Installing Modules 2
 
To remove an M8040A module
1 Loosen the retaining screws on both ends of the module until the 
module is completely disengaged to prevent damaging your chassis or 
module.

2 Extend the ends of both module insertion/extraction handles, by 
pulling them inwards towards each other.
Figure 37 Removing an instrument module
3 To remove the module: Open the module insertion/extraction handles 
by pivoting them out towards you. This unseats the module from the 
chassis backplane.
4 Once the module is unseated, use the module insertion/extraction 
handles by pulling directly outward to remove the module from the 
chassis.
The enclosure surface of the module may become hot during use. If you 
need to remove the module, first power down the M9505A/M9506A AXIe 
chassis, allow the module to cool, and then pull the module out of the 
chassis.
