Multiple Chassis Power Sync
Power Sync allows multiple chassis configurations to be powered on and off like
a single chassis. A single power button push on any chassis turns on or off all
chassis in the right sequence. For example, with an embedded host controller,
Power Sync ensures that all downstream chassis are powered up before the
embedded controller is turned on. On power down, it ensures that the embedded
controller is turned off before all downstream chassis are turned off.
With an external host, Power Sync allows all chassis to be powered on or off by
the external host automatically. When an external host is powered on, it prevents
power button pushes on any chassis from turning off any chassis to avoid system
software crashes
Synchronized chassis power coordination requires additional cabling. Two RJ45
connectors on the chassis rear panel provide this coordination. Multiple PXI
chassis may be connected together for power sync purposes. All of the chassis
listed in Table 5, “Keysight PXIe Chassis Supporting Power Sync Capabilities,” on
page 106 have Power Sync connectors on their rear panels.
