Description

This is the hot-swappable fan module for the 5944 series data-centre top-of-rack switch (JL836A). It provides port-to-power, front-to-back airflow, suited to cold-aisle to hot-aisle deployments in enterprise aggregation, leaf and server-access layers. It serves as an initial or replacement fan tray for the switch.

The 5944 chassis has 5 fan tray slots, and fan trays are ordered separately for the switch. The module is powered by the host switch, so it has no separate power supply. The switch has a maximum draw of 233 W and requires at least one power supply. Variable-speed fans help reduce energy use, and hot-swappable trays support high availability.

This module is supported only on the 5944 48XGT 6QSFP28 switch (JL836A). It must be paired with front-to-back power supplies JL592A (450W AC) or JL688A (450W 48V DC). It cannot be mixed with JL838A Power-to-Port fan trays in the same chassis. The switch should not run with fewer than five fan trays for more than 24 hours.
