Troubleshooting
Router-Specific
Problems
When you first install the Edge Router module in an ONline or ONcore hub
the Cisco engine runs a full set of hardware diagnostic tests. If the engine
fails diagnostics, the Router (RTR) LED does not illuminate or will flash. This
indicates a problem with the router hardware or software. Refer to the
appropriate Cisco Systems troubleshooting documentation for corrective
action.
Troubleshooting
Mailbox Interface
Problems
ONline and ONcore Edge Routers use a hardware mailbox interface that
allows the Cisco engine to communicate with the 3Com carrier board
during powerup. If the 3Com mailbox does not establish communication
with the engine, the following message is reported to the engine console
port:
%MAILBOX-3-INITFAIL:Mailbox initialization failure.
Not getting interrupts. Mailbox offline.
If you see this message, contact your 3Com representative for assistance.
Troubleshooting
3Com Carrier
Problems
Before mailbox communication is initialized and established between the
Cisco engine and the 3Com carrier, the Module Status (S) LED on the front
panel of the Edge Router module blinks slowly. If communication is
established successfully, the Status LED illuminates and stays on solid. If the
Status LED does not light, the 3Com carrier board has malfunctioned.
Contact your 3Com representative for assistance. Refer to Appendix B for
instructions on contacting Technical Support for you product.
