StarTech ST1000SPEX2 PCIe Gigabit Ethernet 1-Port NIC

Brand:

The StarTech.com ST1000SPEX2 is a 1-port PCI Express Gigabit Ethernet network card designed to add or replace a 10/100/1000Mbps RJ45 network interface in desktops, workstations and servers. Its PCIe x1 interface, 9K jumbo frame support, VLAN tagging, Wake-on-LAN, Auto MDIX and full-duplex operation make it suitable for enterprise connectivity upgrades, server networking, redundancy and network segmentation. Dual-profile brackets support installation across standard and small-form-factor systems.

OVERVIEW

  • The ST1000SPEX2 adds a 10/100/1000Mbps RJ45 Ethernet interface to PCIe-equipped desktops, workstations and servers, providing a cost-effective alternative to replacing an existing system for network expansion. Compatibility: PCIe x1 slot; compatible with 10/100/1000Mbps Ethernet networks. Compare: ST1000SPEX2 uses a Realtek RTL8111 chipset and dual-profile brackets; ST1000SPEXI uses Intel I210-AT and adds PXE support.

USE CASES

  • Desktop Gigabit network upgrade: Upgrades compatible systems from 10/100 Ethernet to Gigabit Ethernet without replacing the complete computer.
  • Server network expansion: Adds an Ethernet interface to a PCIe-enabled server for additional connectivity or network-interface replacement.
  • Network redundancy: Provides an additional physical network interface for supported server and workstation redundancy designs.
  • Network bridging: Adds a second network path for systems performing supported bridging or multi-network connectivity functions.
  • Legacy PC modernization: Extends the usable life of older systems by adding Gigabit networking where an appropriate PCIe slot is available.
  • Small-form-factor deployments: The included low-profile bracket supports installation in compatible compact chassis.
  • VLAN-enabled enterprise networks: Supports IEEE 802.1Q VLAN tagging for environments using logical network segmentation.
  • Large-file and storage transfers: 1Gbps Ethernet capability provides higher network throughput than legacy 10/100Mbps interfaces when the network infrastructure also supports Gigabit Ethernet.
  • Remote system management: Wake-on-LAN enables compatible systems to be remotely awakened for supported administration and maintenance workflows.
  • Network interface replacement: Provides a dedicated PCIe Ethernet interface when an onboard network port fails or requires replacement. 

KEY FEATURES

  • 10/100/1000Mbps Gigabit Ethernet: Supports multiple Ethernet speeds through auto-negotiation, allowing integration with existing network infrastructure while providing Gigabit capability where available.
  • PCI Express x1 interface: Uses a PCIe x1 expansion slot, providing a straightforward hardware path for adding Ethernet connectivity to compatible PCs and servers.
  • Single RJ45 port: Adds one dedicated copper Ethernet connection for network expansion, replacement or redundancy.
  • Up to 1000Mbps transfer rate: Provides Gigabit-class network performance for business data, file transfer and application connectivity.
  • Full-duplex operation: Allows simultaneous transmission and reception, supporting efficient bidirectional network communication.
  • 9K jumbo frame support: Allows larger Ethernet frames to reduce packet-processing overhead in compatible network environments.
  • IEEE 802.1Q VLAN tagging: Supports logical network segmentation for compatible managed-network deployments.
  • IEEE 802.1P Layer 2 priority encoding: Supports traffic prioritization mechanisms within compatible Ethernet environments.
  • IEEE 802.3x flow control: Helps manage traffic flow between connected network devices to support reliable data transmission.
  • Wake-on-LAN: Allows compatible systems to be remotely awakened over the network, supporting centralized IT management.
  • Auto MDIX: Automatically detects cable wiring requirements, simplifying connection to compatible Ethernet network equipment.
  • Dual-profile installation: Includes standard-profile and low-profile brackets, increasing chassis compatibility across conventional desktops, workstations and compact systems.
  • Link/activity and Gigabit indicators: Provides visual network status information to assist IT technicians with connection and troubleshooting checks.
