5-6 Parallel Gate Amplifier
5.4 Module Installation/Replacement Guidelines
The Power Supply module must be placed in the leftmost slot in the rack. The
remaining slots are used for the PGA modules.
Observe the following guidelines when installing or removing a module:
• Ensure that power to the rack as well as power to the wiring leading to the rack is
off.
• Use the metal guides provided in the rack to facilitate sliding the module into and
out of the rack.
• Use care when inserting a module into the rack to avoid bending the connector
pins.
• Ensure that the module is well seated in the rack. Use the thumbscrews provided
at the top and bottom of the module faceplate to secure the module to the rack.
• The individual modules are not enclosed; therefore, a module's circuit board is
exposed when it is out of the PGA rack. Wear a ground strap and handle the
module by the edges only. When not in use, the module should be stored in an
anti-static bag.
5.5 Installing the PGA Power Supply Module
The following sections describe the input power and fan connections for the PGA
Power Supply module and the cabling between the PGA Power Supply module and
the PMI DC Power Technology module.
!
ATTENTION:Inserting or removing a module or its connecting cables
may result in unexpected machine motion. Turn off power to the PGA
rack before inserting or removing a module or its connecting cables.
ATTENTION:The modules in the Parallel Gate Amplifier rack contain
static-sensitive components. Do not touch the module's circuit board or
the connector on the back of the module. When not in the rack, the
module should be stored in an anti-static bag.
!
ATTENTION: The PGA power supply module operates using AC input
voltage capable of producing severe shock. Make certain that the
external AC supply circuit is turned off before inserting or removing the
module or connecting any wires or cables.
