Note The Catalyst 6500 series switches allow you to mix AC-input and DC-input power supplies in the same chassis.
Note Many telco organizations require a –48 VDC power supply to accommodate their power distribution systems. From an operational perspective, the DC-input power supply has the same characteristics as the AC-input version.
Power Supply Compatibility Matrix
Table A-2 lists the compatibility of the power supplies with the Catalyst 6500 switch chassis.
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 Figure A-1) do not connect directly to source AC or source DC 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 form factor is the same for the AC-input and DC-input power supplies.
The AC-input PEM (shown in Figure A-2) and DC-input PEM (shown in Figure A-3) provide an input 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.

Each chassis power supply should have its own dedicated, fused-branch circuit:
– Source AC can be out of phase between multiple power supplies in the same chassis, which means that PS1 can be operating from phase A and PS2 can be operating from phase B. – For high-line operation, the power supply operates with the hot conductor wired to a source AC phase and the neutral conductor wired either to ground or to another source AC phase as long as the net input voltage is in the range of 170 to 264 VAC. – Source AC can be out of phase between AC inputs on power supplies that are equipped with multiple AC inputs, which means that power cord 1 can be plugged into phase A and power cord 2 can be plugged into phase B. |

The 6000 W AC-input power supply, shown in Figure A-16, and the 6000 W DC-input power supply, shown in Figure A-17, share the same form factor as the 1000 W, 1300 W, 2500 W, 3000 W, and 4000 W power supplies.
Note Because of form-factor differences, the 6000 W AC-input and the 6000 W DC-input power supplies cannot be installed in the Catalyst 6503, Catalyst 6503-E, and Catalyst 6504-E switch chassis.

---|---|
2 AC-inputs per power supply. High-line input with power factor correction (PFC) included. Note Power factor correction is a standard feature on all Catalyst 6500 series AC-input power supplies. PFC reduces the reactive component in the source AC current allowing higher power factors (typically 99 percent or better) and lower harmonic current components. |
|
Each power supply input should have its own dedicated, fused-branch circuit:
– Source AC can be out of phase between multiple power supplies in the same chassis, which means that PS1 can be operating from phase A and PS2 can be operating from phase B. – For high-line operation, the power supply operates with the hot conductor wired to a source AC phase and the neutral conductor wired either to ground or to another source AC phase as long as the net input voltage is in the range of 170 to 264 VAC. – Source AC can be out of phase between AC inputs on power supplies that are equipped with multiple AC inputs, which means that power cord 1 can be plugged into phase A and power cord 2 can be plugged into phase B. |
|
The 6000 W power supply can operate at either 2900 W or 6000 W depending on the number of AC power cords attached and the source AC voltage. Note The 6000 W AC-input power supply is limited to 4000 W maximum output when it is installed in a Catalyst 6506, Catalyst 6509, or Catalyst 6509-NEB switch chassis. The power supply is limited to 4500 W maximum output when it is installed in the Catalyst 6509-NEB-A switch chassis. – INPUT 1 and INPUT 2 both connected to low-line (120 VAC nominal) – INPUT 1 connected to high-line (230 VAC nominal); INPUT 2 not connected – INPUT 1 not connected; INPUT 2 connected to high-line (230 VAC nominal) – INPUT 1 connected to high-line (230 VAC nominal); INPUT 2 connected to low-line (120 VAC nominal) – INPUT 1 connected to low-line (120 VAC nominal); INPUT 2 connected to high-line (230 VAC nominal) – INPUT 1 and INPUT 2 both connected to high-line (230 VAC nominal) Note The 6000 W power supply will not power up if you have only one power cord plugged into either INPUT 1 or INPUT 2 and source AC is low-line (120 VAC nominal). |

8700 W AC-Input Power Supply
Catalyst 6500 series switch support for the 8700 W AC-input (WS-CAC-8700W-E) power supply along with any power supply output restrictions are listed in Table A-37 .
|
|
---|---|
The 8700 W AC-input power supply, shown in Figure A-18, shares a similar, but not identical, form-factor as the 1000 W, 1300 W, 2500 W, 3000 W, 4000 W, and 6000 W power supplies.
Note Because of the form-factor difference, when you install an 8700 W power supply in a Catalyst 6506, Catalyst 6509, or Catalyst 6509-NEB chassis you must relocate the system ground connection from the chassis ground pad connection to the two system ground studs located on the 8700 W power supply faceplate. Installing an 8700 W power supply in the other Catalyst 6500 series chassis does not require that you move the chassis system ground connection to the power supply.
The 8700 W power supply cannot be installed in the Catalyst 6503, Catalyst 6503-E, and Catalyst 6504-E switch chassis.

Remote Power Cycling Feature
The 8700 W power supply is equipped with a remote power cycling feature that allows you to remotely turn on or turn off the power supply through an external relay controller box. Figure A-19 shows a typical remote power on/off setup. A three-position terminal block and a switch, located on the lower right quadrant of the power supply faceplate (see Figure A-18), provide the interface to the external relay controller box.
Figure A-19 Remote Power On/Off Feature Components
Terminal Block
The terminal block has three contacts labeled 1, 2, and 3. Two control wires from an external relay controller box attach to either positions 1 and 2 or positions 2 and 3. Positions 1 and 2 are used when the relay controller box contains a normally-open (NO) type of relay. Positions 2 and 3 are used when the relay controller box contains a normally-closed (NC) type of relay.
Relay Controller Box Switch
The relay controller box switch, located next to the terminal block, allows you to match the power supply power control signal’s active state with the type of relay contained in the external relay controller box (either a normally-open type of relay or a normally-closed type of relay).
Ferrite Bead
A plastic bag containing one ferrite bead and two 4-inch plastic ties is included with the 8700 W power supply AC power cords. The ferrite bead is a passive device that limits high-frequency interference on interface and control cables, and is only required when you install the remote power-cycling feature that is supported by the 8700 Watt power supply. The ferrite bead is installed on the two control wires that come from the relay controller box to the terminal block on the 8700 W power supply. The ferrite bead should be installed as close as possible to the power supply terminal block for the bead to be effective. You do not need the ferrite bead for 8700 Watt power supply installations that do not include the remote power-cycling feature. If you need to install the ferrite bead, refer to Installing the Ferrite Bead.
Remote Power-Cycling Operation
This feature allows you to remotely power cycle the Catalyst 6500 series switch using any appropriate third-party relay controller. This eliminates the need for you to have access to the supervisor engine console or CLI to control power cycling. Table A-40 lists the relay controller box relay type, the corresponding power supply terminal block positions, and a description of the power-cycling operation.

Power Supply Redundancy
Catalyst 6500 series switching modules have different power requirements. Depending upon the wattage of the power supply, certain switch configurations might require more power than a single power supply can provide.
The Catalyst 6500 series switches can use two power supplies to function in either combined or redundant mode. The following table explains the differences between the two modes.
Although the power management feature allows you to supply power to all installed modules with two power supplies, redundancy is not supported in this configuration. Redundant and combined power configurations are summarized in Table A-43 . The effects of changing the power supply configurations are summarized in Table A-44 .
Note For proper load-sharing operation in a redundant power supply configuration, you must install two modules in the chassis. If you fail to install two modules, you might receive spurious OUTPUT FAIL indications on the power supply.
Note In systems that have two different sized power supplies installed, you may not have true redundancy. If the larger wattage power supply fails, the smaller wattage power supply might not be able to handle the entire load by itself.
When running redundant 4000 W, 6000 W, or 8700 W power supplies in Catalyst 6506 and Catalyst 6509 non-E series systems, if you remove the power supply in bay 1, the total system power will be reduced to 2940 W (70 A at 42 VDC) after 180 seconds (3 minutes). You can avoid this reduction in the total system power by leaving the power supply in bay 1, even in a powered down state.
If the total system power usage is greater than 2940 W, the following scenario will apply if a 4000 W, 6000 W, or a 8700 W power supply is removed from bay 1 (these scenarios are specific to only these three power supplies running in redundant mode in either the Catalyst 6506 or Catalyst 6509 non-E series systems).
- If the power supplies in bay 1 and bay 2 are running in redundant mode, the total system power will be 4000 W.
- If power supply 1 is running and you power off or remove power supply 2, the total system power will be 4000 W. The system will issue a normal power supply 2 down/remove indication warning.
- If you power down power supply 1 while power supply 2 is operating, the system will issue a normal power supply 1 down indication warning with another warning asking the user not to remove power supply 1. If power supply 1 is left in the system, even if it is powered off, the total system power will be 4000 W.
- If you remove power supply 1 from the system, a major alarm will be issued to warn that the total system power will be reduced to 2940 W and that any modules or PoE devices that cause the system to exceed 2940 W will power down in 180 seconds (3 minutes). If you insert a replacement power supply 1 in the 180-second timeframe, no action will be taken.
Note In systems that are equipped with two power supplies, if one power supply fails and the other power supply cannot fully power all of the installed modules, system power management will shut down devices in the following order:
- Power over Ethernet (PoE) devices— The system will power down PoE devices in descending order, starting with the highest numbered port on the module in the highest numbered slot.
- Modules—If additional power savings are needed, the system will power down modules in descending order, starting with the highest numbered slot. Slots containing supervisor engines or Switch Fabric Modules are bypassed and are not powered down.
This shut down order is fixed and cannot be changed.
You can change the configuration of the power supplies to redundant or combined at any time. If you switch from a redundant to a combined configuration, both power supplies are enabled (even a power supply that was disabled because it was of a lower wattage than the other power supply). If you change from a combined to a redundant configuration, both power supplies are initially enabled, and if they are of the same wattage, they remain enabled. If they are of different wattage, a syslog message displays and the lower wattage supply is disabled.
For additional information about the power management feature and individual module power consumption, refer to your software configuration guide.
