TABLE 47 Displaying alarm log information (continued)
Description
To display all alarms in the alarm log related to a specific management module (where n, module
number is 1-3 for MLX/XMR and 1 for CER/CES) and all alarms for it's subsystems.
To display all alarms in the alarm log related to temperature information for a management module
(where n, module number is 1-3 for MLX/XMR and 1 for CER/CES)and a specific fan (where x, is
the temperature device number).
To display all alarms in the alarm log for all interface modules and subsystems for the management
module.
To display all alarms in the alarm log related to a specific interface module(where n, module number
is 1-3 for MLX/XMR and 1 for CER/CES) and all alarms for it's subsystems.
To display all alarms in the alarm log related to subsystem information for an interface module
(where n, module number is 1-3 for MLX/XMR and 1 for CER/CES)
and either all events on a specific subsystem, or events for a particular subsystem(where subsystem
is temperature or optic)(where x, is a the device number).
To display all alarms in the alarm log for all SFM and subsystems for the SFM.
To display all alarms in the alarm log related to a specific SFM(where n, is SFM slot 1-8 for MLX/
XMR) and all alarms for it's subsystems.
To display all alarms in the alarm log related to SFM information for a specific SFM(where n, is SFM
slot 1-8 for MLX/XMR)
and either all events on a specific subsystem, or events for a particular subsystem(where subsystem
is temperature or fabric-element)(where x is 1-4 for a fabric element device number).
Management and interface modules
When a management module or interface module is removed from the chassis, a major level alarm is generated in the alarm history log.
If the management module, interface module, or SFM is powered off, a critical level alarm is generated in the alarm history log.
When a module is removed or powered off, alarms for all subsystems of the module are cleared from the current alarm log. If a module is
removed from the chassis, all alarms are cleared from the current alarm log, and memory associated to its subsystems is freed. When a
module is added to the configuration, memory is reallocated.
Temperature
If temperature on the management module or interface module increases to the highest threshold, a major alarm is set. If temperature
decreases below the highest threshold, the alarm is cleared from the current alarm log, and an additional alarm is sent to the alarm
history log stating that the condition has been removed. If the temperature increases into shutdown range, a critical level alarm is reported
and logged in the alarm logs.
Optics
Alarms and warnings are monitored only for optic devices that support optical monitoring. If optical monitoring is disabled, then no
alarms are generated.
