Timeout Settings  
The Timeout Setting (Shown in Figure 10). [Edit=>Timeout Settings]  
is used to specify the wait time when scanning for network PDU  
devices. When there are many devices on the local network, it may  
take extended periods of time to locate all the devices. The timeout  
function is used to limit the search time.  
The default setting is 3 seconds. Valid values are 3 to 60 seconds.

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.  
Ethernet  
Host  
Guest #1  
Guest #2  
Guest #3  
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 (v1.08 or above).  
How to connect the PDUs together?  
Use one Ethernet cable and connect one end of it to the daisy-  
chain (Out) port on the Host PDU and the other end to the daisy-  
chain (In/ENV) port on the Guest 1 PDU to connect the PDUs (as  
shown below).  
Host PDU  
Out port  
Guest #1 PDU  
In/ENV port  
What remote management protocols are supported in PDU daisy-  
chains?  
Currently users can monitor and control daisy-chained PDUs  
through Web interface (HTTP/HTTPS) or SNMP protocols.  
What functions on the Web pages does daisy-chain support?

Appendix C-PDU Daisy-Chain Function  
How to switch between Host and Guest PDUs on the Web  
interface?  
Functionality supported by daisy-chained PDUs will have the Host/  
Guest # drop down menu displayed on the Web interface (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.  
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.  
Ethernet  
Host  
Guest #1  
Guest #2  
Host  
Guest #3  
Guest #1  
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  
o, 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.

Appendix C-PDU Daisy-Chain Function  
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.  
Will the Status Records of the Guest PDUs logged in the Host  
PDU be cleared if the Guest PDUs are disconnected from the Host  
PDU?  
Yes, once the Guest PDUs are removed, the Status Records logged  
in the Host PDU will be cleared. As long as the Host PDU does not  
connect to other PDUs, the Status Records of the disconnected  
PDU can be displayed when it is re-connected to the Host PDU. If  
the Host PDU connects to dierent PDUs, the Status Records of the  
removed PDU will be entirely cleared.  
Are the Guest PDUs able to connect to the network when they are  
daisy-chained?  
Yes, even when the PDUs are daisy-chained, the Guest PDUs are  
able to connect to the network directly. Note that a Guest PDU will  
require having its own Ethernet cable connected to the network.  
What will happen if a 5th PDU is added to a daisy-chain?  
The maximum number of PDUs that can be connected in one daisy-  
chain is 4. The daisy-chain functionality will not work until the fifth  
PDU is removed.  
What is the maximum recommended length of the Ethernet cable  
to daisy-chain the PDUs?  
50 ft (15 m)
