Cisco 7609 Internet Router

System Features

Cisco 7600 Internet Router Components

The Cisco 7609 Internet Router delivers optical WAN and MAN networking with a focus on line-rate delivery of high-touch IP services at the edge of service providers networks. Service providers can "service enable" their networks at optical speeds, enabling them to differentiate their service offerings for competitive advantage.

The Cisco 7609 Internet Router supports the following features:

30 Mpps forwarding processor and up to 512 MB DRAM for Internet routing

Up to two distributed Parallel Express Forwarding (PXF) IP services processors on each Optical Services Module (OSM) for flexible IP service implementation

High-touch, line-rate IP services at 6 Mpps per slot:


Hierarchical Traffic Shaping

Destination Sensitive Services (accounting, billing, and QoS)

The ability to monitor service levels delivered to customers under service level agreements (SLAs)

Wide range of WAN and MAN interfaces providing DS0 through OC-48 (using the FlexWAN module)

Compatibility with the Catalyst 6000 family LAN interfaces offering 10 Mbps Ethernet to 1 Gbps

Cisco 7609 Internet Router

The Cisco 7609 Internet Router chassis has nine vertical slots that are numbered from right to left. (See Figure 1-1.)

Slot 1 is reserved for the supervisor engine, which provides switching, local and remote management, and multiple gigabit uplink interfaces.

Slot 2 can contain an additional redundant supervisor engine, which can act as a backup if the first supervisor engine fails. If a redundant supervisor engine is not required, slot 2 is available for an OSM or other supported Catalyst 6000 family modules.

For a detailed description of supervisor engine operation in a redundant configuration, refer to the Cisco 7600 Series Internet Router Software Configuration Guide.

Figure 1-1 Cisco 7609 Internet Router

The Cisco 7609 Internet Router supports the following:

A Supervisor Engine 2 with MSFC2 and a PFC2, and an optional redundant Supervisor Engine 2 with MSFC2 and a PFC2. Each supervisor engine has two Gigabit interface uplinks.

Note The uplink ports are fully functional on the redundant supervisor engine in standby mode.

Note Both supervisor engines in a single chassis must be completely identical.

Backplane bandwidth scalable up to 256 Gbps when using the Switch Fabric Module (WS-C6500-SFM)

Up to eight additional OSMs or Catalyst 6000 family modules

Hot-swappable fan assembly and modules

Redundant AC-input or DC-input power supplies

The Cisco 7609 Internet Router has these redundancy features:

Ability to house two hot-swappable supervisor engines

Ability to house two fully redundant, AC-input or DC-input, load-sharing power supplies

Note In certain configurations, the power supplies are not fully redundant.

A hot-swappable fan assembly containing multiple fans

Redundant backplane-mounted clock modules

Redundant backplane-mounted voltage termination (VTT) modules

Component Hot Swapping

You can hot swap all modules (including the supervisor engine if you have a redundant supervisor engine) and fans. You can add, replace, or remove modules without interrupting the system power or causing other software or interfaces to shut down.

Note Although the FlexWAN module supports hot swapping, individual port adapters do not. To replace port adapters, you must first remove the FlexWAN module from the chassis and then install or replace port adapters as required.

Cisco 7600 Internet Router Components

This section describes the major hardware components for the Cisco 7609 Internet Router.

Fan Assembly

The system fan assembly provides cooling air for the supervisor engine and the switching modules. The fan assembly is located in the chassis. Figure 1-2 shows the direction of airflow into and out of the Cisco 7609 Internet Router. Sensors on the supervisor engine monitor the internal air temperatures. If the air temperature exceeds a preset threshold, the environmental monitor displays warning messages.

If an individual fan within the assembly fails, the FAN STATUS LED turns red. To replace a fan assembly, see the "Removing and Replacing the Fan Assembly" section on page 5-12.

Note Refer to the Cisco 7600 Series Internet Router Software Configuration Guide for information on environmental monitoring.

Figure 1-2 Cisco 7609 Internet Router Internal Airflow

Power Supplies

The Cisco 7609 Internet Router power supplies are available in two power ratings:

2500W—AC and DC input (WS-CAC-2500W and WS-CDC-2500W)

4000W—AC input only (WS-CAC-4000W-US1 or WS-CAC-4000W-INT)

All power supplies have the same form factor.

The Cisco 7609 Internet Router supports redundant AC-input and DC-input power supplies.

Each power supply has an individual power switch.

The AC-input power supply (see Figure 1-3) has a detachable power cord (except for the WS-CAC-4000W) that allows you to connect each power supply to the site power source. You can connect the DC-input power supply (see Figure 1-4) to the power source with heavy gauge wiring connected to a terminal block.

Note The power cord is not shown in Figure 1-3.

Both AC-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.

Note If you run the 2500W power supply at the low range input (100 to 120VAC), it is not redundant in a fully populated Cisco 7609 Internet Router.

For complete power specifications, see Appendix A, "Technical Specifications."

Figure 1-3 AC-Input Power Supply

Figure 1-4 DC-Input Power Supply

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 Internet Router Software Configuration 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. 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.

The power supply front panel LEDs are described in Table 1-2.

For more information about the environmental monitoring feature, refer to the Cisco 7600 Series Internet Router Software Configuration Guide.

Table 1-2 Power Supply Front Panel LEDs



AC-input power supplies:

Green when the input voltage is OK (85 VAC or greater)

Off when the input voltage falls below 70 VAC or if the power supply shuts down

DC-input power supplies:

Green when the input voltage is OK (-40.5 VDC or greater)

Off when the input voltage falls below -33 VDC or if the power supply shuts down


Green when the power supply fan is operating properly


Red when there is a problem with one or more of the DC-output voltages of the power supply

Power Supply Fan Assembly

The power supplies have a built-in fan; 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.

To replace a power supply, see the "Removing and Replacing the Power Supply" section on page 5-2.
