4 Station Bypass Switch with Heartbeat

Link Fault Detect
You can set the bypass switch to drop the remaining full-duplex link when one

side fails. The Link Fault Detect feature ensures that connected devices are

aware of a failure on both sides of the link.

Bypass Detect
You can set the Monitor Ports to cycle on and off while the bypass switch is

in Bypass Enabled mode. In Bypass Detect mode, the Monitor Ports cycle

through five seconds off followed by fifteen seconds on. The alternating link

status can be used to trigger attached devices to send an alarm to a manage-

ment system every time the bypass switch turns off the Monitor Ports. When

the bypass switch returns to Bypass Disabled mode, the Monitor Ports remain

on and the on/off cycle is discontinued.

Note: ________________________________________________________________

All of the following instructions on pages 7-10 will need to be completed

for each segment of the 4 Station Bypass Switch. Before starting, make sure

power to the bypass switch is disconnected.
