Appendix A Power Supply Specifications

950 W AC-Input and DC-Input Power Supplies

The 950 W AC-input (PWR-950-AC) and DC-input (PWR-950-DC) power supplies can be installed in
the Catalyst 6503 and Catalyst 6503-E switch chassis only. Due to form factor differences, the 950 W
AC-input and DC-input power supplies cannot be installed in any other Catalyst 6500 series switch
chassis.
The 950 W power supplies (see
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 form
factor is the same for the AC-input and DC-input power supplies.
The AC-input PEM (shown in
power connection on the front of the switch chassis to connect the site power source to the power supply.
You can connect the DC-input power supply to the power source with heavy gauge wiring connected to
a terminal block. The actual wire gauge size is determined by local electrical codes and restrictions.
Note The system (NEBS) ground serves as the primary safety ground for Catalyst 6503 and Catalyst 6503-E
chassis that are equipped with 950 W DC-input power supplies and DC-input PEMs. The DC-input
power supplies for these chassis do not have a separate ground.
The PEMs have an illuminated power switch (AC-input model only), current protection, surge and EMI
suppression, and filtering functions.
