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 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 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 PIC Guide .
Table 1: Base AC Power Requirements
Component | Power Requirement (Watts) |

Base system, not including FPCs and PICs (includes five T1600-SIBs, one host subsystem [T-CB and 600, 1600, or 2000 Routing Engine], one SCG, cooling system at normal speed, and craft interface), and two power supplies | 1774 W |

- Example of calculating typical power consumption for maximum
configuration:Base System + 8 T1600-Type 4 FPCs + 1 LCC-CB + 1 RE-C1800 + 1 SCG + 16 PICs + 5 (TXP-T1600 SIBs – T1600 SIBs) + fan tray (full speed – normal speed) =1774 W + 8 (638 W) + 56 W + 96 W + 11 W + 16 (186 W) + 5(232 W —203 W) + 864 W =1774 W + 5104 W + 56 W + 96 W +11 W + 2976 W + 145 W + 864 W + 91 W= 11,026 W
- Example of calculating system thermal output:Watts DC/0.293 = BTU/hr11,117/0.293 = 37.631 BTU/hr
