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.

PoE Power Terminal Blocks

STEP 1: Insert the negative/positive DC wires into the -/+ terminals,

respectively.

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

block receptor.

NOTE

In order to have higher levels of protection against surge, it is

suggested to install a surge protector in front of the power input

of the

PoE powered device so that it is suitable for use in IEC

61850 conditions.

NOTE

When wiring the power input, we suggest using the cable type -

AWG (American Wire Gauge) 18 (1.03mm2) and the

corresponding pin type cable terminals. The connector must be

able to withs

tand torque at maximum 5 pound-

inches. The rated

temperature of wiring should be at least 105°C.

NOTE

When installing 2 power units on the PT-G7728/G7828 switch,

only power 1 (installed in the upper slot) will activate and provide

power. The other power

unit, power 2 (installed in the lower slot)

will be on standby.

NOTE

The reverse power input connection will not activate the device or

PoE input

. In addition, the PoE will only activate when

the system

power input is installed on the same power unit.

Wiring the Relay Contact

Each power module has one relay output that can provide two types of

relay output. Refer to the table below for detailed information.

The relay contact is used to detect user-configured events. Two wires are

attached to the relay pins with normally close and normally open options.

FAULT:

The relay contact of the 3-pin terminal block connector is used to detect

user-configured events. The module provides normally open and

normally closed circuits depending on what the user chooses. For pin

definitions refer to the table below.
