xii About this Guide
How to Use This Guide
Using the Matrix N Series Manual Set
The Matrix N-POE Series of switches support PoE-compliant 48 Vdc/data connections
through the same cable, to remote powered devices (PDs) such as telephones, fax
machines and other devices that meet PoE standards. The N-POE Series switch manuals
explain how to install the switch, connect the 48 Vdc/data cables to the external powered
devices (PDs), and configure the switch using command line interface commands
described in the Matrix DFE Series Configuraton Guide.
Each manual is written for qualified personnel who are responsible for installing the
switch device and also have a general working knowledge of data communication
networks and their physical layer components.

•N-POE PSM refers to the N-POE-1200 W DC power supply module.
•PoErefers to the Power over Ethernet (802.3af) compliance standard.
• PoE switch module refers to a DFE Series PoE-compliant switch module.
•PD refers to powered devices, which can operate using 48 Vdc received through new or
existing Ethernet data cable.

N-POE Power System (NPS) Overview
1-2 Introduction
N-POE Power System (NPS) Overview
The N-POE Chassis can house up to four N-POE PSMs to provide an N-POE Power
System to meet your needs and can consist of the following components:
• One N-POE Chassis
• One to four optional N-POE PSMs. Each are shipped with their own AC power cord.
• One to seven optional DFE-POE-CBL-2M Cables
The NPS enables you to expand the capability of the Matrix N3 and Matrix N7 chassis to
operate Enterasys PoE switch modules, which support connections to powered devices
(PDs). This is accomplished by providing the 48 Vdc necessary for the PoE switch
modules to support 48 Vdc/data connections to powered devices (PDs).
The N-POE Chassis and N-POE PSM are shown in Figure 1-1 and Figure 1-2, respectively.

N-POE Chassis
Matrix N Series N-POE Power System Installation Guide 1-3

N-POE Chassis
The N-POE Chassis features include the following:
• Supports up to four N-POE PSMs in an N+1 configuration (if two or more
N-POE PSMs are installed and one fails, power is provided by the remaining
N-POE PSMs).
• Easy front panel access to seven D-Sub 48 Vdc, 25 A connectors that can provide
power for up to seven PoE switch modules residing in an N3 or N7 chassis.
• Easy access to circuit breaker/reset switch for each 48 Vdc, 25 A output.
• Separate AC power inlet connectors for each N-POE PSM installed.
• Installs in a standard 19-inch rack to provide maximum wiring closet port density.
Optional N-POE Power Supply Module (N-POE PSM)
The N-POE PSM features include the following:
• Hot swappable capability as long as the total power needed does not exceed the
power output capability of the remaining N-POE PSMs in the N-POE Chassis.
• Provides a maximum power output of 1200 W to PoE switch modules. The maximum
number of PDs supported by each PoE switch module is dependent on the PD power
consumption as indicated by their Power Classifications. For details about Power
Classification, refer to “Powered Devices (PDs)” on page 1-4.

N-POE PSM Status LEDs
1-4 Introduction
• Provides power redundancy when two N-POE PSMs are installed in the
N-POE Chassis and there is no more than a 1200-Watt demand by the connected DFE
series switch module to support PDs. So if one N-POE PSM fails or is removed from
the chassis, the other N-POE PSM can support the total load.
• Provides continuous power sharing by all N-POE PSMs when two or more are
installed in the N-POE Chassis. Up to four N-POE PSMs can be installed in the
N-POE Chassis to provide up to 4800 Watts of power.
N-POE PSM Status LEDs
There are two status LEDs (AC power LED and DC power LED) on each N-POE PSM. The
AC power LED is green when the N-POE PSM AC power input is within specifications
and turns off when it is not. The DC power LED is green when the N-POE PSM 48 Vdc
output is within specifications and turns off when it is not.
Powered Devices (PDs)
PDs are devices that receive their operating 48 Vdc power through a new or existing
Ethernet cable from a switch or other device that can provide a PoE-compliant port
connection. This enables the PD to operate in a location without local power. For example:
• Devices such as PoE-compliant remote EXIT signs and Personal Data Assistants
(PDAs),
• Devices that support Voice over IP such as PoE-compliant digital telephones,
• Devices that support Wireless Application Protocol (WAP) such as security cameras,
laptop PCs, and many more devices.
Each device is rated according to a PoE Power Classification assigned by the
manufacturer. If you know the classification of the PDs connected to your system, you can
approximate the total amount of power needed to operate the PDs and plan accordingly.
Power Classifications and Deployment
The number of N-POE PSMs needed to power the PoE-compliant PDs is dependent on
their Power Classifications. Each N-POE PSM can supply up to 1200 Watts of power. You
can determine the number of power supplies needed by referring to Table 1-1 and adding
up the maximum power requirement according to the Power Classification rating
(1 through 3) of each PD. Keep in mind that each classification represents a range of
power, so your maximum calculation represents a worst-case power consumption, so the
actual power consumption could be less.
