Power Requirements for Firepower 8000 Series Devices

Warnings and Cautions

This document contains both warnings and cautions. Warnings are safety related. Failure to follow warnings may lead to injury or equipment damage. Cautions are requirements for proper function. Failure to follow cautions may result in improper operation.


Caution The intra-building ports of the equipment or subassembly are suitable for connection to intra-building or exposed wiring or cabling only. The intra-building ports of the equipment or subassembly must not be metallically connected to interfaces that connect outside the plant (OSP) or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of the primary protectors is not sufficient protection to connect these interfaces metallically to OSP wiring.

Static Control


Caution Electrostatic discharge control procedures, such as using grounded wrist straps and an ESD work surface, must be in place before unpacking, installing, or moving the appliance. Excessive electrostatic discharges can damage the appliance or cause unintended operation.

Firepower 81xx Family Appliances

This section describes the power requirements for:

  • Firepower 8120, 8130, and 8140 (CHAS-1U-AC, CHAS-1U-DC, or CHAS-1U-AC/DC)

These appliances are suitable for installation by qualified personnel in network telecommunication facilities and locations where the National Electric Code applies.

Cisco recommends that you save the packing materials in case a return is necessary.

For more information, see the following sections:

  • See AC Installation for circuit installation, voltage, current, and frequency range, and power cord information.
  • See DC Installation for circuit installation, voltage, current, ground references, terminals, breaker requirements, and minimum wire size.
  • See Grounding/Earthing Requirements for bonding locations, recommended terminals, ground wire requirements, and DC supplies.

AC Installation

The Firepower System must be installed in accordance with the requirements of Article 250 of NFPA 70, National Electric Code (NEC) Handbook, and local electrical codes.


Caution Do not connect DC power to AC supplies.

Separate circuits are required to create redundant power sources. Use an uninterruptible or battery-backed power source to prevent power status issues or power loss due to input line power glitches.

Supply sufficient power to each power supply to run the entire appliance. The voltage and current ratings for each supply are listed on the label on the appliance.

Use an external Surge Protection Device at the input of the network equipment where the Firepower System is to be installed.

Separate Circuit Installation

If separate circuits are used, each one must be rated the full rating of the appliance. This configuration provides for circuit failure and power supply failure.

Example: Each supply is attached to a different 220V circuit. Each circuit must be capable of supplying 5A, as stated on the label.

Same Circuit Installation

If the same circuit is used to feed both supplies, then the power rating of one supply applies to the whole box. This configuration only provides protection from a power supply failure.

Example: Both supplies are attached to the same 220V circuit. The maximum draw from this circuit would be 5A, as stated on the label.

AC Voltage

The power supplies will work with these voltages: 100VAC to 240VAC nominal (85VAC to 264VAC maximum). Use of voltages outside this range may cause damage to the appliance.

AC Current

The labeled current rating for each supply is: 5.2A maximum over the full range, per supply 2.6A maximum for 187VAC to 264VAC, per supply. Appropriate wire and breakers must be used to reduce the potential for fire.

Frequency Range

The frequency range of the AC power supply is 47 Hz to 63 Hz. Frequencies outside this range may cause the appliance to not operate or to operate incorrectly.

Power Cords

The power connections on the power supplies are IEC C14 connectors and they will accept IEC C13 connectors. A UL-recognized power cord must be used. The minimum wire gauge is 16 AWG. The cords supplied with the appliances are 16 AWG, UL-recognized cords with NEMA 515P plug. Contact the factory about other power cords.

DC Installation

Separate circuits are required to create redundant power sources. Use an uninterruptible or battery-backed power source to prevent power status issues or power loss due to input line power glitches.


Caution Do not connect AC power to DC supplies.

Supply sufficient power to each power supply to run the entire appliance. The voltage and current ratings for each supply are listed on the label on the appliance.

Use an external Surge Protection Device at the input of the network equipment where the Firepower System is to be installed.

Separate Circuit Installation

If separate circuits are used, each circuit must be rated to the full rating of the appliance. This configuration provides for circuit failure and power supply failure.

Example: Each supply is attached to a different –48VDC circuit. Each circuit must be capable of supplying 20A, as stated on the label.

Same Circuit Installation

If the same circuit is used to feed both supplies, then the power rating of one supply applies to the whole box. This configuration only provides protection from a power supply failure.

Example: Both supplies are attached to the same –48VDC circuit. The maximum draw from this circuit would be 20A, as stated on the label.


Caution Use of this optimization requires that the power cords are rated for the full rating for each supply.

DC Voltage

The power supplies will work with these voltages:

  • -48VDC nominal referenced to RTN
  • -40VDC to -72VDC maximum

Use of voltages outside this range may cause damage to the appliance.

DC Current

11A maximum, per supply

Ground Reference

The DC power supplies are fully isolated from the ground reference.

Recommended Terminals

Power is connected to the DC supplies through screw terminals. Terminals must be UL approved. Terminals must have a hole supporting an M4 or a #8 screw. The maximum width of the terminal is 8.1mm (0.320”). A representative spade terminal for 10-12 gauge wire is Tyco 325197.

Breaker Requirements

A breaker sufficient to carry the rated current at the rated voltage must be provided. The circuit breaker must meet the following requirements:

  • UL Recognized
  • CSA Approved (Recommended)
  • VDE Approved (Recommended)
  • Support the maximum load (20A)
  • Support the installation voltage (-40V to -72VDC, as required by the power supply)
  • Rated for DC use

A recommended breaker is: Airpax IELK1-1-72-20.0-01-V. The terminal option used will depend on the installation. This breaker is a single pole, 20A breaker with a DC rating of 80V. It is listed as having a long delay. Information about this breaker can be found at http://www.airpax.net/site/utilities/eliterature/pdfs/ial.pdf.

Minimum Wire Size Requirements

Power feeds with three wires (one circuit) per raceway may use 12 AWG wire. Power feeds with more than one circuit per raceway must use 10 AWG wire. Note that the two separate feeds for the redundant supplies are two circuits and must use 10 AWG wire.

Grounding/Earthing Requirements

The Firepower System must be grounded to the Common Bonding Network.

Bonding Locations

Ground bonding locations are provided on the rear of the chassis. M4 studs are provided. Outside-toothed lock washers are provided for attaching ring terminals. A standard ground symbol is available by each stud.

The following illustration indicates the bonding locations on the 1U chassis.

 

Recommended Terminals

You must use UL-Approved terminals for the ground connection. Ring terminals with a clearance hole for 4mm or #8 studs may be used. For 10-12 AWG wire, Tyco 34853 is recommended. This is a UL-approved, ring terminal with a hole for a #8 stud.

Ground Wire Requirements

The ground wire must be sized sufficiently to handle the current of the circuit in case of a single fault. The size of the ground wire should be equal to the current of the breaker used to protect the circuit. For AC circuits, see AC Current. For DC currents, see DC Current.

Bare conductors must be coated with antioxidant before crimp connections are made. Only copper cables can be used for grounding purposes.

DC Supplies

The DC power supplies have additional ground connections on each supply. This allows the hot-swappable supply to be connected to power, return and ground so that it may be safely inserted. This ground lug must be attached.

It is a M4 screw with an outside-toothed lock washer screw.

The ground wire should be sized to match the breaker for the circuit.
