950 W AC-Input and DC-Input Power Supplies

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 router 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 wire gauge size is determined by local electrical codes and restrictions.
The system (NEBS) ground serves as the primary safety ground for Catalyst 6503 and Catalyst 6503-E
Note
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 only), current protection, surge and EMI
suppression, and filtering functions.
