Installing or Removing a PMC Module
Before installing a PMC module, check that the PP 110/01x board PMC V(I/O) voltage is
configured to match the requirements of the PMC module. If two PMC modules are fitted, their
V(I/O) requirements must be the same.
CAUTION
If the PP 110/01x is not correctly configured to match the PMC module V(I/O)
requirements, it may result in damage to the module or the PP 110/01x.
Setting the the correct PMC V(I/O) voltage on the PP 110/01x requires the positioning of a
detachable polarizing key for each PMC site, and the setting of a board jumper. Figure 2-10
shows the location of the key for both 5V and 3.3V V(I/O) configurations, and how to fit the PMC
module to the PP 110/01x board. Figure 2-11 shows the location and settings for the PMC
V(I/O) jumper.
NOTE
The positions of the polarizing keys must correspond with the setting of the PMC
V(I/O) jumper.
NOTE
PMC Site 1 does not have provision for a 3.3V polarizing key.
