Remove the second SRP module, if there is one.
1.
Reboot the system with the module reset button on the primary SRP module. (See
2.
Figure 9 on page 10.)
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.
