
One device is connected to another device via two cascading cables -
USB and Ethernet cables.
Power-Sharing Restrictions and Connection (for iX7™ Only)
Two iX7
™
PDUs can share power supply to their controllers via
EXPANSION ports, so that when either iX7
™
controller fails to receive DC
12V power from its inlet, it continues to receive backup power from
another iX7
™
PDU which functions properly and therefore remains to be
accessible to users.
For documentation purpose, the term "power-sharing mode" is used
to describe the status when the 12V power supply from the inlet to
an iX7
™
controller fails and that iX7
™
controller is receiving power
from another iX7
™
PDU.
Before making a power-sharing connection, first read Power-Sharing
Configurations and Restrictions (on page 50), and remove unsupported
equipment from BOTH iX7
™
PDUs.
When a PDU enters the power-sharing mode, some data/operations
remain to be available while other data/operations are no longer
available.
Unavailable data or operations on the PDU that enters the
power-sharing mode:

All outlets lose power, and enter the "disabled" state.

No outlet switching can be performed if the iX7
™
is an
outlet-switching capable PDU.
