6 TROUBLESHOOTING FOR NETWORK CONNECTIONS
104 Locating the Equipment in the Network
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

problem:
