Power Connection Guidelines for AC-Powered Systems

When connecting AC-input Power Supply Units (PSUs) to the site power source, observe the guidelines described here.


Warning

Statement 1028—More Than One Power Supply

This unit might have more than one power supply connection. To reduce risk of electric shock, remove all connections to de-energize the unit.

  • Ensure that the AC-input power supply module has a detachable power cord.

  • Each chassis power supply should have a separate, dedicated branch circuit.

    • North America

      • PSU-2KW-ACPI and PSU-2KW-ACPE —Power supply modules require a 20 A circuit.

    • International—Circuits should be sized according to local and national codes.

  • If you are using a 208 or 240 VAC power source in North America, note that such lines are considered hot and the circuit must be protected by a two-pole circuit breaker.


    Warning

    Statement 1005—Circuit Breaker

    This product relies on the building’s installation for short-circuit (overcurrent) protection. To reduce risk of electric shock or fire, ensure that the protective device is rated not greater than:

    • 20 A (North America) and 16 A (Europe) circuit breaker for an AC-input power supply module.


    Warning

    Statement 1022—Disconnect Device

    To reduce the risk of electric shock and fire, a readily accessible disconnect device must be incorporated in the fixed wiring.

  • The source AC outlet must be within 9.84 to 14 feet (3.0 to 4.293 meters) of the system - depending on the length of the power cord, and should be easily accessible.

  • 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 level.

Power Supply Unit Input and Output Ranges

Power Supply Restrictions and Considerations


Warning

Statement 1028—More Than One Power Supply

This unit might have more than one power supply connection. To reduce risk of electric shock, remove all connections to de-energize the unit.


Warning

Statement 1005—Circuit Breaker

This product relies on the building’s installation for short-circuit (overcurrent) protection. To reduce risk of electric shock or fire, ensure that the protective device is rated not greater than:

  • 20 A (North America) and 16 A (Europe) circuit breaker for an AC-input power supply module.

  • 55 A DC-rated circuit breaker for each input of a DC-input power supply module, for safety purposes - irrespective of whether the inputs are power from a single or separate DC sources.

  • Cisco 8711-48Z-M - 40 A DC-rated circuit breaker for each input of a DC-input power supply module, for safety purposes - irrespective of whether the inputs are power from a single or separate DC sources.


Warning

Statement 1022—Disconnect Device

To reduce the risk of electric shock and fire, a readily accessible disconnect device must be incorporated in the fixed wiring.


Warning

Statement 1090—Installation by a Skilled Person

Only a skilled person should be allowed to install, replace, or service this equipment. See statement 1089 for the definition of a skilled person.


Warning

Statement 1091—Installation by an Instructed Person or Skilled Person

Only an instructed person or skilled person should be allowed to install, replace, or service this equipment. See statement 1089 for the definition of an instructed person or skilled person.


Warning

Statement 1073—No User-Serviceable Parts

There are no serviceable parts inside. To avoid risk of electric shock, do not open.

Warning

Statement 1099—Before Connecting to System Power Supply

High touch/leakage current—Permanently connected protective earth ground is essential before connecting to the system power supply.


Warning

Statement 1100—Before Making Telecommunication Network Connection

High touch/leakage current—Permanently connected protective earth ground is essential before connecting to the telecommunication network.

Observe the following guidelines and limitations:

  • Use one type of power supply in a router.

  • The power supply type that is used in the router depends on the type and configuration of the transceivers installed in it.

  • Do not install a mix of AC and DC power supplies in a router.

  • On Cisco 8712-MOD-M and Cisco 8711-32FH-M routers, power redundancy is not supported if either one or both power inputs are at 90V–140V AC.

  • The airflow direction must be the same for all power supply and fan modules in the router.

  • The AC-input power supplies support low-line voltage of 120V (Nominal) and high-line voltage of 220V (Nominal). If you need to change voltage type after installation, disconnect the feed from the power supply before switching the input voltage level.

Connect AC Power to the Chassis


Caution
The chassis relies on the protective devices in the building installation to protect against short circuit, overcurrent, and ground faults. Ensure that the protective devices comply with local and national electrical codes.

Note
We recommend that you occupy both the power supply slots of the fixed port routers with power supplies. In case a power module fails, it is recommended to retain the failed power module in its slot until it is replaced with a new power module. This recommendation ensures that the system airflow is not impacted adversely, which may then result in the overheating of the router and its components.

Warning

Statement 1017—Restricted Area

This unit is intended for installation in restricted access areas. Only skilled, instructed, or qualified personnel can access a restricted access area.


Warning

Statement 1003—DC Power Disconnection

To reduce risk of electric shock or personal injury, disconnect DC power before removing or replacing components or performing upgrades.


Warning

Statement 1046—Installing or Replacing the Unit

To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be made first and disconnected last.

If your unit has modules, secure them with the provided screws.


Warning

Statement 1022—Disconnect Device

To reduce the risk of electric shock and fire, a readily accessible disconnect device must be incorporated in the fixed wiring.

On Cisco 8711-32FH-M and Cisco 8712-MOD-M router, the following power supplies are supported:

  • PSU2KW-ACPI – 2000W AC, port-side intake airflow

  • PSU1100W-ACPI - 1100W, port-side intake airflow

  • PSU1100W-ACPE - 1100W, port-side exhaust airflow


Important
Applicable only to Cisco 8711-32FH-M router:

  • System shall not operate at input voltage: 100-127VAC, 50/60Hz with a single AC power supply condition.

  • System shall operate at input voltage: 100-127VAC, 50/60Hz with dual AC power supply condition.

Note
A dual pole breaker is needed for installation. For determining the recommended breaker size, please adhere to local and national rules and regulations. The breaker size is based on the specifications of the product for the current drawn and the specified voltage level.

Procedure

Step 1

Verify that the AC cable is installed in the correct AC source and outlet type.

Step 2

Attach the AC power cable to the cable connector in the AC power module.

Step 3

Place the cable through the opening in the cable tie.

Step 4

Slide the cable tie toward the plug.

Step 5

Procedure

Step 1

Verify that the correct fuse panel is installed in the top mounting space.

Step 2

Ensure that the DC circuit is powered down (either breaker turned off or fuse pulled) and proper lockout tag out procedures are followed. Use the cable (PID: PWR-2KW-DC-CBL) supplied with the power supply. You can purchase power supply cord separately from Cisco.

Note

 

For Cisco 8711-48Z-M router, the power supply cable is not supplied. You must use a DC PSU connector with Terminal Part No: RNB8-3.7 (or) Equivalent, and 8AWG wire cable.

Step 3

Dress the power according to local practice.

Step 4

Connect the office battery and return cables according to the fuse panel engineering specifications.

Step 5

Insert the DC connector into the DC receptacle on the power supply.
