Chassis Traps
The chassis-related traps are defined under the
jnxTrapsandjnxChassisOKtrapsbranches. For the system logging severity levels for these traps, see Juniper Networks Enterprise-Specific SNMP Traps.These traps are defined as follows:
- Power failure (
jnxPowerSupplyFailure)—When the power supply, router circuit breaker, or power circuit fails, or when there is a power outage. If only one of the power supplies in the router fails, the service impact is minimal. One power supply can provide the necessary power for a fully loaded router. To determine the source of the failure, you must physically inspect the router.- Fan failure (
jnxFanFailure)—When the fan fuse blows or when the fan wiring shorts out. If only one fan has failed, there is no service impact. The remaining fans increase speed to compensate. However, you must resolve the problem before another fan fails. To determine the source of the failure, you must physically inspect the router, taking care to check the fuses. See the hardware installation guide for your router model for more information.- Overtemperature (
jnxOverTemperature)—When several fans fail or the room temperature increases significantly. The service impact of this trap depends on the temperature of the router. In general, the router increases the speed of the fans when any component exceeds a temperature of 55 the higher speed until the temperature decreases below the threshold. In this case, there is no service impact. However, if the temperature exceeds 75 the router transmits a warning and automatically shuts down. This scenario creates a significant service impact because the shutdown affects additional routers and equipment. To determine the source of the overtemperature problem, you must physically inspect the router to determine whether any fans have failed in the router.- Power Supply OK (
jnxPowerSupplyOK)—Sent when a power supply recovers from failure.- Fan OK (
jnxFanOK)—Sent when a fan recovers from failure.- Temperature OK (
jnxTemperatureOK)—Sent when a chassis component recovers from an overtemperature condition.- Redundancy Switchover (
jnxRedundancySwitchover)—For certain platforms, such as the M20 or M160, some subsystems, such as the Routing Engine, have a redundant backup unit that can be brought online, manually or automatically, if the main unit malfunctions. The redundancy switchover trap indicates such a change.- Field Replaceable Unit Removal (
jnxFruRemoval)—Sent when the specified FRU has been removed from the chassis.- Field Replaceable Unit Insertion (
jnxFruInsertion)—Sent when the specified FRU has been inserted into the chassis.- Field Replaceable Unit Power Off (
jnxFruIPoweroff)—Sent when the specified FRU has been powered off in the chassis.- Field Replaceable Unit Power On (
jnxFruPowerOn)—Sent when the specified FRU has been powered on in the chassis.For more information on chassis MIB traps, see Standard SNMP Traps and Juniper Networks Enterprise-Specific SNMP Traps.
