Overview1
Fig. 1.1. The NetGuardian 216T monitors alarms, pings network elements, and reports via SNMP, pager, or
email
Introduction1.1
The NetGuardian's Web Browser Interface lets you manage alarms and configure the unit through the Internet or
your Intranet. You can quickly set up alarm point descriptions, view alarm status, issue controls, configure
paging information, and more. The NetGuardian supports Internet Explorer versions 4.0 and above and Netscape
Navigator versions 4.7 and above.
Fig. 1.1.1. NetGuardian 216T has the capacity to monitor IP aware devices' network presence and also
interfaces discrete alarm points and controls at your network sites
Potential Problems using Web Interface in a Secure Proxy Network1.2
Using the Web Browser Interface for the NetGuardian in a secure proxy network can cause certain problems to
occur. If you are logged on to the NetGuardian from within your network through a proxy, and another user from
within your network tries to access the same NetGuardian, the second user will not need to login to the
NetGuardian. Both users will essentially be logged in using the same IP address because of the masking done by
the proxy server.
Some NetGuardian 216T Features1.3
NetGuardian 216T includes the following features:
T1 WAN network interface:
NetGuardian 216T supports Frame Relay/T1 for connecting two Ethernet subnets

2
Integrated 10-BaseT Hub: 7 hubed Ethernet ports reduces equipment necessary for your remote site.
SNMP v2c Support and Robust Message Delivery
NetGuardian 216T supports SNMP v2c, and the SNMP INFORM command, which permits robust delivery of
alarm notification to your SNMP manager.
Alarm Point Grouping
Each NetGuardian Alarm point can be assigned to one of eight groups, which are identified with a user-defined
label. Some of the ways you can use Alarm Point Grouping include:
Alarm Severity Levels: Configure the NetGuardian to indicate assigned alarm security
levels like Critical, Major, Minor and Status in a variable
binding within the SNMP TRAP or INFORM message — so
alarms can be sorted by severity even if your SNMP manager
doesn't support severity levels.
Two Sets of Alarm Severity Levels: With 8 alarm groups to work with, you can easily create two
different sets of severity levels. For example, you could separate
power alarms (rated from Critical to Status) from environmental
alarms (also rated Critical to Status).
Custom Virtual Alarms: Create virtual alarms based on easy formulas like All security
alarms or Critical power alarms.
Flexible Custom Derived Controls: NetGuardian 216T lets you create Derived Controls formulas
based on Alarm Point Groups.
Granular Pager and Email Notification: Selectively assign alarm points to specific pager and email
notification recipients. The NetGuardian can be configured to
send pager notifications only for Critical or Major alarms — or
you can send power alarms to repair technicians and intrusion
alarms to a security guard.
Global Support for Dual SNMP Managers
NetGuardian 216T supports sending all SNMP TRAP and INFORM notifications to two global SNMP
managers. This makes it easier to configure a secondary SNMP manager and frees up your NetGuardian
configuration for additional notification devices and more flexible alarm reporting. You can easily send an alarm
to your primary SNMP manager at the NOC; to a secondary backup SNMP manager at another location; to the
pager of the on-call technician; and the email in-box of the technician's supervisor.
Filter or Reset the NetGuardian Event Log
The NetGuardian Event Log supports the following NetGuardian 216T features:
• You can filter Event Log entries by Alarm Point Group, to see only the alarms you want.
•You can reset the Event Log, to clear old alarms from the display.
•You can reset the Event Log by Alarm Point Group; for example, clear power alarms while retaining intruder
alarms.
Alarm Sync Makes Turnup and Testing Easy
NetGuardian 216T also provides a new command to re-synchronize all alarms. This command clears all alarms,
so that a new notification is sent for all standing alarms. You can easily test alarm connections during turnup
without rebooting the NetGuardian unit.

Unit Configuration2
Logging on to the NetGuardian2.1
For Web Interface functionality, the unit must first be configured with some basic network information. If this
step has not been done, refer to the NetGuardian User Manual for initial software configuration setup.
1. To connect to the NetGuardian from your Web browser, you must know its IP address or domain name if it
has been registered with your internal DNS. Enter it in the address bar of your Web browser. It may be
helpful to bookmark the logon page to simplify access.
2. After connecting to the NetGuardian's IP address, enter your password and click Submit (see Figure 2.1.1).
Note: The factory default password is dpstelecom.
3. In the left frame there is a Monitor menu button and an Edit menu button. Most of the software
configuration will occur in the Edit menu. The following sections provide detailed information regarding
these functions.
!Hot Tip!
If the Edit menu does not appear in the left frame after logging on, it means that another station has already
logged on as the primary user. The maximum number of users allowed to simultaneously access the NetGuardian
via Web is four. The primary user is the only user with access to the editing features.
Exiting the Web interface without logging out prevents other users from accessing the Editing features, as well.
Web sessions are tracked by IP address and the session will time out after twelve minutes of inactivity, unless
configured with a longer Web timeout duration. (See section 2.14, "Setting System Timers" for more
information.)

Entering System Settings2.2
From the System screen you can enter the name, location, contact, features, and SNMP community names.
Use the following steps to define your NetGuardian system information:
1. From the Edit menu choose System (see Figure 2.2).
2. Enter the designated user name for your NetGuardian.*
3. Enter the location or address of the NetGuardian.*
4. Set the contact by entering the telephone number or other contact information for the person or group
responsible for this NetGuardian.
5. The Features field is used for entering feature codes for future upgrades. Do not change this code unless
instructed by DPS Technical Support.

Changing the Logon Password2.3
The password can be configured from the Edit menu > Logon screen > Master Password section. The
minimum password length is four characters; however, DPS recommends setting the minimum password length
to at least five characters. You can also configure security logon profiles to individual access rights in the
Logon Profile screen. (See Section 2.3.1 for logon profile configuration information.)
Note: The factory default password is dpstelecom. DPS Telecom strongly recommends that the default
password be changed.
Use the following steps to change the logon password:
1. From the Edit menu select Logon.
2. Enter the minimum password length you wish to set.
3. Enter your new password in the Password and Confirm Password fields.
4. Click the Submit Data button.
Fig. 2.3.1. Configure the password parameters from the Login screen
2.3.1 Logon Profiles and Access Rights
Creating logon profiles allows you to grant personnel access to certain functions of the NetGuardian without
allowing access to sensitive or secure areas of the database.
Use the following steps to create logon profiles:
1. From the Edit menu select Logon, then click on the Available link. (See Figure 2.3.1.1.)
2. Enter the user information in the appropriate fields. See Table 2.3.1.A for field and access privileges
descriptions.
3. Click Submit Data to save the user profile.
