In today's climate, many businesses seek innovative solutions to expand their capabilities while cutting costs. Upgrading an
industrial PoE network allows for the deployment of more devices with increased
data transfer rates, reducing power consumption and lowering costs
simultaneously.
Here's how you can upgrade your industrial PoE network in
five steps.
What is Power over Ethernet (PoE)?
PoE technology allows data and power to be
transmitted to connected devices via a single Ethernet cable. Ethernet cables
contain two pairs of twisted copper wires that carry the electrical signals
needed for both.
The types of PoE and their characteristics include:
Type 1: PoE
IEEE 802.3af delivers up to 15.4 watts of power per port.
It is used for low-power devices like simple IP cameras, IP phones, and
essential wireless access points.
Type 2: PoE+
IEEE 802.3at delivers up to 30 watts of power per port.
It is used for higher-power devices like dual-band wireless points, advanced IP
cameras, and video conferencing equipment.
Type 3: PoE++
IEEE 802.3bt (Type 3) delivers up to 60 watts of power
per port and supports high-power devices such as LED lighting systems, digital
signage, and PTZ cameras.
Type 4: PoE++
IEEE 802.3bt (Type 4) delivers up to 100 watts of power
per port and supports power-demanding devices like laptops, small displays, and
thin clients.
When upgrading your industrial PoE network, checking
compatibility between newer and existing devices and infrastructure is crucial.
Newer standards are often backward-compatible with older ones.
What is a PoE Powered Device (PD)?
A PoE PD is any device that end users implement powered
via PoE, such as:
● Computers.
● Hi-powered wireless access
points.
● IP cameras.
Compatible PoE network devices are easier to install and
manage because they do not require dedicated power outlets or separate cables.
What is PoE Powered Sourcing Equipment (PSE)?
PoE PSE refers to those devices that provide power to
PDs. PoE switches and PoE injectors are common types of PoE PSE.
PoE Switches
These network switches have built-in PoE capabilities,
enabling them to power multiple PoE PDs connected to their ports.
PoE Injectors
PoE injectors are standalone devices that can add power
transmission capability to a single Ethernet cable. They enable a non-PoE
switch or wall outlet to power PoE PDs.
PoE PSEs are incredibly useful when upgrading an
industrial network that may incorporate legacy equipment.
Planning a PoE Network Upgrade
A PoE network upgrade requires preparation, including
thoroughly evaluating the existing network, identifying which components need
upgrading, and establishing a budget. The Ethernet Alliance, a global
consortium of member organizations dedicated to advancing Ethernet, has
instituted a PoE certification program to prevent compatibility issues. This
program helps users identify standard-compliant devices to ensure
interoperability.
Extend the upgrade cycle to accommodate future growth.
Increasing bandwidth can avoid unnecessary bottlenecks in the future and
prevent slow response times when the network is almost at capacity. If the
network currently uses CAT5 or CAT5e cables, consider upgrading to CAT6 or
CAT6A to meet market demand. Consider investing in an uninterruptible power
supply (UPS) to maintain operations during power outages.

Step-by-Step Instructions for Upgrading an Industrial PoE
Network
Upgrading an industrial PoE network can significantly
improve efficiency and scalability. Installation is straightforward whether
your upgrade requires managed or unmanaged switches, injectors, or other PoE
solutions.
1. Assess Network Compatibility
Identify existing devices and list all PoE PDs and their
requirements. All networking equipment must comply with IEEE standards.
2. Decide on the Right PoE Standard
Select a PoE standard that will meet the power needs of
your existing PDs and the requirements of future expansion.
3. Choose Your PoE Equipment
Choose PoE switches with the appropriate number of ports
without exceeding your power budget. PoE injectors and extenders can supply
power to individual devices and extend the reach of your PoE to remote
locations if needed.
4. Map out the Network Upgrade
Creating a detailed diagram can help visualize the new
network configuration. Calculate the total power connected to the PDs to ensure
the PSE can provide sufficient power. Make any needed adjustments.
5. Install and Power Up the New PoE Equipment
Implementing the upgrade involves a few steps to ensure
everything is connected correctly:
● Install new switches,
injectors, or extenders.
● Power up the network.
● Configure IP addresses, VLANs,
and other network settings.
● Test and troubleshoot the
network to identify and solve any issues.
Employ network monitoring tools to track performance and
identify potential problems.
Ease of Installation
Industrial-hardened PoE devices require one CAT5e, CAT6,
or CAT6A Ethernet cable to deliver power and data from the PSE to each PD. The
PSE and PD should be plug-and-play, requiring very little special equipment to
wall mount or secure in place. Some setup may be required when installing a
managed switch. Tech
support can help you with this.
Environmental Factors to Consider
Environmental factors can significantly impact the
performance and reliability of PoE deployments:
● Temperature: Temperature fluctuations and
extreme heat or cold can stress components, hinder power delivery, and lead to
premature device failure.
- Humidity: High humidity can lead to
corrosion and short circuits, while low humidity can cause static electricity,
damaging electronic components.
- Dust
and Debris:
Dust can clog cooling vents and interfere with electrical connections.
- Vibration
and Shock:
The physical stress caused by vibration can weaken cable connections, damage
delicate electronic components, and lead to signal loss.
- Electromagnetic
Interference (EMI):
EMI can degrade signal quality, causing data transmission errors.
- Outdoor
Exposure:
Rain, snow, wind, and UV radiation can affect device performance and lifespan.
