CCESS
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.

ROUBLESHOOTING
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 only 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.
Switches in the stack may be configured using a ring- or line-topology. To ensure
minimal disruption in case a unit or stacking cable fails, always use a
ringtopology. When using ring-topology configuration and a switch fails, or a
stacking cable is disconnected, the stack continues normal operation using
linetopology stacking through the remaining stack connections.

AUTION
:
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.
