MX10008 Power Planning

 

MX10008 power specifications and requirements are described in the following topics. Use the information to calculate the power consumption for the MX10008 and plan your configuration’s power requirements.

Power Requirements for an MX10008 Router

Use the information in this topic to calculate power requirements of your MX10008 configuration and the number of power supplies required for different MX10008 router configurations.

Note

The calculations in this topic represent the maximum power requirements that you need to budget for your MX10008 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 MX10008 Configuration

  2. Calculating the Number of Power Supplies Required for Your MX10008 Configuration

Calculating the Power Consumption of Your MX10008 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 1 if your router is configured as either the standard base or redundant configuration.

    Table 1: Chassis Power Consumption for Standard Configurations

    Base Configuration

    Redundant Configuration

    350 W/330 W

    Switch fabric board (SFB)

    1000 W

    1200 W

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

    Table 2: Line Card Power Consumption

    Number of Line Cards

    MX10K-LC2101 (240 Gigabit Ethernet mode @104° F (40° C))

    7

    8225 W

    9975 W

    8

    9400 W

    11400 W

    For example, for an MX10008 with eight MX10K-LC2101 line cards, the maximum power consumption @400 Gigabit Ethernet mode is:

    = 8* 1425 W= 11400 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 eight cards to a redundant configuration.

    (11400 W) + (2650 W)

    = 14050 W required

Calculating the Number of Power Supplies Required for Your MX10008 Configuration

Use this procedure to calculate the number of power supplies required by your router configuration. The minimum power configuration for MX10008 routers is three 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 3 shows the power available for installed power supplies.

    Table 3: Total Power Available

    Power Supply Module Models

    With Three Power Supplies

    12,500 W

    JNP10K-PWR-DC2 dual feed, high power (80-A) setting

    27,500 W

    JNP10K-PWR-DC2 dual feed, low power (60-A) setting

    22,000 W

    JNP10K-PWR-DC2 single feed, high power (80-A) setting

    13,750 W

    JNP10K-PWR-DC2 single feed, low power (60-A) setting

    11,000 W

    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 Setting the JNP10K-PWR-AC2 DIP Switches 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 an MX10008 AC system would require 11800 W with eight line cards. In this example, we calculate the total power available for this configuration:

    = (14050 W) / (2700 W)

    = 5.20

    Round up the result to 6 AC power supplies.

  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 MX10008 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

    Table 4 shows how much power is required for various configurations.

    Table 4: Total Power Required

    15169 W

    14045 W

    6

    18204 W

    16854 W

Note

We recommend that you maintain six 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.

MX10000 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.

MX10008 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:

MX10008 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 an MX10008 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 intra-building 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 an MX10000 to Earth Ground. 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 an MX10008 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.
