Be sure the switch is powered up.
Check network cabling between the management station and
the switch.
Check that you have a valid network connection to the switch
and that the port you are using has not been disabled.
Be sure you have configured the VLAN interface through
which the management station is connected with a valid IP
address, subnet mask and default gateway.
Be sure the management station has an IP address in the
same subnet as the switch's IP interface to which it is
connected.
If you are trying to connect to the switch via the IP address
for a tagged VLAN group, your management station, and the
ports connecting intermediate switches in the network, must
be configured with the appropriate tag.
If you cannot connect using Telnet, you may have exceeded
the maximum number of concurrent Telnet/SSH sessions
permitted. Try connecting again at a later time.
If you cannot connect using SSH, you may have exceeded
the maximum number of concurrent Telnet/SSH sessions
permitted. Try connecting again at a later time.
Be sure the control parameters for the SSH server are
properly configured on the switch, and that the SSH client
software is properly configured on the management station.
Be sure you have generated a public key on the switch, and
exported this key to the SSH client.
Be sure you have set up an account on the switch for each
SSH user, including user name, authentication level, and
password.
Be sure you have imported the client's public key to the
switch (if public key authentication is used).
Be sure you have set the terminal emulator program to
VT100 compatible, 8 data bits, 1 stop bit, no parity, and the
baud rate set to 115200 bps.
Check that the null-modem serial cable conforms to the pin-
out connections provided in the Installation Guide.
