Replacement Instructions
Remove any of the optional modules that you have installed into your hub
before returning it to Hewlett-Packard. Keep the optional modules to install
them into the replacement hub.
The modules can be damaged easily by small amounts of static electricity.
Observe these precautions when removing and installing the modules:
When handling the module, first touch a grounded metal surface, or
wear an anti-static wrist strap that is attached to grounded metal.
To prevent generating static electricity, minimize your movement
around the work area, or work in an anti-static work area.
Handle the module carefully at all times. Avoid flexing it or touching
its components.
The faulty hub should be returned to Hewlett-Packard with the AUI/Xcvr
and management slots empty and the cover plates installed.
For information about how to remove the modules, see the manuals
accompanying the HP Transceiver Module and the HP AdvanceStack 8U/16U
SNMP Module.
