Troubleshooting a Network Switch Module

Problem
• System cannot communicate with the network
• Network cable connections
• Network switch module and hub configuration settings
Action
NOTE: To eliminate the possibility of a hardware problem with the module or its attaching devices, first ensure that
the module is properly initialized and configured. See the Configuration Guide and the documentation that came
with the module before performing the following procedure.
1
Check the appropriate indicator on the network switch module. See "I/O Connectivity" on page28 for
a description the indicators for each type of network switch module.
• If the link indicator displays an error condition, check all cable connections.
See "I/O Connectivity" on page 28 for the link indicator error conditions for your particular
network switch module.
• Try another connector on the external switch or hub.
• If the activity indicator does not light, replace the network switch module. See "Chassis I/O
Module" on page 70.
2
If the server module requires a daughter card for a particular network switch module, ensure that the
appropriate daughter card is installed. If so, reseat the daughter card. See "I/O Module Daughter Card"
on page82.
If the network link indicator on the server module is green, then the server module has a valid link to
the appropriate network switch module.
3
Ensure that the appropriate drivers are installed and the protocols are bound.
