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...
Yes
No
Corrective Action
1
Is SNMP enabled on the equipment?
Next Step
Enable the SNMP (MIB).
2
Are the SNMP setting of the equipment and that of the
software the same?
Next Step
SNMP V1/V2: Check if the community names of the
equipment and the software are the same.
SNMP V3: Check if each item of the SNMP setting of the
equipment and the software is 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.
Next Step
See the vendor’s website for information about product
updates and technical supports.
4
Print an NIC Configuration page from the equipment.
Does the equipment support the same protocol as the
network?
Next Step
Configure the proper protocol.
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?
End
Next Step
6
Check the NIC Configuration page. Are the IP address
and subnet mask settings correct?
Next Step
Setup the TCP/IP settings correctly.
7
Check the router to make sure that it is not filtering out
the equipment packets. Is the router processing
equipment packets correctly?
Next Step
Adjust the router settings.
8
Can another computer within the same network segment
discover the equipment?
Next Step
See the following section to fix the problem:
P.36 "Locating the Equipment in the Network"
9
Check the NIC Configuration page. Is the Unit Serial
Number part of the device name?
Next Step
Contact your dealer.
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.
