Installing a PMC Module

Installing a PMC Module
Caution
2 - 10
The PPC/PMC-8260/DS1 supports a data bus width of 32/64 bit with a frequency
of 33 or 66 MHz. The supported signaling levels are 3.3V and 5V, therefore, the
PPC/PMC-8260/DS1 can be installed on carrier boards with a signaling level of
3.3V or 5V at their PMC interface.
The front panel of the carrier board provides one or more cutouts to enable the in-
stallation of PMC modules. If the board is shipped without modules installed, the
front panel cutouts are covered by blind panels to ensure proper EMC shielding.
• Be sure to mount only allowed combinations of PPC/PMC-8260/DS1 vari-
ants (see the "Allowed Product Combinations" section on page 2-8). Other-
wise damage to PMC module or carrier board may occur.
• The PPC/PMC-8260/DS1 is not certified for the use with TNV-1 circuits
(Telecommunication Network Voltage-1 circuits). Do not connect E1/T1/J1
lines directly to the PPC/PMC-8260/DS1. Use a Digital Service Unit/Con-
trol Service Unit (DSU/CSU) to eliminate overvoltages.
• Before touching modules or electronic components, make sure that you are
working in an ESD-safe environment.
