2.6 Device ventilation
Fig. 6 - Fan location
There are ventilation openings on the device side panels that serve to remove heat. There are two fans on the
inside of the side panel (highlighted on Fig. above).
The air flow enters through the perforated right side panel of the device, passes through the entire range of internal components, cooling each of them, and is brought out with left perforated panel fans. The remaining panels of the device do not contain ventilation holes, which will allow to maintain the necessary internal pressure of air flow.
Do not block any ventilation openings. This can lead to overheating of the device components and cause its operation disturbances.
If the device is being installed into a closed non-ventilated cabinet with volume less than 180l per device supplied by the DC, device performance will not exceed 0.8 Erlang per subscriber unit.
If the device is being installed into a closed non-ventilated cabinet with volume less than 180l per device supplied by the AC, device performance will not exceed 0.4 Erlang per subscriber unit.

2.8 'F' Function Button Operation
To reboot the operating device, press and hold 'F' button located on the front panel of the device for 1 to 9 seconds. When releasing the button, the Alarm LED will become solid red and the device will reboot. Also, this button allows you to reset the device to factory settings to get access to the device when the IP address or the password is forgotten or is not known. To do this, press and hold the 'F' button for 10-14 seconds until the Status LED begins to flash yellow, green and red alternatively. Then the Alarm LED becomes solid red and the button should be released. The configuration will be reset to factory settings and the device will be rebooted. After that, you can access the device by IP address 192.168.1.2. When connecting with Web configurator, the default password for admin user is rootpasswd. Further, you can view/change IP address and set a new password. If the button is not released during the period between 10 and 14 seconds, after a while all LEDs will go out (the device will start rebooting). Soon after the Status LED will begin to flash yellow, green and red alternatively, and the Alarm LED will begin to flash red. When releasing the 'F' button at this moment, the configuration will not be reset to factory settings and will switch to the Safemode. This mode allows changing the factory configuration, in other words, selecting a method of network settings obtaining - statically or dynamically. If you continue to hold the ‘F’ button in the Safemode, the cycle of the button operation will be repeated, that is, the restart will occur again if the button is held for 1 to 9 seconds, the reset to the factory settings if the button is held for 10 to 14 seconds, etc.
For detailed description of the factory reset procedure, see Section 6.5 Reset the device to the factory
settings.
