Helpful Hints
Consider the following hints:
❑
Install the master module in slot 1, if possible. The master cannot
manage hubs above it. Make sure you connect the master module into
the backplane before all other modules.
❑
When powering up hub modules in the chassis, always start with the
master.
❑
Use the Omega menus or SNMP to diagnose problems that occur.
❑
Always quit your Omega sessions when you are done. If a hub’s error
condition prevents you from using Omega, that is, Omega hangs,
follow the procedures to reset the faulty module.
❑
If you cannot use Omega, it is possible that your hub is still
functioning as a repeater. Try reloading the firmware if this hub is
your master module.
❑
Make sure you are using the latest version of the firmware. Use the
Omega diagnostics menu to obtain the version number. ATI Technical
Support can verify if you have the latest version number.
❑
Call ATI Technical Support for problems you cannot resolve or to
initiate a Return Material Authorization (RMA).
Resetting a Malfunctioning Hub Module
When a module’s fault light stays on, reset the module by performing the
following steps:
1. Select Quit from the main Omega menu, if you can; otherwise, proceed to
the next step.
2. Undo the chassis screws and slide the faulty hub module out far enough to
disengage it from the backplane.
3. Unplug the power cord from the malfunctioning hub module and wait five
seconds.
4. Plug in the power cord again.
5. Reseat the module in the backplane connector.
Even if the fault light still stays on after the reset, the unit’s repeater function
is restored and only the management software is malfunctioning.
