HPE JL594A Flexfabric X721 Fan Tray

HPE JL594A FlexFabric X721 Front-to-Back Fan Tray

The HPE JL594A FlexFabric X721 Fan Tray is a replaceable cooling module for selected HPE FlexFabric network switches. It uses a front-to-back airflow design to move air from the switch port side towards the power supply side, helping maintain suitable operating temperatures.

Designed for supported enterprise switches, the X721 fan tray is useful when replacing a faulty cooling module or maintaining a consistent airflow configuration in a network rack.

HPE JL594A Technical Specifications

Front-to-Back Airflow for Network Switch Cooling

Airflow direction is one of the most important details when choosing a replacement switch fan.

The HPE JL594A draws air from the port side and moves it towards the power supply side. This helps maintain the cooling arrangement specified for compatible switch installations.

The X721 is different from the HPE JL595A X722, which uses the opposite airflow direction. These fan trays should not be treated as interchangeable simply because they have a similar appearance.

Compatible HPE FlexFabric Switches

HPE lists JL594A as a supported fan tray option for selected FlexFabric 5710 switches, including:

• HPE FlexFabric 5710 48SFP+ switch, JL585A.
• HPE FlexFabric 5710 48XGT switch, JL586A.
• HPE FlexFabric 5710 24SFP+ switch, JL587A.

Support may extend to other switch configurations. Always check the exact switch model, required airflow direction and HPE installation documentation before ordering.

When Should You Replace the Fan Tray?

A replacement may be needed if the switch reports a fan failure, the cooling module stops operating or the fan produces unusual mechanical noise.

Before replacing the unit, check the switch’s fan status and ensure that ventilation openings are not obstructed.

Use the relevant HPE installation guide to identify the faulty module and follow the correct replacement procedure. Avoid leaving a required fan tray slot empty for longer than the manufacturer permits.

New and Refurbished HPE JL594A

New Fan Tray

A New or unused HPE JL594A is suitable for planned switch maintenance or keeping a replacement cooling module available. Confirm the packaging, product condition and applicable warranty before purchasing.

Refurbished Fan Tray

A Refurbished X721 fan tray may be a cost-effective choice for maintaining existing network infrastructure.

For refurbished units, ask whether the fan has been inspected for connector damage, excessive noise and correct operation. Confirm the testing carried out and the warranty offered by the supplier.
