Chapter 5: PDU Linking on the PRO3X

Overview
The PDU Linking feature allows the linking configuration of a single
master PDU unit to multiple link units for faster and more efficient power
management, as only one IP address is required to communicate with up
to 8 linked units. Only one master unit is connected to the network in
PDU Linking, which allows a cost-efficient PDU operation and networking
infrastructure.
The master PDU is the first PDU in the chain. The user configures the PDU
as the master during setup with up to seven link units connected in
sequence in the chain. The master PDU has full knowledge of the location
of the connected link units in the chain, as well as the power and
environmental information of all link
When you create a master and link configuration in a chain, you log in to
the master unit with visibility to control both the master unit and the
connected link units from within the GUI, SNMP, and CLI.
The administrator privilege is required for all management actions
(adding, configuring, releasing) of the PDU Linking feature. Each PDU in
the chain can be monitored and managed from anywhere by the network
protocols HTTP(S), SNMP, SSH, Telnet, and Modbus.
All units in the linked chain should be the same model PDU. All units
must run the same firmware version, which can be upgraded respectively
for each unit in the chain.
The first link unit can provide backup power to the master's network card
to maintain connectivity in the event the master unit loses input power.
This arrangement requires two cables between the master PDU and the
first link unit. (See linking illustration on right.)
