Alarms

This chapter describes how to view system-level alarms for the Cisco ONS 15200 network using the Maintenance Manager application, including alarms specific to the selected Client Layer Interface Port (CLIP) module, all alarms recorded by the system, and all events recorded by the system.

4.1 Clip Active Alarms Screen

The Clip Active Alarms screen provides a list of active alarms for the selected CLIP module (Figure 4-1). This screen has four columns: Area, Name, Status, and Description. Table 4-1 describes each of the columns on the Clip Active Alarms screen and lists the possible values.

Table 4-1: Clip Active Alarms Screen Columns

Parameter	Definition
Area	Displays the label under which the alarm occurs. In most cases this is the name of the parameter that generated the alarm.
Name	Displays the type of alarm.
Status	Displays the severity of the alarm: Yellow—Warning Red—Critical or major alarm
Description	Displays the system descriptor for the alarm: lowwarning highwarning lowalarm highalarm minor major critical alarm raised power1_fail power2_fail uninit warning unidentified incomplete

Table 4-2 describes the alarms that could appear in the Name column.

Table 4-2: Environment Parameter Definitions

Alarm Name (Area)	Definition	Alarm Type (Name)
DWDM_ARXPOWER (protected channels only)	Indicates that the power input from the A side of the ONS 15200 network is outside the acceptable power range.	Status
DWDM_BRXPOWER (protected channels only)	Indicates that the power input from the B side of the ONS 15200 network is outside the acceptable power range.	Status
DWDM_RXPOWER (non-protected channels only)	Indicates that the power input from the ONS 15200 network is outside the acceptable power range.	Status
DWDM_PELTIERCURRENT	Indicates that the Peltier current of the selected CLIP module is outside the acceptable power range.	Status
DWDM_FDI	Indicates that the selected CLIP module has received an FDI alarm from the NE upstream.	—
DWDM_LOC	If the selected CLIP module is protected, it indicates that the CLIP has lost input power on the A and B sides. If the selected CLIP module is unprotected, it indicates that the CLIP has lost input power.	—
DWDM_LASERTEMP	Indicates that the temperature of the laser transmitting to the ONS 15200 network is outside the acceptable temperature range.	Status
CLIENT_RXPOWER	Indicates that the power input from the client equipment is outside the acceptable power range.	Status
CLIENT_LASERTEMP	Indicates that the temperature of the laser transmitting to the client equipment is outside the acceptable temperature range.	Status
CLIENT_LASERBIAS	Displays the value of the current component added to the modulation current in order to obtain a proper operating point for the laser.	—
DWDM_LASERBIAS	Displays the value of the current component added to the modulation current in order to obtain a proper operating point for the laser.	—
BOARD_TEMP	Indicates that the temperature on the surface of the CLIP module circuit board is outside the acceptable temperature range.	Status
BOARD_POWER	Indicates that the power of the CLIP module circuit board is outside the acceptable range.	Status
DCN_QPPA (protected channels only)	Indicates an error on the internal datacom link on the A side of the network.	—
DCN_QPPB (protected channels only)	Indicates an error on the internal datacom link on the B side of the network.	—
DCN_QPP (non-protected channels only)	Indicates an error on the network's internal datacom link.	—
DCN_CAN	Indicates an error on the Control Area Network (CAN) bus.	—
POWER1	Indicates that the primary power input is outside the acceptable range.	Status
POWER2	Indicates that the secondary power input is outside the acceptable range.	Status
MISC_DAC	Indicates a hardware fault relating to the digital/analog converter (DAC) has occurred.	—
MISC_FLASH	Indicates a hardware fault relating to the eeprom has occurred.	—
MISC_INSTRUCTION	Indicates an entity is trying to write to an unavailable position.	—

4.2 System Active Alarms Screen

The System Active Alarms screen (Figure 4-2) displays alarms recorded for all modules installed on the network. The System Active Alarms screen has five columns: CLIP, Area, Name, Status, and Description. Table 4-3 describes the columns on the System Active Alarms screen and lists the possible values.

Table 4-3: System Active Alarms Screen Parameters

Parameter	Definition
CLIP	Displays the number of the CLIP module that generated the alarm.
Area	Displays the label where the alarm occurs. In most cases this is the name of the parameter that generated the alarm.
Name	Displays the type of alarm.
Status	Displays the severity of the alarm: Yellow—Minor alarm or warning Red—Critical or major alarm
Description	Displays the system descriptor for the alarm: lowwarning highwarning lowalarm highalarm alarm major critical alarm raised power1_fail power2_fail uninit warning unidentified incomplete

4.3 System Event Log

The system Event Log displays a list of events that have occurred in all modules included in the system (Figure 4-3).
