Problem
Corrective steps
Pinging the unit IP address fails.
1. Verify that your PC and unit share the same IP network.
2. Launch SysLog server.
3. Turn off the unit and then turn it back on. Wait for the SysLog message #0 to
appear, reporting the unit IP address.
Unit can be pinged from a local host,
but when trying to use the unit’s ping
utility there is no response.
1. Turn off the host firewall.
2. If ping is okay, go to the advanced firewall options and enable the ping option,
TFTP (UDP port 69) and SNMP trap ports (UDP port 162).
Software cannot be updated via TFTP.
1. Use the unit ping utility to ping the host running the TFTP server application.
2. Turn off the firewall or enable UDP port 69.
3. Verify that the appropriate update file package was copied to the root folder
of the TFTP server.
Log on to the unit by SSH works, but
SSH session terminates after a while.
SSH session terminates after three minutes if no key is pressed and no activity takes place.
No SNMP trap events are received.
1. View the unit configuration using a web browser.
2. Verify that
SNMP
is selected.
3. Verify that the remote SNMP manager IP matches.
4. Verify that the trap community string matches the remote SNMP manager
trap configuration.
5. Turn off the firewall on the SNMP manager station or allow UDP port 162 to
pass through it.
SysLog server IP is properly set, but
log messages are not received.
Turn off the host firewall or allow UDP port 514 to pass through it.
Logging in to the unit does not work
since RADIUS/ was enabled.
1. Follow instructions in

to enabled.
