Vertiv LV5500T-400 4K KVM Extender Transmitter

Overview

The Vertiv LV5500T-400 is the transmitter half of the Avocent Longview 5500 high-performance KVM extender system, purpose-built for environments where a workstation or server needs to be physically separated from its operator console — think broadcast control rooms, secure data center operations, industrial automation stations, or any facility where the compute hardware lives in a controlled environment but operators need full keyboard, video, and mouse control at a remote desk. This 1U rack-mountable transmitter unit connects at the source end, accepting local video and peripheral inputs and extending them across a structured cabling infrastructure to a paired receiver unit.

At 4096 x 2160 resolution support, the LV5500T-400 handles 4K content without downsampling — relevant for CAD, GIS, or video production workflows where pixel-accurate display fidelity is non-negotiable. Operators who have dealt with KVM extenders that silently degrade 4K signals to 1080p for transmission will recognize why this spec matters for professional environments.

Key Features

• 4096 x 2160 Maximum Resolution: True 4K graphic mode output means the remote operator sees the same pixel-accurate image the source workstation generates — critical in design, medical imaging, and broadcast environments where downsampled video introduces workflow errors or compliance issues.
• 1U Rack-Mountable Form Factor: At 1U, the LV5500T-400 slots cleanly into a standard equipment rack at the source end without consuming significant rack space — useful in dense rack environments where every unit of space is accounted for in the rack planning document.
• 18W Power Consumption: Drawing 18W from a 120V AC source, the transmitter's power footprint is modest enough that it won't meaningfully strain a standard rack PDU circuit. Plan for a dedicated outlet or factor it into your rack's per-circuit load budget alongside the compute gear it accompanies.
• Wide Input Voltage Range (100–240 VAC): The auto-ranging power input accommodates both North American and international facility voltages without an external transformer — useful for multi-site deployments or equipment that may be redeployed across global facilities.
• Wired Connectivity: Signal extension over structured cabling (rather than wireless RF) means deterministic latency and no interference from dense RF environments common in industrial or campus settings. This also keeps the video and KVM path within a physically auditable and securable infrastructure.
• Black 1U Enclosure: The rack-standard black finish at 2.84 lb keeps the unit light enough for a single technician to install without additional hardware support — relevant when commissioning multiple transmitter units across a large facility rollout.
• Compact Profile at 1.54" Height: The measured 1.54-inch height confirms standard 1U compliance, meaning it will fit in any 1U-capable rack bay without forced spacing adjustments.

Integration and Compatibility

The LV5500T-400 is the transmitter component of the Vertiv Avocent Longview 5500 KVM extender system and is designed to pair with the corresponding Longview 5500 receiver unit. Deployment requires both a transmitter (source end) and a receiver (console end) — purchasing only one unit will not produce a functional extension path. Verify that the paired receiver SKU matches your target resolution, distance, and cabling type requirements before ordering.

For facilities building out KVM extender infrastructure, the Longview 5500 family integrates into environments using structured Cat cabling or fiber, depending on the specific variant. Confirm your maximum extension distance and cabling plant type against the full Longview 5500 product family specifications to match the LV5500T-400 to the correct receiver and cabling tier.

Power delivery requires a standard AC outlet in the rack — the LV5500T-400 is not PoE-powered, so factor a PDU port or local outlet into your rack power planning. A well-structured rack PDU selection will ensure reliable power to both transmitter and the compute source in the same rack bay.

Frequently Asked Questions

Q: What is the maximum video resolution the LV5500T-400 supports?

A: The LV5500T-400 supports a maximum resolution of 4096 x 2160 (4K graphic mode), making it suitable for high-fidelity display environments such as broadcast, CAD, and medical imaging workflows.

Q: Does the LV5500T-400 include a receiver unit?

A: No. The LV5500T-400 is the transmitter unit only. A paired Longview 5500 receiver unit is required to complete the KVM extension path. Verify the correct receiver SKU for your cabling and distance requirements before ordering.

Q: What power supply does the LV5500T-400 require?

A: The LV5500T-400 operates on 100–240 VAC input and draws 18W. It connects to a standard AC outlet — it is not powered via PoE — so a PDU port in the rack is required.

Q: Is the LV5500T-400 rack-mountable?

A: Yes. The LV5500T-400 is a 1U rack-mountable unit, measuring 1.54 inches in height and weighing 2.84 lb, compatible with standard 19-inch equipment racks.

Q: What connectivity technology does the LV5500T-400 use?

A: The LV5500T-400 uses wired connectivity for signal extension, providing deterministic latency and a physically auditable signal path — preferable in secure or interference-dense environments over wireless alternatives.

Q: Can the LV5500T-400 be used internationally?

A: Yes. The auto-ranging input voltage (100–240 VAC) means it operates on both North American and international facility power without requiring a separate voltage converter.

The LV5500T-400 (also searched as LV5500T 400) is the source-end transmitter for Vertiv's Avocent Longview 5500 KVM extender platform — and that 4096 x 2160 resolution ceiling is the spec I'd focus on first when evaluating it for a deployment. Most budget KVM extenders advertise 4K support but silently downscale to 1080p for transmission; this unit's 4K graphic mode means the full pixel count actually travels the extension path to the paired receiver.

Technical Highlights:

• 4K Graphic Mode (4096 x 2160): Full 4K throughput without downsampling — the operator console displays exactly what the source workstation outputs, which matters for pixel-critical workflows like broadcast graphics or surgical imaging.
• 18W / 100–240 VAC Power: Modest 18W draw with auto-ranging input means one standard PDU port handles the transmitter regardless of facility voltage — no need to spec a dedicated circuit or voltage converter for international deployments.
• 1U Rack Form Factor at 2.84 lb: Light enough for single-technician installation in a standard rack bay without rail kits or additional hardware support, which accelerates deployment across multi-rack environments.

Deployment Considerations:

• The LV5500T-400 is the transmitter only — you must procure the matching Longview 5500 receiver separately. Confirm your required extension distance and cabling plant type (Cat vs. fiber) against the full Longview 5500 receiver lineup before placing an order, or you'll have a transmitter with no signal destination.
• Power comes from AC, not PoE — verify a PDU outlet is available in the rack where the transmitter installs. This is easy to overlook when the compute hardware in the same rack is already consuming most available PDU ports.

This unit fits best in broadcast control room and secure operations center buildouts where the compute rack must be physically separated from the operator floor — think server rooms with controlled access where every operator console sits in a different zone, and the 4K fidelity of the source workstation cannot be compromised in transit.
