SNi50 model

In order to ensure service continuity in an industrial setting, the SNi50 firewall is equipped with two pairs of bypass hardware, which when enabled, enables network traffic to pass through in the event of a power outage or appliance breakdown.

This feature, available from version 4.1 onwards, is disabled by default. If you want to allow bypass to be enabled, high availability must not be configured on the appliance.

The SNi50 multi-function firewall is fanless.

This appliance is equipped with a 48VDC redundant power supply; the 6-pole screw terminal connector provided allows connecting to two independent sources of power.

You can also plug a USB key or an approved USB modem into it. 3 The serial port enables access to the product in console mode; the user can connect to the firewall directly from a computer. The default baud rate on this model is 115200 baud (8N1). 4 Two fiber network ports. 5 Connection of the protective earth circuit. 6 This 6-pole screw terminal connector enables connection to a 48VDC redundant power supply and a P-Fail relay. 7 Four network ports dedicated to Ethernet Bypass (may vary by license).

Redundant power supply and P-Fail (Power Failure) relay

REMINDER
Before plugging any equipment into a DC power supply module, read the security rules carefully and follow them.

Both electrical power supplies can be connected to the SNi50 to provide a redundant power source. Connect the power supplies according to the diagram shown in Connectors and LEDs

A P-Fail relay makes it possible to detect an abnormal status on a power supply. You can connect this relay to a sound or light alarm, such as a buzzer or a LED, equipped with an independent power supply. To do so, connect the external power supply of the alarm to the third and fourth pins. If both power supplies run at the same time, the alarm will be short-circuited. If either power supply is defective, the alarm will go off. The highest intensity that this relay supports is 1A.
