Dell VRTX Pass-Through Mezzanine Adapter

The Dell 3N9XX is a pass-through mezzanine network adapter built for Dell PowerEdge M520, M620 and M630 blade servers installed in a VRTX chassis. It provides a direct PCIe link from the blade to the chassis I/O module without any internal switching or logic. This design suits administrators who need deterministic low-latency paths to external physical switches.

Compatibility check before ordering

Verify that the target blade is a supported M520, M620 or M630 and that it resides inside a Dell PowerEdge VRTX shared infrastructure chassis. Confirm an available internal mezzanine slot on the blade and ensure the chassis I/O module provides the external switch connectivity your topology requires. The adapter will not function in non-VRTX enclosures or unsupported blade models.

What the bundle changes

The package contains only the 3N9XX pass-through mezzanine card itself. No cables, transceivers, drivers or management utilities are included, so you must source compatible SFP+ or other optics and any required firmware from the switch vendor or Dell support channels. Installation is a simple blade-slot insertion, but external cabling and switch configuration remain separate tasks.

Questions about this item

Does the Dell 3N9XX mezzanine card ship with any cables or transceivers, or must those be purchased separately?

The package contains only the pass-through mezzanine card; external I/O modules and any required cabling are supplied with the VRTX chassis, not with this adapter.

Which blade models are supported by the 3N9XX pass-through adapter?

The adapter is designed for PowerEdge M520, M620 and M630 blades installed in a VRTX chassis.

What does the 1Gbps or 10Gbps pass-through rating mean for actual throughput on the blade?

The card provides a direct PCIe lane to the chassis I/O module, so line-rate throughput matches whatever external switch module is installed in the VRTX.
