HP 2-Port Stacking Module for 2920 Switch Series

The HP J9733A is a two-port stacking module tailored for the HP 2920 Switch Series. It creates a high-speed link between switches, allowing several 2920 units to operate as one logical switch that you can manage from a single interface.

By moving inter-switch traffic onto dedicated stacking links, the module frees standard uplink ports and keeps latency low. Installation is straightforward: slide the module into the rear expansion slot of a 2920 switch, secure it, and attach the stacking cables. Because the unit has a design that is compact and lightweight, it fits neatly into crowded racks and is easy to handle during maintenance.

This capability is valuable for growing branch offices, campus networks, and small data centers where additional port density and resilience are needed but complexity must stay in check. Stacking multiple 2920 switches with the J9733A helps avoid spanning tree complications and reduces the number of management IP addresses you have to track.

The module relies on wired Ethernet technology, operates in temperatures from 0 to 45 degrees Celsius, and meets REACH and WEEE environmental standards. A limited lifetime warranty from HP provides long-term peace of mind.
