All the known bugs are listed in the release note. Read the release note before you set up the switch. Contact Customer Support if these suggestions do not resolve the problem.
1.1 Diagnosing problems using IP utilities
1.1.1 Ping
Ping is a command you can use to check whether your PC can recognize other computers on your network and the Internet. A ping command sends a message to the computer you specify. If the computer receives the message, it sends messages in reply. To use it, you must know the IP address of the computer with which you are trying to communicate.
On Windows-based computers, you can execute a ping command from the Start menu. Click the Start button, and then click Run. In the Open text box, type a statement such as the following:
ping 192.168.1.1
You can substitute any private IP address on your LAN or a public IP address for an Internet site, if known.
If the target computer receives the message, a Command Prompt window appears as shown.
Using the ping utility
If the target computer cannot be located, you will receive the message “Request timed out.”
Using the ping command, you can test whether the path to the switch is working (using the pre-configured default LAN IP address 192.168.1.1) or another address you assigned.
You can also test whether access to the Internet is working by typing an external address, such as that for www.yahoo.com (216.115.108.243). If you do not know the IP address of a particular Internet location, you can use the nslookup command, as explained in the following section.
From most other IP-enabled operating systems, you can execute the same command at a command prompt or through a system administration utility.
1.1.2 nslookup
You can use the nslookup command to determine the I P address associated with an Internet site name. You specify the common name, and the nslookup command looks up the name on your DNS server (usually located with your ISP). If that name is not an entry in your ISP’s DNS table, the request is then referred to another higher-level server, and so on, until the entry is found. The server then returns the associated I P address.
On Windows-based computers, you can execute the nslookup command from the Start menu. Click the Start button, then click Run. In the Open text box, type the following:
nslookup
A Command Prompt window displays with a bracket prompt (>). At the prompt, type the name of the Internet address you are interested in, such as www.absnews.com.
The window displays the associate IP address, if known, appears as shown.
There may be several addresses associated with an Internet name. This is common for web sites that receive heavy traffic; they use multiple, redundant servers to carry the same information.
To exit from the nslookup utility, type exit and press <Enter> at the command prompt.
1.2 Simple fixes
The following table lists some common problems that you may encounter when installing or using the switch, and the suggested actions to solve the problems.
FREQUENTLY ASKED QUESTIONS:
1. Power LED does not light up after the switch is turned on.
Verify if the power cord is securely connected to the switch and a wall socket/power strip.
2. 1000Mbps LED does not illuminate after an Ethernet cable is attached.
Verify if the Ethernet cable is securely connected to your LAN switch/hub/PC and to the switch.
Make sure the PC and/or hub/switch is turned on.
Some equipment does not support 1000Mbps. In this case, it is normal for the !000Mbps LED to be out.
3. PC cannot access another host in the same network.
Check that the Ethernet cabling is good and the LED is green.
If the port LED is amber, check if this port is disabled. You may
need to wait a minute if you just turned on the switch.
4. PCs cannot display web configuration pages.
The switch is powered up and the connecting port is enabled. The factory default IP for the switch is 192.168.1.1.
Verify your network setup in your PC for this information.
5. You forgot/lost your WEB Configuration password.
If you have not changed the password from the default, try using “Asante” as the password.
Login to console mode through RS232 or USB, use “sys user show” to display the lost information.
6. Some pages do not display completely
Verify that you are using Internet Explorer v5.5 or later. Netscape is not supported. Support for Javascript® must be enabled in your browser. Support for Java® may also be required.
Ping the switch IP address to see if the link is stable. If some ping packets fail, check your network setup to make sure a valid setting.
7. Changes not saved
Make sure you have gone to Admin – Save configuration and saved the configuration.
8. Cannot show the texts on the terminal emulator.
The factory default baud rate is 9600, no flow control, 8 bit data, no parity check and stop bit is one.
Check if the cable is good.
