Rev. A04
The following sections outline the steps to install a typical Dell OpenManage Network Manager
system and its subsequent first use. Because the software described here is both powerful and
flexible, this quickstart cannot describe all the details of available installations. Instead, this Guide
refers to those descriptions elsewhere or in online help. It also includes a Pre-Installation Checklist,
below. A typical installation includes the following:
Installing and System Startup
Configuring Dell OpenManage Network Manager Users
Discover Your Network
Resource Management
File Management
Fault Management - Problem Diagnosis
Performance Management - Troubleshooting
Pre-Installation Checklist
The following helps you avoid trouble in your Dell OpenManage Network Manager installation.
Select devices (IP addresses) and ports to monitor.
Select IP address for your server.
• Configure its IP address as a management station and receiver of SNMP traps on each
Determine IP range of devices being discovered.
Verify firewalls have open ports between devices and your server. Best practice is to take down
the firewall, install the application, then put it back up.
Review device documentation and release notes.
Other Software to Install
Install these: ActivePerl (then reboot your host), Latest Adobe Flash player, Latest Adobe Reader.
You will also need access to an FTP / TFTP server.
You must disable User Account Control if installing on Windows Server 2008. Temporarily disable the
system firewall or any anti-virus software prior to installing, too. Install this software and the wizard will
walk you through initial setup. Dell OpenManage Network Manager installs as a service and starts
automatically. Refer to the User Guide and release notes for additional setup information.
Installation host—Log in as an administrative user. An administrative user can write to the
installation target directory. Do not log in with user name admin, administrator, or a name
that contains spaces on Windows, or as user root on Linux
Windows 2012 —When installing on this platform, right click win_install.exe and select
Properties > Compatibility. Select compatibility mode for Windows 7 /Vista.
Directories—The source directory should not be the same as installation target directory
Fixed IP Address—Dell OpenManage Network Manager requires a static IP address.
You must have root access to install on Linux, but do not install as user root (or user dorado).
Starting Dell OpenManage Network Manager (After installation)
Database Running, Connected—Make sure your database is running. MySQL installs
automatically as a service (daemon).. Do not install on Linux with MySQL already installed
(uninstall any included MySQL first).
Start Application Server—If you installed this software as a service and application server is
down, in Windows right-click the startappserver icon, and start application server. This icon
may prematurely indicate application server has started. Workaround: Wait a little, and the
application server will catch up to the icon.
When initiated from the tray icon, startup changes its color from red to yellow to green, when
complete. Once the icon has turned green, the web client may display the message “The
server is currently starting up. This page will refresh when the server has fully started.” This
message indicates the application server requires extra time to start. When the message does
occur connect the web browser again after a few minutes.
Login—Default Dell OpenManage Network Manager login is admin, password admin.
The first time you start the application after you install it, you may have to wait some additional minutes
for Application to completely start. One indication you have started viewing your web client too soon is
that the Quick Navigation portlet does not appear properly. Workaround: Force Redcell to re-initialize the
admin user. To do that: Login as Admin. Go To > Control Panel > Users and Organizations. Select and edit
the Admin user. Edit any field (Middle Name for example). Save. Sign out. Log back in with admin.
For Successful Discovery (After startup) Have the Following:
Connectivity—Ensure application server has connectivity to devices to discover. One easy way to
do this is to ping the discovery target from application server.
Device Login/Passwords— Needed for discovery targets. Typically these include SNMP
communities and CLI login / password combinations. Determine what version of SNMP you
are using, too.
Device Access—Insure Dell OpenManage Network Manager’s host is authorized to manage to the
device(s). When necessary, configure devices’ ACLs to admit this application’s access /
Backup / Restore / Deploy (After device discovery)
FTP/TFTP Server—Make sure an external FTP/TFTP server is running and has network access to
the target device(s). Typically FTP/TFTP servers must be on the same side of firewalls as
managed devices. Dell OpenManage Network Manager’s internal FTP/TFTP server is for
testing only. If these are separate processes, configure them so they write to the same
Alarms / Monitoring
Minimize Network Traffic—Configure “chatty” devices to quiet down. Use Suppress Alarms to
keep performance at acceptable levels, and configure database archiving so the database does
not fill up.
Some Dell OpenManage Network Manager features do not work without internet access. In particular:
Maps, because the maps Dell OpenManage Network Manager uses need internet access to retrieve maps
and plot locations. But if you do not need functioning map portlet(s), then running Dell OpenManage
Network Manager without internet access works well as long as the network is properly configured and
resolves the localhost name to application server’s IP address.
Licenses and Upgrades
Dell OpenManage Network Manager 5.3 can only be installed as an initial installation or upgraded
from version 5.0 or later.
Recovering licenses—Dorado Software can provide licenses to replace any lost or misplaced
licenses on request. This can be done by contacting your sales representative or going to http:// Refer to the User Guide and Release Notes for
additional information.
You can contact the Sales rep that provided the license, contact Dorado Software, call the Dorado
Software help desk, or submit a trouble ticket requesting a license upgrade.
When you license new features, you must restart the application server.
Installing and System Startup
Initiate installation by clicking Install by executing the shortcuts to win_install.exe
[Windows], or [Linux] in the installation root directory. Click through the
installation wizard, accepting the license and making the appropriate entries.
During installation, one screen lets you select the application’s memory size. Best practice is to
select the largest available after 1 - 4 GB is set aside for the operating system.
You can re-set the selected memory size after installation too, with the following properties in
When you have installed and successfully deployed Dell OpenManage Network Manager, you can
continue to the next steps. See the Installation and Startup section of the Dell OpenManage
Network Manager User Guide for step-by-step instructions for a typical installation. For more
complex installations, consult the Dell OpenManage Network Manager’s Administration Section
of the User Guide.
Finally, you must do the following to see Dell OpenManage Network Manager:
If your application server is not running, manually start it. You can use the Start > Programs
> Dell OpenManage Network Manager menu in Windows, or simply type
startappserver in a command shell.
If it is installed as a service, and the tray icon is red, right-click that icon and select
Start. Application server monitors your network even when the client is not running.
If it is not already running, start the web server. Right-click the tray icon for web server
and select Start service.
On Linux start (or stop) the webserver with scripts start (or stop) located in
the oware/synergy/tomcat-x.x.x/bin directory.
To see the client interface, open a browser, and enter this in the URL field:
http://[hostname or host IP address]:8080.
Internet Explorer 9 or above, if set up in compatibility mode with Internet Explorer 7 or
Internet Explorer 8 has difficulties rendering the user interface.
Log in for the first time as admin (password admin).
Dell OpenManage Network Manager should appear with the standard set of page
configurations for your package. You can typically reconfigure these defaults. See the User
Guide for guidance about how to do that.
Instead of oware, in Linux systems type . /etc/.dsienv —[dot][space]/etc/[dot]dsienv)
Configuring Dell OpenManage Network
Manager Users
As an Administrator, you can configure Users, and Roles to identify support teams (examples:
administration, engineering and operations) and configure permissions. After creating them, add
Users to roles which configure their permissions for access and action. The following describes how
to do this.
Add Users and connect them to Roles
Add Users with the following steps:
Click Go to > Control Panel and navigate to Portal > Users and Organizations.
Click the Add > User menu item at the top of the Users and Organizations screen.
Enter the details of the new user. If you are editing an existing user, more fields appear. Screen
Name, and Email Address are required. Optionally, you can enter Name, Job Title, and so on.
After you click Save notice that the right panel expands to include additional information.
Make sure you specify a Password.
Notice that if you are editing an existing user, or creating a new one, you can use the links on
the right to configure connections with Roles. Roles, in particular, configure the Dell
OpenManage Network Manager functional permissions for that user. For example the group
of Operators would likely have more limited capabilities than Administrators.
Click Save again, and the user you just configured should appear listed in the Users and
Organizations screen when you select View > All Users.
To assign a user to a role, click Action > Permissions and check the appropriate box next to
the role. Configure Dell OpenManage Network Manager functional permissions for these
roles in Roles.
Add and Configure User Roles / Permissions
Add and configure User Roles with the following steps:
Click Go to > Control Panel and navigate to Portal > Roles.
Click the Add tab under the heading at the top of the page, and select Regular Roles. Notice
that you can also add roles that configure permissions for sites and organizations.
Enter the details of the new role (Name, Title, Description), then Save it.
Click Portal > Roles’ View All button to see a list of available roles, including the one you
By clicking the Action icon to the right of any listed Role, you can also select the role’s
permissions to alter web portal access in a subsequent screen.
Click Add to add permissions. Click the checkboxes to enable the type of permission desired.
To do more with Dell OpenManage Network Manager’s functional permissions, go to the
Redcell > Permission Manager, and click to open this screen.
The Role to Permission mapping screen appears. Click the Edit button to the right of listed
Roles to see and configure available permissions.
Click Advanced to see available permissions organized by Read, Write, Execute, Add or Delete
After you have selected permissions, click Apply to accept them and add them to the role.
Notice that you can revisit this role, manage it and its membership with the Action button to
the right of the role. You can also add users to the group by selecting and editing that user.
The first time you start the application after you install it, you may have to wait an additional five minutes
for Application to completely start. One indication you have started too soon is that the Quick Navigation
portlet does not appear properly. Also: Web server may indicate it has fully started before it is entirely
ready. In rare instances, this may also inhibit correct communication with the client interface. If Dell
OpenManage Network Manager appears stuck after application server is running completely, restart the
web server.
Discover Your Network
To begin managing resources in your network, you must discover them to store their information in
the application database. This begins either with the Resource Discovery Quick Navigation button
or the Discovery Profiles portlet.
Discovery profiles configure
equipment discovery for Dell
OpenManage Network Manager.
The summary view displays the
Name, Description, Default (the
green check indicates the default
profile), whether the profile is
Scheduled and Next Execution
Date for scheduled discovery.
Follow these steps to start
discovering equipment on your
Click the Resource Discovery button in Quick Navigation or right-click the Discovery Profiles
list and select New. (If you have previously exported profiles, you can Import them. You can
also Export Selection, or Export all profiles in this manager. Open an existing profile to edit
After this beginning, if you clicked the Resource Discovery button, the Quick Discovery
screen appears where you can enter device identifiers (typically IP Address(es)), and
authentications, then execute discovery. The Quick Discovery screen can also discover the
default Discovery profile if you have configured one already.
If you clicked New in the Discovery portlet, the Discovery Profile Editor appears, with a stepby-step set of screens to configure resource discovery, as described below.
You can navigate through the Profile Editor by clicking the screen tab names at the top, or by
clicking the Next button at the bottom of the page.
Discovery Profile Editor
Use this editor to configure discovery. Follow these steps to discover equipment on your network:
General Parameters—Set the Name, Description.
Profile Options—Select the Device Naming Format (how the device appears in lists, once
discovered), whether to Manage by IP address or hostname, and check whether to Resolve
Hostname(s), ICMP Ping Device(s), Manage ICMP-only Device(s), or Manage Unclassified
Device(s). This last checkbox determines whether Dell OpenManage Network Manager
attempts to manage devices that have no device driver installed. Management may be
possible, but more limited than for devices with drivers installed, provided this capability is
one you have licensed.
The Filters (by Location, Vendor, or Device Type) let you narrow the list of devices discovered
by the selected item(s). As the screen says, this filtering will not have any impact on the
processing that occurs during the Inspection step.
Model numbers may change when you upgrade. You may need to change any pre-existing filters that
refer to model numbers. These may not change until you perform a resync on some devices.
After you click Next, the Network screen appears.
Network Type and Addresses— Select the type of entry in the pick list (IP Address(es),
CIDR Address, Hostname, SNMP Broadcast, Subnet).
You can specify an IP Address range by separating the beginning and end with a dash. For example:
The tooltips in the data entry field describe what valid entries look like.
Authentication—You can Create new, or Choose existing authentications. Notice that
authentications appear with Edit / Delete icons and Up / Down arrows on their right. The
Edit icon opens the authentication editor. Click the arrows to arrange the order in which
credentials are tried (top first). Ordering only applies when two credentials are of the same
Discovery can fail because of network latency / timeout issues. Increasing the timeout or retries for Dell
OpenManage Network Manager authentications can circumvent that.
You can configure Actions to run as part of discovery. By default, the actions screen includes
several, including the Resync action. Use Add Action to select others to enter here. You can
also edit parameters (if available), delete and re-order the actions listed here by clicking the
icons to the right of them. Dell OpenManage Network Manager executes them in top-tobottom order.
Inspect Network using your current settings—This screen lets you preview the discovery
profile’s actions and access to devices. If you clicked Next rather than Inspect at the bottom of
the previous screen, click Start Inspection to begin the inspection process for selected
authentications that validates the device’s credentials.
Notice that the Auth Test Status fields below listed authentications indicates the success or
failure of Ping, Hostname resolution, and the listed Authentications.
If the device does not match all required authentications, you can click the Fix it icon
(wrench and screwdriver crossed) to edit them for the selected device. You can also click Test
Device, Create New, or Choose Existing authentications while in the editor clicking the Fix it
icon displays.
When authentications are unsuccessful, you can remove or edit them in this editor too. Click
the icons to the right of listed authentications to do this.
Save—Click Save to preserve the profile. You can then right-click it to select Execute and
begin discovery. If you select Execute from the profile editor, Dell OpenManage Network
Manager does not save the profile to execute later.
Execute—Clicking Execute begins discovery, and the message traffic between Dell
OpenManage Network Manager and the device appears on the Results screen.
This is a standard Audit screen.
A message (Discovery Profile Execute is complete) appears in the Messages at the bottom left
of the status bar.
You can also schedule discovery profiles to run periodically, updating your Dell OpenManage Network
Manager database with any network changes.
The devices in your network now appear in the Resource Management portlet, and elsewhere
(in Topology, for example).
Resource Management
The Managed Resource portlet
displays all the devices you have
Right-clicking a listed resource
displays a menu with options
described in the User Guide.
