What wavelength does the 4Gb LW B-series SFP use?

This SFP uses a 1310 nm long-wavelength laser optimized for 4 Gb Fibre Channel transmission over single-mode fiber.

Is the HP AN211A compatible with HP switch and storage platforms?

Yes. AN211A is fully validated for HP B-series Fibre Channel switches and HP storage arrays that support 4 Gb SFP modules.

Does this module comply with industry Fibre Channel standards?

AN211A meets FC-PI-2 and FC-PI-3 standards for 4 Gb/s Fibre Channel interoperability and performance.

Can AN211A operate at lower speeds (e.g., 2 Gb/s or 1 Gb/s)?

Yes. The module is backward-compatible and can negotiate 2 Gb/s and 1 Gb/s speeds on supported ports.

What is the operating temperature range of the AN211A?

The standard operating range is 0 °C to 70 °C (32 °F to 158 °F) ambient temperature.

How much power does the HP 4Gb LW SFP consume?

Typical power consumption is 1.0 W, ensuring energy-efficient operation in dense port environments.

How do I install the AN211A SFP in my switch?

To install, power off or hot-swap in accordance with your switch manual, insert the LC connector side into an empty SFP slot, and verify link status via CLI or management GUI.

How can I verify that the AN211A module is functioning correctly?

Check the port status LED on your switch and confirm link-up and correct speed in the switch’s management interface or CLI.

Is the HP AN211A covered by warranty?

Yes. HP provides a one-year limited warranty on the AN211A SFP module when used with supported HP products.

What is the difference between LW and SW SFP modules?

LW (Long Wavelength) SFPs operate at 1310 nm for extended reach (up to 30 km), while SW (Short Wavelength) SFPs use 850 nm for shorter distances (up to 500 m).

Can I mix AN211A with other vendor SFPs in the same Fibre Channel fabric?

Although interoperability may work, HP recommends using HP-qualified SFPs to ensure full compatibility and support.

What is included in the AN211A 1-pack package?

The single-unit package includes one HP 4Gb LW B-series 30 km FC SFP transceiver, a dust cap, and basic installation documentation.
