Power Modules

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 operation temperature of the environment does not exceed the spec. When mounting a rack-mounted switch with other operating units in a cabinet without forced ventilation, it is recommended that 1U of space is reserved between each rack-mounted switch and/or device. It is the responsibility of the user to ensure that the equipment is installed, operated, and used for its intended function in the manner specified by Moxa.

  2. Required Air Flow: Installation of the equipment in a rack should be such that the amount of airflow 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: Rack-mounted equipment should be reliably grounded and should not be removed when the equipment is energized. We suggest to use a conductor that is 0.75 mm 2 or 18 AWG and the thread diameter should be at least 3.5 mm. 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 maximum ratings, the wiring could overheat, which can cause serious damage to your equipment.

WARNING

This is a Class 1 laser/LED product. Do not stare directly into the laser beam.

Connecting the Power Inputs
The PT-G7728/PT-G7828 switches support 4 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.
  • PWR-HV-NP: one 110/220 VAC/VDC (90 to 264 VAC, 88 to 300 VDC).
  • PWR-LV-NP: one 24/48 VDC (18 to 72 VDC).

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 12 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 12 PoE+ ports (50 to 57 VDC is recommended for IEEE 802.3at devices).

In order to provide power to 24 PoE+ ports, two power modules should be used.

For the PWR-HV-NP, the 110/220 VAC/VDC power supplies provide power to the switch.

For the PWR-LV-NP, the 24/48 VDC power supplies provide power to the switch.

Wiring Requirements

WARNING
Do not disconnect modules or wires unless power has been switched off or the area is known 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.

Power Terminal Blocks

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

PWR-HV-P48/PWR-HV-NP
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/PWR-LV-NP
STEP 1: Insert the negative/positive (-/+) DC wires into the terminals.
STEP 2: Insert the terminal block connector prongs into the terminal block receptor.

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 In order to activate the redundant load sharing mode, install two power modules on the PT-G7728/G7828 Series and ensure they are both active.

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.

Relay connection Power-on state Event trigger
NO and COM Closed-circuit Open circuit
NC and COM Open circuit Closed-circuit

NOTE When wiring the relay contact, we suggest using the cable type – AWG (American Wire Gauge) 16-24 (1.31-0.205 mm 2 ) and the corresponding pin type cable terminals. The connector must be able to withstand torque at maximum 5 pound-inches. The rated temperature of wiring should be at least 105°C.

Grounding the Moxa Industrial Rackmount Switch

Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices.

NOTE Using a shielded cable achieves better electromagnetic resistance.

USB Console Connection

The switch has two types of USB port, micro USB-B console port and type A USB host port. Use a USB cable (type A male to Micro USB-B male) to connect the USB-serial console port to your PC’s COM port, and install the USB driver (available on Moxa Website) onto the PC. You can then use a console terminal program, such as Moxa’s PComm Terminal Emulator, to access the console configuration utility of the switch.

USB Storage Connection

The USB storage port is on the rear panel of the PT-G7728/G7828 switch. (Type A connector; see the diagram below for pinout assignments). Use  Moxa’s ABC-02-USB automatic backup configurator to connect to the PT-G7728/G7828 USB storage port in order to perform configuration backup, firmware upgrade, or system log file backup.

Pin Description

2 D- (Data-)
3 D+ (Data+)
4 GND (Ground)

The Reset Button

The reset button can perform two functions. One is to reset the PTG7728/G7828 switch back to factory default settings and the other is to perform a quick backup of configuration and log files to the ABC-02USB automatic backup configurator.

Reset to Factory Default Settings

Depress the Reset button for five seconds to load the factory default settings. Use a pointed object, such as a straightened paper clip or toothpick, to depress the Reset button. When you do so, the STATE LED will start to blink about once per second. Continue to depress the STATE LED until it begins blinking more rapidly; this indicates that the button has been depressed for five seconds and you can release the Reset button to load factory default settings.

NOTE DO NOT power off the switch when loading default settings.

Configuration and Log Files Back-Up

When the ABC-02-USB is connected to the PT-G7728/G7828 switch, the reset button allows for a quick back up of configuration and event logs to the ABC-02-USB. Press the reset button to start backing up the current system configuration files and event logs to the ABC-02-USB.

NOTE When the ABC-02 is plugged in, you cannot reset to factory default by pressing the reset button.
