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 67 A @
–48 VDC per input on each three-input 240-A power supply or 50 A @ –48 VDC per
input on each four-input 240-A power supply. Although the power requirements for each
input varies, we recommend that you provision the same amount of power for each input.
Table 47 on page 352 lists the power requirements for various hardware components
when the router is operating under typical voltage conditions. For PIC power requirements,
see the T1600 Core Router PIC Guide.
You can use the information in Table 47 on page 352 and the T1600 Core Router PIC Guide
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.
