TX Matrix Chassis and Interface Alarm Messages Overview

 

TX Matrix Chassis and Interface Alarm Messages Description

When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on the craft interface as appropriate, trips the corresponding alarm relay contact on the TX-CIP, and reports the cause of the alarm in the craft interface LED display. To view a more detailed description of the alarm cause, issue the show chassis alarms scc CLI command:

user@host> show chassis alarms scc

To display all alarms in the routing matrix, issue the show chassis alarms command without the scc option.

TX Matrix Chassis Alarm Messages

TX Matrix chassis alarms Indicate a problem with a TX Matrix chassis component such as the cooling system or power supplies, as described in Table 1.

Note

The text in the column labeled ”Craft Interface Message” appears in the display of the craft interface. The text in the column labeled “CLI Message” appears in the output from the show chassis alarms command.

T640 Router Alarm Messages

T640 router alarms indicate a problem with a T640 router (LCC) in the routing matrix, as described in Table 2. For a list of additional alarm messages that apply only to the T640 router, see the T640 Core Router Hardware Guide.

Note

The text in the column labeled ”Craft Interface Message” appears in the display of the craft interface. The text in the column labeled “CLI Message” appears in the output from the show chassis alarms command.

SONET/SDH Interface Alarm Messages

Interface alarms indicate a problem with a specific network interface. For example, Table 3 lists the alarm messages for a SONET/SDH interface. These messages apply only to a T640 router in a routing matrix. For more information about interface alarms, see the T640 Core Router Interface Module Reference.

Note

The text in the column labeled ”Craft Interface Message” appears in the display of the craft interface. The text in the column labeled “CLI Message” appears in the output from the show chassis alarms command.
