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 3-37 . 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: Contact Chaparral technical support.

Caution:
Do not remove the router’s cover. The router has no user-
serviceable parts. Removing the cover will void the warranty.
