Calculate Power Requirements for a PTX10008

Use the information in this topic to calculate power requirements of your PTX10008 configuration and the number of power supplies required for different PTX10008 router configurations.

Caution

To ensure adequate power and to avoid raising a power alarm, we recommend that you maintain n +1 power supplies in JNP10008-SF configurations at all times. Replace failed power supplies immediately to prevent unexpected failures.

If a new line card is installed in an operational router, power management does not power on the line card if the increased power demand exceeds the total available power, including redundant power. If redundant power is used to power on the line card, a minor alarm is raised, which becomes a major alarm in five minutes if the condition is not corrected.

Note

The calculations in this topic represent the maximum power requirements that you need to budget for your PTX10008 router configuration. The actual power consumption of your router will be less than the calculated results shown here and will vary based on the hardware and software configuration of your router, the amount of traffic passing through the line cards, and environmental variables such as room temperature.

Before you begin these calculations:

This topic describes these tasks:

  1. Calculate the Power Consumption of Your PTX10008 Configuration

  2. Calculate the Number of Power Supplies Required for Your PTX10008 Configuration

Calculate the Power Consumption of Your PTX10008 Configuration

Use the following procedure to determine the maximum power you need to supply to the router. To calculate maximum system power consumption, you first determine the combined maximum internal power requirements of all the router components and then divide this result by the power supply output power.

To calculate maximum system power consumption:

  1. Determine the maximum power consumption of the base chassis components (that is, the components other than the line cards). Use Table 2 if your router is configured as either the standard base or redundant configuration.

  2. Calculate the maximum internal power consumption of the entire router by adding in the power requirements of each line card. See Table 3 for a chart of the power needed for line cards.

    Note: * The PTX10K-LC1201-36CD power numbers do not include the power draw of optical transceivers. See the Hardware Compatibility Tool for further information.

    Note

    The PTX10K-LC1104 line card is designed to comply with NEBS regulations on the PTX10008 Packet Transport Router when these routers are used in typical configurations. In a typical configuration, a PTX10008 router supports up to eight line cards, with up to four PTX10K-LC1104 line cards in any of the eight slots.

    For example, for a PTX10008 with five PTX10K-LC1102 line cards and three PTX10K-LC1101 line cards, the maximum power consumption is:

    = 5 (power consumed by PTX10K-LC1102 in watts) + 3 (power consumed by PTX10K-LC1101 line cards in watts)

    = 5 (675 W) + 3 (1150 W)

    = (3375 W + 3450 W)

    = 6825 W

  3. Add the power consumption from Step 1 and the total line card consumption from Step 2.

    To continue from the previous example, add the wattage from five PTX10K-LC1102 and three PTX10K-LC1101 cards to a premium configuration.

    (6825 W) + (2710 W)

    = 9535 W required

Calculate the Number of Power Supplies Required for Your PTX10008 Configuration

Use this procedure to calculate the number of power supplies required by your router configuration. The minimum power configuration for PTX10008 routers is three power supplies. However, using the calculated minimum power configuration does not prevent the system from raising a power alarm. If you are running the router in a JNP10008-SF switch fabric configuration, you must configure your router for n+1 power supplies to ensure you do not log power alarms.

To calculate the number of power supplies required for your minimum router configuration:

  1. Determine the power available from the power supplies. Table 4 shows the power available for installed power supplies.Note

    DC systems are supported only in the redundant configuration.

    Note

    The HVAC/HVDC power supply, JNP10K-PWR-AC2, has a set of DIP switches on the faceplate that allows you to configure the power supply for either high power (30 A) or low power (20 A) input mode. If any JNP10K-PWR-AC2 power supply is set to 20 A, then the power budget for all power supplies installed in the system becomes 20 A, regardless of whether other power supplies are set at 30 A. This design helps prevent overloading of the power supply that is set to 20 A. See Table 5 for details about setting the DIP switches and available power.

  2. Determine the total power required for your configuration with line cards installed. The total power available to the chassis is calculated by dividing the wattage needed by the power rating, and then rounding up.

    In the previous examples, we calculated that a premium PTX10008 AC system would require 9535 W with five PTX10K-LC1102 and three PTX10K-LC1101 line cards. In this example, we calculate the total power available for the 2700 W JNP10K-PWR-AC power supplies:

    = (9535 W) / (2700 W)

    = 3.5

    Round up the result to 4 AC power supplies to determine the minimum power level.

    Caution

    The minimum power level does not prevent the system from raising a power alarm. Add an additional power supply for redundancy (n+1) to ensure you have covered the maximum power budget for your specific configuration.

    In our example, a basic configuration (3 power supplies, standard) would require two additional power supplies, one for the minimum power level and second as the redundant power supply. In a redundant AC system (6 power supplies, standard), the system would have sufficient power supplies for both minimum and n+1 redundancy.

  3. Calculate how much power the power supplies need. To determine the power required, multiply the number of power supplies by the power supply wattage and divide by the efficiency of the power supply. The efficiency rate accounts for the loss of energy within the power supply and is 89 percent for PTX10008 power supplies.

    For example, if you have an AC system with four power supplies:

    = 4 (2700 W) / (efficiency rating)

    = (10800 W) / (0.89)

    = 12135 W

JNP10K-PWR-AC Power Specifications

PTX10008 and PTX10016 redundant-configuration routers can use either AC or DC power supplies; base-configuration routers are AC only. You can run the JNP10K-PWR-AC power supply only in JNP10008-SF fabric systems.

Table 6 lists the power specifications for the AC power supply (JNP10K-PWR-AC) used in a PTX10008 or PTX10016 chassis.

PTX10008 Power Cables Specifications

Most sites distribute power through a main conduit that leads to frame-mounted power distribution panels, one of which can be located at the top of the rack that houses the router. An AC power cord connects each power supply to the power distribution panel.

Note

In North America, AC power cords must not exceed 15 feet (approximately 4.5 meters) in length, to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52 and Canadian Electrical Code (CEC) Section 4-010(3). The cords shipped with the router to North America and Canada are in compliance.

PTX10008 AC, high-voltage alternating current (HVAC), and high-voltage direct current (HVDC) power supplies have specific cord requirements. Use the following sections to determine the cable requirements based on the model of your power supply and any mode settings:

JNP10K-PWR-AC Power Cable Specifications

Each JNP10K-PWR-AC power supply has two independent 16 A rated AC inlets on the faceplate.

Each detachable AC power cord is 8 feet (approximately 2.5 meters) long. The coupler end of the appliancecord inserts into the AC appliance inlet on the faceplate of the AC power supply. The coupler type is C19 as described by the International Electrotechnical Commission (IEC) standard 60320. The plug end of the power cord fits into the power source outlet that is standard for your geographical location.
