1Introduction

StreamGroomer SG4410 series have been designed and optimized to leverage the Streamcore Suite of network

performance management applications to ensure good user experience of your business applications at medium-sized

sites.

As part of the SG4410 series, the StreamGroomer SG4412 appliance monitors, controls and accelerates application flows

across the WAN. Deep Packet Inspection (DPI) and a library of well-known application protocols classify application flows for

measurement, control and WAN optimization.

This document is intended to describe the possible deployment cases of the StreamGroomer SG4412 and supported

network architectures.

This document also describes the initial configuration steps to register the appliance to the SGM and a list of elements to

check in case of connectivity issues.

It is recommended to read this document before proceeding with the installation of the SG4412.

It is highly recommended to refer to the following Streamcore documentation:

•StreamView User Guide: for Site and StreamGroomer provisioning and configuration,

•SGM User Guide (SGMConf): for securing the communication between the SGM and the StreamGroomer

2Preparing the deployment of the SG4412

Installing the appliance inline on the network consists in a list of simple tasks. A preparation phase is required for a

successful deployment.

2.1 TASK 1 - UNPACK THE SG4412

The appliance is delivered in a carton box. The serial number of the appliance is available on the bottom of the box.

2.2 TASK 2 – GATHER INFORMATION AND RESOURCES

A computer running a terminal emulator and a USB storage device will be used to setup the StreamGroomer. You may need

a DB9 to USB converter cable as well.

Before deploying the appliance, a preparation task consists in gathering the following information:

IP address, mask and gateway of the SGM. The gateway is required if the SGM and the SG are not located in the same

subnetwork.

If a backup SGM exists, the IP address of the backup SGM is also required.

IP address, mask of the SG4412 also called Administrative IP address. If two SG4412 are deployed in Dual or Tandem

mode, an IP address and mask must be assigned to each SG.

DNS server IP address (used for manual requests from the boot menu such as ping…)

Number of WAN links to monitor

Method to insert the SG4412 in the network: as a single appliance, in DUAL mode or in Tandem mode.

Security level of the communication between the StreamGroomer and the SGM: RSH, weak configuration or strong

configuration. Check the SGM configuration (passphrase).

Line mode of administration port (speed, duplex).

Method to set the configuration of the SG: with a USB stick or with the command line

2.3 TASK 3 – CONFIGURE THE APPLIANCE

Streamcore.com Page 5 on 26

Then the appliance can be configured with the console cable connected to a PC. It is also possible to configure the SG with

a file generated by the SGM.

Refer to chapter Configuring Boot Parameters for the details to configure the appliance.

2.4 TASK 3 – CHECK THE CONNECTIVITY

Refer to chapter Check Connectivity for this activity.

3Description of the SG4412

3.1 UNPACKING THE SG4412

The SG4412 carton contains the appliance and some accessories:

•1 StreamGroomer SG4412

•1 power supply cord and the power supply adapter

•1 RJ45 console cable

•3 gray straight cables

•2 red crossover cables

•Rackmount ears

3.2 FRONT PANEL FEATURES

The front panel contains all the interfaces of the SG4412 described here from left to right:

•Status LEDs:

Status of the appliance

Power If the LED is on it indicates that the system is powered on.

If it is off, it indicates that the system is powered off.

Status If the LED is green, it indicates that the system’s operational state is normal.

If it is red, it indicates that the system is malfunctioning.

HDD If the LED blinks, it indicates data access activities; otherwise, it remains off.

•A LCD screen indicating that the model is StreamGroomer SG4412. The push buttons are not operational.

•A Reset button can be used to reboot the StreamGroomer without turning off the power. (software reboot)

•Interfaces for configuration:

Console and USB

Console

By using suitable rollover cable or RJ-45 to DB-9 console cable, you can

connect to a computer terminal for diagnostic or configuration purpose.

Terminal Configuration Parameters: 115200 baud, 8 data bits, no parity, 1

stop bit, no flow control.

USB The USB 2.0 ports are used to allow the SG to retrieve a configuration file

from a storage device. The configuration file is generated with the SGM.

•Interfaces for monitored WAN access links

WAN access links

LAN1

WAN1 LAN1 and WAN1 are associated with a LAN bypass.

LAN2

WAN2 LAN2 and WAN2 are associated with a LAN bypass.

•Interfaces for management

Management ports

ADMIN

This interface is a GigaEthernet port. The ADMIN interface is used as port

to manage the SG4412 with the SGM.

An IP address will be assigned to this interface for that purpose.

EXT

This interface is a GigaEthernet port. The EXT interface is used to connect

a second SG4412 to the appliance in order build the DUAL and TANDEM

configurations.

The following table describes the meaning of the colours for the Ethernet ports:

Ethernet ports

SPEED

Amber The connection speed is 1000Mbps.

Green The connection speed is 100Mbps.

Off The connection speed is 10Mbps.

LINK/ACT

On/Flashing The port is linking and active in data transmission.

Off The port is not linking.

3.3 REAR PANEL

The figure below represents the rear panel of the SG4412.

From left to right, the rear side is composed of:

•A tray for additional storage 2’5 SSD or HDD. Additional storage is reserved for future implementations.

•A fan to control the temperature of the CPU of the StreamGroomer

•A Power On/Off switch to turn on or off the appliance

•The power supply connector: the system uses AC 150W power supply.

4Configuring Boot Parameters

4.1

4.2 OVERVIEW

To configure the StreamGroomer, a computer equipped with a serial DB9 connector or USB connectors is recommended.

If the computer has no serial connector, it is possible to use a USB to DB9 serial adapter cable that will be connected to the

USB port of the computer on one side and on the other side to the console cable provided with the StreamGroomer. In this

case, it can be necessary to install the specific software to use the z on the computer.

There are two methods to configure the boot IP parameters of a StreamGroomer:

•With a computer connected to the StreamGroomer with the asynchronous cable on the console port (and optionally

the DB9 to USB converter): access to the boot menu of the SG

•With a USB key: reboot the SG on a USB key containing a configuration file prepared with the StreamView application.

This method does not require a computer to configure the StreamGroomer.

Both methods are explained hereafter.

4.3 CONFIGURE STREAMGROOMER BOOT PARAMETERS WITH THE CONSOLE

4.3.1 Connect the computer to the SG4412

You have to connect a computer to on the console port of the StreamGroomer with the DB9 asynchronous cable (and the

additional DB9 to USB adapter cable). The asynchronous cable is provided with the SG4412. The asynchronous cable has a

RJ45 connector and a DB9 connector.

4.3.2 Configure the connection

To access the BOOT menu, you have to connect to the StreamGroomer through the asynchronous port via a DB9

asynchronous cable. The most well-known utilities are HyperTerminal, PuTTY or Teraterm for Windows. The configuration

has to be done manually by entering the asynchronous port settings as follows:

•Speed 115200 bit/s,

•Parity: NO,

•Flow control: NO

•1 stop bit,

•8 bits of data.

Press Enter key. The following screen appears:

Figure 3 - Initial login as boot user

Log on with the user boot and the password boot.

Once entered in the boot menu, two modes are available:

Maintenance mode: This is the default mode. Type help to display the list of commands available in this menu.

Configuration mode. To enter the configuration mode, type the keyword configure (config is also recognized).

You can exit any menu with the exit command. Command completion is possible with the TAB key.
