6Quick Start

System Basics

System requirements vary depending how you use the application and the operational environment.

Because we do not know your specific network and devices, the recommendations are based on

typical, not definitive figures, and are as much suggestions as requirements.

Base the minimum configuration of any system on its expected peak load. Your installation should

spend 95% of its time idle and 5% of its time trying to keep pace with the resource demands.

Supported Operating System Versions

Disable firewall products during initial installation and testing. The following are recommended

operating system versions: The following are supported operating system versions:

Microsoft Windows

—This application supports most Windows operating systems from Windows

XP forward, with their latest service packs. The supported operating systems are: Windows 2003

(Standard, Enterprise and Web), Windows XP (Pro) SP3 or later, Windows Vista (Business or

Ultimate), Windows Server 2008, Enterprise Edition, and Windows 7 (Business or better). This is a

32-bit application, however it has been tested for Windows on both 32- and 64-bit operating system

versions, and supports both in the supported Windows versions.

CAUTION:

Windows Terminal Server is not supported. The installer becomes non-responsive with Data Execution

Prevention enabled. This option is disabled by default on Windows Server 2008, but is enabled on a

Windows Server 2008 machine running Terminal Server.

Also: You must disable User Access Control if you are installing on Vista or Windows Server 2008. In

Vista, you must either to disable User Account Control or run application server as service. Another

option is to run as administrator to start application server. In Vista, right click the startappserver icon

and select run as administrator.

Finally: Installer may halt when pre-existing bash sessions or cmd sessions left are open. Close all such

sessions.

CAUTION:

This application cannot co-exist with other installations of Cygwin on the same Windows computer. Do

not install it where Cygwin is already installed, either separately or as part of another application. If

Cygwin is already installed, remove it before installing this application. If you do not see any obvious

indication Cygwin is installed (like an icon on the desktop or program list, or a directory named

c:\Cygwin), but suspect it is, you can open the registry (Start -> Run, then type

regedit

), and look for

HKEY_CURRENT_USER -> Software -> Cygnus Solutions -> Cygwin.

Linux

—

OpenManage Network Manager

supports Redhat (Enterprise version 4 & 5) and Novell

Suse (version 9 and10) Linux, 64-bit only.

CAUTION:

For Linux, you must install no more than a single instance of MySQL—the one installed with this

software. Before you install, remove any MySQL if it exists on your Linux machine.

Quick Start 7

Hardware Recommendations

OpenManage Network Manager

contains an

Application Server

that runs continuously in the

background, and a

Client

(the user interface you actually see). You can start and stop the client portion

of the software without impacting the application server. Device monitoring stops when you stop the

application server or turn off its host machine. The client can also be on a different machine than the

application server. Hardware recommendations are based on the different types of installation

available:

Full Installation (Application server + Client)

—Pentium 4, 3.2 GHz CPU, 2G RAM, and 20G

available disk space.

Client only

—Pentium 4, 2.8 GHz, 2G RAM, and 1G available disk space.

NOTE:

A browser-based client is also available. See Web Client for more information

about using web access to this software.

Basic Network Considerations

OpenManage Network Manager

communicates over a network. In fact, the machine it is on must be

connected to a network for the application to start successfully. Firewalls, or even SNMP management

programs using the same port on the same machine where this software is installed can interfere with

communication with your equipment.

Your network may have barriers to communication with this software. Dealing with such barriers,

initial device configuration to accept management, security measures or firewalls is outside the scope

of these instructions. Consult with your network administrator to ensure this software has access to the

devices you want to manage with the

Protocols

described below.

NOTE:

One simple way to check connectivity from a Windows machine to a device is to

open a command shell with Start --> Run

cmd

. Then, type

ping [device IP

address]

at the command line. If the device responds, it is connected to the

network. If not, consult your network administrator to correct this. No useful

information comes from disconnected or powered-down devices.

See

Chapter 4, Troubleshooting

in this guide or see the

User Guide

or online help, for additional

information about how to troubleshoot this software.

CAUTION:

You can click on the blue cross-references to go to the destination in Acrobat, however for such

electronic cross-references to the User Guide to work, this document and the User Guide must be in the

same directory. Cross-document links do not work between documents for different versions of this

software, but may provide an approximate location to consult.

8Quick Start

Authentication

For successful discovery of the resources on your network, this software requires authenticated

management access to the device. To get this access, you must provide the correct SNMP community

strings, and any other command-line (Telnet / SSH) or browser (HTTP/HTTPS) authentication, and

SNMP must be turned on, if that is not the device’s default. Some devices require pre-configuration to

recognize this management software. Consult your network administrator for this information.

Name Resolution

OpenManage Network Manager

server and client require resolution of equipment names to work

completely, whether by host files or domain name system (DNS). The application server cannot

respond to hosts with IP addresses alone. The application server might not even be in the same

network and therefore the host would be unable to connect.

If your network does not have DNS, you can also assign hostnames in

%windir%\system32\drivers\etc\hosts

on Windows (

/etc/hosts

in Linux). Here, you

must assign a hostname in addition to an IP address somewhere in the system. Here are some example

hosts file contents (including two commented lines where you would have to remove the # sign to

make them effective):

# 102.54.94.97 rhino.acme.com # source server

# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost

CAUTION:

This software supports installation only on the local file system. Avoid installing to shared drives.

Protocols

OpenManage Network Manager

uses the following protocols: TCP/IP, SNMP, HTTP/S, UDP

Multicast.

Fixed IP Address

OpenManage Network Manager

includes a web server and must be installed to a host with a fixed IP

address or a permanently assigned Dynamic Host Control Protocol (DHCP) lease. For trial purposes,

you can rely on a dynamic IP address assignment with a long lease, but this is not recommended for

production installations.

If you do change your host’s IP address

To accommodate a changed IP address, first delete the contents of

\oware\temp

. Change your local

IP address anywhere it appears in

\owareapps\installprops\lib\installed.properties

. Then restart your machine.

Alternatively, in a shell, after running

oware

to set the environment, you can run

ipaddresschange -n

followed by the new IP address to which you want to change.

Quick Start 9

Updating Your License

If you have a limited license — for example

OpenManage Network Manager

by default limits

discovery to ten devices — then your application does not function outside those licensed limits. If

you purchase additional licenses, put the updated license file in a convenient directory, then use the

Settings -> Permissions -> Register License

menu item to open a file browser. Locate the license file,

and click the

button. Your updated license should be visible in

Settings ->

Permissions -> View Licenses.

NOTE:

You must also re-register licenses if you have updated your installation from a

previous version where you previously upgraded licenses. In any case, you must

restart application server or wait up to 15 minutes before a license modification is

effective.

If you license new features, you must restart the application server and client.

The Application Interface

A typical screen in this software appears in

Figure 1:1

. The navigation panel to the left provides quick

access to common functions (discovery, reports, and so on), which can also be accessed through the

menus. When visible the left panel remains on screen while the main panel changes to reflect the

currently selected function.

Figure 1:1. Discovery Screen

Nodes that appear in the navigation panel depend on installed options.

Navigation Panel Main Panel

10 Quick Start

Managing Multiple Screens

The content of the Main Panel is referred to as a window. Just as you can open several documents in

your word processor, you can open several windows in this application. To see the list of windows you

have open, click the

Window

menu.

In the

Browser View

setting, you can see only one active window at a time. You cannot tile or

minimize these windows unless you select Multiple Document Interface (MDI) View (the default in

OpenManage Network Manager

) from the View -> Launcher menu.

Figure 1:2. Window Menu

If you right-click a device, for example, and select

Open

, the editor screen that appears does not close

the screen where you selected the device. Both remain open. You can navigate between screens by

selecting them in the Window menu, or with the browser buttons.

Figure 1:3. Browser Buttons and Select Layout / Select Content

The right and left arrows just left of the

Select Layout

pick list navigate backward and forward

through the open screens. To close a screen layout, click the

button to the right of the browser

buttons and layout selectors.

NOTE:

If you open more than 20 windows, the Recommended Open Windows

Exceeded error message appears. To change the recommended number, consult

the User Guide for this software. While you can still open more windows, doing so

may slow performance.
