1.1 Important safety notes
• This product should be installed, operated, and serviced as specified in this and
other product documentation. A failure to adhere to published directives may result
in equipment damage and/or personal injury. Spirent assumes no liability for
damage or injury that occurs as a result of a failure to heed the documentation, and
likewise any damage caused in this manner may void the warranty. Additionally:
– Installation, operation, and service should be performed by qualified personnel
with a strong knowledge of the product and local safety procedures.
– The unit is intended for use in areas with restricted access only.
– The cover of the unit should not be removed, nor should the unit be
disassembled in any manner not explicitly described in this document.
– Fuses and wiring should be rated as specified in this document. Fuses should
never be bypassed.
– While energized, metal objects and body parts should be kept clear of the
power terminals.
• Read the installation instructions before connecting the system to the power
source.
• To prevent the system from overheating, do not operate it in an area that exceeds
the maximum recommended ambient temperature of 104°F (40°C).

1-2 Introduction www.spirent.com
• Installation of the equipment must comply with local and national electrical codes.
Additionally, equipment with isolated ground (earthing) receptacles are required to
comply with NEC 250.146(D) and CEC 10-112 and 10-906(8).
• Do not stack the chassis on any other equipment. If the chassis falls, it can cause
severe bodily injury and equipment damage.
• To prevent personal injury or damage to the chassis, never attempt to lift or tilt the
chassis using the handles on modules (such as power supplies, fans, or cards);
these types of handles are not designed to support the weight of the unit.
• This equipment must be grounded. Never defeat the ground conductor or operate
the equipment in the absence of a suitably installed ground conductor. Contact the
appropriate electrical inspection authority or an electrician if you are uncertain that
suitable grounding is available.
• When installing or replacing the unit, the ground connection must always be made
first and disconnected last.
• If the unit has more than one power connection, all connections must be removed
to de-energize the unit.
• The plug-socket combination must be accessible at all times, because it serves as
the main disconnecting device.
• This product requires short-circuit (overcurrent) protection, to be provided as part of
the building installation. Install only in accordance with national and local wiring
regulations.
• No user-serviceable parts inside. Do not open unit.
• Any power cords provided by Spirent are intended for use with Spirent products
only.
• Ultimate disposal of this product should be handled according to all national laws
and regulations.
• For AC-powered units, the product must be connected to an external special
protection device (SPD) when installed and connected to commercial AC power,
such as a circuit breaker installed in the service panel.

100 Gbps test ports.The total simultaneous bandwidth across both ports is 200 Gbps,
with some limitations.
Note that this document does not contain comprehensive details on TL1-based
operation of the unit; for more information on TL1 commands, see the TL1 Command
and Operation Manual.
1.2.2 Intended audience
This document is intended for:
•Field technicians - Responsible for the installation and provisioning of the
equipment
•Systems designers and engineers - Responsible for system design and
architecture
To understand and complete all the procedures in this document, you should have a
working knowledge of Ethernet, TL1 usage, and networking equipment in general.

2.2 Product purpose and architecture notes
The VisionWorks Probe is an Ethernet-based network probe that provides customer-
focused testing functions for Ethernet and IP layer protocols. It includes basic test
features such as ping and traceroute to more advanced testing of network performance
for characteristics such as IP jitter, latency, and loss. It is particularly well-suited for
emulating customer usage to verify SLA traffic conformance after link turnup and during
customer use.
The unit is typically installed in a CO or other location where an appropriate Ethernet
transport device is available for service access. In most cases, the unit interfaces with
an Ethernet switch or similar NE at some strategic test point and is managed remotely
by an operational support system (OSS). The following figure shows a common
architecture for testing from “edge” devices of a carrier-class Ethernet service, perhaps
a VLAN-based LAN service or a layer 2 VPN (L2VPN):
The installation and handling of this product carries the risk of electrical
shock.
This product falls under Waste Electronic and Electrical Equipment (WEEE)
Directive. Before disposing of this product, consult local regulations and/or

2.2.1 Typical unit configuration (wiring/connectivity)
The following diagram shows a typical physical configuration of the unit with an access
device, in this case an Ethernet switch. The unit supports “RTU mode” access only,
which requires configuration by an external operator or system to provide the desired
test signal to the unit and/or access to the network:

NOTE: As an option, the unit supports in-band management, in which
case the Ethernet/IP mgmt port connection is not applicable. For
more information, see About in-band management on page 4-8.
2.2.2 Access device notes
The unit test port(s) are designed to interface with an Ethernet-based NE access
device such as a switch, hub, or router. Specific details on interoperability are complex
and beyond the scope of this document. For more information, please contact Spirent.
A network administrator typically selects the port(s) for test access and performs any
necessary configuration, then informs the installation personnel so they know where to
connect the unit test interface(s). In an OSS-controlled architecture, the OSS may
perform access device configuration automatically upon access requests, allowing a
more flexible and dynamic architecture.
Further discussion on external systems and access strategies is beyond the scope of
this document. For more information, contact a network administrator or your Spirent
account representative.
