Questions & Answers
What is the HPE 813874-B21 10GBase-T SFP+ Transceiver?
The HPE 813874-B21 is a hot-pluggable 10GBase-T SFP+ copper transceiver module for 10 Gbps Ethernet over RJ45 cabling. It delivers reliable connectivity up to 30 meters on Cat6a/Cat7 cables.
Which devices are compatible with the HPE 10GBase-T SFP+ Transceiver?
This transceiver is officially supported in HPE switches, routers and servers with standard SFP+ ports, including Aruba CX, FlexFabric and ProLiant platforms. Third-party IEEE 802.3an-compliant systems may operate it but lack HPE validation.
What types of cables does the HPE 813874-B21 support?
It supports Category 6a and Category 7 twisted-pair copper cables terminated with RJ45 connectors. For optimal performance at 10 Gbps, use shielded Cat6a or Cat7 cabling.
How far can the HPE 10GBase-T SFP+ Transceiver transmit data?
It supports distances up to 30 meters on Cat6a and up to 45 meters on Cat7 cabling. Link reach may vary with cable quality and environmental conditions.
Is the HPE 813874-B21 transceiver hot-pluggable?
Yes. You can install or remove the 10GBase-T SFP+ transceiver without powering down the host device.
Does this transceiver support Auto MDI/MDI-X?
Yes. Auto MDI/MDI-X is supported for automatic crossover detection and correction over copper links.
What is the power consumption of the HPE 10GBase-T SFP+ module?
Typical power consumption is 2.5 watts per module under normal operating conditions. Actual power draw may vary by temperature and link activity.
Can I use third-party copper cables with the HPE 813874-B21?
Yes, IEEE 802.3an-compliant Category 6a or higher cables from certified vendors work reliably. For guaranteed interoperability, HPE-qualified cables are recommended.
How do I install the HPE 813874-B21 transceiver?
Simply insert the module into an empty SFP+ slot until it clicks into place. Confirm link status via LED indicators on the host device.
What maximum data transfer rate does the HPE 10GBase-T Transceiver support?
It supports full-duplex 10 Gbps Ethernet throughput as defined by IEEE 802.3an. Backward compatibility to 1 Gbps and 100 Mbps auto-negotiation is also supported.
Will this transceiver work in non-HPE network equipment?
It may operate in any IEEE 802.3an-compliant SFP+ port, but HPE only certifies it for HPE-branded hardware. Third-party compatibility is not guaranteed for full feature support.
What is the operating temperature range for the HPE 813874-B21?
The transceiver operates between 0 °C and 70 °C (32 °F to 158 °F). Storage temperature ranges from –40 °C to 85 °C (–40 °F to 185 °F).
Does the HPE 10GBase-T SFP+ Transceiver include a warranty?
Yes, it carries a one-year limited hardware warranty backed by HPE. Coverage extends according to your HPE support agreement.
How does 10GBase-T compare to optical SFP+ modules?
10GBase-T uses standard copper cabling for lower cable cost and simpler re-use of existing infrastructure. Optical SFP+ offers longer reach, lower latency and reduced power per port.
Can I mix 10GBase-T modules with fiber SFP+ modules in the same switch?
Yes, as long as the switch supports both module types. Ensure port configurations and transceiver types match the desired link media.
How do I troubleshoot link issues with the HPE 813874-B21?
Verify cable type, length and connector integrity, check port configuration and firmware, and confirm LED link/activity indicators. Replace suspect cables or modules to isolate faults.
Where can I purchase genuine HPE 813874-B21 SFP+ Transceivers?
Buy from authorized HPE resellers, the official HPE Store or HPE’s website using SKU 813874-B21. Confirm Genuine HPE part labeling for authenticity.
