RF Module Upgrade
Upgrading an existing 700/800/900 series FlexNet trunk or bridger amplifier to a Flex Max901e
involves the following steps:
■ preparing the power supply
■ removing the existing RF module
■ installing the Flex Max901e RF module
➤ To prepare the power supply for the Flex Max901e RF module upgrade
1. Refer to Table 3.2 on page 3-6 to determine if you can operate a new RF module with an
existing FlexNet power supply.
2. Ensure that you have completed the necessary power supply upgrade requirements before
proceeding.
WARNING Hazardous voltages are present. Use approved safety equipment and
procedures.
CAUTION Arcing between the RF module and centerseizure assemblies will damage
the unit.
Note The Flex Max901e RF module requires a minimum 2.3A power supply and uses
a 12-pin connector. FlexNet 700 series amplifiers used 9-pin connectors. To prepare for
the Flex Max901e RF module upgrade, it may be necessary to use a cable adapter
(9-pin to 12-pin) or upgrade to a new power supply (P/N 122027-05). If a cable adapter
is needed, refer to Cable Adapter (9-pin to 12-pin) Installation on page 3-9.
