How to change the default sensor names on G5 PDU’s
Contents
Introduction
When connecting an environmental or other sensor to the G5 PDU it will be automatically detected and will be shown in the WEB interface with a default name , like “T” for Temperature or “RH” for a humidity (Relative Humidity) sensor.Using external tools to monitor these sensors can cause confusion as all the sensors will be shown identical with their default name, making it hard to identify the correct one from a list.
Currently sensor names can’t be changed today via the WEB interface.
Purpose
This document will show a possible way to change the sensor name by using the a free SNMP MIB browser from ManageEngine, while the steps can be easily adopted using your own SNMP MIB browser.Requirements

SNMP write access to the PDU.
Procedure
Enabling SNMP on a G5 PDU
- Login with Admin or Manager account
- Check firmware and upgrade if necessary
- Setup SNMP manager on the PDU
Login with Admin or Manager account
- Connect PDU to power and setup a network connection to the PDU using the IP address shown at the display of the PDU. It will be either one given by your DHCP server or a default IPv4 address, that will be activated if the PDU doesn’t receive an address within about 1-2 minutes from a DHCP server. Open a web browser and enter the IP of the G5 PDU. Login into the PDU via WebGUI using your login credentials or use default login at new delivered PDUs:
- Username: admin manager
- Password: 12345678 12345678
- The system will ask you to setup your own password before you can proceed. Make sure you remember the new password.
- At the start screen click at “Environmental” to check, if all connected sensors were detected.
In the example above only one temperature sensor was connected and correctly detected. If you have multiple sensors connected those will be shown in the order of their response to the internal “broadcast” when getting connected.
Check firmware and upgrade if necessary
To double check the correct firmware of your PDU, please click at the “Home” symbol and at “Identification”. Scroll down to the PDU#1 information and check the current firmware version. While it’s generally recommended to run the PDU at the latest applicable firmware version, you can change the name with every FW version. Please make sure, you have the original firmware zip-file available.
If you don’t have this zip-file available anymore for the firmware your PDU is running, please download the latest version from our Download Center and upgrade the firmware of the G5 PDU following the instructions in the release document. Link to the PDU Download Center:

Setup SNMP manager at the PDU
- To get access via SNMP to the PDU you need to enter and enable an SNMP manager at the PDU. Click at the “Gear” symbol and to “SNMP Manager”
- The SNMP functionality should be enabled by default for SNMP v1, v2c and v3, as well as the SNMP ports are set to the typical default values. Some IT departments change them for security reasons or disable/restrict communication via their firewalls. If you get later no connection to the PDU via your MIB browser, please make sure you have set these port numbers to your individual company SNMP configuration and theirs no firewall restriction in place.
- This will open the setup window on the right side of the screen and allows you to enter your IP address as well as the SNMP community strings. Finally move the slider to the right to enable this SNMP Manager.
- The community strings are the SNMP “passwords”, differentiating between “Read” and “Write” authorization for the SNMP manager accessing the device.
- Most IT departments change them from these shown international agreed default values to improve the security. It’s strongly recommended to do so. For this example configuration we keep them by their default values, but please make sure you change them to your companies’ internal values.
- Note: To change a sensor name via SNMP you’ll need the write community string!
- Leaving the IP address field at the default address “0.0.0.0” will allow any connected IP device to act as an SNMP manager. This might be risky too. Please check with your IT security if that’s OK and configure accordingly.
SNMP V3 usage
You can use encrypted SNMP V3 too. If you do so, please add the SNMP manager accordingly at the bottom of the SNMP manager screen – see below. However, this instruction will follow the steps using SNMP V1/V2c only.
Note: Please keep the WEB interface of the PDU open in the background to validate your changes. Due to a timeout, it might be necessary to re-login later.
Changing sensor names via a MIB browser
- Install MIB browser
- Load the Panduit MIB (Management Information Base)
- Check connected sensors and their current names
- Change sensor name
Install the MIB browser
- Please install the MIB browser, make sure it has all necessary access rights and open the program
- Identify the folder position of your unpacked G5 PDU firmware zip-file. This file includes the private MIB file, you need to identify the correct sensor and rename it.
Note: If you start the MibBrowser tool it might open with an error message of being unable to load MibModules. Just click OK and ignore it.
Load the Panduit MIB (Management Information Base)
- At the top menu bar click at the most left icon “Load Mib Modules”
- Select at the G5 PDU firmware folder the “Panduit.MIB” file and click “Open”.
- You can now open the MIB tree by just clicking at the “+” symbols. The sensors are located under “pdug5Environment” – see below.
Check connected sensors and their current names
Note: In this example only one temperature sensor is connected to the PDU. If there are multiple and different sensors are connected follow the next steps for each sensor type and name. You’ll find the other sensor types in the MIB tree sorted by their function.
- To get a list of all connected temperature sensors open the MIB tree more till you see the path “pdug5TemperatureName”. Select it clicking at it.
- At the “Host” field enter the IP address of the PDU and check the correct port number for SNMP communication.
- Enter your correct SNMP community strings in the two field below. “Community” refers to the ‘read’ authorization, “Write Community” refers to the ‘write’ level. You’ll need to enter both correctly to be able to change the sensor names.
- By clicking at the “SNMP Walk” icon you’ll get an overview of the temperature sensors and their current names.
The list above shows all possible sensors and just one connected and named “T” as previously seen in the WEB interface if the PDU too.
Change sensor name
- Identify the correct number of the sensor in the above list and add it’s number (ONLY the number1) at the field “Object ID” behind the already shown string.
- For this example: shown in the OID field is: .iso.org.dod.internet.private.enterprises.panduit.g5.pdug5.pdug5Environment.pdug5TemperatureTable.pdug5TemperatureEntry.pdug5TemperatureName
- To change the name of sensor “pdug5TemperatureName.1.1” you need to add “.1.1” behind the string to finally shown as: .iso.org.dod.internet.private.enterprises.panduit.g5.pdug5.pdug5Environment.pdug5TemperatureTable.pdug5TemperatureEntry.pdug5TemperatureName.1.1
- At the “Set Value” field you enter the proposed new name for this sensor.
- For this example we call it “TempSensor-1”.
- Note: You can use almost any description with a maximum length of 31 characters. Just keep in mind, that longer descriptions might cause worse visibility in overviews and dashboards later. It’s recommended to select a unique but still short description for the sensor
- To change the sensor name now click at the menu bar to the “SET SNMP” Icon
- This will send the SET request and change the name of the sensor immediately – see below:
- The sensor will now appear everywhere with it’s new name, allowing easier identification.
