4 Avocent PM PDU Installer/User Guide
Daisy chained configuration
In a daisy chained configuration, multiple PM PDUs are connected to one another and managed by
a single main PM PDU. The PM PDUs are linked together with CAT 5 cables connected through
the PM PDU’s IN and OUT ports. Avocent PM PDUs can be daisy chained with Cyclades
®
PDUs.
NOTE: You cannot daisy chain an Avocent PM PDU from a Cyclades PDU.
You may manage a maximum of five PDUs or a maximum of 128 outlets by connecting multiple
PM PDUs to the main PM PDU. The following example shows two PM PDUs operating in a daisy
chained environment.

he main PM PDU, which is connected
to a workstation or management appliance.
2. Connect the other end of the CAT 5 cable to the IN port of the secondary PM PDU.
Repeat these steps until you have connected the desired number of PM PDUs.
