Upgrading to the High Capacity AC Power System
Before you upgrade a PTX5000 to the High Capacity AC power system from a normal-capacity power
system:
• Ensure that the No Redundant Power for System alarm is not displayed when you run the show chassis alarms
operational-mode CLI command.
If the No Redundant Power for System alarm is displayed, see
System Power Zones" on page 182
zones for normal-capacity PSMs. Modify your hardware configuration so that the PTX5000 power
system is redundant. Once redundant power is configured and the alarm is no longer displayed, you
can begin the upgrade procedure.
• Ensure that the PTX5000 is running Junos OS release 14.1R2 or a later 14.1 release, or Junos OS
release 14.2 or later.
NOTE: If you are upgrading from normal-capacity Delta or Wye AC PDUs, you must begin this
procedure with the left PDU when viewed from the rear of the chassis (labeled PDU1 on the
chassis).
