Installing and Removing Amplifiers
17.1
Installing QAA Amplifier Modules
1. Hold the amplifier to be installed by the backplate edges.
Do not
handle, push or pull any
of the components on the amplifier (especially not the transformer) as this will damage
those components.
2. Line up the amplifier being installed with the two plastic runners on the card cage and
slide the amplifier back to the point where the amplifier just about touches the pins on
the QMB-5000N/B motherboards.
3. Make sure that the amplifier is square with the motherboard.
4. Gently push the amplifier forward to line up the amplifier connector with the motherboard
pins. Once you have a sense of feel that the amplifier connector and the motherboard
pins are properly lined up, place one thumb on the top edge of the backplate and the
other thumb on the bottom of the backplate and carefully push the amplifier in. You
should hear a slight thud sound when the amplifier is snapped into place.
17.2
Removing the QAA Amplifier Modules
1. Disconnect all cables connected to the amplifier.
Do not
handle, push or pull any of the
components on the amplifier (especially not the transformer) as this will damage those
components.
2. Place the forefinger of one hand on the top inside edge of the front heat sink (the heat
sinks are the two long silver channel-like metal covers opposite the backplate) and the
forefinger of the other hand on the bottom edge of the backplate behind the card cage
frame.
3. Carefully pull and rock the amplifier forward until the amplifier connector is disconnected
from the motherboard pins.
4. Holding the amplifier firmly by the backplate edges, slide the amplifier forward and
completely remove it from the card cage.
ATTENTION:
Improper installation or excessive force will damage the motherboard and
modules being installed or removed.
Note:
If the amplifier connector is not properly lined up with the motherboard pins, or if
excessive force is used, the pins on the motherboard can be damaged.
ATTENTION:
Power should be disconnected before removing and inserting modules.
