Site Requirements

This section provides site power requirements for the Cisco 7600 series routers. You should verify the site power prior to installing the router. Power requirements vary for each router; ensure that you verify the site power for the type of router you are installing.

For EMI recommendations, refer to the Site Preparation and Safety Guide.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing ESD damage:

Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

Connect the equipment end of the strap to an unfinished chassis surface.

When installing a component, use any available ejector levers or captive installation screws toproperly seat the bus connectors in the backplane or midplane. These devices prevent accidentalremoval, provide proper grounding for the system, and help to ensure that bus connectors areproperly seated.

When removing a component, use any available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.

Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.

Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.

Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Never attempt to remove the printed circuit board from the metal carrier.


Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).

Environmental Requirements

Insure adequate spacing between racks using the information in Table 2-2. Keep all of the vents clear of obstructions, including dust and foreign conductive material, and away from the exhaust ports of other equipment.

Heat dissipation is an important consideration for sizing the air-conditioning requirements for an installation. The power and heat associated with a Cisco 7600 series router varies based upon these considerations:

Power supply type

Module types and quantities

Average traffic levels

Unless otherwise noted, the information in Table 2-3 through Table 2-19 assumes worst-case conditions (with GBICs and port adapters installed, if applicable), so typical numbers are approximately 30 percent below the numbers listed here. See Table 2-20 for a sample calculation of a router configuration.

This section provides the power and heat numbers for the Cisco 7600 series chassis and modules. The following power requirements and heat dissipation tables are provided:

Chassis and fan trays—Table 2-3

Supervisor engines—Table 2-4

Policy Feature Cards (PFCs)—Table 2-5

Distributed Forwarding Cards (DFCs)—Table 2-6

Switch fabric modules—Table 2-7

10-Gigabit Ethernet modules—Table 2-8

Gigabit Ethernet modules—Table 2-9

10/100/1000 Ethernet modules—Table 2-10

Fast Ethernet switching modules—Table 2-11

10/100 Ethernet switching modules—Table 2-12

10BASE Ethernet switching modules—Table 2-13

FlexWAN and Enhanced FlexWAN modules—Table 2-14

Service modules—Table 2-15

SPA Interface Processors (SIPs)—Table 2-16

Ethernet service cards—Table 2-17

Optical service modules (OSMs)—Table 2-18

Miscellaneous cards—Table 2-19


Note Module power is the output from the power supply (internal to the system). The AC-input power is the input from the outlet to the power supply. The percentage difference between the two values is the efficiency of the power supply.

Note The module power values are based on 42 VDC. Power is distributed to each slot in the chassis from the power supply's 42 VDC output. Each module has DC-to-DC power supplies that convert the 42 VDC into +2.5 VDC, +3.3 VDC, and +5 VDC to power the module. The 42 VDC is independent of the power supply's input voltage, either 110 VAC or 220 VAC.

Power Requirements


Warning Read the installation instructions before connecting the system to the power source.

Follow these requirements when preparing your site for the router installation:

The redundant power option provides a second, identical power supply to ensure that power to the chassis continues uninterrupted if one power supply fails or input power on one line fails.

In systems configured with the redundant power option, connect each of the two power supplies to a separate input power source. If you fail to do this, your system might be susceptible to total power failure due to a fault in the external wiring or a tripped circuit breaker.

To prevent a loss of input power, be sure that the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and breakers.

In some systems, you might use an uninterruptible power supply (UPS) to protect against power failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems like the Cisco 7600 series router, which can have substantial current draw fluctuations due to bursty data traffic patterns.

Use the information in Table 2-3 through Table 2-19 to estimate the power requirements and heat dissipation of a Cisco 7600 series router based on a given configuration of the router. Table 2-20 provides a sample calculation. Determining power requirements might be useful for planning the power distribution system needed to support the router.

Power Connection Guidelines

This section provides the guidelines for connecting the Cisco 7600 series router AC and DC power supplies to the site power source.

AC-Powered Systems

Basic guidelines for AC-powered systems include the following:

Each chassis power supply should have its own dedicated branch circuit.

The circuit must be protected by a dedicated two-pole circuit breaker. For North America, the circuit breaker should be rated as follows:

15A for the 950 W power supply

15A or 20A for the 1400 W power supply

20A for the 1900 W power supply

20A for the 2700 W power supply

20A for the 3000 W power supply

30A for the 4000 W power supply.

20A for the 6000 W power supply (one for each of two inputs)

For everywhere else, the circuit breaker should be sized according to the power supply input rating and local or national code requirements.

The AC power receptacles used to plug in the chassis must be the grounding type. The grounding conductors that connect to the receptacles should connect to protective earth ground at the service equipment.


Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Warning The plug-socket combination must be accessible at all times because it serves as the main disconnecting device.

Warning This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations.

Table 2-21 lists the AC-input power cord options, specifications, and Cisco product numbers for the 950 W, 1400 W, 1900 W, 3000 W, 4000 W, and the 6000 W AC-input power supplies. Table 2-21 also references power cord illustrations.

DC-Powered Systems

Basic guidelines for DC-powered systems include the following:

Each chassis power supply should have its own dedicated input power source. The source must comply with the safety extra-low voltage (SELV) requirements in the UL 60950, CSA 60950, EN 60950, IEC 60950 standards.

The circuit must be protected by a dedicated two-pole circuit breaker. The circuit breaker should be sized according to the power supply input rating and local or national code requirements.

The circuit breaker is considered the disconnect device and should be easily accessible.

The system ground is the power supply and chassis ground.


Caution Do not connect the DC-return wire to the system frame or to the system grounding equipment.
