7.0 DOWNLOADING FIRMWARE UPDATES
This section explains how to update the unit’s firmware.
1. The first step is to download the upgrade text file. To do this, visit Liebert’s Web site at
http://www.liebert.com and go to the OpenComms EM section. Or contact Liebert Monitoring
Application Support at 1-800-222-5877. The firmware upgrade files are named with the model
name, firmware version number and the extension “.txt” as follows:
• The filename for the EM Controller is em-x.x.txt, where x.x is the firmware version number.
• The filename for the EM PDU Controller is empdu-x.x.txt, where x.x is the firmware version
number.
• The filename for the vEM-14 Controller is vem-14-x.x.txt, where x.x is the firmware version
number.
2. Connect the unit to your network using an Ethernet cable or crossover cable (see 2.3.2 - Connect
to an Ethernet Network).
3. Make sure the permission to upgrade is set to Allowed (see 5.7 - Sys Info Window).
4. Open a communications program such as HyperTerminal.
(One way to do this in Windows is to click on the Start button, then on Programs, then
Accessories, then Communications and finally HyperTerminal.)
5. Create a new connection in HyperTerminal.
6. When prompted, enter a name for the new connection and click OK. This opens the Connect To
window.
7. In the Connect To window:
a. Select TCP/IP (Winsock) as the type of connection in the Connect Using box. After TCP/IP is
selected, the Host Address and Port Number boxes appear in the window.
b. In the Host Address box, enter the IP address of the OpenComms EM.
c. In the Port Number box, enter 3001.
8. This should allow you to connect to the unit. The status area at the bottom left corner of the
HyperTerminal window will display Connected and the amount of time you have been
connected.
9. Click the Transfer tab at the top of the HyperTerminal window, then select Send Text File.
10. In the Send Text File window, specify the location of the firmware text file, then click Open.
Several dots will appear across the HyperTerminal screen, indicating that it is checking for
errors. Then it will begin downloading the file to the unit.
11. When the download is complete, a message appears and the status area changes to
Disconnected. At this point, you may close the HyperTerminal program by clicking on the
File
menu, then on Exit.
If you have not saved the connection created in Step 5, a prompt message will ask whether you
wish to do so.
12. After downloading a firmware update to the unit, you must wait about one minute before
disconnecting power from the unit.
!
CAUTION
When the firmware is updated, all settings except the network configuration are lost.
NOTE
Steps 4 through 11 must be done on the same network segment where the OpenComms EM is
connected.
NOTE
The following instructions refer to the Microsoft

HyperTerminal program. These
steps may vary for other communications programs.
