H3C S6820-56HF — 25GbE/100GbE Data Center Top-of-Rack Switch
Technical Identity
The H3C S6820-56HF is a 1U data center switch from the H3C S6820 series with 48x 25G SFP28 ports and 8x 100G QSFP28 ports, per the H3C S6820 hardware documentation. H3C documents that the 25GE SFP28 interfaces support autosensing down to 10GE/1GE. The switch runs the H3C Comware operating system. Note: the unit label reads H3CS6820-56HF (brand prefix printed together with the model). Condition: Refurbished.

Engineering Context
The S6820 series is the H3C 25G/100G data center access line: 48 SFP28 server-facing ports with 8 QSFP28 uplinks in 1U mirrors the standard 25G top-of-rack design, giving a 1200G access tier with 800G of uplink capacity per switch. Because H3C publishes model-specific figures in its hardware guides, capacity, power, and airflow options for this exact unit should be verified against the H3C S6820 hardware information documents and the unit label.
Use Cases
25GbE server access in data center racks with 100GbE uplinks
Leaf tier in 25G/100G leaf-spine fabrics built on H3C Comware platforms
Migration from 10GbE access: the SFP28 ports accept 10G optics per H3C documentation
Environments standardized on H3C / Comware management tooling
What This Is NOT
NOT the H3C S6850-56HF. The S6850 is a different H3C series with a similar 48x SFP28 + 8x QSFP28 layout; match the exact series and model on the unit label.
NOT a 400GbE platform. Uplinks are QSFP28 100G.
NOT an RJ-45 copper access switch. All 48 access ports are SFP28 cages requiring optics or DACs.
NOT a campus PoE switch. This is a data center top-of-rack platform with no inline power.
NOT supplied with transceivers, DAC cables, or rack accessories unless explicitly stated in the listing.
NO H3C software licenses or support contracts are included or transferred.
Compatibility & Hard Constraints
Optics and cables: H3C-qualified SFP28/SFP+ and QSFP28 optics and DACs; verify against the H3C S6820 transceiver compatibility documentation.
Port rates: 25GE SFP28 interfaces autosense to 10GE/1GE per H3C documentation; verify optic support per rate.
PSU and airflow: PSU type and airflow direction vary by ordered configuration — verify against the physical unit and H3C hardware guide before deployment.
Management: H3C Comware CLI and management tooling; confirm the installed software release and upgrade entitlement requirements with H3C.
Pre-deployment verification: confirm model (S6820 vs S6850 series), software release, PSU, and airflow against the unit label.
Frequently Asked Questions (FAQ)
Q. What is the H3C S6820-56HF?
The S6820-56HF is a 1U H3C S6820-series data center switch with 48x 25G SFP28 ports and 8x 100G QSFP28 ports, running the H3C Comware operating system.
Q. Do the SFP28 ports on the S6820-56HF support 10GbE?
Yes. H3C documents that the 25GE SFP28 Ethernet interfaces support autosensing down to 10GE/1GE with appropriate optics.
Q. Why does the label read H3CS6820-56HF?
The unit label prints the H3C brand prefix together with the model number. The product is the H3C S6820-56HF; verify against the physical unit label.
Q. How does the S6820-56HF differ from the S6850-56HF?
Both are H3C data center switches with a 48x SFP28 + 8x QSFP28 layout, but they belong to different H3C series with different hardware specifications. Buyers should match the exact model on the label; this unit is from the S6820 series.
Q. What optics work with the S6820-56HF?
H3C-qualified SFP28 25G, SFP+ 10G, and QSFP28 100G transceivers and DAC cables per the H3C S6820 compatibility documentation. Transceivers are not included with this unit.
