Keysight M8000 Series of BER Test Solutions Installation Guide 47
Installing Modules 2
 
3 Locate the module insertion/extraction handles at both ends of the 
instrument module. Extend the ends of both handles, by pulling them 
inwards towards each other. Then fully open the handles by pivoting 
them out towards you.
4 Align the module’s PCA board with the guide rails on both ends of the 
M9505A/M9506A AXIe chassis.
5 Push the module into the chassis slot until the leading edges of the 
insertion/extraction latches rest against the front surface of the 
chassis. The insertion/extraction latch handles should be 
perpendicular to the front surface of the chassis (aligned with the 
direction of module insertion). Nudge the module gently inward to 
allow the latches to engage.
6 Using your thumbs, press inward firmly on the insertion/extraction 
handles until the module is seated firmly in the chassis backplane. The 
module front panel should lie flush with the chassis front panel.
7 Push the handles ends towards the edge of the chassis to tuck them 
away.
8 Tighten the retaining screws on either end of the module to ensure the 
ground connection.

After you have installed the module in the chassis, ensure that remaining 
slots have filler panel modules installed.
Do not operate the chassis without filler panels in empty slots. This is 
especially important for the slots on either side of the instrument 
module. This allows proper air flow and cooling, and provides EMI 
shielding for the chassis and installed components. Leaving slots empty 
can increase fan speed, raise ambient noise, overheat components, and 
can cause the module to shut down.
