Installing M8020A Module(s)
The M9505A AXIe chassis and M8020A module(s) will come in separate 
shipments. This section shows how to carefully insert a module in an 
empty slot of an M9505A AXIe chassis. The slots are identified by the slot 
numbers written on the front panel of the chassis.
The procedures in this section are not required if your system is an 
M8020A-BU1 or M8020A-BU2, which have their modules pre-installed.
If you plan to use the M9537A AXIe Embedded Controller as the host 
computer, then you must reserve slot 1 of the chassis for this module’s 
installation. 
• The instrument modules are not hot swappable. You must power 
down the AXIe chassis and host PC before inserting, replacing, or 
removing a module.
• The enclosure surface of the instrument module may become hot 
during use. If you need to remove the module, first power down the 
AXIe chassis, allow the module to cool, and then pull the module out 
of the chassis.
