Installation of a PMC Module
The PMC modules are mounted to the TPCE260 prior to installation into the system.
If the PMC has a front panel, first remove the cover from the PMC front panel cut-out of the TPCE260. Install
the PMC at an angle so that the PMC front panel penetrates the PMC front panel cut-out. Then rotate down to
mate with the PMC connectors on the TPCE260. If the PMC has no front panel, simply plug in the PMC, and
leave the cover in the PMC front panel cut-out of the TPCE260.
After the PMC module has been installed, it can be mounted on the TPCE260 using the mounting screws that
come with the PMC module. There are four screw mounting locations, two at the PMC front panel and two at
the standoffs near the PMC bus connectors.
Before installing a PMC module, be sure that the power supply for the TPCE260 is turned off.
The components are Electrostatic Sensitive Devices (ESD). Use an anti-static mat connected to
a wristband when handling or installing the components.
WARNING!!!
Be sure that the TPCE260 PCI bus signaling voltage (V_I/O) configuration matches the TPCE260
PMC slots keying pin configuration.
Be sure that the used PMC modules match the TPCE260 PCI bus signaling voltage and PMC slot
keying pin configuration.
If PMC modules are plugged into a PCI environment where the PCI signaling voltage does not
match, damage to the equipment could occur, voiding product warranties.
