CHAPTER 5: Troubleshooting
Should problems develop during the installation or operation of your
9-Port Personal MiniHub, this chapter should help to locate, identify and
correct such problems. Please follow the suggestions listed in
Section 5.1
below. If nothing helps, contact your supplier; see
Section 5.2
.
5.1 Things to Check
1. If you a problem installing or operating the 9-Port Personal MiniHub,
refer back to
Chapters 3 and 4
. Check to make sure that the various
other components of the network are operable.
2. Check the attached cables to ensure that they have RJ-45-type
connectors (not RJ-11 “telephone” type), that the cables have been
properly connected, and that the cables/wires have not been crimped
or damaged during installation.
3. Make sure that the DC-power cord is properly attached to the
MiniHub, and that the external power supply is plugged into a
functioning electrical outlet. Use the PWR LED to verify that the unit
is receiving proper power.
4. If the problem is isolated to a network device other than the 9-Port
Personal MiniHub, we recommended that you replace the problem
device with a known-good device. Verify whether or not the problem
goes away. If not, go to Step 5 below. If the problem goes away, the
Personal Hub and its associated cables are functioning properly.
5. If the problem persists, contact your supplier for technical support.
