2Site Preparation and Unpacking
This chapter includes the following sections:
●Site Requirements for the Sentriant NG Appliance on page 9
●Unpacking the Sentriant NG Appliance on page 10
Site Requirements for the Sentriant NG Appliance
The Sentriant NG appliance can be rack-mounted in a standard 19-inch rack.
Be sure to locate the system away from heat sources and in an area that provides unobstructed air flow
to the chassis cooling vents. The chassis intake ambient air temperature should not exceed 95 ºF (35 ºC)
or drop below 41ºF (5º C).
CAUTION
Do not place a monitor or other object on top of the system. The mounting brackets and chassis cover are not
designed to support additional weight.
Make sure that the voltage and frequency of the power source matches the electrical ratings of the
Sentriant NG appliance, and that the building and/or power source provides overload protection.
In regions that are susceptible to electrical storms, we recommend that you plug your system into a
surge suppressor.
Rack Ventilation Requirements
●Make sure that there is a minimum of 3 inches of airspace at the back of the chassis.
●Open-type racks should meet the manufacturer’s recommended ventilation requirements.
●Enclosed-type racks should have a louvered front and back with a fan to dissipate heat generated by
equipment mounted in the rack.
●If you are installing the Sentriant NG appliance in enclosed racks with top-mounted ventilation fans,
make sure that there is adequate ventilation for the racks. Heat generated by equipment mounted in
the bottom of the rack can be drawn up into equipment mounted in the top of the rack.
●Chassis intake ambient air temperature should not exceed 95º F (35º C).
●Operating humidity should be kept between 10% and 95% relative humidity (noncondensing).

Site Preparation and Unpacking

Overview
The Sentriant NG appliance fits into a standard 19-inch (48.26 cm) rack.
Carefully read all cautions and warnings before beginning the installation.
CAUTION
The Sentriant weighs approximately 40 pounds (18 kilograms). To reduce the risk of personal injury, do not attempt
to install the system in a rack by yourself.
CAUTION
The Sentriant rack installation procedures should be performed by trained service technicians.
CAUTION
Do not place a monitor or other object on top of the Sentriant chassis. The chassis bracket hardware is not designed
to support the additional weight of objects other than the Sentriant chassis.
WARNING!
If you are installing more than one Sentriant in a rack, always install the first Sentriant in the lowest available
position in the rack. Installing a Sentriant in a high position in the rack first could cause the rack to tip over.

Connecting Cables
Connect cables to the Sentriant NG appliance as follows:
●Serial port connection
Connect the provided serial cable from the serial port on the of the Sentriant NG appliance to a
DB-9 serial port on a workstation.
●Management port
Connect a Category 5 or equivalent UTP cable from the management port on the Sentriant NG

Connect two category 5 or equivalent UTP cables from detection/mitigation ports 1 and 2 on the
Sentriant NG appliance to two open 10/100/1000BASE-T I/O ports on an Extreme Networks switch.
NOTE
Only one detection/mitigation port is needed for a default configuration. Use the additional detection/mitigation ports
if more than one VLAN is configured.
Configuring the Switch
Configure the switch as follows:
1Configure the switch port connected to detection/mitigation port 1 to be a mirror port.
2Configure the switch port connected to detection/mitigation port 2 to be a member of the VLAN
that will be monitored for threats. This VLAN should be 802.1q tagged.
3Configure the switch to mirror the threat detection VLAN.

4Start-Up and Initial Configuration
This chapter includes the following sections:
●Requirements Before the Initial Setup on page 17
●Initial Configuration Using the Serial Port on page 17
●Installing the Sentriant NG Manager Software on page 23.
Requirements Before the Initial Setup
You must configure a read-only port and a VLAN read-write port on the Extreme Networks switch
before performing the initial setup of the Sentriant NG appliance. The read-write port must be mirrored
to the read-only port. The VLAN read-write port must be tagged to all VLANs being protected by the
Sentriant NG appliance.
To configure these ports, use the following CLI commands:
enable mirroring to port <ReadOnly_port> tagged
configure mirroring add port <ReadWrite_port>
configure vlan <vlan> add ports <ReadWrite_port> tagged
On BlackDiamond 8800 series switches and Summit X450a series switches, the CLEAR-Flow policy file
must be configured for all VLANs protected by the Sentriant NG appliance.
To configure the CLEARflow policy file, use the following CLI commands:
configure access-list <policy_file> vlan <vlan_name>
enable clear-flow
Initial Configuration Using the Serial Port
You must perform the initial configuration of the Sentriant NG appliance using the serial port
connection on the front of the appliance. After initial configuration, you can manage the system
remotely using the Sentriant Console Manager.
You can use any standard VT100
style terminal program such as Microsoft Windows HyperTerminal to
establish communications. When the connection to the Sentriant NG appliance is established, the
Sentriant text user interface guides you through the initial configuration procedure.
Configure the VT100 terminal program with the following settings:
●Baud rate = 38.4 Kbps
●Data bits = 8
●Parity = none
●Stop bits = 1
●Flow control = none
Follow the instructions in “Power-On and System Boot” on page 18 to establish a local connection.
