NOTE: Up to 40 rPDUs can be connected in a daisy chain, and the total cable length should be within 40 meters (131.23 ft).
7.2 Daisy Chain Web Page Initial Setup

Step 1
Enter the Daisy Chain page under Network, and check whether the total number of ONLINE units matches the actual number of the connected rPDUs.

Step 2

Follow the ID sequence of rPDUs connected in series according to Chapter 7.1

Connection of rPDUs in A Daisy Chain and click the

button to set up

each rPDU’s address in the address field. You can refer to the MAC on the RMC or click

Go to the User page under Configuration shown in the figure below, and click the save button to save this rPDU’s address to USER Default. For the rest of chained rPDUs, log in to each Web Page and perform the procedures mentioned in Step 3.

75

NOTE:
1. The default address of each chained rPDU is 1. When an rPDU is connected online and finds that the set address has already been occupied, it will automatically find the next vacant address to go online. For the first time connection, the address sequence will be based on the online time of each rPDU and may be different from the ID sequence defined in the hardware configuration mentioned in Chapter 7.1 Connection of rPDUs in A Daisy Chain.
2. Please confirm that all addresses are entered before clicking the save button in order to ensure that all chained rPDUs receive the new addresses at the same time.
3. After the daisy chain web page initial setup is completely done, the rPDUs will save users’ setting values individually. When the rPDUs are reconnected online, they will give priority to reconnecting with the set addresses.

After updating the firmware of the rPDU, users can click the button to send this rPDU’s RMC, IPM or DPB firmware to all chained rPDUs for firmware upgrade, or click the button to send this rPDU’s RMC, IPM or DPB firmware to a specific rPDU for firmware upgrade.

When the firmware is being sent to other rPDU(s), the Action icon of the original rPDU

will change to

. When the icon appears, it means that the firmware is being

uploaded. Users can click the icon to terminate sending the firmware.

As for the rPDU(s) receiving the firmware, the Action icon will change to . After the firmware is received or upload is terminated, it will return to the original state.

After the firmware is received, users can go to the Event Log page under History to check how many rPDUs successfully receive the firmware and go to the Inventory page under System to check whether the firmware version is successfully updated.
77

NOTE:
1. During the process of uploading the firmware to other rPDU(s), if the web page is idle for a long time to cause logout, it will not affect the firmware upload process. Please ensure that the LAN is still connected.
2. The firmware upload process does not affect the operation of all chained rPDUs; users can switch pages to operate each rPDU normally.

Chapter 8 : Troubleshooting

Problem

Solution

The reset address cannot be saved.

1. Check if the address is set as 1 ~ 40. 2. Check if the same address is set.

The new set address is invalid.

Please make sure whether the new set address has already been occupied by other rPDU. If yes, please reset the rPDU that occupies the address to another vacant address and reset the rPDU that you originally want to set.

The chained rPDUs suddenly change their addresses.

Please reset the address according to 7.2 Daisy Chain Web Page Initial Setup.

The rPDU cannot connect online.

1. Please check whether the first chained rPDU and the last one are connected with the terminal resistors.
2. Please replace the RJ11-RJ11 cable with a new one and check if the total cable length exceeds 40 meters (131.23 ft).
If the above-mentioned solution doesn’t work, please contact Delta customer service.

The Inventory page under System still shows the old version of the firmware after firmware upgrade.

The firmware upload progress bar only indicates the progress of sending the firmware to other rPDU(s). Only after the rPDU(s) completely receive(s) the firmware can the firmware be upgraded.
Please wait for a few minutes and go to the Inventory page under System to confirm.

Unable to send the IPM firmware.

Please make sure that all chained rPDUs have the same input type (e.g. 1p-LN, 3p-WYE, 1p-LL or 3p-DELTA). Different input types of rPDUs will cause failure of sending the IPM firmware.

Firmware upgrade is failed.

If there are continuous failures of sending firmware to other rPDU(s), please unplug the RMC that failed to receive the firmware, re-plug the RMC, wait for the rPDU to go online and try to send the firmware again. If the firmware still cannot be upgraded, please contact Delta customer service.
