T4000 DC Power Requirements on page 97
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 56 A @
–48 VDC per input for the 60-A DC power cables connected to each power supply.
Table 65 on page 97 lists the power requirements for various hardware components
when the router is operating under typical voltage conditions.
You can use the information in
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.
