Power Requirements for an MX240 Router

The following tables list the MX240 component power requirements. Table 1 lists the MX240 base system power requirement. Table 2 lists the FRU power requirements for Switch Control Boards (SCBs), Routing Engines, Modular Port Concentrators (MPCs), Modular Interface Cards (MICs), and Dense Port Concentrators (DPCs).

Calculating Power Requirements for MX240 Routers

The information in this topic helps you determine which power supplies are suitable for various configurations, as well as which power supplies are not suitable because output power is exceeded. You determine suitability by subtracting the total power draw from the maximum output of the power supplies. Afterward, the required input power is calculated. Finally, you calculate the thermal output. A sample configuration is provided in Table 3.

We recommend that you provision power according to the maximum input current listed in the power supply electrical specifications (see AC Power Supply Electrical Specifications for the MX240 Router and DC Power Supply Electrical Specifications for the MX240 Router).

Use the following procedures to calculate the power requirement:

  1. Calculate the power requirement.
  2. Evaluate the power budget.
  3. Calculate input power.
  4. Calculate thermal output (BTUs) for cooling requirements.

The following sample configuration shows an MX240 router with:

  • Two 16-port 10-Gigabit Ethernet MPCs with SFP+

  • Two SCBs with two (redundant) RE-1800x2 routing engines

  • High-capacity cooling system

    Note

    The high-capacity cooling system satisfies cooling requirements of MPCs, and must be used for proper cooling.

  1. Calculate the power requirements (usage) using the values in Power Requirements for an MX240 Router as shown in Table 3.

    Total output power

    Output power excluding cooling system

    1470 W

  2. Evaluate the power budget. In this step, we check the total output power against the maximum output power of available power supply options.Note

    The power for the cooling system comes from a different tap on the power supply, reserved for the cooling system only. The cooling system power requirement does not need to be deducted from the output power budget of the power supply.



    Table 4 lists the power supplies, their maximum output power, and unused power (or a power deficit). See DC Power Supply Electrical Specifications for the MX240 Router and AC Power Supply Electrical Specifications for the MX240 Router for more information about the MX240 power supply electrical specifications.

    2600 W

    1200 W

    1 For this configuration, output power excluding the cooling system is 1400 W.

  3. Calculate input power. In this step, the input power requirements for the example configuration are calculated. To do this, divide the total output requirement by the efficiency of the power supply as shown in Table 5.

    1 These values are at full load and nominal voltage.

    2 For this configuration, total power is 1485 W.

  4. Calculate thermal output (BTUs). To calculate this, multiply the input power requirement (in watts) by 3.41. See Table 6.

    Table 6: Calculating Thermal Output

    Power Supply

    Thermal Output (BTUs per hour)

    1669 * 3.41 = 5576 BTU/hr

    MX240 DC Normal-capacity

    1515 * 3.41 = 5166 BTU/hr

    MX240 DC High-capacity

    1515 * 3.41 = 5166 BTU/hr
