Vertiv ADX-4YGLD-RM1048P 48-Port Rackmount Network Switch with Dual 1200W Power Supplies
Overview
The Vertiv ADX-4YGLD-RM1048P is a rackmount network switch built for high-density data center and enterprise edge environments where port count, power redundancy, and thermal resilience all matter. With 48 x 1G copper ports, four SFP+ uplinks, and dual 1200W power supplies in a single chassis, this switch targets deployments where a single PSU failure cannot be allowed to take down the fabric — think colocation rows, distribution-layer stacks, or infrastructure closets feeding dozens of endpoints simultaneously. The ADX-4YGLD-RM1048P (often searched as ADX 4YGLD RM1048P) ships factory-new from channel-direct sourcing, with no grey-market or parallel-import risk on a product where firmware provenance matters.

Key Features
- 48 x 1G Copper Ports: Enough capacity to serve a full rack of servers, IP cameras, or access-layer endpoints from a single switch — no stacking required for most medium-density deployments. Reducing the number of switches in a row cuts both cabling complexity and management overhead.
- 4 x SFP+ Uplinks: Dedicated 10G fiber uplinks keep your core-to-distribution bandwidth headroom wide, so the 48 downlink ports never compete with upstream traffic on a shared pipe. Useful when aggregating multiple ADX switches up to a core layer switch or a high-throughput firewall.
- Dual 1200W Power Supplies: Two fully redundant PSUs mean a single supply failure produces zero downtime — the surviving 1200W unit carries the full load. For environments running 24/7 operations (surveillance infrastructure, healthcare, financial trading floors), this is the spec that keeps a maintenance event from becoming an outage.
- 1 x USB Port + 1 x Console Port: Local console access via the dedicated console port simplifies initial provisioning without requiring a network connection — critical when commissioning a switch before the management VLAN is live. The USB port supports out-of-band firmware recovery or configuration bootstrapping.
- 1 x Management Port + 1 x RJ45 Serial Port: A dedicated out-of-band management interface isolates switch administration traffic from the production data plane. The RJ45 serial port supports legacy terminal access and integrates cleanly with serial console servers for remote hands operations.
- 3 Fans for Active Cooling: Three internal fans maintain airflow through the chassis across the full 0°C to 45°C (32°F to 113°F) operating range — covering most enclosed equipment rooms and open-air data halls without supplemental cooling. Fan redundancy reduces the risk of a single fan failure causing thermal shutdown mid-shift.
- Operating Temperature 0°C to 45°C: The ADX-4YGLD-RM1048P handles the thermal envelope of a standard server room or telco closet without derating. If your environment regularly exceeds 40°C ambient, plan airflow carefully — the upper bound here is standard, not extended-range.
- Storage Temperature -40°C to 70°C (-40°F to 158°F): Wide storage range means the unit survives transit and warehouse staging in cold climates or unconditioned loading docks without risk of component damage before installation.
- Operating Humidity 5% to 90% Non-Condensing: Covers typical data center and equipment room humidity ranges comfortably. Non-condensing is a standard qualification — if your environment experiences rapid temperature swings that could cause condensation, verify ambient controls before commissioning.
Integration and Compatibility
The four SFP+ ports make the ADX-4YGLD-RM1048P straightforward to integrate into existing fiber-uplink architectures. The dedicated management interface allows integration with out-of-band management platforms and network switching infrastructure without polluting in-band traffic. The RJ45 serial port connects directly to terminal servers for remote console access — a practical requirement in any managed colocation or NOC-driven environment.
For power continuity planning, pair this switch with compatible uninterruptible power supply systems upstream. The dual 1200W PSU design provides on-chassis redundancy, but upstream UPS protection remains a separate consideration for extended runtime during facility power events.
For teams deploying this switch in a surveillance-heavy infrastructure stack, review our PoE switch planning guide to assess whether PoE delivery is required at this layer or should be handled at the access edge. The ADX-4YGLD-RM1048P is a data-plane and management-layer switch — confirm PoE requirements against your access-layer design before finalizing the bill of materials.
Frequently Asked Questions
Q: Does the ADX-4YGLD-RM1048P support PoE on its 48 copper ports?
A: The available specifications for the ADX-4YGLD-RM1048P do not confirm PoE delivery on the 1G copper ports. If PoE is required at this layer, verify with Vertiv's product documentation before ordering — do not assume PoE capability from port count alone.
Q: What uplink speeds do the SFP+ ports support?
A: The ADX-4YGLD-RM1048P includes 4 x SFP+ interfaces. SFP+ is a 10G-capable form factor, making these ports suitable for 10G fiber uplinks to a core or aggregation switch — confirm specific transceiver compatibility with Vertiv's compatibility matrix.
Q: Is the dual PSU configuration hot-swappable?
A: The ADX-4YGLD-RM1048P ships with dual 1200W power supplies designed for redundancy. Whether the PSUs are hot-swappable (field-replaceable under load) should be confirmed against Vertiv's hardware maintenance guide for this model before planning a live-swap maintenance window.
Q: What is the operating temperature range of the ADX-4YGLD-RM1048P?
A: The unit operates from 0°C to 45°C (32°F to 113°F) and stores from -40°C to 70°C (-40°F to 158°F). This covers standard data center and equipment room environments; it is not rated for extended-temperature or outdoor-unconditioned deployments.
Q: How many management interfaces does the ADX-4YGLD-RM1048P provide?
A: The switch includes a dedicated out-of-band management port, a console port, a USB port, and an RJ45 serial port — four distinct access paths for provisioning, monitoring, and recovery operations.
Q: What certifications does the ADX-4YGLD-RM1048P carry?
A: Vertiv references agency approvals in the product data sheet for this model. Specific certifications (UL, FCC, CE, etc.) should be confirmed against the official Vertiv data sheet for the ADX-4YGLD-RM1048P before submitting for site compliance review.
The ADX-4YGLD-RM1048P is one of those switches I'd spec specifically for a distribution layer where PSU redundancy is non-negotiable. The dual 1200W supply configuration is the headline — each unit can independently carry the chassis load, so a PSU failure during a late-night maintenance window doesn't require an emergency call to restore uplinks. Combined with 48 x 1G downlinks and four SFP+ uplinks, this is a well-proportioned platform for high-density infrastructure rows.
Technical Highlights:
- Dual 1200W PSU: Each supply independently rated to carry the full chassis load — true N+1 redundancy at the power layer without requiring an external ATS or PDU-level switching.
- 4 x SFP+ Uplinks: Dedicated 10G uplink capacity keeps the 48-port access layer from becoming a bottleneck at the aggregation handoff — plan LAG bonding across at least two SFP+ ports for both throughput and link redundancy.
- Out-of-Band Management Port + RJ45 Serial: Two independent break-glass paths mean you can reach the switch even if the management VLAN is misconfigured or a routing loop isolates in-band access — a real operational safeguard in multi-tenant or co-managed environments.
Deployment Considerations:
- The 0°C to 45°C operating range is standard data center — if your equipment room runs warm (above 40°C ambient at the rack intake), add a thermal buffer via rack blanking panels before commissioning to keep the switch comfortably within spec.
- PoE capability on the 48 copper ports is not confirmed by available specs — if your design requires powered endpoints at this layer, validate against the full Vertiv data sheet before finalizing the BOM; assuming PoE at the distribution layer without verification is a common design mistake.
This switch is best positioned in the distribution layer of a medium-to-large enterprise campus or colocation environment — specifically where 48 ports of 1G access density, fiber uplinks to core, and on-chassis PSU redundancy need to land in a single rackmount unit without secondary redundancy appliances.
