Problems During Bootup

The following section describes problems you might encounter during Power On Self-Test (POST) or during bootup and explains how to resolve those problems.

Problem: Router failed the onboard memory test.

Solution: When this failure occurs, it means the internal CPU memory failed. Replace the router to correct the problem.

Problem: System hangs at Loading Bridge during Flash Loader Menu.

Solution: Reflash the firmware to ensure you are using the latest version. See Upgrading Firmware on page 3-31. If you cannot update the firmware or if the updated firmware does not correct the problem, replace the router.

Problem: One of the POST diagnostic tests failed.

Solution: Use the information in Table 4-1 to find solutions to a particular diagnostic failure. First confirm any failure you may encounter by running the individual test from the Diagnostics menu. See Using the Loader Diagnostics Menu on page 4-6.
