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 soware adjusts the system
capacity and reallocates power to the FRUs based on the new system capacity. Table 20 on page 42
shows system behavior in dierent scenarios with 60 A DC power supply modules.
Table 20: System Behavior in Dierent Scenarios with 60-A DC power supply modules
Input voltage: < 40 V Input voltage: 40 V to 72 V
60 A DC mode The power supply module is powered o and
won’t turn on when the system is powering
up.
Normal operaon.
PTX10001-36MR with two
power supply modules
The power supply modules are oine and the
system is powered down.
Normal operaon.
PTX10001-36MR with one
power supply modules
The power supply modules are oine and the
system is powered down.
Normal operaon, but there’s
no power supply module
redundancy.
In all these scenarios, power management acons can be dierent but determinisc 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 specicaons required by the local code, laws, and
standards. The insulaon 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.
