Power Modules

PWR-LV-P48

Rack Mounting Instructions

1. Elevated Operating Temperature: If installed in a closed or

multi-unit rack assembly, the operating ambient temperature of the
rack environment may be greater than room temperature.
Therefore, consideration should be given to installing the equipment
in an environment compatible with the maximum ambient
temperature (Tma) specified by the manufacturer.

NOTE

In order to ensure reliable operations, please make sure the
operating temp

erature of the environment does not exceed the

spec. When mounting a rack

-mounted switch with other

operatin

g units in a cabinet without forced ventilation, it is

recommended that 1U of space is reserved between each
rack-mounted switch and/or device.

2. Required Air Flow: Installation of the equipment in a rack should
be such that the amount of air flow required for safe operation of the
equipment is not compromised.

3. Mechanical Loading: Mounting of the equipment in the rack
should be such that a hazardous condition is not achieved due to
uneven mechanical loading.

4. Circuit Overloading: Consideration should be given to the
connection of the equipment to the supply circuit and the effect that
overloading of the circuits might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.

5. Reliable Grounding: Reliable grounding of rack-mounted
equipment should be maintained. Particular attention should be
given to supply connections other than direct connections to the
branch circuit (e.g. use of power strips).

NOTE

The rackmount ears can be installed on the front or rear of the
PT-G7728/G7828 switch.

ATTENTION

Safety First

!

Be sure to disconnect the power

cord before installing and/or

wiring your Ethernet Switch. Calculate the maximum possible
current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each
wire size. If the current goes above the max

imum ratings, the

wiring could overheat,

which can cause

serious damage to your

equipment.

Connecting the Power Inputs

The PT-G7728/PT-G7828 switches support 2 types of power supply:

• PWR-HV-P48: one 110/220 VAC/VDC (90 to 264 VAC, 88 to 300 VDC),
one 48VDC PoE power input for PoE+ ports.

• PWR-LV-P48: one 24/48 VDC (18 to 72 VDC), one 48 VDC PoE power
input for PoE+ ports.

For the PWR-HV-P48, the 110/220 VAC/VDC power supplies provide
power to the switch. Separate 48 VDC power supplies are required to
provide power to all PoE+ ports (50 to 57 VDC is recommended for IEEE

802.3at devices).

For the PWR-LV-P48 models, the 24/48 VDC power supplies provide
power to the switch. Separate 48 VDC power supplies are required to
provide power to all PoE+ ports (50 to 57 VDC is recommended for IEEE

802.3at devices).

Wiring Requirements

WARNING

Do not disconnect modules or wires unless power has been
switched off or the area is kno

wn to be non-hazardous. The

device may only be connected to the supply voltage shown on the
type plate. The device is designed for operation with a Safety
Extra

-Low Voltage (SELV) or an isolated power supply, which

means that they may only be connected to

the supply voltage

connections and to the signal contact with a SELV or an isolated
power supply in compliance with IEC 60950

-1/EN 60950-

1 or UL

61010.

Power Terminal Blocks

The connection for power input and PoE external power supply is on the
power modules.

PWR-HV-P48

STEP 1: Insert the neutral/line (L/N/Ground) AC wires into the terminals.

STEP 2: Insert the terminal block connector into the terminal block
receptor.

PWR-LV-P48

STEP 1: Insert the negative/positive (-/+) DC wires into the terminals.

STEP 2: Insert the terminal block connector prongs into the terminal
block receptor.
