Problem 3: A network cable is connected to the 10/100/
1000Base-T Management port, but the port’s Link/Activity
LED is off.
Solutions: Try the following:
Verify the network device connected to the Management
port is powered on and operating properly.
Verify the twisted pair cable is securely connected to the
port on the management module and on the remote
network device.
Verify you are using the correct type of cable for the port
and have not exceeded the maximum length. For cable
specifications, refer to “Cable Requirements” on
page 42.
Try connecting another network device to the twisted
pair port with a different cable. If the twisted pair port is
able to establish a link, then the problem is with the
cable or the other network device.
Problem 4: 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.
Solutions: Try the following:
Start a local management session on the management
module and, using the AT-S97 Management Software,
verify the management module has an IP configuration.
For instructions, 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 the IP
configuration on the module includes a default gateway.
The gateway is the IP address of a 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
subnetwork as the management module.
