ProSafe Network Management System
This is a single user version for managing small to medium sized networks. ProSafe NMS can be
used on Windows 2000, 2003, NT, XP, ME, and 98 systems. All components run on a single
system and support one user. The map database size is limited to 1,000 objects.
System Requirements
The following table lists the minimum recommended system requirements.
Table 1-3. Recommended system requirements
Parameter ProSafe NMS
CPU Pentium II 600 MHz
Memory 128 MB
Disk Free 500 MB
Screen 800 x 600
Mouse Required Yes
Console Operating System Win XP/2K/2K3/NT/ME/98
Device Access Modes
ProSafe NMS supports various device access modes including TCP only, ICMP (Ping), SNMP
V1, SNMP V2c and SNMP V3. Each mode is briefly described below.
Introduction 1-3
September 2004 202-10058-01
Reference Manual for the ProSafe Network Management System NMS100
None (TCP Only)
Null access is used for polling TCP services only, where ICMP (Ping) and SNMP access is
restricted by a firewall.
ICMP (Ping)
ICMP (Ping) mode is used for devices that do not support SNMP but can still be pinged to see if
they are responding. This may include servers and workstations.
SNMP V1 and V2c
SNMP V1 and SNMP V2c are very similar SNMP agent protocols that are used by most currently
deployed network devices. Any device that supports V2c will generally also support V1. ProSafe
NMS uses automatic intelligence to switch from one mode to the other as needed. So in most cases
select SNMP V1 as the device access mode for any SNMP device.
Since SNMP V1 and V2c are the most common and simplest SNMP protocols, this guide will only
show you how to use these protocols.
SNMP V3
SNMP V3 is a secure SNMP agent protocol that supports authentication and privacy (encryption).
The use of SNMP V3 is considered an advanced topic. As such, this guide does not describe V3 in
any detail. For more information about using V3, please use the Help/Help Topics menu and
search for Setting Device Access Modes in the Index.

2-6 Installation and Startup
September 2004 202-10058-01
Reference Manual for the ProSafe Network Management System NMS100
• To remove one or more events, select the event and press the Delete key.
• To acknowledge (remove current status of) an event, select the event and use the right-click
Acknowledge menu.
• To completely clear the event log, use the File/Clear Events menu.
View Window Area
The View Window Area is the main way to view the ProSafe NMS map and command results.
This area uses the Multi-Document-Interface (MDI) specification to display multiple windows at
the same time.
Use the Window/Cascade and Windows/T ile menus to rearrange the windows in the V iew W indow
area in a way that makes them all visible.
Windows in this area can be in one of several states:
•A maximized window uses the entire area and hides any other windows behind it. If you close
a maximized window , the next top-most window wi ll still be displayed in the maximized state.
You need to be careful when using maximized windows because it is easy to lose track of how
many windows you have opened and there is an uppe r limit. Use the Windows menu to see a
list of windows. Use the Windows/Cascade menu to view all windows at the same time.
•An overlapped window does not take up the entire area. One window will be completely
visible and other windows are partially hidden behind it. This is the most common situation for
the View Window area because it lets you view maps, tables and graphs at the same time and
quickly move between them.
•A minimized window is displayed as a small title bar with window Open and Close buttons.
Windows are not typically minimized within the View Window area because, as with the
maximized case, they can easily be lost behind other windows.

Data and Statistics
Working with the Map Database
The Map Selection Tree
Locate the Selection T ool on the right side of the console. If you do not see the Selection Tool, use
the View/Selection Tool menu to show it. Select the first tab marked Map. The displayed Map
Selection Tree shows all icon objects in the map. This includes subnets (which contain lower map
levels), devices, and Goto icons. Networks and links are not shown in the Map Selection Tree.
• Single-click the small box to the left of a subnet icon (folder
icon) to open or close that sublevel in the selection tree.
• Double-click on a subnet name (right of folder icon) to open
that subnet level as a Map View window (see below).
• Left-click on any object name to select that object. Use the
Shift and Ctrl keys to select multiple objects.
• Use the Delete key to remove selected objects.
• After opening two subnet levels, select multiple device
names and drag the mouse to move them from one subnet to
another. Note that any attached links and networks are not
moved, and links will be deleted during the move (you can
re-add them manually later).
• Right-click on a device icon (colored rectangle) or name to
see the available right-click menus. Use these menus to edit
the selected object properties, display tables, and run other
custom menus.
• Open a subnet tree and use the Insert/Map Object menus, or the Edit button bar to add icon
objects to the subnet tree.
Each icon in the Map Selection Tree is colored according to the status of the represented object.
Subnet icons (and the top level Root Subnet icon) show the highest priority color of all underlying
objects.
