T1600 AC 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 11,765 W per each three-phase delta AC power supply or 11,775 W per each three-phase wye AC power supply.

If you do not plan to provision 11,765 W per each three-phase delta AC power supply or 11,775 W per each three-phase wye AC power supply, you can use the information in Table 1, Table 2, 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 an AC-powered router.

Table 2 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 Interface Module Reference.
