v. Configuring the Q53 on Your Network
Troubleshooting Tips
•
Have you confirmed the network connection to the Q53 is working correctly?
Trying different network cables and locations will help narrow down the problem.
Cannot ping the Q53
There are a number of possible reasons for this:
•
Have you restarted the Q53? Sometimes this will solve various communication
problems.
•
Is the network cable securely connected?
•
Have you checked your network connection to the Q53? Try it at a new location on
your network if possible or swap in another device.
•
Have you made an entry in your computer’s host table (
/etc/hosts
,
host nis
map, or
DNS name table) for the Q53?
•
Have you tried to
ping
with the IP address instead of the IP name? This will
eliminate any name-lookup issues and focus more on the communications between
the Q53 and your host.
•
Is it possible that a duplicate IP address has been assigned?
•
Did you use the correct netmask for your particular environment?
•
Has the Q53 been moved from another network? If so, it will likely need to be
reconfigured to integrate with its new location. This includes at minimum a new IP
address and netmask. Please see
on page 66 for
possible configuration methods.
•
Is there a router between the Q53 and your host? If so, a default router or a static
route must be configured on the unit so the Q53 knows how to get its response back
to the originating host. Please see
•
Do you have a DHCP or BOOTP server running on your network? By default, the
Q53 comes with the DHCP and BOOTP request turned
on
so although you may
have stored a particular network configuration in the unit’s EEPROM, a DHCP or
BOOTP server may supply new
network
parameters upon bootup. To turn off
DHCP and BOOTP on the unit, please see
Configure the Q53 IP address and
If none of these help, try the following:
•
Reset the unit to default settings. Please see
66. Once the unit is in the default state, use one of the configuration options listed in
the "Q53 Configuration" above in the manual to reconfigure it.
Cannot Telnet to the Q53
If you are unable to
ping
the Q53 as well, please see
on page 29. If
it is
telnet
only that you are having problems with, these points should be considered:
•
Are you able to
telnet
to another host on your network or
telnet
from another host?
If not, look into your host’s TELNET configuration.
