HP J9988a 24-port Gigabit Ethernet module

The HP J9988a is a plug-in expansion module that adds twenty-four Gigabit Ethernet ports to compatible chassis. It targets network administrators who need high-density copper connectivity in a single slot. The module delivers 1000Mbps throughput per port for server aggregation or access-layer deployment. Buyers who require Power over Ethernet or SFP uplinks should evaluate other modules.

Passive cooling and low power draw

As a plug-in module it relies on the host chassis fans for airflow, adding no independent noise source. Power consumption scales with active link count and stays within the chassis power budget. The 2.2Lbs weight reflects a dense PCB without heavy heatsinks. Installers must verify that the chassis thermal design supports full 24-port line-rate traffic.

No bundled software or accessories

The package contains only the module itself; no transceivers, cables or management licences are included. Configuration is handled through the host switch operating system already present in the chassis. Administrators needing advanced Layer 3 features must licence them on the host platform separately. The GTIN 0888182604267 assists asset tracking in procurement systems.

Questions about this item

How do I install the J9988a plug-in module in a compatible HP chassis?

Power off the chassis, align the module with an available expansion slot, and press firmly until the latch clicks. The step most people miss is securing the retention screw after the latch engages.

What maintenance will the 24-port Gigabit Ethernet module need over time?

Keep the chassis air filters clean so airflow reaches the module. No user-serviceable parts exist inside; if a port fails the whole module is replaced.

What limit appears first when all 24 ports run at 1000 Mbps continuously?

The chassis power budget and thermal capacity are reached before the module’s own 1 Gbps per-port ceiling.
