2 Introducing PowerDsine PowerView
2.1 Overview
PowerDsine PowerView is a management system for complete monitoring and
control of PowerDsine’s Power over LAN (PoL) Midspans, via an SNMP
manager or remote network management station. The system provides direct,
on-line power supervision, configuration, monitoring and diagnostics of
PowerDsine products, via their SNMP agents.
2.2 Features
PowerDsine PowerView provides a number of unique features for PoL
Midspan management:
!!!! Web-based application for remote management of Power over LAN™
devices
!!!! SNMP management capabilities for network element management
!!!! Configuration using graphical representations of remote device
!!!! Real time monitoring with visual status indicators and alarms
!!!! Events and performance data recording using trap log
!!!! System status display
!!!! Real time power parameters, in a flowing graph mode
!!!! Optional DHCP enabled-client
!!!! Runs on a PC platform with Windows graphic user interface (GUI).
2.3 System Capabilities
PowerDsine PowerView can be installed on any PC on the Local Area
Network, providing remote management capabilities of Power over LAN
devices connected to the LAN.
PowerDsine PowerView allows for monitoring and controlling at two separate
levels, as shown in Figure 2-1:
!!!! Network level
!!!! Element level.
Version 2.1 7 March 2003
SNMP
Figure 2-1: Management Deployment
2.3.1 Network Level
PowerDsine provides network management capabilities to monitor and control
an array of Power over LAN Midspans. The system is compatible with MIB
management platforms, including HP Openview and SNMPc.
2.3.2 Element Level
Element management is performed at unit and port levels.
At unit level
Midspan. These are: product identification, active power source, product status
and unit power consumption.
Parameters at port level
port status and type of powered device connected.
, parameters can be retrieved directly to the Power over LAN
include: maximum per port power, port priority level,
2.4 Security
Security is implemented in PowerDsine PowerView on three levels:
SNMP security
community field.
User privately-implemented secur ity
of each and every employee.
Password protection

Web Manager User Guide 2. Introducing PowerDsine PowerView
2.4.1 SNMP Security
Community strings provide a basic form of access control in SNMP v2
(PowerDsine PowerView is based on SNMP v2). Whenever a community
string is defined, it must be provided along with any basic SNMP query, if the
requested operation is to be permitted by the device. Community strings
usually allow read-only or read-write access to the entire device. SNMP
community authentication is part of the setup for the server. The authentication
can be changed by the user, via a console and via a Web browser.
In the absence of additional configuration options to constrain access,
knowledge of the single community string for the device is all that is required to
gain access to all objects, both read-only and read-write, and to modify any
read-write objects.
2.4.2 User Authentication
PowerDsine PowerView employs user-type authentication in order to verify the
identity of each user. The authentication is a type/password verification. An
encrypted password is allocated for each user type.
The program has defined several user types for the system. These users have
a different role and, as such, have different access authorizations. Each user
type is allocated a different scope of access control. Access definitions per
user, are listed in Table 2-1.
Table 2-1: User Authorizations
USER TYPE AUTHORIZATION

# Serial ports: COM1 or COM2 are active and available
# Access to a local network and Internet
# Null-modem cable
# Ethernet cable.
!!!! Administrative requirements
# IP address for the PoL Midspan (to be obtained from the network
manager, unless the services of a DHCP server are used)
# Internet browser installed (recommended Explorer 5.0 and higher)
# Verify your computer IP address, using one of the following:
For WIN 98
1. Go to DOS prompt (Start> Programs> MS-DOS Prompt).
2. Type the command: ipconfig, then click Enter.
3. Write down your IP address, your default gateway and the subnet
For WIN 2000 and WIN XP
1. Go to Run (Start> Run).

3.4 Starting up
Initial programming of the Midspan is automatic, as shown in paragraph 3.4.1,
hereafter. For manual programming, refer to paragraph 3.4.2.
3.4.1 Installation using the DHCP Server
PowerDsine PowerView unit default configuration is DHCP-enabled client
when logging on to the network. When starting up, the PowerView unit
configuration is that entered the last time.
$ Perform the next 5 steps:
Step 1: Connect the PoL unit to AC power and connect the null-modem
cable between the management station COM port and the PoL
RS-232 port. Connect a network cable between the PoL unit front
panel and the LAN. See the test set-up as shown in Figure 3-5.
Step 2: Wait until the command line (pSH0+>) is displayed on the screen.
Step 3: Type in ipconfig. The Midspan unit identification is displayed as:
ipaddress: nnn.nnn.nnn.nnn;
MAC address: nnn.nnn.nnn.nnn
Step 4: Record the two values for future reference.
Step 5: Proceed to paragraph 3.5 page 17, for browsing.

3.4.2 Network Interface Parameters
The next steps configure the network parameters (on a manual basis), such as
assigning an IP address to the PoL Midspan.
Notes 1. In case that you enter wrong parameter in one of the following steps,
choose (M)odify (press Enter for default), in the following option:
“(M)odify any of this or (C)ontinue? [M]”
2. The order given hereafter may be varied due to the specific operating
system.
$ Perform the next 6 steps:
Step 1: Connect the PoL unit to AC power and connect the null-modem
cable between the management station COM port and the PoL
RS-232 port. Connect a network cable between the PoL unit front
panel and the LAN. See the test set-up as shown in Figure 3-5.
