If the answer to your question is not in this table, read the IP configuration
and diagnostic test information on the next pages.
IP Configuration Errors
If you are using IP communications, make sure your IP configuration param-
eters are set properly for all segments in use. Use the ASCII console’s IP
Configuration function as described in chapter 3. Incorrect IP configuration
on the hub will prevent it from communicating with the network management
station, and may cause other network problems.
In particular, make sure you provide the hub with a unique IP address, and
that you use the correct subnet mask for your network. See appendix D,
“Network Addressing”, for more information.
I think the active Management Module
isn’t working anymore because the
Fault LED is on. I don’t have a redundant
Management Module in the stack.
What do I do?
Attempt to reset the stack by pressing the reset
button on the Management Module.
If the problem still occurs, download a current
or new firmware version from the web, BBS, or
CompuServe. See the perforated card at the
beginning of this manual for more instructions.
If that doesn’t work, call HP for a replacement
module. When the module arrives, only power
down the hub with the faulty Management
Module. The rest of the hubs in the stack will
retain their configuration as long as they
continue to receive power.
