Product Identity

The HPE IB FDR 2P 545FLR-QSFP Adapter 702212-B21 is a QSFP network adapter designed for Hewlett Packard Enterprise server environments. It provides dual-port connectivity for high-performance InfiniBand fabrics in data centre deployments.

Sustained Operation

The adapter maintains consistent throughput across both QSFP ports during continuous data transfers. Its design supports the demanding bandwidth requirements of clustered compute and storage workloads without thermal throttling.

Installation Notes

The card installs into a compatible FlexibleLOM slot on supported HPE ProLiant servers. Verify the server generation and FlexibleLOM version before purchase; the adapter will not function in standard PCIe slots or non-HPE chassis.

Questions about this item

How much power does the 545FLR-QSFP adapter draw when running continuously?

The adapter uses a QSFP connector and is designed for FDR InfiniBand speeds; typical power draw for this class of card is in the low tens of watts.

What slot type must my server have to install the 702212-B21?

It requires an available PCIe slot that accepts a low-profile, half-height network adapter with a QSFP cage.

Will the 2-port QSFP adapter work with older QDR InfiniBand switches and cables?

Yes, FDR ports auto-negotiate down to QDR rates so existing QDR switches and copper or optical QSFP cables remain usable.
