60-A Input Feed Power Management
The 60-A DC power supply module capacity changes when the input voltage is below or above the
under voltage limit as follows:
• When the 60-A DC power supply module input voltage is above the input under voltage warning
limit, its capacity is 2700 W.
• When the input voltage is below the input under voltage warning limit, the power supply module
capacity is reduced to 2200 W.
When the input voltage is above the input under voltage warning limit, the software adjusts the system
capacity and reallocates power to the FRUs based on the new system capacity.
shows system behavior in different scenarios with 60 A DC power supply modules.
Table 20: System Behavior in Different Scenarios with 60-A DC power supply modules
60 A DC mode
PTX10001-36MR with two
power supply modules
PTX10001-36MR with one
power supply modules
In all these scenarios, power management actions can be different but deterministic based on the total
system capacity and total system power required. Use the show chassis power detail command to
determine the behavior.
PTX10001-36MR DC Power Cables
You must supply the DC power cables that meet the specifications required by the local code, laws, and
standards. The insulation for the wires in the cables is color coded. Green is ground, black is line, and
white is neutral. The wires are labeled (+) and (–) to indicate their polarity.
Input voltage: < 40 V
The power supply module is powered off and
won't turn on when the system is powering
up.
The power supply modules are offline and the
system is powered down.
