Installing a PMCspan-001 or PMCspan-002
The difference between the PMCspan -001 and -002 is that the PMCspan-
001 mounts on top of the 2600/2700/3600/4600 series VME processor
module and The PMCspan-002 mounts onto an MVME2300 series
processor module. To upgrade or install a PMCspan, refer to Figure 2-2
(PMCspan-001) or Figure 2-3 (PMCspan-002) and proceed as follows:
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 while you are performing the installation
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
VME module card cage.
!
Caution
Inserting or removing modules with power applied may result
in damage to module components.
!
Warning
Dangerous voltages, capable of causing death, are present in
this equipment. Use extreme caution when handling, testing,
and adjusting.
3. Carefully remove the VME processor module from the VMEbus
card slot and lay it flat, with connectors P1 and P2 facing you.
!
Caution
Avoid touching areas of integrated circuitry; static discharge
can damage these circuits.
4. Install the PMC adapter modules on the PMCspan and VME
processor module. Refer to Installing PMC Adapters on page 2-2
and the installation instructions that are supplied with the PMC
adapters.
