CHAPTER 8 Troubleshooting
If ECC detects a double-bit error in a system that contains a redundant SRP module, the redundant module becomes active and the system continues to operate. However, you must still troubleshoot the SRP module with the double-bit error. If ECC detects a double-bit error in a system that does not contain a redundant SRP module, you must troubleshoot the SRP module immediately. See Fixing Double-Bit Errors.
Fixing Double-Bit Errors
To fix a double-bit error:
1Remove the second SRP module, if there is one.
2Reboot the system with the board reset button on the SRP module (see Figure 1-8).
These actions attempt to correct a transient double-bit error. However, if the console displays a memory test failure for the SRP module after you reboot, or if the FAIL LED on the SRP module stays on during rebooting, the SDRAM is permanently damaged and needs replacing. In this event, call Juniper Networks Customer Service to arrange for repair.
