To replace the housing
1. Disconnect all power to the unit, then remove the RF module and power supply as
described in
RF Module Replacement on page 7-7, Power Supply Replacement on page 7-9,
and Housing Replacement on page 7-13.
2. Beginning at Port 1, use a #2 Phillips screwdriver to loosen the centerseizure screw no
more than two full turns.
3. Loosen the connector back nut and main nut on the external cable connector.
4. Pull the cable with connector main nut straight out of the connector body.
5. Loosen and remove the connector body from the housing cable entry port.
6. Disconnect the remaining ports by repeating Steps 2 through 5.
7. When all cabling is disconnected, close the housing and finger tighten the bolts.
8. Loosen the bolts that secure the housing to the strand, or remove bolts for housings
mounted to EMBs, a pedestal, or a wall.
9. Install the replacement housing in accordance with installation procedures given in
Housing Replacement on page 7-13.
10. Install the RF module and power supply as described in RF Module Replacement on page
7-7, Power Supply Replacement on page 7-9, and Housing Replacement on page 7-13.
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.
CAUTION Centerseizure screws may not be captive. Modules manufactured after June
1999 have either captive boots over these screws or captive screws that cannot be
backed out completely. Do not back out non-captive screws more than two full turns,
because they can fall out into the housing and under the RF module where they can
cause short circuits requiring removal of the RF module and service interruption.
