HPE P21106B21 Ethernet 1Gb 4-port Base-T I350-T4 network card

SKU CH-SFPB-P5KR0 MPN P21106B21

Four-port 1 Gb Base-T adapter using the Intel I350-T4 controller for HPE Gen10 Plus servers

  • Four 1 Gb ports expand server connectivity
  • Intel I350-T4 controller handles traffic efficiently
  • Offload engines reduce CPU load for I/O
  • Digitally signed firmware blocks rogue code installation
  • Designed for HPE Gen10 Plus server integration

Four-port 1 Gb server adapter

The HPE P21106B21 is a quad-port Ethernet adapter that provides four 1 Gb Base-T connections through a single PCIe slot. It is designed for HPE Gen10 Plus servers that need additional copper network links without occupying multiple expansion slots.

Suited for density-limited racks, not fibre builds

This card suits administrators who need to add several Gigabit copper ports to a compatible HPE server while conserving PCIe space. It does not serve environments that require SFP+ cages, 10 Gb or 25 Gb speeds, or fibre optic cabling.

Signed-firmware root-of-trust authentication

The adapter validates digitally signed firmware against a hardware root of trust before loading, blocking unauthorised or corrupted firmware images. This supply-chain protection is the decisive feature for deployments that mandate hardware-level firmware integrity.

Questions about this item

Will the four 1Gb ports on this P21106B21 adapter work with my existing Cat5e patch cables?

Yes, the Base-T interfaces are compatible with standard Cat5e cabling for 1Gb operation.

How can I confirm the I350-T4 controller is recognised and passing traffic after installation?

Check the OS network manager for four active 1Gb links and verify send/receive counters increment on each port.

Does the box include low-profile brackets for a 1U server, or must I order them separately?

The adapter ships with both full-height and low-profile brackets included.
