1400 W AC-Input Power Supply
1400 W AC-Input Power Supply
The 1400 W AC-input power supply (PWR-1400-AC) can be installed in the Catalyst 6503 switch and
Catalyst 6503-E switch chassis only. Due to form factor differences, the 1400 W AC-input power supply
cannot be installed in any other Catalyst 6500 series switch chassis.
The 1400 W power supplies (see Figure A-7) do not connect directly to source AC but use power entry
modules (PEMs), located on the front of the Catalyst 6503 and Catalyst 6503-E switch chassis, to
connect the site power source to the power supply located in the back of the chassis.
The AC-input PEM (PEM-20A-AC+) (shown in Figure A-8) provides an input power connection on the
front of the router chassis to connect the site power source to the power supply.
The PEMs have an illuminated power switch, current protection, surge and EMI suppression, and filtering
functions.
