HPE 649281-B21 QSFP Network Adapter

The HPE 649281-B21 is a network adapter that provides two QSFP ports for server connectivity. It is built for environments that require QSFP-based links in a single expansion slot. The adapter fits standard server architectures where this interface type is specified.

Suited for dual-QSFP uplinks.

This adapter suits administrators adding or replacing a dual-port QSFP connection in compatible HPE servers. It does not serve systems that require a different connector type, a different port count, or a form factor other than the one this card uses.

Dual QSFP connector configuration

The defining specification is the presence of two QSFP connectors on the adapter. Verify that the server slot and the intended cabling both match this dual QSFP layout before purchase.

Spørsmål om denne varen

What server slot is required to install the HPE 649281-B21 QSFP adapter?

The adapter uses a QSFP interface, so the host server must provide a compatible QSFP slot or cage for installation.

Can the 2 x QSFP ports on this adapter connect to legacy InfiniBand or Ethernet switches?

Each QSFP port accepts standard QSFP transceivers or direct-attach cables, allowing links to older switches that support matching QSFP modules and speeds.

How can I verify the HPE 649281-B21 is operating correctly after installation?

Check the server BIOS or operating-system network utility to confirm both QSFP ports appear as active adapters with valid link status.
