HP J8706A Hewlett-Packard HP ProCurve networking / enterprise server hardware Optical Transmission Module

The HP J8706A is a ProCurve switch zl 24-port Mini-GBIC module, a line card that fits the module slots of the 5400zl and 8200zl chassis switches to add 24 fibre Gigabit ports via mini-GBIC (SFP) transceivers, which must be ordered separately to match the fibre type and distance required. It is a pure fibre-uplink expansion card rather than a standalone switch, giving an existing zl chassis additional Gigabit fibre capacity for uplinks, server connections or inter-switch links. The zl platform’s modular design means this card can be added, removed or relocated between chassis slots without affecting other installed modules. This is the correct spare for restoring fibre port capacity after a module failure or for expanding an existing zl chassis. Specifiers should confirm chassis slot availability and required SFP transceiver types before ordering. Tech-Star (UK-based, shipped worldwide) stocks and tests this as part of its refurbished HP range, for maintenance, redundancy or expansion of zl-series systems.
