Problem 4: You are unable to start a local management session on the
management module.
Solutions: Try the following:
❒
Verify that the RS-232 Serial Management Cable is securely
connected to the RS-232 Terminal port on the module and to the port
on the terminal or personal computer.
❒
Verify that the communications settings for the RS-232 port on the
terminal or personal computer are set correctly. For the settings of the
RS-232 Terminal port, refer to Chapter 22, “Starting a Local
Management Session” on page 143.
Problem 5: A network cable is connected to the 10/100/1000Base-T
Management port and the port’s Link/Activity LED is on, but you are
unable to start a remote Telnet or SSH management session with the
management module.
Solution: Try the following:
❒
Start a local management session on the management module and,
using the AT-S97 Management Software, verify that the management
module has an IP address configuration. For instructions on how to
assign an IP address configuration to the management module, refer
to the AT-S85 and AT-S97 Management Software Command Line
Interface User’s Guide.
❒
If your remote workstation is not a member of the same network as the
management module, verify that the IP address configuration on the
module includes a default gateway. This is the IP address of the
routing interface of the first hop to reaching the remote network where
your management workstation is a member. The default gateway’s IP
address must be a member of the same network as the management
module.
