Fixing Double-Bit Errors

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
To fix a double-bit error:
1
Remove the second SRP module, if there is one.
2
Reboot 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.
