Clear The Lpbkterminal (Ocn) Condition; Lwbatvg; Clear The Lwbatvg Alarm; Man-Req - Cisco ONS 15310-CL Troubleshooting Manual

Chapter 1 Alarm Troubleshooting
Performing a loopback on an in-service circuit is Service-Affecting (SA). If you did not perform a
Note
lockout or Force switch to protect traffic, the LPBKTERMINAL condition can also be accompanied by
a more serious alarm such as LOS.
For information about troubleshooting electrical circuits with loopbacks, refer to the
Points of Failure on an Electrical Circuit Path" section on page
"1.3 Identify Points of Failure on an OC-N Circuit Path" section on page

1.7.163 LWBATVG

The Low Voltage Battery alarm occurs in a –48 VDC environment for an ONS 15310-CL when a battery
lead input voltage falls below the low power threshold. This threshold has a preset value of –44 VDC
and is not user-provisionable. The alarm remains raised until the voltage remains above the threshold for
120 seconds. (For information about changing this threshold, refer to the "Turn Up Node" chapter in the
Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.)
