Eaton SPK040 – Gigabit Network Module for Rack PDU G4

Product Overview

The Eaton SPK040 is a gigabit network module — not a standalone PDU — used to add or upgrade network monitoring and remote management capability on Eaton's Rack PDU G4 platform. This hot-swappable network interface module is the correct choice for IT teams that already own a compatible managed or switched Eaton rack PDU and need to add gigabit network connectivity, SNMP monitoring, or replace an aging G3-generation card. Data center and server room operators searching for a rack PDU network management card, PDU network module upgrade, or gigabit network card for Eaton PDU will find this the direct fit for G4-series units.

Product Description

The SPK040 slots into the network module bay of a compatible Eaton Rack PDU G4 unit, giving the PDU a gigabit-capable Ethernet connection for remote monitoring, alerting, and outlet-level management through Eaton's Brightlayer power management software. It is commonly deployed as an upgrade path when replacing an older-generation eNMC (G3) network card with the newer GNM (G4) module, restoring or extending remote monitoring on PDUs already installed in a rack. Reference the product photo to confirm the card's physical connector layout before ordering, and always match the module to the PDU model's supported network card generation, since G3 and G4 cards are not universally interchangeable. Because it is a communication accessory rather than a power distribution device, the SPK040 does not carry outlets, receptacles, or a load rating of its own — its role is purely to give an Eaton managed or switched rack PDU a network presence for SNMP polling, HTTPS/HTML5 dashboard access, and integration with data center infrastructure management (DCIM) tools. Integrators standardizing PDU fleets on a common network management layer, or those needing to bring an existing PDU up to current firmware and security standards, should treat the SPK040 as the network upgrade component rather than a replacement for the PDU itself.

Key Features

• Gigabit Ethernet Connectivity — Adds network-based remote monitoring and management to compatible Eaton rack PDUs.
• Hot-Swappable Design — Can be installed or replaced without powering down the connected PDU or its load.
• G4 Platform Compatibility — Purpose-built for Eaton's Rack PDU G4 series, including as a documented replacement for older G3 eNMC cards.
• Brightlayer / SNMP Integration — Supports remote monitoring through Eaton's Brightlayer power software and standard SNMP tools.
• UL 2900-1 Cybersecurity Certification — Meets recognized network device security standards for IT environments.
• Compact Accessory Footprint — Small form factor designed to fit the PDU's dedicated network module bay without added rack space.
