2 Safety Information
Read the following safety information before using your Power over
Ethernet Midspan unit.
2.1 General Guidelines
Read the following safety information before carrying out any installation,
removal, or maintenance procedure on the Power over Ethernet Midspan.
Warnings contain directions to be followed for the safety of personal and
product. Follow all directions carefully.
2.2 Warnings
Read installation instructions in Section 4 before
connecting Power over Ethernet Midspan to its power
source.
Read instructions in Section 4 before connecting
Midspan-to-Midspan power backup.
Midspan must use a grounded power cord, as defined in
Section 2.3.
This product relies on the building installation for short-
circuit (over-current) protection. Use only a fuse or circuit
breaker not higher than 15A for 120VAC (U.S.), or 10A
for 230VAC (international).
Do not work on the system, connect, or disconnect
cables during periods of lightning.
A voltage mismatch can cause equipment damage and
can pose a fire hazard. If voltage indicated on the label is
different from power outlet voltage, do not connect Power
over Ethernet Midspan to this outlet.
For shelf-mounted equipment, verify surface is stable and
strong enough to support equipment. Do not stack more
than four Power over Ethernet Midspan units.
When disposing this product, follow all local laws and
regulations.
"DATA" and "DATA & POWER" ports of the Power over
Ethernet Midspan, are shielded RJ-45 data sockets. They

Copyright © July, 2011 Microsemi Page 7
Rev.A02 CPG –PoE BU
One Enterprise Aliso Viejo, CA 92656 USA
cannot be used as Plain Old Telephone Service (POTS)
sockets. Only connect RJ-45 data connectors to these
sockets.
Associated Ethernet wiring shall be limited to the inside
of the building.
2.3 Power Cord
In case power cord is replaced, replacement must meet local
requirements.
To ensure a reliable connection to an AC mains supply,
equipment provides an appliance IEC60320 inlet used for
connecting a detachable power supply cord.
Power socket outlet must be located near Midspan and
easily accessible. The only way of removing power from
unit is by disconnecting the power cord from the outlet
This unit operates under SELV (Safety Extra Low
Voltage) conditions, according to EN60950-1/IEC60950-
1. Conditions are maintained only if the equipment to
which unit is connected also operates under SELV
conditions.
2.4 Power Cord Specifications by Country
U.S.A. and
Canada
Cord must be UL-approved or CSA certified.
Minimum specification for flexible cord is:
oNo. 18 AWG
oType SV or SJ
oThree-conductor
Cord set must have a rated current capacity
of at least 10A for PD-5524G/ACDC/M, The
attachment plug must be an earth-grounding
type with a NEMA 5-15P (15A, 125V) or
NEMA 6-15P (15A, 250V) configuration.
Denmark
Supply plug must comply with section 107-2-D1, standard
DK2-1a or DK2-5a.
Switzerland
Supply plug must comply with SEV/ASE 1011.

France and
Peru
IT supplies cannot power this unit. If your supplies are an
IT type, unit must be powered by 230V (2P+T) via an
isolation transformer with a 1:1 ratio, and with secondary
connection point labeled Neutral and connected directly to
ground.
U.K
Power over Ethernet Midspan is covered by General
Approval NS/G/12345/J/100003, for indirect connection to

3 About the Power over Ethernet
Midspan
Microsemi’s family of Power over Ethernet Midspan 5524G inject power
over data-carrying Ethernet cabling. Employing these devices reduces the
need for AC outlets, local UPS and AC/DC adapters near PDs
PD-5524G Midspan supports 24 ports respectively, in a
10/100/1000BaseTx Ethernet network, over TIA/EIA-568 category 5/5e/6
cabling. 5524G can provide up to 30W (or 36W in Extra Power mode).
RPS family can provide backup or additional power to PD-5524G
products.
Power over Ethernet Midspan normally powers devices that are Power
over Ethernet enabled or are equipped to receive power over Ethernet.
These devices are called Powered Devices (PDs).
Features of the Power over Ethernet Midspan include:
Safe and reliable power over an existing Ethernet
infrastructure
Remote management using Web control and/or SNMPv3
Highest level of network security
Safe solution that protects network infrastructure
Standards compliant: IEEE 802.3af and 802.3at
Provides safe Power + Data over a single RJ45 cable
"Green PoE –50% less power is lost over Ethernet
cables"

3.1 10/100/1000BASE-TX Ports Definition
The following sections detail 5524G ports, and their functions.
3.1.1 Data Input Ports
Midspan 24 10/100/1000Base-T Data In ports, located on PoE front panel
(Figure 3-1), configured in a non-crossover manner (straight-wired).
These ports are designed to carry Ethernet data only (Tx/Rx) over:
Standard 4-wire pairs (pins 1/2, 3/6, 4/5 and 7/8)
(1000Base-T)
2-wire pairs (pins 1/2 and 3/6) (10/100Base-T)
3.1.2 Data and Power Output Ports
Midspan 24 10/100/1000Base-T Data & Power Out ports, located on the
front panel (see Figure 3-1). These ports are configured in a non-
crossover manner (straight-wired) and carry Ethernet data over:
Standard 4-wire pairs (pins 1/2, 3/6, 4/5, and 7/8)
(1000Base-T)
2-wire pairs (pins 1/2 and 3/6) (10/100Base-T)
PD-5524G series carry DC power over 4-wire pairs (pins
4/5, 7/8 and pins 1/2, 3/6)
Power over Ethernet Midspan is not a repeater; therefore maximum
distance from Ethernet switch must not exceed 100 meters (328 ft).
Power over Ethernet Midspan is guaranteed to work only within this
distance, as specified in IEEE 802.3 AT standard.
