10/100/1000 Bypass Switch with Heartbeat
Introduction
Net Optics 10/100/1000 Bypass Switches with HeartbeatTM provide perma-
nent and trouble-free access ports for in-line network security and monitoring
devices. The Bypass Switch automatically switches network trafc through
added in-line devices or bypasses devices that are about to be removed. With
a heartbeat, the 10/100/1000 Bypass Switch protects network trafc against
link, application, and power loss on the attached in-line device.
Link Fault Protection
The 10/100/1000 Bypass Switch with Heartbeat monitors the link to the
attached in-line device by sending a heartbeat packet to the device once every
second. If the Bypass Switch does not receive the heartbeat back, Fast PathTM
switching automatically diverts network trafc to bypass the unresponsive
device—even if the device is still receiving power. The Bypass Switch contin-
ues to send the heartbeat and restores the trafc through the in-line device as
soon as the link is restored.
Uninterrupted Trafc
The 10/100/1000 Bypass Switch supports fail-safe monitoring with any
10/100/1000BaseT in-line device when it shares the same power source as
the in-line appliance. While the 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 Bypass Switch.
When the 10/100/1000 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 Bypass Switch, network trafc is
seamlessly diverted to the in-line device, allowing it to resume its critical
functions.
Link Fault DetectTM
For superior reliability, the Bypass Switch features Link Fault Detect which
gives the devices connected to the Tap critical information about link status. If
either side of the bi-directional link fails, the Tap immediately communicates
the fault to both devices, reducing the time required to activate a redundant
path.

LED Indicators
PWR 1/ PWR 2: Main and Redundant Power. If the Bypass switch is
deployed with both power supplies, both LEDs illuminate green when
power is connected to the bypass switch. An off power LED indicates that
the corresponding power supply is not functioning or not connected.
10/100/1000 Indicator: Located in the upper left-hand corner of the RJ45
connectors. If the Port is set to 10 Mbps, the LED illuminates orange. If
the Port is set to 100 Mbps, the LED illuminates yellow. If the Port is set to
1000 Mbps, the LED
illuminates green.
Link/Activity Indicator: Located in the upper right-hand corner of the
RJ45 connectors. If a good link is established, the LED illuminates a steady
green. When there is current activity on a good link, then the LED ashes.

10/100/1000 Bypass Switch with Heartbeat
Bypass Modes
The 10/100/1000 Bypass Switch with Heartbeat bypasses the 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 10/100/1000 Bypass Switch indicate whether
the bypass 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. When the Bypass OFF indicator is illuminated,
the bypass switch is sending trafc through the attached in-line device.
When the bypass 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 3).
Figure 3: Bypass Enabled
When the bypass switch is in Bypass Disabled (OFF) mode, the bypass switch
circuitry sends network trafc through the in-line appliance. In Bypass Dis-
abled mode, Network Port A is connected to Monitor Port C and Network Port
B is connected to Monitor Port D (see Figure 4).

10/100/1000 Bypass Switch with Heartbeat
Power Loss Bypass
The 10/100/1000 Bypass Switch protects link integrity when the attached
in-line device loses power. To install the 10/100/1000 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 10/100/1000 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 (default setting), the switch automatically enter Bypass Enabled
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 heartbeat packet sent once every second from the Moni-
tor 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).

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 10/100/1000 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.
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 set the ports for xed speed or auto-negotiation and full- or
half-duplex communications. You also 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.
