Setup and Configuration Issues
The following issues relate to setup and configuration problems.
Lost Password
If you lost your password, you must reset the unit to the default settings. See
. The default
password is
public
.
If you record your password, keep it in a safe place.
The Unit Responds Slowly
If the unit takes a long time to become available, it could mean that:
• No DHCP server is available.
• The IP address of the unit is already in use.
Verify that the IP address is assigned only to the unit. Do this by switching off the unit and then pinging the IP address.
If there is a response to the ping, another device in the network is using the same IP address. If the unit uses a static
IP address, switching to DHCP mode could remedy this problem. Also see
Setting the IP Address with ScanTool
.
• There is too much network traffic.
Web Interface Does Not Work
If you cannot connect to the unit Web server through the network:
1. Connect a computer to the serial port of the unit and check the HTTP status. The HTTP status can restrict HTTP
access at different interfaces. For more information, see “Serial Port” in the
Tsunami QuickBridge.11 Reference
Manual
.
2. Open a command prompt window and enter:
ping <ip address unit>
(for example
ping 10.0.0.1
)
•
If the unit does not respond, ensure that you have the correct IP address.
•
If the unit responds, the Ethernet connection is working properly; continue with this procedure.
3. Ensure that you are using one of the following Web browsers:
•
Microsoft Internet Explorer version 5.0 or later (Version 6.0 or later recommended)
•
Netscape version 6.0 or later
4. Ensure that you are not using a proxy server for the connection with your Web browser.
5. Ensure that you have not exceeded the maximum number of Web Interface sessions.
Command Line Interface Does Not Work
If you cannot connect to the unit through the network:
1. Connect a computer to the serial port of the unit and check the SNMP table. The SNMP table can restrict telnet or
HTTP access. For more information, see “Serial Port” in the
Tsunami QuickBridge.11 Reference Manual
.
2. Open a command prompt window and enter:
ping
<ip address unit>
(for example
ping 10.0.0.1
).
•
If the unit does not respond, ensure that you have the correct IP address.
•
If the unit responds, the Ethernet connection is working properly; continue with this procedure.
3. Ensure that you have not exceeded the maximum number of CLI sessions.
TFTP Server Does Not Work
With TFTP, you can transfer files to and from the unit. Also see
. If a TFTP server is not properly
configured and running, you cannot upload and download files. The TFTP server:
