Vertiv ADX-2YGLD-RM1048P 48-Port Managed Rack Switch with Dual 1200W PSUs

The Vertiv ADX-2YGLD-RM1048P is a 48-port 1G managed rack switch purpose-built for high-density data center and enterprise edge deployments where uptime, redundant power, and 10G uplink density matter. With four SFP+ uplink ports, a dedicated out-of-band management interface, and dual hot-swap 1200W power supplies, this switch is engineered for environments where a single PSU failure cannot be a service event. Part of the Vertiv Avocent ADX infrastructure management line, the ADX-2YGLD-RM1048P (often searched as ADX 2YGLD RM1048P) targets colocation rows, server closets, and enterprise access layers where a clean, supportable platform is required.

Overview

The ADX-2YGLD-RM1048P addresses a common data center challenge: you need dense 1G device connectivity with reliable 10G uplinks to your core, redundant power for five-nines availability, and out-of-band management so you can reach the switch even when the in-band network is down. Three onboard fans provide active cooling to handle the thermal load of 48 active ports and dual 1200W power supplies — critical in tight rack deployments where passive airflow is insufficient. For teams building or expanding managed network switch infrastructure, this platform delivers a predictable, rack-native footprint.

Port Configuration and Throughput

• 48 x 1G Access Ports: Full 48-port 1G density in a single rack unit means you can terminate an entire server row or a full patch panel run without cascading to a second switch — keeping your rack topology flat and your latency predictable.
• 4 x SFP+ Uplink Ports: Four 10G SFP+ uplinks give you dedicated high-bandwidth paths to your core or distribution layer. Using all four lets you aggregate uplinks for redundancy or distribute traffic across multiple upstream devices without oversubscribing the uplink tier.
• 1 x Console Port: The dedicated RJ45 serial console port means initial configuration and emergency recovery don't depend on in-band connectivity — essential during commissioning or when a misconfiguration locks out IP access.
• 1 x USB Port: The onboard USB port supports config file backup, firmware staging, and recovery — standard practice for large switch deployments where consistent firmware baselines need to be pushed without a TFTP server in scope.
• 1 x Management Port: The dedicated out-of-band management Ethernet port isolates switch control traffic from production data paths, a non-negotiable requirement for any enterprise network infrastructure environment following management-plane separation best practices.

Power and Redundancy

• Dual 1200W Hot-Swap PSUs: Two independent 1200W power supplies in active-active or active-standby configuration mean a PSU failure during a production window does not require a maintenance event. For 24/7 data center operations, this is the baseline redundancy requirement — a single-PSU switch should never anchor a critical access layer.
• Dual Power Input Design: Connecting each PSU to a separate power distribution unit (PDU) or UPS feed provides full A/B power path redundancy. If your facility feeds dual power rails to racks, this switch is wired to exploit that architecture without any additional hardware.
• 3 Onboard Fans: Three active cooling fans maintain airflow across the switch chassis under full port load. In dense rack environments where temperatures creep at 40–45°C ambient, active cooling with redundant airflow paths is essential for sustained reliability.

Environmental Ratings

• Operating Temperature 0°C to 45°C (32°F to 113°F): Covers standard data center and enterprise wiring closet environments. Note the upper bound of 45°C — if your rack ambient consistently approaches this, verify airflow management before deploying without supplemental cooling.
• Operating Humidity 5% to 90% Non-Condensing: The wide non-condensing humidity range accommodates most controlled environments, from dry raised-floor data centers to more variable wiring closet installations in commercial buildings.
• Storage Temperature -40°C to 70°C (-40°F to 158°F): Extended storage range allows safe staging in warehouse or loading dock environments before final rack installation — practical for large-scale rollouts where hardware ships before the data center space is ready.

Installation Notes

The ADX-2YGLD-RM1048P is rack-mounted (RM designation indicates rack mount form factor) and fits standard 19-inch EIA cabinets. The RJ45 serial console port is your first point of contact during initial provisioning — have a terminal emulator and a rollover cable ready before racking. Connect each of the two PSUs to independent power feeds from day one; a single-feed install defeats the redundancy architecture. Review agency approvals in the Vertiv product datasheet for your specific compliance requirements, as approval listings can vary by destination market. For PoE switch planning needs across the same deployment, note this platform is a non-PoE switch — PoE delivery requires a separate PoE-capable access layer or midspans if powering IP endpoints from this switch is a requirement.

Frequently Asked Questions

Q: Does the ADX-2YGLD-RM1048P support PoE or PoE+ power delivery on its 48 access ports?

A: No. Based on available specifications, the ADX-2YGLD-RM1048P does not provide PoE or PoE+ power delivery. If you need to power IP cameras, VoIP phones, or access control readers from the switch, you will need a PoE-capable switch or external midspan injectors.

Q: How many SFP+ uplink ports does the ADX-2YGLD-RM1048P have?

A: The ADX-2YGLD-RM1048P includes 4 x SFP+ uplink ports for 10G connectivity to your core or distribution layer, alongside 48 x 1G access ports for device termination.

Q: What happens if one power supply fails on the ADX-2YGLD-RM1048P?

A: The ADX-2YGLD-RM1048P ships with dual 1200W power supplies designed for redundancy. If one PSU fails, the second maintains full switch operation. For true A/B redundancy, connect each PSU to a separate power feed or UPS.

Q: What is the operating temperature range of the ADX-2YGLD-RM1048P?

A: The ADX-2YGLD-RM1048P operates between 0°C and 45°C (32°F to 113°F) and stores between -40°C and 70°C (-40°F to 158°F). Operating humidity is 5% to 90% non-condensing.

Q: Does the ADX-2YGLD-RM1048P have an out-of-band management port?

A: Yes. The ADX-2YGLD-RM1048P includes a dedicated management port that separates control-plane traffic from production data traffic, along with a console (RJ45 serial) port for direct CLI access independent of any IP connectivity.

Q: What rack form factor does the ADX-2YGLD-RM1048P use?

A: The ADX-2YGLD-RM1048P carries an RM (rack mount) designation and is designed for standard 19-inch EIA rack cabinets. Exact rack unit height should be confirmed against the Vertiv product datasheet for your rack space planning.

The ADX-2YGLD-RM1048P is the switch I reach for when a customer needs 48-port 1G access density and the dual-PSU requirement is non-negotiable. The two 1200W power supplies aren't just a checkbox — in a row deployment where you're running 40+ active ports continuously, having A/B power paths from separate PDUs means your next PSU swap is a scheduled event, not a 2am emergency. This platform fits squarely in the enterprise access layer and colocation edge where availability targets drive the spec sheet.

Technical Highlights:

• Dual 1200W PSUs: Each PSU is independently rated at 1200W — sufficient headroom for full 48-port line rate plus 4x SFP+ uplinks without either supply running near its limit under normal load. Connect to separate PDU feeds on day one.
• 4 x SFP+ Uplinks: Four dedicated 10G uplink ports let you deploy link aggregation (LACP) to your distribution layer or spread uplinks across multiple upstream switches for path diversity — without touching your 48 access ports.
• Out-of-Band Management Port: The dedicated management interface means you can reach and reconfigure this switch over a separate management network even if the data-plane is saturated or misconfigured. This is the port that saves you a truck roll at 11pm.

Deployment Considerations:

• The operating temperature ceiling is 45°C — verify that your rack's hot aisle temperature stays comfortably below this under peak load, especially in partially populated or high-density rows where airflow management is imperfect.
• This is not a PoE switch. If your access layer needs to power IP cameras, APs, or VoIP handsets, plan a parallel PoE-capable access tier or budget for midspan injectors — don't assume the 1200W PSUs translate to PoE budget.

For colocation operators provisioning server rows or enterprise IT teams building out a high-availability access layer in a controlled data center environment, the ADX-2YGLD-RM1048P delivers the right combination of port density, redundant power, and out-of-band control — without requiring a purpose-built chassis platform.
