HPE 652497-B21 dual-port gigabit Ethernet adapter low-profile PCIe card

HPE

HPE 652497-B21 Ethernet 1Gb 2-port 361T network card

SKU CH-RFP9-2XS74

Dual-port gigabit Ethernet adapter using an Intel I350 controller on a PCIe 2.1 x4 interface

  • Dual-port Gigabit Ethernet frees a second I/O slot
  • PCI Express Gen 2.1 x4 link delivers full bandwidth to both ports
  • Intel I350 controller handles segmentation and large-send offload
  • Wake-on-LAN and PXE enable remote boot and management
  • Jumbo Frames plus fault tolerance and load balancing boost throughput

HPE 652497-B21 dual-port Gigabit adapter

This PCI Express Gen 2.1 x4 network card adds two copper 1Gb Ethernet ports to HPE ProLiant servers. It is built on the Intel Ethernet Controller I350 and ships ready for standard or low-profile slots. Wake-on-LAN and PXE support are included for remote management and network boot scenarios.

Suited for ProLiant owners adding copper links

The card targets administrators who need two gigabit connections on a single x4 slot without using fibre. It does not serve environments that require speeds above 1Gb per port or fibre-based media. Teams needing additional ports beyond two should evaluate other options.

PCIe Gen 2.1 x4 interface decides fit

The adapter requires a four-lane PCI Express Gen 2.1 slot to operate at its designed bandwidth. Verifying that the server provides this exact slot type is the single check that determines whether the 652497-B21 can be installed.

Questions about this item

Will the Intel I350 controller on this 361T adapter need a firmware update after installation?

The adapter ships with the Intel I350 controller and supports PXE boot; firmware updates are available from HPE if a specific issue arises.

Does the PCIe 2.1 x4 link become the throughput ceiling when both 1 Gb ports run at line rate?

The four-lane PCIe 2.1 interface provides more than enough bandwidth for dual 1 Gb traffic, so the ports reach line rate before the bus saturates.

How much heat does the card add to a server running 24/7 with both copper ports active?

As a low-profile PCIe card without an onboard fan, it relies on chassis airflow and adds only modest heat typical of a dual-port 1 Gb NIC.
