Installation Problems
By carefully following the installation procedures described in chapter 1,
"Installing the Hub", you can avoid most problems caused by improper
installation of the hub or one of its components.
Incorrect Hardware Installation
Incorrectly installing the hub, ac power cord, power supply, the HP Ad-
vanceStack 8U/16U SNMP Module, or a transceiver module can result in one
or all of these components malfunctioning or not functioning at all. If one or
all of these components appear to not be functioning, re-check the installa-
tion procedure and, if necessary, re-install the component correctly.
Cabling Problems
A high percentage of network problems are due to faulty cabling. Cabling
problems usually result in the failure of a hub to connect to a network,
another hub, or the end nodes.
Connections
All cables attached to the hub should be checked to see that they are
properly connected. Proper network connections are described in chapter 1,
"Installing the Hub".
Properly connecting cables to the transceiver modules is described in the
documentation that accompanies those modules.
If you are using the optional HP ThinLAN Transceiver Module, be certain
that the thin coax segment attached to the port is properly terminated with
a 50-ohm terminator at both ends, as described in the manual accompanying
the transceiver module.
