PDU Network Daisy Chain
What will happen if an Ethernet cable is disconnected in the PDU daisy-chain?
For example, if four PDUs are connected and the cable connecting Guest 1 and 2 is disconnected,
then Guest 2 and 3 will no longer be detected by the Host PDU.
An event showing that Guest 2 and 3 are removed will be recorded in the Host PDU. Meanwhile,
Guest 2 and 3 will create a new daisy-chain where Guest 2 becomes a Host and Guest 3 becomes
Guest 1 to the new Host.
In the above example, if the disconnected Ethernet cable is re-connected, will the role of the PDUs
stay the same?
Yes, when the disconnected cable between Guest 1 and 2 is re-connected, Guest 2 and 3 will revert to
their previous roles.
What happens if one PDU in the daisy-chain is powered off?
For example, if four PDUs are connected and Guest 1 is powered off, an event
showing that Guest 1, 2 and 3 are removed will be recorded in the Host PDU. Guest 2 and 3 will not
create another daisy-chain.
Does the Host PDU record the logs of the Guest PDUs and itself?
Yes, the Host PDU records the logs from all Guest PDUs daisy-chained to it.
Will the Logs of the Guest PDUs recorded in the Host PDU be cleared if the Guest PDUs are removed
from the Host PDU?
No, the Logs of the Guest PDUs will remain even after the Guest PDUs are removed.
Does the Host PDU record the Status Records of the Guest PDUs and itself?
Yes, the Host PDU records the Status Records for all the PDUs in the daisy-chain.
