This artical hardware matching guide introduces 2930F JL254A switch hardware specs, supported SFP+/SFP transceivers, DAC cable restrictions, fiber‑cable requirements, common compatibility pitfalls and ETU‑LINK replacement‑SKU reference for enterprise network engineers and system integrators deploying access‑layer networks.

In order to be more widely compatible with more branded devices, ETU-Link has newly introduced the Aruba 2930F JL254A switch, 2930F supports built-in 1GbE or 10GbE uplink, PoE+, access OSPF routing, tunnel node, RIP routing and IPv6, no software license required.The Aruba 2930F switch series provides a convenient and cost-effective access switch solution that can be set up quickly with zero-touch configuration and built-in 10GbE uplinks. The Aruba 2930F JL254A switch features 48 RJ-45 auto-sensing 10/100/1000 ports and 4 SFP+ 1/10GbE ports.

Below, ETU-LINK will list the optical modules that can be configured with the Aruba 2930F JL254A switch.

What DAC Direct Attach Copper Cables Are Supported / Unsupported On JL254A?

Aruba 2930F JL254A switch can use DAC cables in addition to optical modules, including 10G SFP+ to SFP+ 1m direct copper cable (J9281D) and 10G SFP+ to SFP+ 3m direct copper cable (J9283D). It should be noted that the 2930F series switches do not support the use of 10G LRM (J9152D), nor the use of 7M 10G DAC (J9285D).

The above is the optical module matching scheme of the Aruba 2930F JL254A switch. For more information, please refer to previous blogs.
