S Limited Power on PMC Modules and RTMs
The blade does not provide an extra fuse for PMC modules and RTMs.
PMC modules and RTMs used together with the blade have to be qualified
according to the following standards: IEC 60950−1, EN 60950−1, UL 60950−1,
CAN/CSA C22−2 No 60950−1
S Excession of blade‘s power consumption
Exceeding the maximum combined power dissipation of installed PMC modules
may damage the blade.
a
Make sure that the combined power dissipation of installed PMC modules on the
3.3V and 5V rail does not exceed 60W.
S PMC Module Malfunctioning
Processor PMC modules (as defined in ANSI/VITA 32−2003) can be operated in two
different modes: monarch and non−monarch mode.
a
Make sure to operate any installed processor PMC modules (as defined in
ANSI/VITA 32−2003) only in non−monarch mode.

S Damage of Installed Hard Disk
If PPMC/270 or PPMC/280 modules are installed into PMC slot 1 or 2, the heat
radiated by the heat sink of theses PMC modules heats up an installed hard disk
that may be installed at the same time.
a
If PPMC/270 or PPMC/280 modules are installed into PMC slot 1 or 2, make sure not
to have a hard disk installed at the same time.
a
S Damage of Rear Transition Module and Blade
The ACC/ARTM−717 was designed to be used in conjunction with PPMC/270 or
PPMC/280 modules modules installed on the blade at the same time.
In order to avoid damage of the blade or RTM, only use the ACC/ARTM−717 in
conjunction with PPMC/270 or PPMC/280 modules.
