All fail-open switches are provided with four basic ports. Two of these connect to monitoring ports of the Sensor and while the other two connect to network devices that route traffic to the network.
Active fail-open switches have two power ports for a primary and a secondary power source. They also have LEDs that show bypass status. Certain models also have LEDs to show utilization threshold status for each port.
There are several types of fail-open switches that enable you to choose the one that best suits your requirements. When you make your choice of fail-open kit, be sure to consider the following factors:
How quickly you need traffic to bypass the Sensor during an outage – Depending on how quickly you require traffic to bypass a Sensor during an outage, you can decide between an active or a passive fail-open switch and a copper or a fiber fail-open switch. For more details about the differences between the speed of active switching and passive switching, refer to the following sections:
Distance between the fail-open switch and Sensor – All fail-open switches have an upper limit that is set by the type of cable used for data transport.
Cost – Finding the right balance between cost and your requirements is another factor in determining the ideal fit for a fail-open switch.
