5.0 TROUBLESHOOTING
All Magnum Ethernet products are designed to provide
reliability and consistently high performance in all network
environments. The installation of Personal Hubs is a simple
procedure (see Section 3.0, INSTALLATION); operation is very
simple and is described in Section 4.0, OPERATION.
Should problems develop during installation or operation,
this section should help to locate, identify and correct such problems.
Please follow the suggestions listed below prior to contacting your
supplier. However, if you are unsure of any procedure described in
this section, or if the Magnum Personal Hub is not operating as
expected, do not attempt to repair or alter the unit. Contact your
supplier (or if unknown, contact Garrett Communications) for
assistance.
5.1 Before Calling for Assistance
1. If difficulty is encountered when installing or operating the
Personal Hub, refer back to Section 3.0, Installation and Section 4.0,
Operation. Check to make sure that the various other components of
the network are operable.
2. Check the cables and connectors to ensure that they are of
the RJ-45 type (not RJ-11 “telephone” type), have been properly
connected, and the cables/wires have not been crimped or in some
way impaired during installation.
3. Make sure that the DC power cord is properly attached to
the unit, and that the external power supply unit is plugged into a
functioning electrical outlet. Use the PWR LEDs to verify the unit is
receiving proper power.
4. If the problem is isolated to a network device other than the
Magnum Personal Hub, it is recommended that the problem device
be replaced with a known good device. Verify whether or not the
problem is corrected. If not, go to Step 5 below. If the problem is
corrected, the Personal Hub and its associated cables are functioning
properly.
5. If the problem continues after completing Step 4 above,
contact your supplier of the Personal Hub unit (or if unknown,
contact Garrett Communications) by fax, phone or email for
assistance.
