Optical Bypass Switch with Heartbeat
Introduction
Thank you for choosing the most versatile Optical Bypass Switch available
today. Whether you are a novice or an expert, this installation guide is
designed to help answer any questions and to provide a quick set-up reference.
Net Optics Optical Bypass Switches with Heartbeat provide a permanent and
trouble-free access port for in-line network security and monitoring devices.
The Optical Bypass Switch automatically switches network trafc through
added in-line devices or bypasses devices that are about to be removed. With
a heartbeat, the Optical Bypass Switch protects network trafc against both
signal and power loss on the attached in-line device.
Link Fault Protection
The Optical Bypass Switch with Heartbeat monitors the attached in-line de-
vice by sending a heartbeat packet to the device. If the Optical Bypass Switch
does not receive the heartbeat back, it automatically switches network trafc
to bypass the unresponsive device—even if the device is still receiving power.
The Optical Bypass continues to send the heartbeat and restores the trafc
through the in-line device as soon as the link is restored.
Uninterrupted Trafc
The Optical Bypass Switch supports fail-open monitoring with any GigaBit
in-line device when it shares the same power source as the in-line appliance.
For as long as the Optical Bypass Switch is receiving power, it diverts net-
work trafc to attached in-line devices. In this state, all in-line trafc is routed
directly to the device connected to the Optical Bypass Switch.
When the Optical Bypass Switch loses power, in-line trafc continues to
ow through the network link, but is no longer routed through the device.
This allows the network devices to be removed and replaced without network
downtime. Once power is restored to the Optical Bypass Switch, network traf-
c is seamlessly diverted to the in-line device, allowing it to resume its critical
functions.
Simply Plug It In
Each Bypass Switch includes all the cables and power supplies you need
to quickly connect to an IPS. 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.

Bypass Modes
The Optical Bypass Switch with Heartbeat bypasses attached in-line device
when one of three events occurs:
• Power loss to the switch
• Link failure
• Application failure
Two LEDs on the front of the Optical Bypass Switch indicate whether the
switch is bypassing the connected appliance or not. When the Bypass ON
indicator is illuminated, the bypass switch has not received the heartbeat
packet as expected and is in Bypass Enabled mode. When the Bypass OFF
indicator is illuminated, the bypass switch is in Bypass Disabled mode and is
sending trafc through the attached in-line device.
When the switch is in Bypass Enabled (ON) mode, the switch circuitry
re-directs network trafc around the in-line appliance. In Bypass Enabled
mode Network Ports A and B are connected (see Figure 4).
Figure 4: Bypass Enabled
When the switch is in Bypass Disabled (OFF) mode, the switch circuitry
sends network trafc through the in-line appliance. In Bypass Disabled mode,
Network Port A is connected to Monitor Port C and Network Port B is con-
nected to Monitor Port D (see Figure 5).

Optical Bypass Switch with Heartbeat
Power Loss Bypass
The Optical Bypass Switch protects link integrity when the attached in-line
device loses power. To install the Optical Bypass Switch for this type of
protection, the switch should share the same power source as the in-line
appliance. If you are using redundant power supplies for the switch, make
sure that both are connected to the same power source as the in-line device.
Heartbeat Bypass
The Optical Bypass Switch with Heartbeat protects against both physical link
failure and application failure on the in-line appliance. The switch checks
the path through the in-line appliance by sending a packet every second from
Monitor Port C. The switch validates the path when it receives the packet
on the Monitor Port D. If the switch does not receive the packet as expected
three times in a row, the switch automatically enters Bypass Enabled (ON)
mode.You can change the number of the heartbeat packets required before the
bypass switch enters Bypass Enabled mode from the bypass switch CLI (see
Conguring the Bypass Switch on page 6).
Below is the default IPX heartbeat packet sent once every second from the
Monitor Port C. You can change the default timing of the heartbeat packet
and the heartbeat packet from the bypass switch CLI (see Conguring the
Bypass Switch on page 6).
The switch continues to send the bypass packet and will return to Bypass
Disabled mode when it receives three consecutive packets on Monitor Port D.
The default IPX and IP packets are shown on the following page. Units are
shipped from the factory with the IPX packet. When the factory defaults are
restored using the "z" CLI command (see "To restore the bypass switch to
factory defaults" on page 11), you will be able to select either the IPX or IP
packet.
