HP J4857A: ProCurve 9300 8-port Gigabit module (mini-GBIC SX/LX).

The HP J4857A is a ProCurve 9300 managed 8-port Gigabit module for the Switch 9300 series chassis (9308M and 9315M), providing 8 fibre Gigabit ports via mini-GBIC transceivers in either SX (multimode, short-reach) or LX (single-mode, long-reach) variants, which must be ordered separately to match the required fibre type and distance. It is a modular fibre expansion card rather than a standalone switch, fitting into any available line-card slot in an existing 9300-series chassis. This is the correct spare for restoring fibre port capacity after a module failure or for expanding an existing 9300 chassis with additional Gigabit fibre uplinks or server connections. Specifiers should confirm chassis slot availability and required SFP transceiver type before ordering. Tech-Star (UK-based, shipped worldwide) supplies refurbished HP hardware for engineers maintaining or expanding existing Switch 9300 deployments.
