How to connect to the UPS via direct connection
Contents
Introduction
During a new installation of the UPS, some customers are required to place the UPS on the network, which will require to set an IP address for the unit. In order to do this, it will first be required to login into the UPS. This procedure will help in directly connecting to the UPS via direct connection from laptop. From the factory the NMC defaults to DHCP and HTTPS connection. If you are connected to a network with a DHCP server, the NMC automatically receives an IP address. If there is no DHCP server, the NMC will assign an IP (Auto IP). The Auto IP
address will be a link-local IP address.
Purpose
To place the UPS on the network, it is first required to login into the UPS. This will be achieved by directly connecting to the UPS via direct connection from a laptop.Requirements
1. Any laptop which has an ethernet port.
2. RJ45 cable
3. UPS that has a network module.
Procedure
- Type network connections into Windows Search and select View network connections.
2. Right-click Ethernet and select Properties.
3.Select Internet Protocol (TCP/IP) Version 4 (you may need to scroll down). Then click the Properties button.
4. If not already selected, select the Obtain an IP address radio button and the Obtain DNS server address automatically radio button.
5. Click OK to accept the configuration.
6. Connect the NMC network connection directly to the PC’s Ethernet port using a patch cable.
7. Power the NMC unit.
8. Wait 10 seconds.
9. Open a web browser on the PC.
10. In web browser address bar, type https://169.254.254.1, and press <Enter>. A Privacy Error or an error explaining that the certificate (cert) authority is invalid may be displayed. This message is presented when a device has the initial certificate in-use. You may proceed as this error is expected.
Troubleshooting
If the browser does not connect, the device may have older firmware. Try again with the following additional steps:
1. The MAC address of the NMC is printed on a label on the face plate of the card. Get the last two bytes of the MAC address.
Example: if the label shows 00:0F:9C: 03:07:83, use 0783
2. From the Start menu, Run cmd.exe. Type the following commands but replace the number with the last two bytes of the MAC address from the following step.
set m=0783
set /a h="0x%m% % 256 + 1" && set /a l=0x%m% / 256 % 256
echo 169.254.%h%.%l%
3. Open a web browser on the PC.
4. In web browser address bar, type https://<ip address>, replacing <ip address> with the address previously calculated.
example: https://169.254.132.7/
