NOTE: The primary SRP module illuminates the REDUNDANT LED only when the
SRP modu
le detects a secondary or standby SRP module online. The standby SRP
module monitors an activity signal from the primary SRP module to determine its
state; it does not shadow the operations of the primary SRP module.
IfthestandbySRPmoduledetectsthattheprimarySRPmoduleisnotactive(and
high-a
vailability mode is not enabled), it reboots the system and takes control. If
high-availability mode has been enabled, automatic switchover occurs with near
hitless failover. (ERX-7xx and ERX-14xx models only)
