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 traffic through added in-line devices or bypasses devices that are about to be removed . With a heartbeat, the Optical Bypass Switch protects network traffic 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 traffic to bypass the unresponsive device—even if the device is still receiving power.
The Optical 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 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 traffic to attached in-line devices. In this state, all in-line traffic is routed directly to the device connected to the Optical Bypass Switch.
When the Optical Bypass Switch loses power, in-line traffic continues to flow 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 traffic 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 traffic through the attached in-line device.
When the switch is in Bypass Enabled (ON) mode, the switch circuitry re-directs network traffic around the in-line appliance. In Bypass Enabled mode Network Ports A and B are connected (see Figure 4).

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
Configuring 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 Configuring 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 .

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 fiber cables (models
BPO-HBSX-LC
0,
BPO-HB-LX/SX
, and
BPO-
HBLX-SC/LC
) or 2 LC-to-SC cables (model
BPO-HBSX-SC/LC
)
• 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.
Configuring the Bypass Switch
The Optical Bypass Switch allows you to set several configuration options and to display configuration information. You can set:
The frequency of the heartbeat.
This defines the period of time that passes before the switch considers the packet to have timed out. The default is 1 second.
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 configuration.
For quick reference, you can display the configuration settings and heartbeat packet .
7
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 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 management 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 flow 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 .
