Status LEDs

g013768

NOTE: The primary SRP module illuminates the REDUNDANT LED only when the SRP module 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.

If the standby SRP module detects that the primary SRP module is not active (and high-availability 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)
