IN-BAND ACCESS

In-Band Access

You can access the management agent in the switch from anywhere within the attached network using Telnet, a Web browser, or other network management software tools. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address. Also, be sure the port through which you are connecting to the switch has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the switch.

Caution: The management agent can accept up to four simultaneous Telnet sessions. If the maximum number of sessions already exists, an additional Telnet connection will not be able to log into the system.

Stack Troubleshooting

If a stack fails to initialize or function, first check the following items:

Check that all stacking cables are properly connected.

Check if any stacking cables appear damaged.

Check that one Stack Master button is pressed in.

Check that no more than one Stack Master button is pressed in.

Check that all switches in the stack are powered on.

After checking all items, reboot all the switches in the stack.

The switches allow you to configure ring- or line-topology stacking. When using ring-topology stacking configuration and a switch fails, or a stacking
