Solving Problems With the Serial Web Utility 8-7
The SNMP Network Manager can no longer access the stack.
Check that:
■
Remote access to the management software of the stack has not
been disabled. For more information, see “Enabling and Disabling
Remote Access to the Stack” on page 5-16.
■
The port through which you are trying to access the stack has not
been disabled. For more information, see “Viewing the Status of the
Ports” on page 4-12 or If it is enabled, check the connections and
network cabling for the port.
If there is still a problem, try accessing the stack through a different
port. If you can now access the stack, a problem may have occurred
with the original port. Contact your supplier for further advice.
Solving Problems
With the Serial
Web Utility
You cannot connect to the web interface of the Switch.
Check that:
■
The Switch is powered-up.
■
You are using a proper null modem cable. Pin-outs are detailed in
“Pin-outs” on page D-1.
■
The flow control and line speed (baud rate) settings are the same on
the Switch and on the management workstation:
■
You have not changed the line speed setting of the management
workstation after the Switch has connected (the Switch only
configures its line speed the first time it connects).
■
You have selected the correct serial port on your management
workstation.
You can change some of the settings for the management workstation
using the
Advanced Configuration Parameters
dialog box. To display this,
select the Serial Web Setup program item in the Serial Web program
group.
