Published by Lee Kelly on 18 March 2020

In this guide, you will learn how you can configure your SNMP card for your UPS you will know how to do the following:

  • Logging onto the web interface
  • UPS IP configuration
  • VMware ESXi

Remote monitoring of your UPS Solution provides you with real-time management benefits of the UPS including email alerts, remote configuration, shutdown settings and monitoring of events including temperature and humidity through additional sensors.

Logging onto the web interface

Firstly you will need to go to the web browser and type in your NetMan 204 IP address this is by default By typing this into your browser address bar this should show you the following page.

If you see this page the default login details are “admin” for both the password and username. These can be changed once you have entered the system.

If your login was successful you will be greeted with the following dashboard.

A quick rundown of the dashboard the top is the navigation bar and shows details like device model, system status, any alarms and the user you have logged in as.

Dropping down a little, you can see dashboard, data, system overview and history. These are tabs that allow you to view more detailed information about your UPS system and issues or if the UPS has logged any power off or unexpected power outages.

Now we get to the main screen that shows a visual representation of your UPS system; you can see the blue line as the current power direction. If there is a power outage, you won’t see a line connecting from the pylon to the UPS (in the middle) The battery below the UPS shows the current levels and the block above the UPS is the bypass symbol if the blue line is running through this that means your system is in bypass. You are not getting any protection from the UPS. Finally, the right block of the diagram is the load on the UPS that you are using this specific example is from a three-phase system that is why there are three loads.

Around the edge of the diagram, you can see some more information and general details of the system such as environmental sensors (if you have any attached) and the estimated autonomy as well as the amps and load per phase.

IP Configuration - Via Web Interface

If you navigate to the UPS configuration menu you should see all the settings that are configurable if you navigate to the network heading and then click on the configuration tab you will see the following.

This menu allows you to change all the setting of the IP address so that you can configure your NetMan 204 to your network. Firstly you will see boxes greyed out you are able to set these manually if you switch the network protocol from DHCP to static IP.

This allows you to add an IP address, Network Masks Gateways and DNS you can configure these how you would like and once you have finished you can click save at the bottom of the page. You may receive a popup saying your NetMan has to restart for settings to take place click yes. Once your NetMan has restarted then you can connect to it with your new settings.

Configuring VMware ESXi Shutdown

First, you need to go to the settings menu on the NetMan and then on the tab Remote Hosts, you should see the following page (You may have to click on the VMware tab).

Once you are on this screen you should be able to enable VMware shutdown this will allow you to configure your server applications to shut down. (Please note that up to 10 hosts or vCentre server appliances can be shut down). You can set priorities and delays for each application depending on your requirements. The validation of credentials are checked periodically and if invalid an alarm will be issued.

Enable ESXi shutdown

Enable the ESXi shutdown service.

Hostname or IP address

Enter the delay between entries of the table.

After mains failure

The shutdown will be executed after the set minutes of delay after mains failure.

When autonomy is below (per cent)

The shutdown will be executed when autonomy is below the set per cent.

Then, UPS shutdown after

Enable and set seconds delay to shut down the UPS as well.

To configure VM power-on and/or shut down priority the VCSA or ESXi configuration must be used:

Use this option when you need the delay of the virtual machine to be different than the default delay for all machines. The settings that you configure for individual virtual machines override the default settings for all machines.

a) To change the startup order of virtual machines, select one from the Manual Startup category and use the up arrow to move it up to Automatic Startup or Any Order.

b) Use the up and down arrows to change the startup order for virtual machines in the Automatic Startup category. During the shutdown, the virtual machines shut down in the reverse order.

b) Click Start delay behaviour, select Use specified settings, and configure the startup delay before the next virtual machine in the sequence is powered on.

d) Click Stop delay behaviour, select Use specified settings, and configure the shutdown action and delay.
