Standby OLT Optic Status Configuration
The system checks the RX power of standby OLT every 2 seconds in order to ascertain
whether to be connected to ONU normally by its optic fiber. (However, in case that any
activated ONUs are not connected to working OLT, the system can not check whether the
standby OLT is linked to ONU normally or not, because a standby OLT cannot detect the
RX power.) When the RX power of standby OLT is detected, it reports the information to
SFU in order to notify the system.
To perform a switchover automatically under the certain condition except for a manual
switchover, the link status of standby OLT should be under "RX Detect" condition.
Basically, TX power of standby OLT is disabled in order not to affect working OLT. But you
can enable the TX power temporarily to check whether the standby OLT operates normal-
ly or not, for the reason of replacing the board or SFP module, etc.
Be cautious when you enable the TX power of standby OLT, because it may cause prob-
lems for ONUs in service.
To configure the TX power of standby OLT, use the following command.
Command

Description
olt redundancy standby-optic
enable group GROUP-ID
<1-600>
Global

dancy group for the specified time. After the specified
time period, TX power is automatically disabled.

enable group GROUP-ID perma-
nent

If the system is in detecting the RX power of the standby OLT normally, the user-input
