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. When 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” on page 115.
Fixing Double-Bit Errors
To fix a double-bit error:
1. Remove the second SRP module, if there is one.
2. Reboot the system with the module reset button on the primary SRP module.
(See Figure 9.)
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.
