    This topic describes the chassis component alarm conditions on EX9200 switches.

    Table 1 lists the alarms that the chassis components can generate on EX9200 Switches.

    Chassis Component

    Alarm Condition

    Remedy

    Alarm Severity

    Air filters

    Change air filter.

    Change air filter.

    Yellow

    Alternative media

    The router boots from an alternate boot device, the hard disk. The CompactFlash card is typically the primary boot device. The Routing Engine boots from the hard disk when the primary boot device fails.

    Open a support case using the Case Manager link at http://www.juniper.net/support/ or call 1-888-314-5822 (toll free, US & Canada) or 1-408-745-9500 (from outside the United States).

    Yellow

    Craft interface

    The craft interface has failed.

    Replace failed craft interface.

    Red

    Line Cards

    A line card is offline.

    Check the line card. Remove and reinsert the line card. If this fails, replace failed card.

    Yellow

    A line card has failed.

    Replace failed line card.

    Red

    A line card has been removed.

    Insert line card into empty slot.

    Red

    Modular Interface Cards (MICs)

    A MIC is offline.

    Check the MIC. Remove and reinsert the MIC. If this fails, replace failed card.

    Yellow

    A MIC has failed.

    Replace failed MIC.

    Red

    A MIC has been removed.

    Insert MIC into empty slot.

    Red

    Fan trays

    A fan tray has been removed from the chassis.

    Install missing fan tray.

    Red

    One fan in the chassis is not spinning or is spinning below required speed.

    Replace fan tray.

    Red

    A higher-cooling capacity fan tray is required when an MPC is installed on the chassis.

    Upgrade to a high-capacity fan tray.

    Yellow

    Host subsystem

    A host subsystem has been removed.

    Insert host subsystem into empty slot.

    Yellow

    A host subsystem has failed.

    Replace failed host subsystem.

    Red

    Hot swapping

    Too many hot-swap interrupts are occurring. This message generally indicates that a hardware component that plugs into the router’s backplane from the front (generally, an FPC) is broken.

    Replace failed component.

    Red

    Power supplies

    A power supply has been removed from the chassis.

    Insert power supply into empty slot.

    Yellow

    A power supply has a high temperature.

    Replace failed power supply or power entry module.

    Red

    A power supply input has failed.

    Check power supply input connection.

    Red

    A power supply output has failed.

    Check power supply output connection.

    Red

    A power supply has failed.

    Replace failed power supply.

    Red

    Invalid AC power supply configuration.

    When two AC power supplies are installed, insert one power supply into an odd-numbered slot and the other power supply into an even-numbered slot.

    Red

    Invalid DC power supply configuration.

    When two DC power supplies are installed, insert one power supply into an odd-numbered slot and the other power supply into an even-numbered slot.

    Red

    Mix of AC and DC power supplies.

    Do not mix AC and DC power supplies. For DC power, remove the AC power supply. For AC power, remove the DC power supply.

    Red

    Not enough power supplies.

    Install an additional power supply.

    Red

    Switch Fabric Module (SF module)

    An SF module has been removed.

    Insert SF module into empty slot.

    Yellow

    An SF module has failed.

    Replace failed SF module.

    Red

    Routing Engine

    Excessive framing errors on console port.

    An excessive framing error alarm is triggered when the default framing error threshold of 20 errors per second on a serial port is exceeded.

    This might be caused by a faulty serial console port cable connected to the device.

    Replace the serial cable connected to the device.

    If the cable is replaced and no excessive framing errors are detected within 5 minutes from the last detected framing error, the alarm is cleared automatically.

    Yellow

    Error in reading or writing hard disk.

    Reformat hard disk and install bootable image. If this fails, replace failed Routing Engine.

    Yellow

    Error in reading or writing CompactFlash card.

    Reformat CompactFlash card and install bootable image. If this fails, replace failed Routing Engine.

    Yellow

    System booted from default backup Routing Engine. If you manually switched mastership, ignore this alarm condition.

    Install bootable image on default master Routing Engine. If this fails, replace failed Routing Engine.

    Yellow

    System booted from hard disk.

    Install bootable image on CompactFlash card. If this fails, replace failed Routing Engine.

    Yellow

    CompactFlash card missing in boot list.

    Replace failed Routing Engine.

    Red

    Hard disk missing in boot list.

    Replace failed Routing Engine.

    Red

    Routing Engine failed to boot.

    Replace failed Routing Engine.

    Red

    The Ethernet management interface (fxp0 or em0) on the Routing Engine is down.

    • Check the interface cable connection.
    • Reboot the system.

    Backup Routing Engine Alarms

    For routers with master and backup Routing Engines, a master Routing Engine can generate alarms for events that occur on a backup Routing Engine. Table 2 lists chassis alarms generated for a backup Routing Engine.

    Note: Because the failure occurs on the backup Routing Engine, alarm severity for some events (such as Ethernet interface failures) is yellow instead of red.

    Note: For information about configuring redundant Routing Engines, see the Junos OS High Availability Library for Routing Devices.
