Crestron CEN-SWPOE-48-ULTRA – 48-Port Ultra PoE++ Managed Switch

Product Overview

The Crestron CEN-SWPOE-48-ULTRA is a 48-port managed PoE++ network switch designed for high-density commercial AV-over-IP deployments using Crestron DM NVX and DM NAX systems. It provides up to 90 W per port across 40 PoE++ Ethernet ports and includes eight 10 Gigabit SFP+ uplink ports for fiber backbone connectivity. With built-in AV-over-IP profiles and full Layer 2/Layer 3 management, this switch gives AV integrators and IT managers a single platform for network infrastructure and AV signal distribution.

Product Description

The CEN-SWPOE-48-ULTRA delivers PoE++ (802.3bt Type 4) power on 40 of its 48 Ethernet ports, supporting power-hungry AV endpoints such as 4K displays, digital signage players, wireless access points, and Crestron DM NVX devices from a single managed switch. Each PoE++ port delivers up to 90 W, with a combined maximum output of 2,880 W across all powered ports. Eight 10 Gigabit Base-X SFP+ ports accept multimode or single-mode fiber transceiver modules for uplink to a core network switch or fiber backbone.

The ULTRA designation indicates support for PoE++ (802.3bt Type 4), distinguishing this model from the standard CEN-SWPOE-48 which supports PoE+ (802.3at) only. This makes the CEN-SWPOE-48-ULTRA the appropriate choice when deploying endpoints that draw more than 30 W per port, such as certain pan-tilt-zoom cameras, multi-radio wireless access points, or high-power digital signage displays.

DM NVX and DM NAX profile selection automatically configures multicast management on the switch for Crestron AV-over-IP systems. The streamlined browser interface allows integrators to configure ports or assign AV profiles quickly, while the full CLI, SSH, SNMP, RADIUS, and TACACS+ management options satisfy IT department requirements. IGMP snooping, IEEE 1588 PTPv2, VLAN support, QoS, 802.1X, and DHCP snooping are all included. The 1U metal chassis mounts in standard 19-inch racks with reversible rack ears.

Key Features

• 40-Port PoE++ (802.3bt Type 4) — Delivers up to 90 W per port with a combined maximum output of 2,880 W across all PoE++ ports.
• 8x 10 Gigabit SFP+ Uplinks — Fiber uplink ports supporting multimode and single-mode transceivers for backbone connectivity.
• PoE++ vs. PoE+ Upgrade — Supports up to 3x the per-port power of standard PoE+ (802.3at), enabling high-draw AV and networking devices.
• DM NVX & DM NAX AV Profiles — Single-step profile selection configures multicast routing for Crestron AV-over-IP and Audio-over-IP deployments.
• Layer 2 & Layer 3 Management — Full routing, VLANs, IGMP snooping, PTP, QoS, static and dynamic routing, and DHCP server.
• AV-Optimized IGMP — Automated IGMP between switches with IGMPv3 and MLDv2 snooping for efficient multicast video distribution.
• Enterprise Security — 802.1X, DHCP snooping, dynamic ARP inspection, IP source guard, RADIUS, and TACACS+.
• Up to 16K MAC Addresses — Supports large-scale endpoint deployments across complex AV network topologies.
• 1U Rackmount Chassis — Metal, fan-cooled construction with reversible rack ears for flexible installation.

Typical Applications

• Large conference room and boardroom DM NVX AV-over-IP networks
• Auditorium and all-hands room AV distribution with high-draw endpoints
• Commercial multi-purpose room AV infrastructure
• Training room AV-over-IP deployments with mixed endpoint power requirements
• House of worship production networks with PTZ cameras and wireless APs
• Corporate campus AV distribution requiring high per-port PoE budgets

Frequently Asked Questions

What is the difference between the CEN-SWPOE-48-ULTRA and the CEN-SWPOE-48?

The ULTRA model supports PoE++ (802.3bt Type 4) delivering up to 90 W per port. The standard CEN-SWPOE-48 supports PoE+ (802.3at) delivering up to 30 W per port. Choose the ULTRA when deploying endpoints that require more than 30 W.

Do all 48 ports support PoE++?

No. Forty of the 48 ports provide PoE++. The remaining eight ports are 10 Gigabit SFP+ uplinks and do not supply PoE power.

What SFP+ transceivers are compatible?

The eight SFP+ ports support 10 Gigabit Base-X modules in both multimode and single-mode fiber. Transceivers such as the SFP-10G-SR are compatible. Modules are sold separately.

How does the DM NVX profile feature simplify deployment?

Selecting the DM NVX AV-over-IP profile in the switch's web interface automatically applies the multicast management configuration required by DM NVX encoders and decoders, eliminating manual IGMP and VLAN setup.

Does this switch require any additional Crestron controllers?

No. The switch operates independently and is managed via its built-in web interface or IT management tools. Integration with a Crestron control system is optional for automated switching behavior.

What warranty applies?

Covered under Crestron's standard limited warranty. Full warranty details are available at crestron.com/warranty.
