8-Port 10GBase-T v2 zl Module

The HPE J9546A is an expansion module that adds eight RJ-45 ports for 10 Gigabit Ethernet connectivity. It is designed for data networking environments that require medium-distance links up to 100 metres over twisted-pair cabling. The module fits compatible HPE zl-series chassis to increase port density without transceivers.

Upgrading from 1 GbE uplinks

This module replaces slower copper uplinks or SFP+ configurations that need separate optics and patch cables. The jump is worthwhile when you can reuse existing Cat6a or Cat7 structured cabling for 10G speeds. It is not for networks that require fibre reach beyond 100 metres or densities higher than eight ports per slot.

Verify zl chassis compatibility

Confirm that your switch chassis accepts zl modules and has a free slot with sufficient backplane bandwidth. Check that your copper runs meet Cat6a or better specifications for the full 100 metre distance. Ensure the physical dimensions of 1.8 by 10.3 by 8.1 inches fit the chassis clearance.

Questions about this item

What chassis slot width does the 10.3-inch module require?

The module fits a standard zl expansion slot measuring 10.3 inches wide, 8.1 inches deep and 1.8 inches high.

Which step is often missed when seating the 8-port RJ-45 module in a live chassis?

Slide the module in until the ejector lever clicks, then tighten both captive screws to secure the electrical connection.

When should the Cat6a twisted-pair patch cords be replaced to keep 100-metre 10G links reliable?

Replace any cord that shows kinks, crushed jackets or failed certification tests; otherwise the module itself has no user-serviceable parts.
