Vertiv ADX Rack Manager - ADX-RM1048PDAC-400

Vertiv ADX-RM1048PDAC-400 48-Port Managed PoE Rack Switch

Overview

The Vertiv ADX-RM1048PDAC-400 is a 1U rack-mounted managed switch with 48 RJ-45 Ethernet ports and Power over Ethernet support — built for structured rack environments where centralized network management and powered-device distribution need to share a single 1U slot. At 439.4 mm wide and just 43.7 mm tall (standard 1U), it fits any 19-inch EIA rack without modification, making it a practical fit for data center rows, telecom closets, or security head-end racks with constrained vertical space.

The ADX-RM1048PDAC-400 (often searched as ADX RM1048PDAC 400) is a managed-class device, meaning per-port configuration, VLANs, and traffic prioritization are on the table — important when you are mixing IP camera streams, VoIP endpoints, and access control readers on the same infrastructure and need QoS to prevent high-bandwidth video from crowding out time-sensitive control traffic.

Key Features

• 48 Managed RJ-45 Ports: A 48-port managed fabric in 1U gives you high port density without stacking multiple unmanaged units. Managed switching means you can segment traffic by VLAN, apply ACLs per port, and monitor link health — capabilities that matter in multi-tenant deployments or anywhere security and IT share the same physical rack.
• PoE Support: Onboard PoE eliminates the need for separate injectors on powered endpoints. IP cameras, wireless access points, and VoIP phones can draw power directly from the switch port, reducing cable runs and simplifying moves/adds/changes.
• 1U Rack-Mount Form Factor: At 43.7 mm tall and 439.4 mm wide, this unit occupies a single rack unit in any standard 19-inch cabinet. The 442 mm depth keeps it compatible with shallow-depth two-post racks as well as full-depth four-post enclosures.
• Centralized Management: As a managed switch, the ADX-RM1048PDAC-400 supports remote configuration and monitoring — reducing the need for on-site intervention when port settings, link status, or traffic policies need adjustment.

When This Is the Correct Choice

Deploy the ADX-RM1048PDAC-400 when you need a high-density 48-port managed PoE switch in a 1U footprint — particularly in rack-dense environments where vertical space is constrained and centralized traffic management is a requirement. It is well-suited to security head-end racks, IT closets, and structured cabling deployments where PoE endpoints and managed traffic separation are both on the requirement list.

When to Choose a Different Model

If your deployment requires fewer ports with a smaller physical footprint, consider a lower-port-count variant in the Vertiv ADX line. If you need unmanaged PoE switching for a simpler, lower-cost installation where per-port configuration is not required, a different product class is more appropriate.

Frequently Asked Questions

Q: How many RJ-45 ports does the ADX-RM1048PDAC-400 have?

A: The ADX-RM1048PDAC-400 has 48 RJ-45 Ethernet ports.

Q: Is the ADX-RM1048PDAC-400 a managed or unmanaged switch?

A: It is a managed switch, supporting per-port configuration, VLANs, and traffic management features.

Q: Does the ADX-RM1048PDAC-400 support Power over Ethernet?

A: Yes, the ADX-RM1048PDAC-400 includes PoE support, allowing it to power compatible endpoints directly from the switch ports.

Q: What rack form factor does the ADX-RM1048PDAC-400 use?

A: It is a 1U rack-mount unit with a width of 439.4 mm and depth of 442 mm, compatible with standard 19-inch EIA racks.

Q: Can the ADX-RM1048PDAC-400 be used in shallow-depth two-post racks?

A: At 442 mm depth, it is compatible with both two-post and four-post rack enclosures that accommodate that depth. Verify your rack's usable depth before ordering.

The ADX-RM1048PDAC-400 checks the boxes I care about most when specifying rack infrastructure for security and IT co-located environments: 48 managed ports in a single 1U slot, with PoE built in. That combination means you can provision an entire IP camera floor or access control segment from one unit without burning additional rack space on injectors or patch panels.

Technical Highlights:

• 48-Port Density in 1U: At 43.7 mm tall (1U), this switch delivers 48 managed RJ-45 ports — high density for the vertical real estate consumed. In a 42U rack, that ratio matters when head-end equipment, NVRs, and UPS units are all competing for space.
• Managed Switching: Managed-class hardware means you can enforce QoS policies that prioritize camera stream traffic, isolate VLAN segments for physical security from corporate IT, and get per-port diagnostics without a truck roll — operational advantages that compound over time in multi-camera deployments.
• PoE Integration: Built-in PoE removes the per-camera injector cost and the cabling complexity that comes with it. Fewer power bricks, fewer failure points, cleaner rack presentation.

Deployment Considerations:

• PoE budget per port and total switch PoE capacity are not specified in available documentation — confirm with Vertiv before sizing a deployment where camera count and PoE draw are tight. Oversubscribing a PoE budget is the most common commissioning error on managed PoE switches.
• At 442 mm depth, measure your rack's usable rear clearance before ordering. Some wall-mount and two-post racks in retrofit installations run shallower than the nominal spec.

The ADX-RM1048PDAC-400 is a practical choice for structured cabling deployments in purpose-built security operation centers or IT closets where a single managed PoE switch needs to serve 40+ IP endpoints without consuming more than one rack unit.
