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.
Note: The management agent accepts 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 the Master button is pressed in on only one switch.
•
Check that the Stack button is pressed in on all switches.
•
Check that all switches in the stack are powered on.
After checking all items, reboot all the switches in the stack.
The switch allows you to configure ring- or line-topology stacking. When
using ring-topology stacking configuration and a switch fails, or a stacking
cable is disconnected, the entire stack reboots and resumes normal
operation using line-topology stacking through the remaining stack
connections. Also, any changes to the stack including powering down of a
unit or the insertion of a unit causes the stack to reboot.
