Description

The Nexus 2348TQ Fabric Extender brings 48x 10GBASE-T server-facing ports together with six QSFP+ fabric uplinks to extend a parent Nexus switch into the rack with a single point of management. This 1RU, dual-PSU, hot-swap design supports front-to-back or reverse airflow and QSFP+ 40G or 4x10G breakout on supported parents. This bundle includes 4x Fabric Extender Transceivers (FET) for short-reach fabric connections to the parent.

Features

- 48-port 10GBASE-T host connectivity for dense rack-scale server aggregation
- Six QSFP+ fabric uplinks for high-bandwidth connectivity to parent Nexus switches
- Includes 4x FET optics for cost-effective, short-reach fabric links
- Single point of management through the parent; no local switching complexity
- Flexible fabric options: 40G or 4x10G breakout per QSFP+ (where supported)
- Redundant, hot-swappable PSUs and fans with selectable airflow
- Ideal for top-of-rack deployments in data center fabrics
- License-free hardware; leverage features licensed on the parent

FAQs

Q: What parent switches are compatible?
A: Nexus 5K/6K/7K/9K models that support FEX with appropriate NX-OS versions. Verify release notes for specific compatibility.

Q: Does this unit provide PoE on the RJ45 ports?
A: No. The 10GBASE-T host ports are non-PoE.

Q: How many fabric uplinks do I need to use?
A: You can use 1 to 6 QSFP+ uplinks. For resilience and bandwidth, deploy two or more in a fabric port channel.

Q: Can the QSFP+ uplinks be split into 4x10G?
A: Yes, on supported parents and optics, QSFP+ ports can be channelized into 4x10G using breakout cables or optics.

Q: Is any license required on the FEX itself?
A: No. The FEX is license-free; features and licenses apply on the parent Nexus.

Q: What airflow options are available?
A: Both port-side intake and port-side exhaust configurations are available. Ensure fans and PSUs match the desired airflow direction.

Q: What is included in this 4F bundle?
A: It includes 4 x Fabric Extender Transceivers (FET) for the fabric uplinks, along with 2 PSUs and 3 fan modules.
