Power-Sharing Restrictions and Connection

Two devices can share power supply to their controllers via a designated port, so that when either
controller fails to receive adequate power from its inlet(s), it continues to receive backup power from
another device which functions properly and therefore remains accessible to users.
For documentation purposes, the term "power-sharing mode" is used to describe
the status when the PDU controller is receiving power from another device.
Before making a power-sharing connection, first read Power-Sharing Configurations and Restrictions,
and remove unsupported equipment from BOTH PDUs.
After a PDU enters power-sharing mode, some data/operations are no longer available.
▶
Unavailable data or operations in power-sharing mode:
• • All outlets lose power, and enter the "disabled" state.
• •
No outlet switching can be performed.
• •
All internal sensors become "unavailable", including sensors of inlets, outlets, and OCPs.
Exception: Only energy data remains available.
• •
Communications with relay/meter boards are lost. Therefore, firmware upgrade may fail.
▶
Available data or operations in power-sharing mode:
• •
Change software settings, such as customizing names, modifying network settings, configuring
thresholds, and so on.
• • Monitor the status of connected environmental sensor packages, or configure/control their settings.
• •
Operate the front panel display.
▶
Events that occur when entering power-sharing mode:
• •
The power supply sensor enters the fault state.
