During system diagnostic testing, the system is completely under the control of the diagnostic software. All hardware components are
verified, and results are displayed on the console. In cases where a failure is detected, results and corrective actions will be displayed. After
the system diagnostic testing is complete, the system exits from the diagnostic mode and reloads the system for normal operation.
System diagnostic testing runs at link speeds of 10 Gbps or 40 Gbps (for MOD2 QSFP+ data uplink ports) or 40 Gbps (for
MOD3/MOD4 QSFP+ stacking ports) depending on the speed of the link being tested and the type of port.
Monitoring power and cooling
If the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and use the
show chassis command to verify that the temperature is below the shutdown threshold. If you still cannot isolate the problem, then the
internal power supply may be defective. In this case, contact Ruckus Technical Support for assistance.
The device contains temperature sensors that the software reads based on a configurable device poll time. The device has two automatic
speed fan control settings based on the temperature. To protect the device from overheating, the following temperature threshold levels
exist:
•
The warning level is the temperature at which the device generates a syslog message. It is configurable up to 100°C (212°F).
•
The shutdown level is the temperature at which the device reboots. It is set by the device and is not configurable. When the
device temperature reaches the shutdown level, it generates a warning message that the device’s temperature is over the
shutdown level and the device shuts down in two minutes. The system restarts 120 seconds after the device reaches the
temperature shutdown level.
The switch fans have two speeds, low and high. The fan speed settings are set by the device, and are not configurable. During system
bootup, the fans run at high speed. After bootup, the fans operate at low speed when the temperature of the switch is below the high limit
temperature that is specified in the following table. If the switch reaches the high limit temperature, the fans operate at high speed until the
switch reaches the low limit temperature specified in the table, at which time the fans decrease to low speed. If the switch reaches or
exceeds the critical (shutdown) temperature for two minutes, the switch shuts down.
NOTE
In addition to the overall temperature of the device, the PoE-supported models monitor the temperature of the Power over
Ethernet (PoE) power supply unit (PSU). When the low limit and high limit temperatures are reached, the PoE PSU fans change
speed using the same algorithm as the module fans. There is no change to the Critical (shutdown) temperature value for these
modules.
