Tracing a Route
To determine the path through which a device can reach another device, enter a command similar to the following at any level of the CLI on the
device.
device> traceroute 10.33.4.7
The CLI displays trace route information for each hop as soon as the information is received. Traceroute requests display all responses to a given
TTL. In addition, if there are multiple equal-cost routes to the destination, the device displays up to two responses by default.
Digital Optical Monitoring
You can configure your device to monitor optical transceivers in the system, either globally or by specified port. When digital optical monitoring is
enabled, the system monitors the temperature and signal power levels for the optical transceivers in the specified ports. Console messages and
syslog messages are sent when optical operating conditions fall below or rise above the SFP and SFP+ manufacturer’s recommended thresholds. For
more information about digital optical monitoring, refer to the RUCKUS FastIron Monitoring Configuration Guide.
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.
