ThinkSystem 4-Port Gigabit Adapter

The Lenovo ThinkSystem Broadcom NetXtreme PCIe 1Gb 4-Port RJ45 Ethernet Adapter adds four 1000Base-T connections to a compatible server. It installs in a PCI Express 2.0 x4 slot and is designed for ThinkSystem and System x platforms needing extra wired network links.

Four RJ45 ports on one card

Four twisted-pair ports let you aggregate bandwidth, isolate traffic or connect separate networks without occupying multiple expansion slots. The single-card design reduces cabling complexity and keeps the server chassis tidy.

Verify slot height and bracket fit

The low-profile dimensions of 0.75 by 5.20 by 2.72 inches require a matching bracket and sufficient clearance in the target chassis. Confirm the server has an available PCIe 2.0 x4 slot and that the operating system supports the Broadcom NetXtreme driver stack.

Questions about this item

Will the four RJ45 ports on this 7ZT7A00484 adapter need any firmware updates or transceiver replacements over time?

The adapter uses fixed copper RJ45 ports with no pluggable transceivers, so no transceiver swaps are required; firmware updates are handled through the host server management tools when Lenovo releases them.

What throughput ceiling appears first when all four 1000Base-T links run at full load on the PCIe 2.0 x4 interface?

Four simultaneous 1 Gbps links can saturate the PCIe 2.0 x4 bus, so the host bus becomes the limiting factor before the individual ports reach their rated speed.

How much heat does the card add to a server chassis when it operates continuously at 10000 megabits_per_second across all ports?

The low-profile plug-in card draws modest power typical for a four-port 1 GbE adapter, adding minimal heat that standard server airflow handles without extra cooling.
