Appendix C - Pdu Daisy-Chain Function - CyberPower Outlet Series User Manual

APPENDIX C - PDU DAISY-CHAIN FUNCTION

The daisy-chain function allows up to four PDUs to be
connected together to be monitored and controlled from
one IP address.
When PDUs are connected, two roles are defined: Host
and Guest. Up to three Guest PDUs can be connected to
one Host PDU. The Guest PDUs will be recognized by serial
number and their order within the daisy-chain.
Note: To perform the daisy-chain function, the firmware
version of the connected PDUs needs to be the same (v1.07
or above).
How to connect the PDUs together?
Use one Ethernet cable and connect one end of it to the
daisychain (Out) port on the Host PDU and the other end
to the daisychain (In/ENV) port on the Guest 1 PDU to
connect the PDUs (as shown below).

Can I upgrade the firmware version of the Guest PDUs
through the Host PDU?
Yes, you can upgrade the firmware using the Upgrade and
Configuration Utility, FTP (network connection required),
or USB port. Once the Hostcompletes the PDU firmware
upgrade, it will trigger its Guest PDUs to upgrade the
firmware automatically. It takes about 5 minutes for the
Guest PDUs to upgrade, regardless of the number of PDUs
in the series.
