Calculating Power Requirements for a PTX10016 Router

Use the information in this topic to calculate power requirements of your PTX10016 configuration and the number of power supplies required for different PTX10016 router configurations.

Caution

To ensure adequate power and to avoid raising a power alarm, we recommend that you maintain N +1 power supplies in your router 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 PTX10016 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. Calculating the Power Consumption of Your PTX10016 Configuration

  2. How to Calculate the Number of Power Supplies Required for Your PTX10016 Configuration

Calculating the Power Consumption of Your PTX10016 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.

Caution

To ensure adequate power and to avoid raising a power alarm, we recommend that you maintain n +1 power supplies in your router 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 PTX10016 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.

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 either for the standard base, or redundant configuration.

    Table 2: Chassis Power Consumption for Standard Configurations

    Note

    *In a redundant DC configuration, a maximum of 14 PTX10K-LC1101 or 13 PTX10K-LC1105 line cards are supported.

    Note

    The PTX10K-LC1104 line card is designed to comply with NEBS regulations on the PTX10016 Packet Transport Router when these routers are used in typical configurations. In a typical configuration, a PTX10016 router supports up to 16 line cards, with up to four PTX10K-LC1104 line cards in any of the 16 slots.

    Note

    To comply with EMC regulations, you must also install front panel on the PTX10016 chassis. See Installing the Front Panel on a PTX10000.

    For example, for a PTX10016 with six PTX10K-LC1102 and five PTX10K-LC1101 line cards, the maximum power consumption is:

    = 6 (power consumed by PTX10K-LC1102 in watts) + 5 (power consumed by PTX10K-LC1101 line cards in watts)

    = 6 (650 W) + 5 (1150 W)

    = (4050 W + 5750 W)

    = 9800 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 line cards and three PTX10K-LC1101 cards to a redundant configuration.

    (9800 W) + (5900 W)

    = 15700 W required

How to Calculate the Number of Power Supplies Required for Your PTX10016 Configuration

Use this procedure to calculate the number of power supplies required by your router configuration. The minimum power configuration for PTX10016 routers is three power supplies. However, using the calculated minimum power configuration does not prevent the system from raising a power alarm. To ensure you do not log power alarms, you must configure your router for n+1 power supplies.

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

  1. Determine the power available from the power supplies. Table 5 shows the power available for installed power supplies.

    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 if other power supplies are set at 30 A. This design is to prevent overloading of the power supply that is set to 20 A. See Power Input and Output Voltages for JNP10K-PWR-AC2 Power Supplies for details on setting the dip switches.

  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, then rounding up.

    In the previous examples, we calculated that a PTX10016 AC system would require 15700 W with five PTX10K-LC1102 and three PTX10K-LC1101 line cards. In this example, we calculate the total power available for this configuration:

    = (15700 W) / (2700 W)

    = 5.81

    Round up the result to 6 AC power supplies. A base configuration would require an additional power supply; a redundant AC system would have sufficient power supplies.

JNP10K-PWR-AC Power Specifications

PTX10008 and PTX10016 redundant configuration router can use either AC or DC power supplies; base configuration routers are AC only.

PTX10000 Power Cables Specifications

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

Each detachable AC power cord is 8 feet (approximately 2.5 meters) long. The appliance coupler at the female end of the cord 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 at the male end of the power cord fits into the power source outlet that is standard for your geographical location.

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.

PTX10000 AC, high voltage alternating current (HVAC), and high voltage direct current (HVDC) 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:

PTX10000 Grounding Cable and Lug Specifications

For installations that require a separate grounding conductor to the chassis, the router must be adequately grounded before power is connected to ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements. To ground a PTX10000 chassis, connect a grounding cable to earth ground and then attach it to the chassis grounding point on the rear of the chassis beneath.

Warning

The router is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth ground for installations that require a separate grounding conductor to the chassis.

Warning

To comply with GR-1089 requirements, all intrabuilding copper cabling used for SFP+, QSFP+, and QSFP28 ports must be shielded and grounded at both ends.

Caution

Before router installation begins, a licensed electrician must attach a cable lug to the grounding cables that you supply. See Connecting Earth Ground to a PTX10000. A cable with an incorrectly attached lug can damage the router.

Before connecting the router to earth ground, review the following information:

  • Two threaded inserts (PEM nuts) are provided on the lower rear of the chassis for connecting the router to earth ground. The grounding points are spaced at 0.63  in. (16 mm) centers.

  • The grounding lug required is a Panduit LCD6-10A-L or equivalent (provided). The grounding lug accommodates 6 AWG (13.3 mm²) stranded wire. If one or more JNP10K-PWR-DC2 power supplies are installed in the chassis and set for high input (80-A), use the Panduit LCD4-14A-L or equivalent (provided). This lug accommodates 4 AWG (21.1mm²) stranded wire.

  • The grounding cable that you provide for a PTX10000 must be the same size or heavier than the input wire of each power supply. Minimum recommendations are 6 AWG (13.3 mm²) stranded copper wire, Class B; 90° C wire, or as permitted by local code.
