OprHighTh

Table 1: Alarm Details

Parameter	Description
Code	oprHighTh
Description	Optical Power Received Above High Threshold: The optical power received is above the high threshold.
Entities Affected	Optical channel interfaces (see respective table below). OTN OTU interfaces (see respective table below). Ethernet interfaces (see respective table below). SONET/SDH interfaces (see respective table below). Wavelength channels (see respective table below).
Possible Causes	There is inadequate attenuation on the optical connection to signal source. The output power on the remote optical transmitter is too high.
Default Severity	Major
Service Affecting	No (false).
Alarm Clearing	See Clearing an OprHighTh alarm.
Related Fault Hierarchy	See Common fault hierarchy - OTN and CBR ports.

¹ Reporting of this alarm for a wavelength channel is supported only on multiwavelength CFP transceivers.

Note: Follow all applicable safety requirements as described in the BTI7800 Series Hardware Overview and Installation Guide.

Retrieve detailed information for the interface to determine whether the value of the Optical Power Rx counter is within the range indicated by the Optical Power Received Minimum Threshold and Optical Power Received Maximum Threshold values.
