I cannot
access the
switch using
Telnet.
Make sure the ports are properly connected.
You may have exceeded the maximum number of concurrent Telnet sessions. Close
other Telnet session(s) or try connecting again later.
Check that you have enabled Telnet service access. If you have configured a secured
client IP address, your computer’s IP address must match it. Refer to the chapter on
access control for details.
I cannot

The administrator username is “admin”. The default administrator password is “1234”.
The username and password are case-sensitive. Make sure that you enter the correct
password and username using the proper casing. If you have changed the password

restores all of the factory defaults including the password.

client IP address, your computer’s IP address must match it. Refer to the chapter on

MAC address).
In Windows, use arp -d at the command prompt to delete all entries in your computer’s
ARP table.
