The Web browser cannot access the Switch over the network.
Ensure that, if you are managing the Switch over the network, remote
access to the management software of the Switch is enabled. For more
information, see
Enabling and Disabling Remote Access.
The Web browser can no longer access the Switch over the
network.
Ensure that:
Remote access to the management software of the Switch is
enabled. For more information, see
Enabling and Disabling
Remote Access.
The port through which you are trying to access the Switch is
enabled. For more information, see
The Device View, or if the
port is enabled, check the connections and network cabling for
the port.
The port through which you are trying to manage the Switch
belongs to the management VLAN. This is the VLAN that can be
used to access the management software of the Switch.
Trusted IP Host may be configured to restrict the IP addresses
which are allowed to access the unit.
If there is still a problem, try accessing the Switch through a different
port. If you can now access the Switch, a problem may have occurred
with the original port. Contact your supplier for further advice.
You forget the password for the "admin" user account and can no
longer perform important management operations.
Use the password recovery method outlined below to define a new
password for the "admin" user account:
1. Access the Command Line Interface and enter the user name
"recover" and password "recover" to place the Switch in password
recovery mode. The Switch remains in password recovery mode
for a maximum of 30 seconds, before it returns to the CLI login
prompt.
2. Perform a hard reset on the Switch whilst it is in password
recovery mode by switching it off, waiting a few seconds, and
switching it on again.
If the Switch has a Redundant Power Supply (RPS) connected,
you will need to disconnect it in order to perform a hard reset.
You cannot use a soft reset operation to reset the password
of the "admin" user account. This will end the password recovery
procedure and return you to the CLI login prompt.
3. When the Switch has rebooted following the hard reset enter a
new password for the "admin" user account.
4. Enter enable to leave password recovery enabled. You are now
logged in as the default "admin" user.
