About Network Security Sensors
McAfee Network Security Sensors (Sensors) are high-performance, scalable, and flexible content
processing appliances built for the accurate detection and prevention of:
• network intrusions
• network misuse
• Distributed Denial-of-Service (DDoS) attacks
Sensors are specifically designed to handle traffic at wire speed, efficiently inspect and detect
intrusions with a high degree of accuracy, and flexible enough to adapt to the security needs of any
enterprise environment. When deployed at key network access points, the Sensor provides real-time
traffic monitoring to detect malicious activity and respond to the malicious activity as configured by
the administrator.
After you deploy a Sensor successfully, you configure and manage it using the McAfee® Network
Security Manager (Manager). The process of configuring a Sensor and establishing communication
with the Manager is described in the subsequent chapters of this guide. For the details about the
Manager, see the McAfee Network Security Platform Getting Started Guide.

Overview
Functions of a Sensor
Functions of a Sensor
The primary function of a McAfee® Network Security Sensor (Sensor) is to analyze traffic on selected
network segments and to respond when an attack is detected. The Sensor examines the header and
data portion of every network packet, looking for patterns and behavior in the network traffic that
indicate malicious activity. The Sensor examines packets according to user-configured policies, or rule
sets, which determine what attacks to watch for, and how to respond with countermeasures if an
attack is detected.
If an attack is detected, a Sensor responds according to its configured policy. Sensor can perform
many types of attack responses, including generating alerts and packet logs, resetting TCP
connections, "scrubbing" malicious packets, and even blocking attack packets entirely before they
reach the intended target.
Network topology considerations
Deployment of a Sensor requires knowledge of your network to help determine the level of
configuration and the number of installed Sensors. You also need to determine the number of McAfee
ePolicy Orchestrator (McAfee ePO) /McAfee NAC servers required to protect your network. The Sensor
is purpose-built for the monitoring of traffic across one or more network segments. For more
information, see the McAfee Network Security Platform Getting Started Guide.

1
Power Supply A. Power supply A is included with each Sensor. The supply uses a standard IEC
port (IEC320-C13). McAfee provides a standard, 2m NEMA 5-15P (US) power cable (3 wire).
International customers must procure a country-appropriate power cable.
2
Power Supply B (optional, purchased separately). Power supply B is a hot-swappable, redundant
power supply. This power supply also uses a standard IEC320-C13 port, and you can use
McAfee-provided cable or acquire one that meets your specific needs.
3
One RS-232C Console port, which is used to set up and configure the Sensor.
4
One RS-232C Auxiliary port, which may be used to dial in remotely to set up and configure the
Sensor.
5
Six RJ-11 Fail-Open Control ports, designed for use with the Optical Fail-Open Bypass kit. The
ports are marked X1, X2, X3, X4, X5, X6, (1A-1B to 6A-6B respectively.)
6
Eight small form-factor pluggable (SFP) 1 Gigabit Monitoring ports, which enable you to
monitor eight SPAN ports, four full-duplex tapped segments, four segments in-line, or a
combination (that is, for example, two full-duplex segment and four SPAN ports).
1
7
Four 10 Gigabit small form-factor pluggable (XFP) 10 Gigabit Monitoring ports, which
enable you to monitor four SPAN ports, two full-duplex tapped segments, two segments in-line, or
a combination (that is, for example, one full-duplex segment and two SPAN ports).
The Monitoring interfaces of the M-3050/M-4050 work in stealth mode, meaning they have no IP
address and are not visible on the monitored segment.
If you choose to run in failover mode, port 2A is used to interconnect with a standby Sensor.
The gigabit ports of the M-3050/M-4050 when deployed in in-line, fail-close, meaning that if the
Sensor fails, it will interrupt/block data flow. Fail-open functionality requires either the Layer 2
Passthru feature or the hardware Gigabit Fail-Open Bypass kit for Gigabit ports. The Layer 2
Passthru feature is described in detail in the McAfee Network Security Platform Device
Administration Guide.
8
One External Compact Flash port. This port is used only for flash recovery purposes. That is,
this port is used in troubleshooting situations where the Sensor's internal flash is corrupted and
you need to reboot the Sensor through the external compact flash. For more information, see the
on-line KnowledgeBase at http://mysupport.mcafee.com/Eservice/. Click Search the KnowledgeBase.
9
One RJ-45 Response port, which, when you're operating in SPAN or tap mode, enables you to
inject response packets back through a switch or router.
10
One RJ-45 10/100/1000 Management port, which is used for communication with the
Manager server. You can assign an IP address to this port during installation.
The M-3050/M-4050 does not have internal taps; you must use it with a third-party external tap to
run it in tap mode.
Front and back panel LEDs
The front panel LEDs provide status information for the health of the Sensor and the activity on its
ports. The following table describes the M-3050/M-4050 front panel LEDs.

• This equipment is intended to be grounded. Ensure that the host is connected to earth ground
during normal use.
• Do not remove the outer shell of the Sensor. Doing so will invalidate your warranty.
• Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Blank faceplates and cover panels prevent exposure to hazardous voltages and currents inside the
chassis, contain electromagnetic interference (EMI) that might disrupt other equipment and direct
the flow of cooling air through the chassis.
• To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain
TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting
cables.
• This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy, and if not installed and used in
accordance with the instruction manual, might cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which
case the users will be required to correct the interference at their own expense.
• Refer to the Appendix for information on regulatory, compliance, and other safety requirements.
About fiber-optic ports
The Sensor uses fiber-optic connectors for its Monitoring ports. The connector type is a small
form-factor pluggable (SFP) fiber optic connector that is LC-duplex compatible.
Note the following:
• Fiber-optic ports (for example, SFP/XFP, FDDI, OC-3, OC-12, OC-48, ATM, GBIC, and 100BaseFX)
are considered Class 1 laser or Class 1 LED ports.
• These products have been tested and found to comply with Class 1 limits of IEC 60825-1, IEC
60825-2, EN 60825-1, EN 60825-2, and 21CFR1040.
To avoid exposure to radiation, do not stare into the aperture of a fiber-optic port. Invisible radiation
could be emitted from the aperture of the port when no fiber cable is connected.
• Only FDA registered, EN 60825-1 and IEC 60825-1 certified Class 1 SFP laser transceivers are
acceptable for use with the Sensor.

Setup overview
Setting up a Sensor involves the following steps:
1
Positioning the Sensor.
2
Installing interface modules (SFP and XFP).
3
Attaching power, network, and monitoring cables.
4
Powering on the Sensor.
5
Configuring the Sensor after you have set up and powered it on.
How to position the Sensor
Place the Sensor in a physically secure location, close to the switches or routers it will be monitoring.
Ideally, the Sensor should be located within a standard communications rack. To mount the Sensor on
a rack, you will attach two mounting ears and rails to the Sensor as described in the subsequent
sections of this guide.
Tasks
• Install the rails and ears on the chassis and rack on page 20
McAfee® Network Security Platform M-3050/M-4050 Sensor Product Guide

Setting up the Sensor
How to position the Sensor
Install the rails and ears on the chassis and rack
Before you begin
Before you install the rails and ears on the chassis, make sure that the power is off.
Remove the power cable and all network interface cables from the Sensor.
Each rack-mounting rail and ear has holes that match up with holes in the chassis. You will need a
screwdriver to secure the slotted panhead screws.
Task
1
Verify that you have all the parts you will need — two three-in-one rails, two chassis ears, and
fourteen slotted panhead screws.
Each rail includes a rail that mount to the rack, a rail that slides into the mounted rail, and a rail
that is attached to the chassis.
2
Disassemble the slide rail by pulling the inner rail out and pushing the side latch in to separate.
3
Attach the inner rail to the chassis by fastening it with the screws provided.
4
Attach the ear to each side of the chassis.
5
Mount the L-shape and external rail to your rack frame.
The adjustable end of the L-shape rail is intended for placement at the back of your rack. Adjust
the rail as needed for length. You are now ready to mount the Sensor on the rack.
Mount the Sensor on a rack
McAfee recommends rack-mounting your Sensor. The rack-mounting hardware included with the
Sensor is suitable for most 19-inch equipment racks and telco-type racks. For maintenance purposes,
you must have access to the front and rear of the Sensor.
Before you mount the Sensor on the rack, make sure that the power is off. Remove the power cable and
all network interface cables from the Sensor.
Due to the weight of the appliance, McAfee recommends that two people place the chassis into the rail
cabinet.
Insert the chassis into the rail cabinet and complete the rack-mounting of the Sensor by securing the
rack mount ears to two posts or mounting strips in the rack. The ears secure the Sensor to two rack
posts. Make sure to fasten the ears securely to the rack.
Optionally, you can also mid-mount the Sensor. For details, refer to the corresponding Sensor McAfee
Network Security Platform Quick Start Guide.
Remove a Sensor from the rack
Review this section if you need to remove a Sensor from the rack.

Setting up the Sensor
Redundant power supply
Because of the weight of the appliance, McAfee recommends that two people remove the chassis from
the rail cabinet. When removing the chassis from the rack, pull the chassis forward until you hear the
innermost rails snap in place. On each side of the rails, press in the release button as pictured below
and continue pulling the chassis.
Figure 3-1 Rail release latch

Redundant power supply
A basic configuration of the Sensor includes one hot-swappable supply. You can install a second
hot-swappable power supply for redundancy. You will have to purchase this redundant power supply
separately from McAfee. Each of these modules have one handle for insertion or extraction from the
unit as well as a release latch.
Figure 3-2 Power supply units
Install the power supply
Task
1

faceplate.
Figure 3-3 Installing the power supply
4
Slide in the power supply until it makes contact with the backplane, then push firmly to mate the
connectors solidly with the backplane.
For true redundant operation with the optional redundant power supply, McAfee recommends that
you plug each supply into a different power circuit. For optimal protection, use uninterruptable
power sources.
Remove the power supply
Note that the power supplies are hot-swappable. To avoid data interruption, do not power off both
power supplies on an in-line Sensor, else the Sensor shuts down and all data traffic stops. Power off
only the power supply you are replacing.
Task
1
Unplug the power cable from its power source and remove the power cable from the power supply.
2
Put on an antistatic wrist or ankle strap.
3
Attach the strap to a bare metal surface of the chassis.
4
Push the release latch inward toward the handle.
5
Squeeze the handle of the power supply and pull it out.
6
Use faceplate panels to protect unused slots from dust and reduce electromagnetic radiation.
7
Replace the mounting bracket.
To remove all power from the Sensor, unplug all power cords.
Cable the Sensor
Follow the steps outlined in Attaching Cables to the Sensor to connect cables to the monitoring,
response, console, and management ports on your Sensor.

Small form-factor pluggable modules
The Sensor uses two types of small form-factor pluggable modules as shown in the following table:
Type Performance
SFP 10/100/1000 Mbps (copper)
1 Gbps (fiber optic)
XFP 10 Gbps (fiber optic)
Each module is a hot-swappable input/output device that plugs into an LC-type Gigabit Ethernet port,
linking the module port with a copper or fiber-optic network. SFP optical interfaces are less than half
the size of GBIC interfaces.
To ensure compatibility, McAfee supports only those SFP and XFP modules purchased through McAfee

SFP modules
An SFP module is a hot-swappable, protocol-independant, compact, optical receiver, which allows for
greater port density than the standard GBIC. This module operates at varying speeds for up to 1
gigabit per second on SONET/SDH, Fibre Channel, Gigabit Ethernet and other applications. An SFP
module operates in single mode and multimode. Additionally, this module transmits on a
850-nanometer wavelength on short reach (SR) and 1310-nanometer wavelength on long reach (LR).

About the fail-open port
Fail-open functionality for the GE Monitoring ports is accomplished using the standard Gigabit
Fail-open Bypass Kit, which is sold separately. Both copper and optical versions are available. Fail-open
functionality for the 10 Gigabit Monitoring ports is accomplished using the standard 10 Gigabit
(Optical) Fail-open Bypass Kit, which is also sold separately. For more information, see the
documentation that accompanies the Kit.

Attaching Cables to the Sensor
About the fail-open port
4
To isolate and protect your management traffic, McAfee strongly recommends that you use a
separate, dedicated management subnet to interconnect the Sensors and the Manager.
About connecting cables to the Monitoring ports
Connect to the network devices that you want to monitor through the Sensor monitoring ports. You
can deploy Sensors in the following operating modes:
• In-line mode (fail-close) • SPAN or hub mode
• In-line mode (fail-open) • Failover
• External tap mode
How to use peer ports
All full-duplex Sensor deployment modes require the use of two peer monitoring ports on the Sensor.
On the Sensors, the numbered ports are wired in pairs to accommodate the traffic.
The following XFP 10 Gigabit Ethernet ports and SFP Gigabit Ethernet ports are coupled and must be
used together:
Port Pairs (and Transceiver Type)
1A and 1B (XFP)
2A and 2B (XFP)
3A and 3B (SFP)
4A and 4B (SFP)

Cable types for routers, switches, hubs, and PCs
This section lists the types of cables that you require to connect the Sensor to other network devices:
• Use a crossover Ethernet RJ-45 cable to connect a router port to the 10/100/1000 copper SFP
monitoring ports.
• Use a straight-through Ethernet RJ-45 cable to connect a switch or a hub port to 10/100/1000
copper SFP monitoring ports.
• Use a crossover Ethernet RJ-45 cable to connect a router port to PC to the Sensor Management
port.
• Use a crossover Ethernet RJ-45 cable to connect a PC to the Sensor monitoring port.
Connect the cables for in-line mode
The Gigabit Ethernet ports fail-close, meaning they stop the flow of traffic if the Sensor fails. To allow
traffic to flow uninterrupted, you must use special hardware, and cable the Sensor to fail-open. For
instructions, see the subsequent sections of this chapter.
This section provides the steps to connect the Sensor's Gigabit Ethernet ports so they fail-close.
30
McAfee® Network Security Platform M-3050/M-4050 Sensor Product Guide
Page 31
Task
1
Plug the cable appropriate for use with your Gigabit Ethernet into one of the Monitoring ports, for
example 1A.
2
Plug another cable into the peer of the port used in Step 1.
3
Connect the other end of each cable to the network devices that you want to monitor.
For example, if you plan to monitor traffic between a switch and a router, connect the cable
connected to 1A to the switch and the one connected to 1B to the router.
Connect the cables for tap mode
To deploy the Sensor in tap mode, you must use a Sensor's Gigabit Ethernet Monitoring port pair with
a third-party external tap.
For a list of McAfee-approved third party vendors, see the KnowledgeBase at http://
mysupport.mcafee.com/Eservice/. Click the link Search the KnowledgeBase and locate the relevant
KnowledgeBase article.
Attaching Cables to the Sensor
Connect the cables for tap mode
4
Task
1
Plug the cable appropriate for use with your Gigabit Ethernet into one of the Monitoring ports, for
example, 1A.
2
Plug another cable into the peer of the port used in Step 1.
3
Connect the other end of each cable to the tap.
4
Connect the network devices that you want to monitor to the tap.
Connect the cables for SPAN or hub mode
For the Sensor, monitoring in SPAN or hub mode occurs in in-line fail-open mode. When you monitor in
SPAN or hub mode, you use only single ports.
To connect an Sensor to a SPAN port or hub, plug an LC fiber-optic or 45 cable into one of the modules
and connect the other end of the cable to the SPAN port or the hub.
Cable the fail-over interconnection ports
Fail-over requires connecting two identical M-3050/M-4050 Sensors running on the same software
version using an interconnection cable or cables. Gigabit ports 2A is the interconnection port on the
M-3050/M-4050. A failover cable is the only additional hardware required to support fail-over
communication between two M-3050/M-4050 Sensors.

2
Connect the other end of the cable to port 2A of the standby Sensor.
Figure 4-2 Sensors connected for failover
How does the fail-open function work
The standard Gigabit Fail-Open Kit and the 10 Gigabit Fail-Open Kit minimize the potential risks of
in-line Sensor failure on critical network links. You need to purchase these kits separately. Both copper
and optical versions of the kit are available for the one gigabit ports. A 10 Gigabit Optical Kit is
available for the 10 gigabit ports.
The Monitoring ports of the Sensors fail-close; thus, if the Sensor is deployed in-line, a hardware
failure results in network downtime. For the Monitoring ports to fail-open, you use the optional
external bypass switch provided in a Fail-Open Kit.
With the bypass switch in place, normal Sensor operation supplies power to the switch through a
control cable. While the Sensor is operating, the switch is "on" and routes all traffic directly through
the Sensor. When the Sensor fails, the switch automatically shifts to a bypass state; in-line traffic

Page 33
Attaching Cables to the Sensor
How does the fail-open function work
continues to flow through the network link but is no longer routed through the Sensor. Once the
Sensor resumes normal operation, the switch returns to the "on" state, once again enabling in-line
monitoring.
Sensor outage breaks the link connecting the devices on either side of the Sensor for a brief moment
and requires the renegotiation of the network link between the two peer devices connected to the
Sensor. Depending on the network equipment, this disruption introduced by the renegotiation of the link
layer between the two peer devices might range from a couple of seconds to more than a minute with
certain vendors' devices.
A very brief link disruption might also occur while the links between the Sensor and each of the peer
devices are renegotiated to place the Sensor back in in-line mode. This outage, again, varies depending
on the device, and can range from a few seconds to more than a minute.
You can find the installation and troubleshooting instructions for the kit in the guide that accompanies
the kit. For example, for more information on the Optical kit, see the standard Gigabit Optical
Fail-Open Bypass Kit Guide.
