OIR events occur on Cisco 3600 series routers

Core Issue

Online Insertion and Removal (OIR) of network modules is not supported on Cisco 3620 and 3640 series routers. A drop in output voltage from the power supply is reported as an OIR event. Such events on the Cisco 3620 and 3640 series typically indicate a hardware problem. Although the Cisco 3660 series does have limited support for OIR, spurious OIR events that occur without the physical insertion or removal of a network module can also indicate a problem with the hardware.

Resolution

These are possible causes for a spurious OIR event on a Cisco 3600 series router:

  • A mis-seated network module.
  • A power supply problem.
  • A network module hardware failure.
  • A chassis slot/backplane failure.

To further clarify the cause, refer to Troubleshooting OIR Events on Cisco 3600 Series Routers.

When hardware replacement is indicated after troubleshooting:

  • If you have a hardware support contract directly with Cisco for this part, use the Service Order Submit Tool to request a replacement part directly.
  • For warranty service, contact the Cisco Technical Assistance Center (TAC) directly at 1-800-553-2447, or online by using the TAC Service Request Tool.
  • If your product is not covered by contract or warranty, contact your Cisco partner or reseller to request a replacement part for the hardware component that is causing the issue.
