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

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

actual device in addition to information tables. The system provides several
views:
!!!! Graphical view of the device monitored
!!!! Alarms/notification table for the device being monitored
!!!! Properties of the management system.
The GUI authorizes program access options to management users, according to
their passwords. The system administrator carries highest privileges, followed by
the supervisor. The operator has lowest privileges. In order to log in and work
with the GUI, the installation process, described in Section 3, must have been
performed in its entirety.
4.2 Logging in
PowerDsine PowerView manages a single unit at a time. More than one unit can
be managed using standard management platforms, such as: HP Openview,
SNMPc and similar platforms.

The graphical display panel includes a number of visual indicators for operating
power input and output ports.
4.4.4.1 Power indications
Two LEDs on the front panel, marked by “AC” and “DC”, provide the Power over
LAN Midspan power status. When either one of the indicators is illuminated in
green, the Power over LAN Midspan is receiving AC or DC power. The “AC” and
“DC” indicators are lit in orange to indicate an internal fault. Refer to Table 4-1
for additional information.
Version 2.1 25 March 2003

4.4.4.2 Port status
One bi-color indicator (green and orange), per port, provides port status:
!!!! Green indicates that the terminal unit has been identified as "Power over
LAN Enabled" and is active and receiving power.
!!!! Orange indicates that the port is not supplying power and is not active.
Refer to Table 4-1 for additional information.
Note Due to the standard detection process performed on each PoL port, power
will not be supplied to an Ethernet device, that is not PoL-enabled (indicated
in orange or off). In this way, Ethernet devices (not PoL-enabled) will not be
affected by this connection.

4.6 Viewing Trap Log Entries
4.6.1 About Traps Recording
PowerDsine PowerView includes an internal SNMP trap handler which records
SNMP traps addressed to it. A trap is sent when the status of a device changes.
Traps are unsolicited messages, such as a port sensing its PD was
disconnected or main AC power switching to standby (DC power source).
Figure 4-7 displays a number of traps recorded by the application program. The
individual trap listings compose a file started the moment PowerDsine
PowerView initates the connection between the PoL unit agent and the SNMP
manager. File content is limited to 5000 messages.
Once the connection is terminated, this log file is erased. The operator can
choose to copy the file at any time.
Note Communication problems of the managed device with the manager will be
indicated by Red error messages.

6.1 Architecture
There are three types of software associated with the Power over LAN (PoL) Midspan):
1. PoL device software - embedded into the PoL Midspan‘s motherboard
operates the PoL functionalities.
2. Management software - installed in the SNMP daughter board (agent).
This is the management software.
3. GUI software - also located in the SNMP daughter board.
A TFTP server stores all the software types (refer to paragraph 3.6, page 19).

7 Useful Information
7.1 SNMP Background
The Simple Network Management Protocol (SNMP) is a standard that allows
management data on different network devices to be read and monitored, as
well as controlled by an application. PowerDsine PowerView monitors and
controls SNMP objects on any device implementing an SNMP agent.
7.2 SNMP Protocol
SNMP is based on the manager/agent model. SNMP is referred to as "simple"
because the agent requires minimal software. Most of the processing power
and the data storage resides on the management system, while a
complementary subset of those functions resides in the managed system.
To achieve its goal of being simple, SNMP includes a limited set of
management commands and responses. The management system issues
Get, GetNext and Set messages to retrieve single or multiple object variables
or to establish the value of a single variable. The managed agent sends a
response message to complete the Get, GetNext or Set. The managed agent
also sends an event notification, called a trap to the management system to
identify the occurrence of conditions, such as a threshold that exceeds a
predetermined value. In short there are only five basic operations:
get (retrieve operation)
get next (traversal operation)
get response (indicative operation)
set (alter operation)
trap (asynchronous trap operation).
7.3 Outline of the SNMP protocol
!!!! Each SNMP managed object belongs to a community
!!!! NMS station may belong to multiple communities
!!!! A community is defined by a community name, that is an OctetString with
0 to 255 octets in length.
!!!! Each SNMP message consists of three components:
# version number
# community name
# data - a sequence of PDUs associated with the request.

SNMP
7.3.1 Management Information Base (MIB)
The MIB contains the essential objects which compose the management data
for the unit. The MIB defines the objects to be managed for a TCP/IP network
and provides a format for each object.
The MIB is defined as an object tree, divided into logically related groups of
objects, such as: system, interfaces, ip, tcp, udp, snmp, etc… The MIB
provides for an extensible design to add public and private objects.
7.3.2 Security
The community profile provides for limited security when accessing the unit’s
data. A community name is assigned within the SNMP agent or manager. The
network management application can access data on the unit, only if its knows
the community name. The unit’s software will allow the user to specify the IP
address for which requests will be accepted.
7.3.3 SNMP Agent
The software for an SNMP agent or manager is installed on the unit which is to
receive SNMP information. As such, an SNMP agent is provided by Windows
and by system manufacturers.
7.3.4 Traps
A limited number of unsolicited messages or traps, are sent from a unit to an
SNMP application. These messages, sent by an SNMP agent on the unit, can
notify an SNMP application of a change in status.
7.3.5 Operations
An SNMP application can read values for the SNMP objects -to monitor unitsand some applications can also modify variables –for remote management of
units. Basic operations include:
!!!! Get – gets a specific SNMP object for a unit
!!!! Get next – gets the next object in a table or list
!!!! Set – sets the value of an SNMP object on a unit
!!!! Trap – sends a message about an event to the management application.
