Supervisor Engines

Supports Supervisor Engine 720, Supervisor Engine 720-10GE, Route Switch Processor 720, Route Switch Processor 720-10GE, and Supervisor Engine 2T.

Note See the software release notes for the minimum software version support information.

Supervisor Engine 720, Supervisor Engine 720-10GE, and Supervisor Engine 2T must be installed in slot 7 and slot 8.

Note Slots not occupied by supervisor engines can be used for modules. See your software release notes for any restrictions on the type of modules supported.

The Supervisor Engine 720, Supervisor Engine 720-10GE, and Supervisor Engine 2T have a built-in switching fabric. Switch Fabric Modules, WS-C6500-SFM and WS-X6500-SFM2 are not supported.

The uplink ports are fully functional on all redundant supervisor engine models when they are in standby mode.

Note In systems with redundant supervisor engines, both the supervisor engines must be the same model and have the same daughter card configurations.

Modules

Supports upto 12 Cisco 7600 series modules.

Slots 1-13 support dual fabric channels.

See your software release notes for specific information on module support. Some Cisco 7600 series modules may have these restrictions:

Not be supported.

Require that you install a specific supervisor engine.

Have chassis slot restrictions.

Require a specific software release level to operate.

Backplane bandwidth

2 Tbps system bandwidth.

80 Gbps per slot for Sup2T.

With SUP 720 and RSP 720, 20Gbps for slots 1-6, 40Gbps for slots 9-13.

Clock and VTT module

Two clock modules provide clocking signals to the ethernet out-of-band channel (EOBC) and the switching bus.

Three voltage termination (VTT) modules provide reference voltage for bus signals.

Fan tray

The chassis supports only one hot-swappable fan tray: FAN-MOD-13SHS(=)

Note The fan tray contains 15 individual fans. Individual fans are not field replaceable; you must replace the entire fan tray in the event of a fan failure.

Per slot cooling capacity of the fan tray is 800W. Fan tray supports automatic mode change for high power consuming cards. Three cooling modes are supported:

Restricted mode - cooling capacity 450W

High Power mode - cooling capacity 600W

Super High Power mode - cooling capacity 800W.

The fan tray is accessible only from the rear of the chassis.

This fan tray contains two status LEDs. (two LEDs: one located on the front of the chassis and one on the fan tray at the rear of the chassis). The LEDs are of these colors:

Red— Indicates one or more individual fans have failed.

Green— Indicates that the fan tray is operating normally.

Power supply

Supports one or two power supplies. The following models are supported:

WS-CDC-2500W (2500 WDC-input power supply).

WS-CAC-3000W (3000 W AC-input power supply).

WS-CAC-4000W-US (4000 W AC-input power supply).

WS-CAC-4000W-INT (4000 W AC-input power supply).

PWR-4000-DC (4000 WDC-input power supply).

PWR-6000-DC (6000 WDC-input power supply).

WS-CAC-8700W-E (8700 W AC-input power supply).

Installed power supplies can be of different ratings. Installed power supplies can also be both AC-input, both DC-input, or one AC-input and one DC-input. Power supplies can be configured in either redundant or combined mode.

All Cisco 7600 series AC-input power supplies requires a single-phase source AC. The source AC can be out of phase between multiple power supplies or multiple AC-power plugs on the same power supply because all AC power supply inputs are isolated.

Supervisor Engine 2T requires a 3000 W or higher power supply to operate.

Note For proper operation of the power supply output fail LED signal, configure systems with single power supplies with a minimum of one fan tray and one supervisor engine. For systems with dual power supplies configure at least one fan tray, one supervisor engine, and one additional module. Failure to meet these minimum configuration requirements could cause a false power supply output fail signal.

Note Installed power supplies can be of different wattage ratings. Installed power supplies can also be both AC-input, both DC-input, or one AC-input and one DC-input. Power supplies can be configured in either redundant or non-redundant mode.



Note If you use AC-input and DC-input power supplies, be sure to consider Failover operation. For example, if you use 4000 W AC and a 2500 W DC power supplies, you need to make sure that the 2500 W DC power supply is capable of supporting the system in the event that the 4000 W AC power supply fails.

Note The status LEDs and captive installation screws are in the same location on the 950 W AC- and DC-input power supplies, in the 1900 W AC- and DC-input power supplies, and in the 2700 W AC- and DC- power supplies.


The Cisco 7603-S router (Figure 1-21), Cisco 7603 router (Figure 1-22), and Cisco 7606 router (Figure 1-23) power supplies have no external connectors but use a power entry module (PEM), located on the front of the chassis, to connect the site power source to the power supply. For more information on the PEM, see the "PEM" section.

The Cisco 7604 router, the Cisco 7606 router, and the Cisco 7606-S with the 2700 W AC power supply (Figure 1-26) use an external power code directly connected to the AC power supply.

The Cisco 7604 router, the Cisco 7606 router, and the 7606-S router with the 2700 W DC input power supply (Figure 1-27) uses an external terminal block on the back side of the chassis for input power connection. The 7606-S router with the 4500 W DC input power supply (Figure 1-28) also uses an external terminal block on the back side of the chassis for input power connection.

Both The AC-input and DC-input and DC-input power supplies support redundancy. When power is removed from one supply, the redundant power feature causes the second supply to produce full power.

For power supply LED descriptions, see the "Environmental Monitoring of the Power Supply" section. For complete power specifications, see "Technical Specifications."

Cisco 7609-S Router Power Supplies


Note For information on installing or replacing a power supply, see the "Removing and Replacing the Power Supply" section.


The Cisco 7609-S router use the following power supplies:

3000 W AC input (WS-CAC-3000W)

4000 W AC input (WS-CAC-4000W-US1) )

4000 W DC input (PWR-4000-DC)

6000 W AC input (WS-CAC-6000W)

6000 W DC input (PWR-6000-DC)

The AC-input power supplies (see Figure 1-29, Figure 1-30, and Figure 1-31) have power cords that allows you to connect each power supply to the site power source. You can connect the DC-input power supplies (see Figure 1-33 and Figure 1-34) 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.

Power Supply Cooling

Each power supply has a minimum one built-in fan. On the Cisco 7603 router, Cisco 7604 router, and the Cisco 7606 router, air enters from the right of the fan and exits through the left. On the Cisco 7609 router, the Cisco 7609-S, and the Cisco 7613 router, air enters the front of the fan (power-input end) and exits through the back; an air dam keeps the airflow separate from the rest of the chassis, which is cooled by the system fan assembly.

The Cisco 7603 router power supplies are self cooling to 77°F (25°C), but require additional airflow provided by the system fan module to operate over the full temperature range. The Cisco 7604 router, Cisco 7606 router, Cisco 7609 router, and Cisco 7613 router power supplies are completely self-cooling.

Load Sharing

When you install and turn on two power supplies, each power supply concurrently provides approximately half of the required power to the system. If one power supply fails, the second power supply immediately assumes full power to maintain uninterrupted system operation. Installing the second power supply enables load sharing and fault tolerance automatically; no software configuration is required.


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.


For information about the power management feature and individual module power consumption, refer to the Cisco 7600 Series Router Supervisor Engine and Route Switch Processor Guide.

Environmental Monitoring of the Power Supply

The environmental monitoring and reporting functions allow you to maintain normal system operation by resolving adverse environmental conditions prior to loss of operation.

The power supplies monitor their own internal temperature and voltages, and in the event of excessive internal temperature, the power supply will shut down to prevent damage. When the power supply returns to a safe operating temperature, it will restart. In the event of an abnormal voltage on one or more outputs of the power supplies, the OUTPUT FAIL LED will light. Substantial overvoltage conditions can lead to a power supply shutdown.

For more information about the environmental monitoring feature, refer to the Cisco 7600 Series Router Supervisor Engine and Route Switch Processor Guide.

PEM


Note For information on installing or replacing a PEM, see the "Removing and Replacing the PEM" section.


The Cisco 7603 router, Cisco 7603-S router, and Cisco 7606 router use PEMs to connect the site power source to the power supply. Table 1-4 list the PEMs and corresponding power upplies for the Cisco 7603 and Cisco 7606 routers.


Note The PWR-2700-AC power supply does not use PEMs.
