Power Considerations; Estimating Power Requirements - Cisco ASR 5000 Series Installation Manual

▀ Power Considerations

Power Considerations
Each chassis supports one or two 165-amp PFUs.
The following table describes the power requirements for the chassis.
Table 46. Chassis Power Requirements
Characteristic
Input Voltage
TUV Rated Peak Current Load
Maximum Peak Power Load
Empty Chassis Maximum Power Load (includes fan trays)
Line Card (rear-installed) Maximum Power Load
Application Card (front-installed) Maximum Power Load

Estimating Power Requirements

Use the following formula to estimate the total power consumption for each deployed chassis:
(Total Application Card Maximum Power Load) + (Total Line Card Maximum Power Load) + (Chassis Maximum
Power Load)
The calculation for estimating the power required for an ASR 5000 installation with 3 PSCs, 2 SMCs, 2 SPIOs, 2 RCCs,
and 4 Ethernet 1000 line cards is as follows:
(250W x 3) + (130W x 2) + ((20W x 2) + (13.5W x 4)) + 800W = 1934W
