2.2 EMS Installation Overview

The following gives an overview of what you need to do to install the

EMS:

1Install SNMPc. See the documentation that comes with your SNMPc

for information.

2Install the EMS. The PostgreSQL database will be installed during

the EMS installation.

Note: The installation program will skip the PostgreSQL installation

if you have already installed.

3Add custom MIB files in SNMPc.

4Locate device(s) that you want the EMS to manage.

5If required, configure the ODBC driver to connect to the database.

3 Installing the EMS

Follow the steps below to install the EMS server on a computer.

1Install SNMPc if it is not already

installed. See the user’s guide for

more information.

2Find and double-click

NetAtlasEnterprise_S101.exe on

your EMS CD.

3A Welcome screen displays. Click

Next to continue.

4Read the license agreement. Click

Yes to accept the agreement.

4 SNMPc Network Manager Startup

Start the SNMPc Network Manager

manually (from the Windows Start

menu) or have it start automatically

each time you turn on your computer.

To start SNMPc automatically each

time you turn on your computer, click

Config, System Startup, select

Auto Startup and then click OK.

Conversely, clear this check box if you do not wish SNMPc to

automatically start each time you turn on your computer.

5 Adding MIBs

The Management Information Base (MIB) is designed for holding

management information on systems (such as the switch that the

standard MIB does not include).

1From the SNMPc Network Manager main screen, click Config, MIB

Database.

2In the Compile Mibs screen that

displays, scroll down to the bottom of the

Mibs to Compile list box and click Add.

Note: If you have uninstalled an earlier

version of NetAtlas EMS, you must

remove zyxel.mib first.

3Select the following MIBs in the Add

Mibs list box:

• rfc2674.mib

• rfc2925.mib

• rfc3291.mib

• rfc3621.mib

• zyxel-es3124.mib

• zyxel-es3124pwr.mib.

• zyxel-es2024a.mib

EMS_Switch_V1-01.fm Page 5 Friday, September 30, 2005 3:20 PM

• zyxel-gs2024.mib

4Click OK.

5Click Compile in the Compile Mibs screen.

6Click Yes when asked to confirm, then click OK.

7Finally click Done in the Compile Mibs screen.

6 Finding your Switch

The SNMPc Network Manager can find new devices automatically using

auto-discovery (enabled by default) or you will have to add device(s)

manually.

6.1 Device Auto-Discovery

1To enable auto-discovery and then

find your device, click Config,

Discovery/Polling.

2Select the Enable Discovery check

box and click OK.

3Find your device in the Device List

panel. Double-click the device icon to

access the EMS.

6.2 Add Device(s) Manually

If you have disabled auto-discovery,

follow the steps below to add your

device(s) manually.

1Click Insert, MAP Object, Device.

2In the MAP Object Properties

screen, enter a descriptive device

name and IP address for the device

and then click OK.

7 Using SNMP

Check that you are using SNMP Version 2c (SNMPv2c). If you are not

using SNMPv2c, you must uninstall any previous versions and install

SNMPv2c. Refer to RFC 1901 for more information on SNMPv2c.

Follow this procedure to use SNMPv2c.

1Right-click the Device icon and select

Properties.

2Click the Access tab.

3Set the specified fields in the Map

Object Properties screen exactly as

shown in the figure.

Note: For security purposes, it is

strongly recommend to change

the Read Community and

Read/Write Community

defaults.

Write down this information in a secure place so you will not

forget it later!

4Click OK. After the device has been

found, the icon and label appear in

the network manager view window.

5Right-click on the device icon to view

a set of SNMPc network manager

shortcuts. Click Properties to verify

the information you entered in the

previous step.

6Make sure the PostgreSQL database

is running. PostgreSQL should start

automatically when you start

Windows. If it does not, click Start

(or start), Programs, PostgreSQL

8.0 and then click Start service.

8 Accessing NetAtlas

Follow the steps below to access NetAtlas.

1In the SNMPc main screen, double-click

the switch icon to view the Switch

Manager.

2A screen displays as shown.

Double-click the Switch Manager

configuration screen.

9 Troubleshooting

1SNMPc, EMS and/or PostgreSQL will not install properly

• Make sure that the computer on which you want to install the

SNMPc, EMS and PostgreSQL meets the minimum hardware

and software requirements.

• To install PostgreSQL, make sure your computer is using NTFS

file system.

• Shut down any services or applications that are running which

may affect the installation.

• Remove any previous versions of PostgreSQL and SNMP soft-

ware from your computer.

• Re-install SNMPc and EMS in that order.

2I cannot find my device in the SNMPc Management screen.

• Check that you have added and compiled the MIBs correctly (see

Section 5 on page 5). Make sure these instructions are followed

exactly.

• Check that you have enabled auto-discovery; see Section 4 on

page 5.

• Check that the map object properties are correct for initial instal-

lation; see Section 6.2 on page 6. Make sure the IP address

entered is the IP address of the switch you want to manage via

the EMS.

EMS_Switch_V1-01.fm Page 8 Friday, September 30, 2005 3:20 PM

NetAtlas Enterprise Ethernet Switch Manager

• Check that the ODBC driver is correctly configured; see Section

9.1 on page 9.

• Make sure that PostgreSQL is running.

• Make sure that the computer you have installed the EMS on, is

connected to the network where the switch is located.

• Make sure your computer’s Ethernet card is working properly.

• If the problem still persists, uninstall and re-install the EMS soft-

ware.

9.1 Configuring the ODBC Driver

The ODBC driver should already be installed from the EMS installation.

You must configure the ODBC driver for the EMS to connect to the

PostgreSQL database successfully.

Follow the steps below to configure the ODBC driver in Windows 2000.

Steps are similar for other supported Windows operating systems.

1Click Start, Settings and Control

Panel to open the Control Panel

screen. Double-click Administrative

Tools.

2Double-click Data Source (ODBC).

3A screen displays as shown. In the

User DNS screen, select

PostgreSQL and click Configure.

4The PostgreSQL ODBC

Driver Setup screen displays.

Configure this screen exactly

as shown in the figure. The

default password is “1234”.

5Click Save to save the

changes and close this screen.
