Frequently Asked Questions - ISW-804PT-M12 Planet

How to power on the ISW-804PT-M12?

Connect the M12 power cable to the 48V DC power input (M12 A-coded 5-pin male connector). Use the supplied power cable and ensure a tight connection. The PWR 1 and PWR 2 LEDs will light green when power is applied.

What type of cable is used for Ethernet connections?

The switch uses M12 D-coded 4-pin female connectors for 10/100Base-TX. A compatible M12-to-RJ45 cable is supplied. For standard RJ45 connections, you need an adapter cable. The cable supports Auto-MDI/MDI-X.

How to mount the switch on a DIN rail?

Attach the DIN rail bracket to the rear of the switch using the provided screws. Then press the bracket onto the DIN rail until it clicks into place. To remove, press the release tab and lift off.

Can I power the switch with a different voltage?

No, the ISW-804PT-M12 requires 48V DC only. The non-PoE model (ISW-800T-M12) accepts 12-48V DC. Using incorrect voltage may damage the device.

What does the FAULT LED indicate?

The FAULT LED (green) lights when either PWR 1 or PWR 2 power input is missing. Both power inputs must be present for normal operation; the FAULT LED should be off.

How many PoE devices can I connect?

Up to 4 PoE devices can be connected on ports 5-8, each delivering up to 15.4W. The total PoE budget is 60W. Ensure total power draw does not exceed this limit.

What is the operating temperature range?

The switch operates in temperatures from -40°C to 75°C (-40°F to 167°F). Store in similar conditions. It is suitable for harsh industrial environments.

How to troubleshoot a port LED that is not lit?

Check the cable connection and ensure the M12 connector is securely tightened. Try a different port. Verify the connected device is powered on and supports 10/100Mbps. If still not lit, the cable or port may be defective.

Is the switch manageable?

No, the ISW-804PT-M12 is an unmanaged switch. It provides plug-and-play operation with no configuration required. It supports auto-negotiation and flow control automatically.

How to clean the switch?

Use a soft, dry cloth to wipe the exterior. Do not use liquids or sprays. The IP67 enclosure protects against dust and water, but avoid immersion. No internal maintenance is required.

Power over Ethernet Powered Device

3~5 Watts	Voice over IP phonesEnterprise can install POE VoIP Phone, ATA and other Ethernet/non-Ethernet end-devices to the central where UPS is installed for un-interrupt power system and power control system.
6~12 Watts	Wireless LAN Access PointsMuseum, Sightseeing, Airport, Hotel, Campus, Factory, Warehouse can install the Access Point any where with no hesitation.
10~12 Watts	IP SurveillanceEnterprise, Museum, Campus, Hospital, Bank, can install IP Camera without limits of install location – no need electrician to install AC sockets.
3~12 Watts	PoE SplitterPoE Splitter split the PoE 48V DC over the Ethernet cable into 5/12V DC power output. It frees the device deployment from restrictions due to power outlet locations, which eliminate the costs for additional AC wiring and reduces the installation time.

4. Power Over Ethernet Overview

What is PoE?

Based on the global standard IEEE 802.3af, PoE is a technology for wired Ethernet, the most widely installed local area network technology adopted today. PoE allows the electrical power necessary for the operation of each end-device to be carried by data cables rather than by separate power cords. New network applications, such as IP Cameras, VoIP Phones, and Wireless Networking, can help enterprises improve productivity. It minimizes wires that must be used to install the network for offering lower cost, and less power failures.

IEEE 802.3af also called Data Terminal equipment (DTE) power via Media dependent interface (MDI) is an international standard to define the transmission for power over Ethernet. The 802.3af is delivering 48V power over RJ-45 wiring. Besides 802.3af also define two types of source equipment: Mid-Span and End-Span.

Mid-Span

Mid-Span device is placed between legacy switch and the powered device. Mid-Span is tap the unused wire pairs 4/5 and 7/8 to carry power, the other four is for data transmit.

End-Span

End-Span device is direct connecting with power device. End-Span could also tap the wire 1/2 and 3/6.

PoE System Architecture

The specification of PoE typically requires two devices: the Powered Source Equipment (PSE) and the Powered Device (PD). The PSE is either an End-Span or a Mid-Span, while the PD is a PoE-enabled terminal, such as IP Phones, Wireless LAN, etc. Power can be delivered over data pairs or spare pairs of standard CAT-5 cabling.

How Power is Transferred Through the Cable

A standard CAT5 Ethernet cable has four twisted pairs, but only two of these are used for 10BASE-T and 100BASE-T. The specification allows two options for using these cables for power, shown in Figure 2 and Figure 3:

The spare pairs are used. Figure 2 shows the pair on pins 4 and 5 connected together and forming the positive supply, and the pair on pins 7 and 8 connected and forming the negative supply. (In fact, a late change to the spec allows either polarity to be used).

Figure 1 - Power Supplied over the Spare Pins

The data pairs are used. Since Ethernet pairs are transformer coupled at each end, it is possible to apply DC power to the center tap of the isolation transformer without upsetting the data transfer. In this mode of operation the pair on pins 3 and 6 and the pair on pins 1 and 2 can be of either polarity.

When to install PoE?

Consider the following scenarios:

• You're planning to install the latest VoIP Phone system to minimize cabling building costs when your company moves into new offices next month.
• The company staff has been clamoring for a wireless access point in the picnic area behind the building so they can work on their laptops through lunch, but the cost of electrical power to the outside is not affordable.
• Management asks for IP Surveillance Cameras and business access systems throughout the facility, but they would rather avoid another electrician's payment.

5. Troubleshooting

This chapter contains information to help you solve issues. If the Industrial M12 Ethernet Switch is not functioning properly, make sure the Industrial M12 Ethernet Switch was set up according to instructions in this manual.

The per port LED is not lit

Solution:

Check the cable connection of the Industrial M12 Ethernet Switch.

Performance is bad

Solution:

Check the speed duplex mode of the partner device. The Industrial M12 Ethernet Switch is run at Auto-negotiation mode and if the partner is set to half duplex, then the performance will be poor.

Per port LED is lit, but the traffic is irregular

Solution:

Check that the attached device is not set to dedicate full duplex. Some devices use a physical or software switch to change duplex modes. Auto-negotiation may not recognize this type of full-duplex setting.

Why the Industrial M12 Ethernet Switch doesn't connect to the network

Solution:

Check per port LED on the Industrial M12 Ethernet Switch. Try another port on the Industrial M12 Ethernet Switch Make sure the cable is installed properly Make sure the cable is the right type Turn off the power. After a while, turn on power again.
