Chapter 2 Alarm Troubleshooting

Alarm Procedures

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).

2.7.106 HIBATVG

Default Severity: Major (MJ), Service-Affecting (SA) for ONS 15310-CL

SONET Logical Object: PWR

The High Voltage Battery alarm occurs in a –48 VDC environment for the ONS 15310-CL platform

when a battery lead input voltage exceeds the high power threshold. This threshold has a preset value of

–55 VDC and is not user-provisionable. The alarm remains raised until the voltage remains under the

threshold for 120 seconds.

Clear the HIBATVG Alarm

Step 1 The problem is external to the ONS 15310-CL. 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.

2.7.107 HI-LASERBIAS

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Objects: EQPT, OCN

DWDM Logical Object: PPM

The Equipment High Transmit Laser Bias Current alarm is raised against OCN port laser performance.

The alarm indicates that the card laser has reached the maximum laser bias tolerance.

Laser bias typically starts at about 30 percent of the manufacturer maximum laser bias specification and

increases as the laser ages. If the HI-LASERBIAS alarm threshold is set at 100 percent of the maximum,

the laser usability has ended. If the threshold is set at 90 percent of the maximum, the card is still usable

for several weeks or months before it needs to be replaced.

Clear the HI-LASERBIAS Alarm

Step 1 Complete the “Physically Replace a Card” procedure on page 2-163 for the controller card

(15310-CL-CTX or CTX2500 card).

Caution Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this,

perform an external switch if a switch has not already occurred. See the “2.10.1 Protection Switching,

Lock Initiation, and Clearing” section on page 2-156 for commonly used traffic-switching procedures.
