For information about this alarm or condition, refer to the “Alarm Troubleshooting” chapter in the
Cisco ONS 15454 DWDM Troubleshooting Guide. That guide discusses all DWDM alarms.
2.7.57 EHIBATVG
Default Severity: Major (MJ), Service-Affecting (SA)
SONET Logical Object: PWR
The Extreme High Voltage Battery alarm occurs in a –48 VDC environment when a battery lead input
voltage exceeds the extreme high power threshold.
This preset value is approximately -56 VDC for the Cisco ONS 15310-CL hardware platforms versions
800-24012-08 and before and approximately -58 VDC for versions 800-24012-09 and later. Also, the
extreme high voltage batter value is approximately -54 VDC for CTX version of the Cisco ONS 15310-
MA hardware versions 800-23879-04 and before and is approximately -58 VDC for CTX version of the
Cisco ONS 15310-MA hardware version 800-23879-05 and later. The alarm is raised until the voltage
remains under the threshold for 120 seconds.
Clear the EHIBATVG Alarm
Step 1 The problem is external to the ONS 15310-CL or ONS 15310-MA. Troubleshoot the power source
supplying the battery leads.
Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call Cisco TAC (1-800-553-2447) in order to report a Service-Affecting (SA)
problem.
2.7.58 ELWBATVG
Default Severity: Major (MJ), Service-Affecting (SA)
SONET Logical Object: PWR
The Extreme Low Voltage Battery alarm occurs in a –48 VDC environment when a battery lead input
voltage falls below the extreme low power threshold. This threshold has a preset value of –40 VDC and
is not user-provisionable. The alarm remains raised until the voltage remains over the threshold for
120 seconds.
Clear the ELWBATVG Alarm
Step 1 The problem is external to the ONS 15310-CL or ONS 15310-MA. Troubleshoot the power source
supplying the battery leads.
