Questions & Answers
What is the HP ProCurve compatible Gigabit-LX-LC Mini-GBIC B Ver. (SKU J4859B-C)?
The J4859B-C is a Gigabit-LX-LC Mini-GBIC fiber transceiver supporting 1000Base-LX on single-mode fiber up to 10 km, fully compatible with HP ProCurve switches.
Which HP ProCurve switch models support the J4859B-C Mini-GBIC?
This Mini-GBIC is validated on HP ProCurve series including 2610, 2810, 2910, 3500yl, 3600, 5400zl and 8200 chassis.
What technical specifications define the J4859B-C Mini-GBIC?
It is an LC duplex 1000Base-LX SFP module, single-mode fiber, 1310 nm wavelength, up to 10 km reach, operating temperature 0–70 °C, power ≤0.8 W.
How do I install the J4859B-C Mini-GBIC in my HP switch?
Power on the switch, align and insert the module into an empty SFP port until it clicks, then connect your LC single-mode fiber cable.
Is the J4859B-C Mini-GBIC hot-swappable?
Yes. You can insert or remove the transceiver without powering down the switch, provided the network topology supports hot-swap.
What type of fiber cable do I need for this Mini-GBIC?
Use single-mode fiber cable terminated with LC connectors for optimal performance at 1310 nm over distances up to 10 km.
Can I use the J4859B-C Mini-GBIC with non-HP switches?
While optimized for HP ProCurve, it may function on other vendors’ SFP-compatible switches, though interoperability isn’t guaranteed.
How can I verify compatibility with my network equipment?
Consult your switch’s SFP compatibility matrix or HP ProCurve documentation to confirm support for the J4859B-C module.
What warranty covers the J4859B-C Mini-GBIC?
This Mini-GBIC is backed by a one-year limited warranty against manufacturing defects.
How does 1000Base-LX differ from 1000Base-SX?
1000Base-LX uses a 1310 nm laser for up to 10 km on single-mode fiber, while 1000Base-SX uses 850 nm on multimode fiber for up to 550 m.
What are the recommended operating temperatures for the J4859B-C?
The module operates reliably between 0 °C and 70 °C (32 °F to 158 °F).
How do I check link status after installation?
Verify the Link/Act LED on the switch port turns solid or blinks with traffic, indicating a successful fiber connection.
Can I deploy this Mini-GBIC in a CWDM or DWDM network?
No. The J4859B-C is designed for standard 1000Base-LX and is not compatible with CWDM or DWDM wavelength grids.
What is the typical power consumption of this transceiver?
The J4859B-C consumes ≤0.8 W during normal operation.
How many J4859B-C modules can I install in my switch?
You can install up to as many modules as available SFP slots permit, typically up to 24 in fixed-port switches or as defined by chassis capacity.
How can I troubleshoot connectivity issues with the J4859B-C?
Check fiber polarity and cleanliness, ensure matched wavelength modules, inspect switch logs for errors, and confirm the SFP port configuration.
