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.

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

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

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.

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.

• 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.
