Step 1. PDU power off ?
Check the PDU is power ON or not.

Check and make sure PDU level is unique and not duplicated in the same PDU group.
(Please refer to P.1 for the PDU level setting)
2. GUI shows from a certain level PDU to the last one disconnected
Step 1. Cable disconnected, loose or defective ?
Check the Cat. 5/6 cable connection to PDUs and network devices. Make sure the
connectors are fi rmly attached. And check if any defects on your cable or not. If yes,
replace a new one.
Step 2. The fi rst disconnected PDU failed ?
Unplug the Cat. 5/6 cable on the fi rst disconnected PDU, then plug it to the second
disconnected PDU to check if the problem caused by the fi rst disconnected PDU.
3. GUI shows the whole group of PDU(s) disconnected
Step 1. Cable disconnected, loose or defective ?
Check the Cat. 5/6 cable connection to PDUs and network devices. Make sure the
connectors are fi rmly attached. And check if any defects on your cable or not. If yes,
replace a new one.
Step 2. IP dongle failed ?
i. Check if the network setting of the IP dongle is correct or not. If duplicated IP address
is in a network, it may cause such problem.
ii. Disconnect the IP dongle from the network and try to direct connect the Cat. 5/6 cable
from IP dongle < LAN > port to a computer network port and use IP Setup utilities
to check if the IP dongle can be found or not. If it cannot be found, the IP dongle may
be failed.
Step 3. 1st level PDU failed ?
Move the IP dongle from 1st level PDU to 2nd level PDU to check if the problem
caused by 1st level PDU’s failure or not. If yes, replace 1st level PDU.
