bedrijfsnieuws over Ubiquiti Poe Solutions Simplify Network Power Management

Network administrators face a nightmare scenario when carefully deployed equipment suffers from insufficient power supply, leading to frequent disconnections, degraded performance, and disrupted business operations. Ubiquiti's Power over Ethernet (PoE) solutions provide the perfect remedy for these challenges. This article explores Ubiquiti's PoE modes, power requirements, and device compatibility to help build stable and reliable network infrastructure.

Before examining Ubiquiti's specific products, it's essential to understand the primary PoE modes. Different PoE modes vary significantly in power output, voltage, and supported cable types. Selecting the appropriate mode is crucial for ensuring stable device operation.

PoE (IEEE 802.3af): As the original PoE standard, Type 1 PoE delivers 15.4W per port, with 12.95W available for devices. It suits low-power equipment like IP phones, small wireless access points, and basic cameras.

PoE+ (IEEE 802.3at): Type 2 PoE+ provides 30W per port (25.5W available), meeting the needs of medium-power devices such as advanced wireless access points, PTZ cameras, and access control systems.

PoE++ (IEEE 802.3bt): Type 3 PoE++ offers 60W per port (51W available), supporting high-power devices including performance wireless access points, video conferencing systems, and digital signage.

PoE+++ (IEEE 802.3bt): Type 4 PoE+++ delivers 100W per port (71W available), capable of powering demanding equipment like large LED lighting, high-performance PTZ cameras, and virtual reality devices.

Ubiquiti offers various switch models with differing PoE support. The following table summarizes PoE compatibility across Ubiquiti's mainstream switches to help users make informed selections.

Lite Series: Ideal for small networks, supporting PoE and PoE+ for basic power needs.

Standard Series: Suitable for small-to-medium networks with PoE and PoE+ support.

Professional Series: Designed for medium networks, adding PoE++ support for higher-power devices.

Pro Max Series: For medium-to-large networks with similar PoE support as Professional but greater total power capacity.

Enterprise Series: Enterprise-grade with PoE and PoE+ support, emphasizing stability and reliability.

Enterprise Campus Series: Comprehensive PoE support for large campus networks, including all PoE modes up to PoE+++.

Understanding device power requirements is essential for proper PoE budget planning. Below are typical power consumption values for common Ubiquiti devices.

PoE available power refers to the total power a switch can allocate to connected devices. For stable operation, this must exceed the combined power consumption of all devices. Below is the range of PoE available power for Ubiquiti switches.

When planning PoE budgets, it's advisable to include some power reserve to accommodate fluctuations or future expansion needs.

For networks without PoE switches or where switch power is insufficient, PoE adapters (injectors) provide an alternative solution. These devices combine power and data signals through a single Ethernet cable to power connected equipment.
