Grid POE-Jack® 48-Port Ultra90 PoE++ Core Switch | 3600W Power Budget, 100G Uplinks | POEJK-S48-3600

"

Overview

The POEJK-S48-3600 is a 48-port Gigabit Ultra90 PoE++ core switch with a massive 3,600W PoE budget, designed to act as the central “power plant” in GRID DC microgrid designs. It is built for consultants, electrical engineers and integrators who need to power dense fields of Active POE-Jack® in-wall switches, PoE lighting, wireless access points, cameras and building automation from a single chassis.

This switch anchors Convergent Edge and zone cabling architectures: one high-power port feeds an Active POE-Jack® in the wall, which then fans out to multiple IP devices locally. That approach can reduce home-run cabling, patch panels and tray sizes by up to roughly 75% compared with legacy four-drops-per-desk designs, while centralizing DC power where it is easier to back up and monitor.

If you’re looking for a 48-port PoE++ switch for Active POE-Jack® projects in Canadian offices, campuses, healthcare or hospitality buildings, the POEJK-S48-3600 is the flagship core platform in the GRID ecosystem.

• Redundant, hot-swappable power – load-sharing, hot-swappable dual AC PSUs (C14 inlets) to keep the DC microgrid online during maintenance or PSU failure.
• Serviceable thermal design – hot-swappable fans with front-to-back (AFO) airflow for predictable cooling in dense racks and telecom rooms.
• Carrier-class switching fabric – up to 696 Gbps switching capacity with flow-based telemetry for detailed visibility and anomaly detection.

Ideal applications

• Enterprise and campus cores powering large numbers of Active POE-Jack® in-wall switches and PoE zones.
• Smart buildings with PoE-powered lighting, blinds, sensors and room controllers on a converged low-voltage backbone.
• High-density Wi-Fi and small-cell deployments that need many ports to sustain higher PoE++ loads at once.
• Hospitality, casinos and resorts consolidating cameras, guest Wi-Fi, digital signage and access control on a single DC microgrid.
• Education and healthcare campuses seeking LEED-aligned designs with less copper, fewer IDFs and simpler MAC (moves/adds/changes).
• Industrial and mixed-use buildings where uptime, timing and telemetry are required for IT/OT convergence.

Compatibility & ecosystem

The POEJK-S48-3600 is purpose-built to anchor GRID Networking projects that use Active POE-Jack® in-wall switches, GRID Cat6e/Cat6A cabling and PoE-powered endpoints. One PoE++ port feeds a single Active POE-Jack®; that jack then locally switches four devices at the wall, drastically reducing home runs, patch panel density and conduit sizing in the riser.

It supports mixed fleets of PoE devices (802.3af, 802.3at, 802.3bt) including IP cameras, Wi-Fi access points, VoIP phones, access control panels, PoE lighting controllers, signage players and room-control devices. In multi-switch designs it can operate as a building core with POEJK-S48-740 and POEJK-S48-750E switches at the floor or edge for a fully tiered DC microgrid.

Install & design notes

This switch concentrates significant PoE power in a compact 1U chassis. Plan for dedicated rack space with clear front-to-back airflow and follow manufacturer guidance for branch circuit sizing, UPS integration and grounding. Because the PoE budget is shared, not every port can run at maximum PoE++ power simultaneously—integrators should calculate realistic power budgets for each project and leave headroom for growth.

In Canadian commercial projects, this unit typically lives in an MDF or main electrical room alongside UPS and fire alarm panels. It is often paired with 23 AWG Cat6e permanent links to POE-Jack® nodes for better voltage delivery and thermal performance in bundles. Coordination between IT, electrical and mechanical trades is recommended so that cooling, power and cabling all align with the DC microgrid design.

Compatibility micro Q&A

Q: Will this work with standard PoE and PoE+ devices?
Yes. The POEJK-S48-3600 supports IEEE 802.3af (PoE) and 802.3at (PoE+) alongside 802.3bt/Ultra90 PoE++, so it can safely power legacy and modern endpoints in the same project.

Q: Do I need PoE++ devices to justify a 3,600W core switch?
No. Many deployments use a mix of PoE, PoE+ and PoE++ endpoints. The high budget ensures that heavily loaded POE-Jack® clusters, lighting and AV devices can coexist without running out of power.

Q: Can this replace my existing campus core switch?
In many designs it can, provided your uplink, Layer 3 and redundancy requirements are met. It is often deployed as the PoE/DC microgrid core with uplinks into an existing non-PoE routing core if desired.

Q: Is this overkill for a small building?
For smaller sites or single floors, many teams prefer the POEJK-S48-740 or POEJK-S48-750E. The 3,600W model is typically reserved for larger campuses, high-density PoE++ projects or where future expansion is planned.

FAQ

Q: How many Active POE-Jack® units can this realistically support?
The exact number depends on each jack’s downstream load, but the 3,600W budget is specifically sized so large projects can power many POE-Jack® units at practical PoE++ power levels. Your integrator or engineer should run a detailed PoE budget for each design.

Q: How does this support LEED and sustainability goals?
By centralizing DC power and pairing with Active POE-Jack® and 23 AWG cabling, you can materially reduce copper, trays and local AC outlets. This “dematerialization” supports LEED-aligned strategies around reduced materials, efficiency and flexible low-voltage infrastructure.
