Grid POE-Jack® 48-Port PoE+/PoE++ Switch | 750W Budget, 4×10G SFP+ Uplinks, 90W Ports 1–4 | POEJK-S48-750E

Overview

The POEJK-S48-750E is a 48-port Gigabit PoE+/PoE++ edge switch with a 750W integrated PoE power supply, optimized for flexible, installer-friendly deployments at the convergent edge of the GRID ecosystem. It combines four high-power PoE++ ports, 44 PoE+ ports and simple front-panel toggles that let field techs enable VLAN isolation, extended-distance mode, watchdog and QoS without needing CLI access.

This switch is a workhorse for security, AV and remote-zone deployments where a few devices demand PoE++ (such as PTZ cameras or local PoE hubs) and many others only require PoE+. It is a natural fit for projects that blend Active POE-Jack® wall plates, long-run cameras, access points and other edge devices.

If you’re looking for a 48-port PoE switch with a few 90W ports and easy front-panel controls for use in Canadian warehouses, schools, retail sites or remote telecom rooms, the POEJK-S48-750E is designed for exactly that role.

Key features

• 48× PoE-capable access ports – 48 × 10/100/1000Base-T (RJ45) ports to support POE-Jack®, APs, cameras and other PoE endpoints.
• PoE++ on ports 1–4 – up to 90W per port (54VDC) on the first four ports for power-hungry loads such as multi-radio APs, PTZ cameras or downstream PoE hubs.
• PoE+ on ports 5–48 – up to 30W per port for IP surveillance, VoIP, access control, sensors and Active POE-Jack® nodes.
• 750W integrated PoE budget – built-in power sized for mixed PoE+/PoE++ deployments at the edge.
• Four 10G SFP+ uplinks – 4 × 10G SFP+ uplink ports for high-speed connectivity back to aggregation or core switches.
• Extended-distance mode – “Extend” function allowing ports 1–4 to reach up to 250 m over Cat5e/Cat6 (with throughput trade-offs depending on configuration).
• One-touch VLAN isolation – front-panel VLAN toggle that blocks inter-port traffic on ports 1–48, forwarding only to the uplinks for simple, secure segmentation.
• Automatic network watchdog – watchdog mode that reboots a port if it has link but no data for several minutes, helping restore frozen remote cameras or devices.
• QoS priority mode – QoS toggle that prioritizes labelled ports (marked on the front panel) for latency-sensitive traffic like APs, POE-Jack® or workstation links.
• Industrial-strength protection – 6kV surge protection and cUL listing for demanding commercial and security installations.

Ideal applications

• Security and surveillance networks mixing standard and high-power PTZ cameras.
• Remote IDFs or telecom rooms serving Active POE-Jack® wall plates plus local APs and sensors.
• Warehouse, manufacturing and logistics environments where extended cable runs are needed.
• Retail, hospitality and education projects needing simple VLAN and QoS toggles for non-specialist field techs.
• Edge PoE distribution for digital signage, small AV-over-IP islands and room booking/automation devices.

Compatibility & ecosystem

The POEJK-S48-750E is an excellent edge companion to GRID’s core (POEJK-S48-3600) and aggregation (POEJK-S48-740) switches. Use the four PoE++ ports for the few devices that truly require 90W—PTZ cameras, multi-radio APs or downstream PoE hubs—while using the PoE+ ports for Active POE-Jack® nodes, IP cameras, Wi-Fi, phones and other typical endpoints.

It integrates cleanly into GRID DC microgrid designs built on Cat6e/Cat6A permanent links and slim patch cords, extending PoE deeper into the building while keeping switching intelligence and simple diagnostics at the edge.

Install & design notes

Because this switch offers extended-distance mode on selected ports, designers should be aware of the associated throughput limitations and use it only where extra reach matters more than absolute bandwidth. The watchdog feature is particularly valuable in remote or hard-to-access areas (e.g., rooftop cameras on a Canadian warehouse), as it can automatically restore connectivity without a truck roll.

As with any mixed PoE+/PoE++ deployment, plan power budgets carefully: treat the four PoE++ ports as “heavy” loads and leave headroom in the 750W budget for future additions. Mount the switch in a well-ventilated rack or enclosure and consider surge protection and grounding best practices in areas prone to lightning or power quality issues.

Canada-ready checklist

• ✓ cUL listed for Canadian commercial and security applications.
• ✓ Extended-distance mode well suited to long camera runs in Canadian warehouses, yards and campuses.
• ✓ High-power ports support demanding PoE++ devices common in modern Canadian surveillance and Wi-Fi projects.
• ✓ Front-panel controls are useful for field techs in remote Canadian communities with limited on-site IT staff.
• ✓ Works with standard Cat5e/Cat6 cabling and accessories used throughout Canadian low-voltage installations.

Compatibility micro Q&A

Q: Do I have to use the extended-distance mode?
No. Extend mode is optional and only affects selected ports. For most runs, you’ll leave it off and operate at standard Ethernet distances and speeds.

Q: Can I manage this switch from a central NMS, or is it only front-panel?
The front-panel toggles are there for quick configuration in the field; you can still integrate the switch into your broader network management and monitoring tools as part of the GRID ecosystem.

Q: Is PoE++ available on all ports?
No. Full PoE++ up to 90W is supported on ports 1–4. Ports 5–48 support PoE+ up to 30W; plan your device placement accordingly.
