HPE - 451357-001 - Cisco Catalyst 1/10GbE 3120X Blade Switch

The HPE 451357-001 (Cisco Catalyst 3120X) is a blade switch module designed to deliver integrated 1/10GbE switching inside a blade enclosure. It provides high-speed internal connectivity for blade servers and supports typical enterprise switching functions such as VLAN segmentation, QoS traffic prioritisation, and network access controls—useful when you need predictable performance for virtualised workloads and east-west traffic.

This module is commonly deployed in HPE blade environments and is compatible with HPE BladeSystem c-Class enclosures, including examples such as the c7000 and c3000, where it can be used to build redundant fabrics and simplify cabling. For broader infrastructure planning within the same vendor ecosystem, you can also browse related HPE hardware categories.

For fibre uplinks and mixed-media designs, this switch is typically paired with appropriate optics from the TRANSCEIVER category. In environments where blades connect to external servers or appliances, complementary host connectivity options from NETWORK ADAPTER can help align end-to-end link speeds and media types.

Key Features

Key technical characteristics of the Catalyst 3120X blade switch module for HPE blade infrastructures:

• Blade switch module form factor for HPE BladeSystem c-Class enclosures, to provide integrated switching without a separate top-of-rack access switch.
• 1/10GbE switching capability (model family feature), to support bandwidth-intensive blade server traffic and virtualisation uplinks.
• VLAN support, to segment tenant, application, or management networks within the blade chassis.
• Quality of Service (QoS) features, to prioritise latency-sensitive services such as voice, VDI, or storage-related traffic.
• Enterprise switching security controls (family-typical), to help enforce port/network access policies and reduce lateral movement risk.
• Designed for compatibility with HPE BladeSystem c-Class (e.g., c7000 and c3000) with Cisco Catalyst 3120X switching, to maintain consistent chassis networking across existing deployments.
• Support for standard uplink design patterns (copper/fibre depending on configuration), to integrate blade networks into aggregation/core layers.
• Enterprise-grade hardware intended for 24/7 operation, to support continuous service delivery in data centre and edge chassis deployments.

Refurbished Quality and Warranty

This unit is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished switching modules are a practical way to extend the lifecycle of installed blade infrastructures, reduce electronic waste, and control budgets compared to buying new.

All standard refurbished products from Direct Hardware Supply include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries: three-month warranty). Extended warranty options are available on request, and we ship worldwide from Denmark for international B2B projects.

When integrating blade switching into a wider network, upstream connectivity is often terminated on an edge or WAN device such as a ROUTER depending on your topology and segmentation requirements.
