning on page 5-3 for the appropriate plug-in accessories and locations for 1 GHz or 750/870 operation.

    Soldered-in Jumper Removal Some plug-in locations have soldered-in jumpers next to a plug-in location. If an accessory will be installed in any plug-in location that has a soldered-in jumper, the soldered-in jumper must first be removed completely before installing the accessory. CAUTION Use caution when removing soldered-in jumpers to ensure that no loose wire scraps remain on the RF module printed circuit board.
