Installing the MVME240x Hardware
The following paragraphs discuss installing PMCs onto the MVME240x
installing PMCspan modules onto the MVME240x, installing the 
MVME240x into a VME chassis, and connecting an optional system 
console terminal. 
ESD Precautions
Motorola strongly recommends that you use an antistatic wrist strap and a 
conductive foam pad when installing or upgrading a system. Electronic 
components, such as disk drives, computer boards, and memory modules, 
can be extremely sensitive to Electro-Static Discharge (ESD). After 
removing the component from the system or its protective wrapper, place 
the component flat on a grounded, static-free surface (and in the case of a 
board, component side up). Do not slide the component over any surface.
If an ESD station is not available, you can avoid damage resulting from 
ESD by wearing an antistatic wrist strap (available at electronics stores) 
that is attached to an unpainted metal part of the system chassis.
PMCs
PCI mezzanine card (PMC) modules mount on top of the MVME240x 
module, and/or on a PMCspan. Refer to Figure 1-3 and perform the 
following steps to install a PMC on your MVME240x module. This 
procedure assumes that you have read the user’s manual that came with 
your PMCs. 
1. Attach an ESD strap to your wrist. Attach the other end of the ESD 
strap to the chassis as a ground. The ESD strap must be secured to 
your wrist and to ground throughout the procedure.
2. Perform an operating system shutdown. Turn the AC or DC power 
off and remove the AC cord or DC power lines from the system. 
Remove chassis or system cover(s) as necessary for access to the 
VMEmodules.
