IBM - 00Y3256 - Cisco Catalyst Switch Module 3110G

IBM 00Y3256 Cisco Catalyst Switch Module 3110G

The IBM 00Y3256 is a Cisco Catalyst Switch Module 3110G built to deliver integrated Gigabit Ethernet switching inside supported IBM blade chassis environments. As an enterprise access-layer module, it supports standard Layer 2 functions including VLAN segmentation, QoS traffic prioritisation, and security features for controlled network access within the chassis.

This switch module is designed for IBM BladeCenter platforms, making it a practical choice for maintenance, spares, or expanding existing blade deployments where consistent Catalyst-style management is required. It is commonly associated with IBM BladeCenter families such as BladeCenter H and BladeCenter T, depending on chassis and network design. For uplink design and fibre connectivity planning, it is often paired with compatible TRANSCEIVER options, subject to the interfaces and optics supported in your environment.

In larger BladeCenter builds, the 00Y3256 can be deployed alongside a chassis NETWORK MODULE to extend connectivity options, and it complements server-side I/O provided by a blade NETWORK ADAPTER for end-to-end Ethernet connectivity from host to uplink.

Key Features

Key specifications and deployment-relevant features for the IBM 00Y3256 Catalyst 3110G switch module:

• Cisco Catalyst 3110G switch module form factor to provide in-chassis Ethernet switching for supported IBM blade environments.
• Compatibility with IBM BladeCenter chassis families (for example BladeCenter H and BladeCenter T) to maintain a consistent switching footprint across existing installations.
• Gigabit Ethernet switching architecture to support typical blade workloads such as east-west server traffic and uplinks to aggregation.
• VLAN support to segment traffic between applications, tenants, or environments within a shared chassis.
• Quality of Service (QoS) capabilities to prioritise latency-sensitive flows such as voice, video, or critical application traffic.
• Enterprise security features to help control access at the edge and support policy-based network operations.
• Managed Catalyst operating model to align with standard enterprise monitoring, configuration, and change-control practices.
• Designed for continuous 24/7 operation to support data center and wiring-closet-style blade 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 IBM blade environments, reduce electronic waste, and control budgets compared to buying new.

All products include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include a three-month warranty). Extended warranty options are available on request. Direct Hardware Supply is an international supplier of refurbished IT hardware, shipping worldwide from Denmark, with a focus on reliable sourcing for enterprise infrastructure such as IBM platforms.
