HPE JL295A Networking X240 25G 3m DAC Cable

HPE JL295A X240 25G SFP28 to SFP28 3m DAC Cable

The HPE JL295A Networking X240 is a 3-metre Direct Attach Copper (DAC) cable designed for 25Gb Ethernet connections between compatible networking devices. With an SFP28 connector at each end, it provides a convenient way to connect equipment within the same server rack or between nearby racks.

Unlike fibre optic connections that require separate transceiver modules, the JL295A uses an integrated copper cable assembly. This helps simplify short-distance network connections where supported HPE switches and other compatible devices are installed close together.

HPE JL295A Technical Specifications

Where Can You Use a 3m 25G DAC Cable?

A 3-metre DAC cable is useful when two network devices are positioned close together and a longer optical connection is unnecessary.

Typical applications include:

• Connecting compatible switches within a data centre rack.
• Linking supported servers and switches with qualified 25Gb SFP28 interfaces.
• Replacing damaged or missing 25Gb DAC cables.
• Supporting short-distance connections in high-bandwidth network environments.

The JL295A is intended for short cable runs. For longer distances, a supported optical transceiver and fibre cable or active optical cable may be more suitable.

Passive DAC vs Fibre Optic Cable

Both DAC and fibre optic connections can provide high-speed networking, but they are suited to different installation requirements.

The HPE JL295A uses copper conductors and integrated SFP28 connectors. There is no need to purchase separate optical transceivers for each end of the cable.

A fibre optic connection normally uses compatible transceivers and a separate fibre cable. It can be a better option when equipment is located farther apart.

For nearby devices, a passive DAC cable can provide a straightforward connection with fewer separate components.

HPE JL295A Switch Compatibility

HPE documents JL295A support for selected Comware-based networking products, including qualified HPE FlexFabric 5950 configurations.

For example, HPE compatibility documentation lists JL295A with the FlexFabric 5950 48SFP28 8QSFP28 switch (JH402A) and the FlexFabric 5950 24-port SFP28 module (JH450A), subject to supported software releases.

Before purchasing, check:

• The exact switch or network adapter model.
• Whether both interfaces support 25Gb Ethernet.
• Whether JL295A is listed as a supported cable.
• The required firmware or switch software release.
• The available distance and cable routing inside the rack.

Having an SFP28 socket does not automatically guarantee compatibility with every DAC cable.

Forward Error Correction and Link Configuration

HPE documentation identifies BASE-R, RS-FEC and no-FEC options for supported 1-metre and 3-metre X240 25Gb DAC connections.

Both interfaces on a link must use matching supported Forward Error Correction (FEC) settings.

If a newly installed cable does not establish a connection, check the switch compatibility list, port speed and FEC configuration before assuming that the cable is faulty.

New and Refurbished HPE JL295A

New HPE JL295A

A New or unused cable may be suitable for network expansion, equipment installation or keeping a spare available for maintenance. Confirm its condition and warranty before ordering.

Refurbished HPE JL295A

A Refurbished cable may be a cost-effective option for maintaining existing 25Gb network infrastructure. Buyers should confirm that the connectors have been inspected and the cable has been tested for reliable connectivity.

For both conditions, check stock availability, warranty coverage and UK delivery arrangements.
