Purpose and audience

This HP JH185A fan tray is a replacement cooling module for the HP FlexFabric 5930 4-slot switch. It fits network operators who need to maintain proper airflow direction in an existing chassis.

Upgrade context

The tray replaces a failed or missing unit to restore the designed back-to-front air path. The jump is worth it when the switch shows thermal alarms or when a slot is empty and the airflow balance is broken.

Practical limits

The tray uses two fans to push air from the power side toward the port side across a 3.4 by 8.2 inch footprint. It weighs approximately 2.01 lb and carries REACH environmental certification.

Questions about this item

What are the exact dimensions of the HP JH185A fan tray so I can confirm it fits my 5930 4-slot switch?

The tray measures 3.4 inches high, 3.4 inches wide and 8.2 inches deep, matching the 5930 4-slot chassis slot exactly.

Which direction must the airflow run when I slide the JH185A into the switch?

Air must flow from the power side at the rear toward the port side at the front; install the tray so the label faces the ports to achieve this back-to-front pattern.

How many fans are inside the tray and when should I plan to replace them?

The tray contains two fans; expect to replace the entire tray after several years of continuous operation when bearing noise or reduced airflow appears.
