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 device 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 network 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.
Optical Bypass Switch with Heartbeat
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 trafc 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).

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).
Optical Bypass Switch with Heartbeat
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.

Unpacking and Inspection
Unpack the Optical Bypass Switch, power supplies, and cables provided.
Each Optical Bypass Switch is delivered with the following:
• 2 Power supplies
• 2 LC ber cables (models
HBLX-SC/LC) or 2 LC-to-SC cables (model BPO-HBSX-SC/LC)
BPO-HBSX-LC0, BPO-HB-LX/SX, and BPO-
• 1 DB-9 RS232 cable
• 1 Manual
You may have also purchased a panel for rack mounting the bypass switch and
an extended warranty. If any component is missing or damaged, contact Net
Optics Customer Service immediately.
Conguring the Bypass Switch
The Optical Bypass Switch allows you to set several conguration options and
to display conguration information. You can set:
The frequency of the heartbeat.
This denes the period of time that passes before the switch
considers the packet to have timed out. The default is 1 second.
Optical Bypass Switch with Heartbeat
The number of timeouts allowed.
This is the number of packets missed before the switch bypasses
the IPS (retry count). The default is 3 missed packets.
Port communication parameters.
You can turn Link Fault Detect and Bypass Detect on or off.
The default is LFD and Bypass Detect on.
A custom heartbeat packet.
You can input a custom heartbeat packet to suit special needs. The
default is the IPX packet shown on page 5.
Reset to factory defaults.
Use this option to quickly restore the original conguration.
For quick reference, you can display the conguration settings and heartbeat
packet.

Page 12
Optical 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 fteen 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.
______________________________________________________________________
To access the bypass switch CLI:
1. Using the RS232 DB-9 cable provided, connect a PC running terminal
emulation software, such as HyperTerminal to the RS232 port on the rear
panel of the bypass switch.
2. Set the terminal emulation software to the following communication
parameters:
9600 baud
8 data bit
No parity
1 stop bit
No ow control
3. Connect power to the bypass switch. The software compile date and time
is displayed in the terminal emulation software as shown in the example
below.
