3.7 Power Button
• POWER
The POWER button is used to shut down (when on battery power) or place the unit in standby (when on mains power). Since
the unit has an internal UPS when the unit is in standby it will still charge the battery. It is normal that the fan continues to run in
standby mode.
When the power LED flashes it means that the unit has detected the loss of mains power and it is running on battery back-
up. Depending on the load conditions regarding Power over Ethernet on the front three network ports, the unit should run for
approximately 30 to 40 minutes on battery. When the unit is running off battery back-up it monitors the network link status and
DMX inputs and will auto shut off if there is no activity after a predetermined period of time. The feature prevents the battery
from being depleted should the power be removed when the show shuts down.
3.8 Clear Settings Feature
The R4 has a feature to enable all settings to be reset to factory default. The procedure to clear the settings is to hold down buttons
NET1, NET2 and NET3 simultaneously and also while keeping the net buttons held down then press and hold the ChamNet
button. The R4 will then reboot and factory default settings will be restored.
3.9 Special Mode Feature
Note
This is a newer feature, please ensure firmware version >= v210 is installed.
Holding down the DMX button for 5 seconds will cause R4 to enter special mode selection. One or more of the NET buttons
can then be used to enable or disable extended DMX feature. During special mode selection the DMX button LED will flash.

Once the required special mode has been selected pressing the DMX button again will save the feature to flash and the selected
feature will become immediately active. The unit will then return to regular frontpanel function.
3.10 Power Over Ethernet (PoE)
The SnakeSys R4 contains a fully isolated and standards compliant Power over Ethernet system. PoE output source is available
on the front three network sockets by plugging in a PoE compliant network device.
