I cannot locate the equipment in the network.
Corrective Action
Improper settings may cause problems in locating the equipment in the network. Try the checklist below to detect the
cause of the problem. If the problem remains unsolved, contact your service representative.
No. Check...
1 Is the startup page printed out? If not, wait until
the communication comes online. Examine the
protocol settings listed on the startup page. Are
they correct?
2 Print out a configuration page. Make sure that
there are not any discrepancies or inconsistencies
between the current network settings and your
network environment. Change the network
settings, if necessary. Use the Find Computer
utility from your Windows computer to locate the
equipment by its device name. Can you find the
equipment?
3 Can you locate other computers connected to the
same network?
4 Check the link LED activity on the hub and/or NIC
of the equipment and the client machine. Do the
hardware components appear to be functioning
properly?
5 Confirm whether the Ethernet cable is normal.
Does the current Ethernet speed appear on the
ETHERNET setting screen ([USER FUNCTIONS]
- [ADMIN] - [NETWORK] - [ETHERNET]) ?
Furthermore, confirm whether the hub you are
using supports FULL mode. Does the hub support
its mode ?
6 Make sure that the device name for the
equipment is unique and verify that the WINS
and/or DNS server database are not causing
potential naming conflicts with the network
settings on the equipment. If necessary, change
the network settings on the equipment. After the
communication comes back online, can you see
the equipment in the network?
7 If the network environment is using complex
subnet or supernet structures, is the IP address
used by the equipment within the network
structures range of valid addresses?
