INSTALLATION PROBLEMS
This chapter explains how to isolate and solve problems
that may occur when you install the OfficeConnect NIC.
Basic Troubleshooting Tips
If you have trouble installing your OfficeConnect NIC, or if
the installation failed (as described in “Verifying Successful
Installation” in Chapter 3), follow these basic
troubleshooting tips.
CAUTION: Before inserting or removing the NIC from
your PC, turn the power off to the PC and unplug the
power cord.
■ Check the NIC installation by reviewing Chapter 2.
Make sure that the NIC is seated correctly in an
appropriate expansion slot. Check for specific hardware
problems, such as loose or broken connections.
■ Inspect all cables and connections. Check the length
and rating of the cable. Make sure that the cable and
its length comply with 10BASE-T or 100BASE-TX
recommendations. See Table 3 in Chapter 2 or
Appendix A for more information.
■ Make sure that you’re running the latest BIOS for your
PC. If your BIOS hasn’t been upgraded in the previous
12 months, contact your PC manufacturer to obtain
the current version of your BIOS software.
■ Run the NIC self-tests and the Echo test, as described
later in this chapter.
■ Download the latest OfficeConnect NIC driver from the
3Com World Wide Web site and install it in your PC.
Run the NIC self-tests and the Echo test again, using
the same option settings as those used on the failed
NIC. If the tests still fail, the NIC may be defective.
