TROUBLESHOOTING
Described below are some common troubleshooting steps and
solutions. If following the troubleshooting guide does not solve the
problem, please contact Technical Support for further assistance.
Switching Issues
Commanding the unit remotely to switch does not cause the unit
to switch.
•
Check that the Remote Connection is still active. In SSH
sessions, query the unit to see if a response is received.
•
Consider disconnecting and attempting to reconnect to ensure
that the Remote is still accessible.
Remote Connection Issues
An SSH session with the unit cannot be opened.
•
Check that the physical connections are correct. See section
“Remote Ethernet Connections” on page 12 for more
information.
•
Check that the IP address settings have been configured
properly. See section “10/100BASE-T LAN Setup” on page 13
for more information.
•
Ensure that the SSH port being used is correct. Note that the
default port numbers are 22 and 10001.
•
Check that no other users are currently connected to the switch
remotely. If another Remote Control SSH tunnel or logged in
GUI session is active, new connections will not be established.
An IP address is not being assigned or the unit is unreachable.
•
By default, the unit is configured for DHCP. If the unit cannot
obtain an IP address from a DHCP server within the first
minutes after booting, the unit will assign itself an IP address via
BOOTP.
•
If this is the case, it will be necessary to use DeviceInstaller
using the “Assign IP Address” feature to force the refresh by
resetting it to DHCP (or any other desired setting).
•
While the unit is already connected to a network with a DHCP
server, power cycling the unit will solve the problem as well.
•
Press the Reset button on the rear panel.
•
If the problem persists, there may be other network issues.
Make sure there are no MAC address filters on the DHCP
server or any other part in the network that would prevent this
unit from connecting. If such filters exist, they must either be
