Introduction
Thank you for choosing Net Optics 10 GigaBit Fiber, GigaBit Fiber, or 10/100/1000
iBypass Switch, the most versatile intelligent iBypass Switches available today. This
guide is designed to help answer your questions and provide an installation reference.
Net Optics iBypass Switch with Heartbeat provides a permanent access port for in-
line network security and monitoring. The iBypass Switch automatically switches
network trafc through added devices, or bypasses devices that are removed. The
intelligent iBypass Switch Heartbeat provides notications to protect network
trafc against both signal and power loss on an attached device.
About this Guide
This guide describes the installation and use of the following models:

Features
Heartbeat Packet
The iBypass Switch monitors the attached device by sending a Heartbeat packet
to the device. If the iBypass Switch does not receive the Heartbeat response, it
automatically switches network trafc to bypass the unresponsive device—even
if the device is still receiving power. The iBypass continues to send the Heartbeat,
and will restore trafc ow through the device as soon as the link is restored .For
special applications, you can customize the Heartbeat Packet rate from the iBypass
Command Line Interface (CLI) or Web Manager GUI.

Uninterrupted Trafc
This iBypass Switch supports fail-open monitoring with any 10 GigaBit device
when it shares the same power source as the device. As long as the iBypass Switch
is receiving power, it will divert network trafc to attached monitoring devices.
In this state, all trafc is routed directly to the monitoring device connected to the
iBypass Switch.
When the iBypass Switch loses power, trafc continues to ow through the
network link, but is no longer routed through the iBypass Switch. This allows
network devices to be removed and replaced without network downtime. Once
power is restored to the iBypass Switch, network trafc is seamlessly diverted to
the monitoring device, allowing it to resume its critical functions.
Simply Plug It In
10 GigaBit iBypass Switches use XFP transceivers and GigaBit iBypass Switches
use SFP transceivers. The port kit includes the cables you need to establish a
secure network connection point for inline devices, and the cable to connect
monitoring devices.
Bypass Detect
You can set the Monitor Ports to cycle on and off while the iBypass Switch is in
Bypass ON mode in order to trigger attached devices to alarms to a management
system. In Bypass Detect mode, the monitor ports will cycle through ve seconds
off followed by fteen seconds on. When the iBypass Switch returns to Bypass
OFF mode, the monitor ports remain on and the on/off cycle is discontinued.
Link Fault Detect
You can set the iBypass Switch to drop the remaining network link when one
side of the link fails. The Link Fault Detect (LFD) feature ensures that connected
devices are aware of a failure on both sides of the link.
Note ____________________________________________________________________
Net Optics warrants the operation of the iBypass Switches only with XFP and SFP
modules supplied by Net Optics.

Bypass Modes
The iBypass Switch with Heartbeat bypasses attached in-line device and sends
trafc straight through the network link when one of three events occurs:
• Power loss to the switch
• Link failure
• Application failure

Two LEDs on the front of the iBypass Switch indicate whether the switch is
bypassing the connected appliance or not. When the Bypass ON indicator is
illuminated, the iBypass Switch has not received the heartbeat packet as expected
and directly connects Network Ports A and B.

Power Loss Bypass
The iBypass Switch protects link integrity when the attached monitoring device
loses power. To install the iBypass Switch for this type of protection, the switch
should share the same power source as the monitoring appliance. If you are using
redundant power supplies for the iBypass Switch, make sure that both monitoring
devices are connected to the same power source as the iBypass Switch device.
Heartbeat Bypass
The iBypass Switch with Heartbeat protects against both physical link failure
and application failure on the monitoring device. The iBypass Switch checks the
path through the monitoring device by sending a packet at a predetermined rate
(for example, once every millisecond from Monitor Port 1). The iBypass Switch
validates the path when it receives the packet on the Monitor Port 2. If the iBypass
Switch does not receive the packet as expected three times in a row (assuming the
Retry count is set to 3), the iBypass Switch automatically enters Bypass ON mode.
You can use the CLI or remote interfaces to change the number of the Heartbeat
packets required (Retry parameter 1-255) before the iBypass Switch enters Bypass
ON mode. The switch continues to send the bypass packet and will return to Bypass
OFF mode the rst time it receives a heartbeat packet on Monitor Port 2. The
contents of the default Heartbeat packet can be seen on page 41.
Manual Bypass
The iBypass Switch can be manually set to Bypass ON mode by setting the Heartbeat
Timeout parameter to 0 using the CLI or remote interfaces. It returns to normal
operation when the Timeout parameter is restored to a non-zero value. No Heartbeat
packets are transmitted when the iBypass Switch is in Manual Bypass mode.
Tap Mode During Bypass
Whenever the iBypass Switch is in Bypass ON mode, it operates as a full-duplex
breakout Tap, copying the trafc received at Network Port A to Monitor Port 1,
and trafc received at Network Port B to Monitor Port 2. This function enables the
attached device to monitor network trafc out-of-band, for instance to baseline the
system prior to putting the device in-line. The only difference from a normal network
Tap is that Heartbeat packets continue to be transmitted (if the Switch is not in Manual
Bypass mode) in order to detect when the monitoring tool comes back online.
Note:____________________________________________________________________
When using the iBypass Switch as a network Tap, be sure to set the Bypass Detect
Feature to "OFF" so the ports remain on constantly.
__________________________________________________________________________

SNMP Traps
The iBypass Switch transmits SNMP traps for the following events:
• Bypass state changes
• Utilization exceeds the threshold on any port
• Any port link status changes
• Port manually disabled
• Either power supply state changes
Trafc Statistics
The iBypass Switch collects statistics about the trafc passing through each of
its ports. The statistics can be viewed and cleared using any of the management
interfaces.
The trafc statistics collected by the iBypass Switch on each of its ports are:
• Peak trafc rate
• Time of the peak trafc
• Current bandwidth utilization
• Total number of packets
• Total number of bytes
• Number of Cyclical Redundancy Check (CRC) errors
• Number of oversize packets
Note _________________________________________________________________
The trafc statistics counters are 32 bits wide, so the maximum value of each
counter is 4,294,967,295. The counters roll over to 0 after the maximum count
is reached. Be aware that, at 10 Gbps, the Total Bytes counter can roll over in
as short a time as 3.4 seconds and the Total Packets counter in 3.7 minutes.

If data is not displaying as expected, check the Network Port connectors for link
status and activity. Also check the status of the display command using the CLI
(see Using the Command Line Interface in chapter 2).
Threshold Alarm LEDs
Four LEDs indicate that utilization levels have exceeded the threshold. There is one
LED per port for incoming trafc on the front panel. When a Threshold Alarm LED is
red, it indicates that the threshold level was exceeded for that port since the last reset.
The LEDs remain illuminated until reset via the reset button or remote interfaces.
(Threshold alarm LEDs are not provided on the 10/100/1000 iBypass Switch.)
Link LEDs
Four LEDs indicate link status. If a good link is established, the LED illuminates a
steady green. If there is no current activity on this link, the LED ashes.
Power LEDs
If the iBypass Switch is deployed with both power supplies, both power LEDs
will illuminate when connected to power. If a power LED is off, the corresponding
power supply is not functioning or connected.
Reset Button
Press the Reset button to reset the trafc peak and time on the display and the
Threshold Alarm LEDs. To prevent accidental resets, the Reset button is recessed
from the front panel. To push the Reset button, use a thin, rigid tool such as an
unbent paperclip.

2. Slide the iBypass Switch into one of the slots and secure the device by
tightening the thumb screws.
3. Make sure that the rack is properly grounded.
Connect Power to the iBypass Switch
For power fault protection, the iBypass Switch has redundant power supplies. The
second power supply is available to support the ow of trafc to the monitoring
device in the event that the rst power supply becomes unavailable. If the rst
power supply is unavailable, the second power supply provides all power for the
iBypass Switch. Even if no power is available to the passive iBypass Switch,
network trafc ows uninterrupted.
