The Health and Power page monitors the temperature status, power supply status and fan
status on all relevant devices. Depending on the model, there are one or more fans on a device.
Some models have no fans at all.
Redundant Power
This feature is only supported on the SG550 series.
The RPS 2300 is a backup for AC power. It is used for supplying power to the device if the AC
power supply stops working. It is only supported on the 550 family.
If it becomes necessary to switch to the backup power, the device changes between the power
sources without reboot and without any disruption to the device operation. The device polls
the RPS status every 1 sec, if RPS is providing power, the RPS LED is set, and if the RPS is
active, a SYSLOG is generated.
When main power supply is again operational, the devices notifies the RPS to stop providing
power. A SYSLOG is generated.
The RPS LED (on the device front panel) displays the current RPS status:
• Off – RPS is not connected
• Green (solid) – RPS is ready
• Amber (blinking) – RPS is currently supplying power to the device
• Amber (solid) – RPS is connected but providing power to two other devices. In this
case, the RPS will not be able to provide power to the current device, while providing
power to the two other devices.
