Conditions for Replacing a Switch Module
The following hardware conditions indicate that the switch module needs to be
replaced:
• The annunciator on the front panel remains off. This condition indicates that a
hardware reset is ac tive or that the module is not receiving +5 volt power.
• The annunciator remains amber. This condition indicates that the module has
failed to boot.
For information about using LEDs to troubleshoot an EtherSpeed switch module,
see Appendix C, “LEDs.”
For information about troubleshooting other System 500x modules, refer to the
using guide for the specific module.
Note: The Model 5625HD switch module communicates through the MCP
rather than the common management bus (CMB). Modules without the CMB
interface do not display on the Slot Selection menu, and there is no way to
verify that they are connected to the backplane using the service port menus.
