T1600 DC Power Requirements

 

To allow for future growth so that you can operate the router in any hardware configuration without upgrading the power infrastructure, we recommend that you provision the following for each power supply.

Note

Although the power requirements for each input varies, we recommend that you provision the same amount of power for each input, or DC power cable when using terminal jumpers.

  • Three-input 240-A DC power supply: 67 A @ –48 VDC per input

  • Four-input 240-A power supply: 50 A @ –48 VDC per input

  • Six-input power supply: 56 A @ –48 VDC per input

Table 1 lists the power requirements for various hardware components. For PIC power requirements, see the T1600 Core Router Interface Module Reference.

You can use the information in Table 1 and the T1600 Core Router Interface Module Reference to calculate power consumption for various hardware configurations, input current from a different source voltage, and thermal output, as shown in the following examples for a DC-powered router.
