1   Contents of This Document

This document describes alarm conditions and their probable causes in the SmartEdge chassis and in controller cards, carrier cards, line cards, media interface cards (MICs), and their ports.

Note:  
In the following descriptions, the term controller card refers to any version of the Cross-Connect Route Processor (XCRP) Controller card (XCRP4), unless otherwise noted.

The term controller carrier card refers to the controller functions on the circuit board within the SmartEdge 100 chassis. The term I/O carrier card refers to the line card functions on the circuit board; these functions are compatible with the similar functions that are implemented on all SmartEdge 400 and SmartEdge 800 line cards.


Note:  
Alarm severities conform to the definitions provided in Generic Requirements, GR-474-CORE, Issue 1, December 1997, Network Maintenance: Alarm and Control for Network Elements.

The term replaceable unit is a generic description of a component (fan, power supply, controller card, controller carrier card, I/O carrier card, and others) with an alarm that cannot be resolved for the current unit. Because only SmartEdge 100 MICs and small form-factor plug-capable (SFP) transceivers are replaceable in a SmartEdge 100 chassis, the resolution of an alarm for any other SmartEdge 100 component requires that you replace the SmartEdge 100 chassis.

5   SSE Alarms

Faults are reported separately for SSE cards, SSE disks, SSE groups, and partitions. See Table 8, Table 9, Table 10, and Table 11 for alarm descriptions.

You can configure the threshold for low-partition-space alarms using the following command in SSE partition configuration mode:

alarm low-partition-space raise-at raise_percentage clear-at clear_percentage

Verify card- and disk-level alarms using the show hardware slot detail command. Verify group- and partition-level alarms using the show sse group group_name detail command.

(1)  Probable causes: a) The disk does not have enough space to create the partition; b) Another partition of the same name but with a different size already exists on the disk from a previous configuration. Solution: Use the delete partition command to free up disk space or remove the existing partition, or use the format sse command to remove all user-configured partitions on the disk. The format sse command can only be run on an SSE card that is not bound to any SSE group.

6   Port and Channel Alarms

This section provides tables of alarms for the following types of ports.

6.1   Optical ATM, POS, and Channelized Optical Port Alarms

The tables in this section apply to ports on the ATM OC line cards and MICs and Packet over SONET/SDH (POS), channelized OC-12, and STM-1 line cards.

Note:  
If a major or critical alarm occurs on an ATM or a POS port and that port is a member of an Automatic Protection Switching (APS) group, either as a protected or a working port, the alarm is downgraded to a minor alarm because the service is protected by the redundant port. The severity levels in the table are the default levels, not the degraded levels.
