4 Station Bypass Switch with Heartbeat
Introduction
Thank you for choosing the most versatile Bypass Switch available today.
Whether you are a novice or an expert, this installation guide is designed to
help answer any questions and provide a quick set-up reference.
Net Optics 4 Station Bypass Switches with Heartbeat provide a permanent and
trouble-free access port for up to four in-line network security and monitor-
ing segments. These Bypass Switches automatically switch network traffic
through added in-line devices or bypass devices that are about to be removed .
With the heartbeat technology, the 4 Station Bypass Switch protects up to four
network traffic links independently against signal loss, power loss and applica-
tion failure to the attached in-line devices.
Link Fault Protection
The 4 Station Bypass Switch with Heartbeat monitors the attached in-line
device by sending a heartbeat packet to the device. If each Bypass Switch
does not receive the heartbeat back, it automatically switches network traffic
to bypass the unresponsive device—even if the device is still receiving power.
Each Bypass continues to send the heartbeat and restores the traffic through
the in-line device as soon as the link is restored .
Uninterrupted Traffic
The 4 Station Bypass Switch supports fail-open monitoring with any in-line
device when it shares the same power source as the in-line appliance. For
as long as the Bypass Switch is receiving power, it diverts network traffic to
attached in-line devices. In this state, all in-line traffic is routed directly to the
devices connected to the 4 Station Bypass Switch segment.
When the 4 Station Bypass Switch loses power, in-line traffic continues to
flow through the network links, but is no longer routed through the devices.
This allows the in-line devices to be removed and replaced without network
downtime. Once power is restored to the Bypass Switch, network traffic is
seamlessly diverted to the in-line devices, allowing it to resume their critical
functions.
Three Simple Steps
Three quick steps is all it takes to establish a secure connection point for
inline devices . For special applications, customize the bypass trigger and
Heartbeat rate from an RS232 command line interface.
