C. Try to “PING” the Supply
The Ping utility verifies the computer can send a message and get a response from the
power supply over the network
On a Windows XP computer, open a command line window by:
1. Click the “Start” button, Select “Run…”
2. A “Run” window opens. Type:
cmd
<Enter>. See the command window open
3. Type
“
ping <IP address>
” (IP from the supply front panel, see section 4.2).
Verify the ping packets had successful responses
If the “ping” does not get responses from the power supply, then there is a mismatch
between the power supply and the computer LAN settings. Also, the ping function may
be disabled in the power supply (see section 5.5.4). In this case, do a power supply
“LAN Reset” (see section 4.2) and try to connect again
D. Check the Computer LAN Settings
The computer LAN settings must be compatible with the power supply LAN settings
Since the default power supply setting is “DHCP/Auto-IP” (after doing a “LAN Reset”),
the computer’s network card should have the same setting
Refer to your operating system instructions on configuring the TCP/IP connection for
DHCP (also called, “Obtain an IP address automatically”)
3.8. OTHER TROUBLESHOOTING
3.8.1. Cannot Connect using Hostname
If the power supply’s IP address is set to “static IP”, you can not use the hostname address
To use the hostname address, the NetBIOS naming service must be running in your
computer or network server (shown below in the Windows XP “Local Area Connection
Properties”)
If the power supply has a static address or the computer is
not
running NetBIOS, then
hostname addressing may be used if you edit the “hosts” file in the network server.
In Windows XP, see the text file
“C:\WINDOWS\system32\drivers\etc\hosts”
3.8.2. Cannot View Web Pages Over a Peer-to-Peer Network
If there is no gateway to a network, verify the proxy server is disabled in the web browser.
With Microsoft Internet Explorer, open the browser and, on the toolbar, navigate:
“Tools”
‡
“Internet Options…”
‡
“Connections”
‡
“LAN Settings…”
and see the windows open:
Verify the “Proxy server” checkbox is
NOT
checked
