24-port 10/100/1000 BASE-T module

This HPE J9550A module adds 24 copper Ethernet ports to a compatible zL series chassis. It delivers 10, 100 and 1000 Mbps connectivity over standard twisted-pair cabling. The unit is designed for rack-mounted server environments requiring high-density 1GbE access. It ships new with firmware updated and components tested.

Upgrade from older 10/100 line cards

Replacing legacy 10/100 modules with this 10/100/1000 version raises the per-port ceiling to gigabit speeds without changing cabling infrastructure. The jump is worth it when servers or workstations need consistent 1000 Mbps throughput for backup, imaging or file services. Compatibility is limited to zL series chassis identified as CAT-12889. The module is not hot-swappable, so installation requires a planned maintenance window.

Sustained load behaviour

Under continuous multi-port traffic the module maintains line-rate forwarding across all 24 ports without oversubscription. Because it lacks hot-swap capability, the chassis must be powered down for insertion or removal, eliminating live migration scenarios. Thermal performance scales with chassis airflow design rather than an independent cooling solution. Firmware updates applied before shipment ensure current stability fixes are active.

Questions about this item

What chassis slot size does the J9550A module require?

The J9550A is a zL-series module designed for a single slot in a compatible zL chassis such as the CAT-12889.

What power state must the chassis be in before inserting the J9550A?

Because the module is not hot-swappable, the chassis must be powered off before the J9550A is inserted.

Which component would need replacement if a 10/100/1000 BASE-T port stops working?

The entire J9550A module would need to be replaced since individual ports are not field-replaceable.
