Power Cable Requirements
Sizing Power Cables
The following guidelines should be adhered to when sizing cable gauges for connecting the PFUs to a
rack-mounted power distribution panel.
•
Each conductor between the PDF and PDP should be calculated assuming a 0.3 volt drop from the PDF
to the panel.
•
Each cable between the PDP and ASR 5500 PFUs should be calculated a 0.3 volt drop from the panel
to the chassis. This is a total voltage drop of 0.6 volts.
•
Use high-flex, multiple-strand cable (minimum 4 AWG) between the power distribution panel and the
chassis.
