10/100/1000 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 features 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 ve seconds off followed by ten 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: ________________________________________________________________
Before starting, make sure power to the bypass switch is disconnected.
