Grid Industrial Gigabit PoE Switch | 8 PoE Downlink Ports + 2 Uplink Ports | POEJK-S8-240

Overview

The POEJK-S8-240 is an industrial Gigabit PoE+ switch with eight copper ports, a 240W PoE budget and dual-uplink design for compact DC microgrid zones. It is unmanaged, extended-temperature and built for DIN-rail, wall or shelf mounting in enclosures, mechanical rooms, warehouses and remote IDFs.

Powered from a 48–57 VDC source and housed in an IP40-rated aluminum enclosure, this switch is a solid choice when you need a small 8-port PoE+ field switch that still fits into the broader GRID DC microgrid architecture.

Key features

• Industrial Gigabit PoE+ switch – unmanaged design for simple, robust operation at the edge.
• 8 × 10/100/1000 Mbps copper ports with 802.3af/at PoE+ injector function on ports 1–4.
• 240W shared PoE budget for mixed IP cameras, APs, sensors and POE-Jack® nodes (within design limits).
• 2 uplink ports for connecting back to aggregation or core switches.
• Dual redundant DC power input (48–57 VDC), using external supplies such as POEJK-PS48-200 or POEJK-PS48-240 (sold separately).
• Wide operating temperature from -40°C to +80°C (-40°F to 176°F) for harsh environments.
• Rugged IP40 aluminum housing for industrial and light-commercial sites.
• Flexible mounting – DIN-rail, wall-mount or shelf-mount options.

Technical highlights

Ideal applications

• Small industrial or warehouse PoE zones serving cameras, APs and sensors.
• Remote telecom rooms and cabinets where extended-temperature hardware is required.
• Outdoor-rated enclosures (within IP40 limits) feeding PoE loads along a site perimeter.
• Compact DC microgrid nodes in garages, shops or mechanical spaces powered by DC supplies.

Compatibility & ecosystem

The POEJK-S8-240 sits naturally under GRID aggregation and core switches as an industrial edge node. Its 48–57 VDC power input aligns with GRID DC supplies (e.g., POEJK-PS48 series), and its PoE+ injector function on ports 1–4 makes it suitable for powering IP cameras, access points or small POE-Jack® clusters at the edge.

Use standard Cat5e/Cat6/Cat6A cabling for horizontal runs and pair with GRID’s enhanced cabling options (such as POEJC6E-CMP) where PoE++ or long bundles are involved.

Install & design notes

• Plan PoE budgets assuming the 240 W total is shared across PoE ports 1–4.
• Use redundant DC inputs where uptime is important; connect to separate 48 VDC supplies or feeds where practical.
• Mount in a ventilated enclosure or cabinet; while extended-temperature rated, good airflow improves longevity.
• Observe IP40 limits—protect against dust and moisture as required by the installation environment.

Canada-ready checklist

• ✓ Temperature range suited to many Canadian utility rooms, warehouses and sheltered outdoor enclosures (within IP40 limits).
• ✓ Ideal for small PoE zones in shops, barns and detached buildings where DC power is available.
• ✓ Compatible with common Canadian structured cabling and PoE practices.

Compatibility micro Q&A

Are all eight ports PoE?
The switch provides eight copper ports with 802.3af/at PoE+ injection on ports 1–4. Plan PoE devices on those ports accordingly.

Do I need a special power supply?
You’ll need a 48–57 VDC source such as the POEJK-PS48 family (sold separately). Dual inputs allow redundant power designs where required.
