6.TROUBLESHOOTING FOR NETWORK CONNECTIONS
Cannot locate the equipment with Local Discovery
Problem Description
Local Discovery cannot detect the equipment.
Corrective Action
The equipment is normally located automatically by SNMP. When the TWAIN driver, File Downloader, Address Book
Viewer, Backup/Restore Utility, Remote Scan driver, N/W-Fax driver or printer driver cannot automatically discover the
equipment over the network, the most likely cause is limitations of the protocols supported by the computer. In some
cases, you need to add or update network components; however, first see the checklist below to fix the problem.
No. Check...
1
Is SNMP enabled on the equipment?
2
Are the SNMP setting of the equipment and that
of the software the same?
3
Confirm that the protocol suite installed on the
client computer has been updated with the latest
software for the given operating system. If your
network only supports the IPX/SPX protocol,
make sure that the most current version of Novell
Client software is installed.
4
Print an NIC Configuration page from the
equipment. Does the equipment support the same
protocol as the network?
5
Change the protocol settings from TopAccess, if
necessary, and reboot the equipment for the
changes to take effect. Repeat step 2. Was the
device discovered?
6
Check the NIC Configuration page. Are the IP
address and subnet mask settings correct?
7
Check the router to make sure that it is not
filtering out the equipment packets. Is the router
processing equipment packets correctly?
8
Can another computer within the same network
segment discover the equipment?
9
Check the NIC Configuration page. Is the Unit
Serial Number part of the device name?
10
Check link activities on the port being used by the
equipment and the integrity of the network cable,
hub, or switch that connects the equipment to the
network. Replace any network components that
you can tell or suspect are faulty.
