QFX5100 Ethernet Switches

A Juniper switch connects and manages traffic between servers, storage, network devices and other endpoints. QFX5100 Ethernet Switches are used in data centre spine-and-leaf architectures, top-of-rack deployments, virtual chassis environments and enterprise or service provider networks. Model selection typically considers port type, port density, uplinks, power supply, airflow and installation requirements.

QFX5100 configurations include 24 or 48 SFP+/SFP ports, with QSFP+ uplink and expansion options depending on the model. The Juniper QFX5100-48S-3AFI provides 48 SFP+/SFP ports and 6 QSFP+ ports. Other QFX5100 Switches may offer SFP+, QSFP+ and Base-T options, so confirm the exact product identifier before ordering.

Yes. QFX5100 Ethernet Switches are listed for data centre spine-and-leaf network architecture and can also support top-of-rack and virtual chassis deployments. Their suitability depends on the required port types, uplink design, airflow direction, power arrangement and compatibility with the wider network. Terabit Systems offers solution configuration assistance for selecting an appropriate model.

QFX5100 Switches are available with AC or DC power options depending on the model, and redundant power supplies are available for supported configurations. The QFX5100-48S-3AFI includes two AC power supplies. Buyers should verify the exact power configuration, input requirements and redundancy arrangement for the specific unit being quoted.

QFX5100 Switches are available with front-to-back airflow, identified as AFO, or back-to-front airflow, identified as AFI, depending on the configuration. The QFX5100-48S-3AFI uses back-to-front airflow for standard data centre hot-and-cold-aisle arrangements. Confirm airflow direction against cabinet layout and adjacent equipment before purchasing.
