34.9. Chassis Parameters
Figure 34.35. Chassis Parameters Menu
This menu displays the chassis temperature and, if hardware version 2, the voltage levels of chassis
power supplies and a record of the last power down time. The system will highlight red any out-of-
range value. The monitored values are described below:
Parameter Description
temp Motherboard temperature
VcoreA, VCoreB Redundant 3.3V power supply voltages
+3.3 PS1, +3.3 PS2 Redundant 3.3V power supply voltages
+5V 5V power supply voltage
+12V 12V power supply voltage
VBat Battery voltage
Table 34.2.
The last power down time reflects the time power was removed from the chassis as a result of a power
failure, commanded reboot or an watchdog initiated reboot.
System alarms will be generated for out-of-range parameters and watchdog initiated reboots.
34.10. Power over Ethernet
The IEEE 802.3af standard describes a method known commonly as PoE (Power over Ethernet),
for providing electrical power over the twisted pair wiring most commonly used in Ethernet networks.
The obvious benefit is the ability to take advantage of previously unused copper in the 10/100Base-
T wiring configuration to provide power without requiring that new wiring be installed.
RuggedRouter can be provisioned to supply power according to IEEE standard 802.3af. In order to
provide PoE via all four RuggedRouter Ethernet ports, the unit must be provisioned with a PoE power
supply in place of the optional redundant power supply. RuggedRouter implements PoE mode A,
supplying up to 400mA at up to 48V on pins 3 and 6 (T568A pair 2) and return on pins 1 and 2 (T568A
pair 3).
