The Juniper Networks SIB-I-PTX5008-S-B is a switch-fabric / forwarding-control board for Juniper router platforms. It installs into a dedicated switch-fabric or forwarding-control slot in the router chassis, providing the internal switching fabric and/or forwarding-engine control functions that move traffic between line cards inside a modular chassis. This class of hardware sits behind the Routing Engine in the control/forwarding hierarchy and is typically deployed with N+1 or 1:1 redundancy across a chassis. Replacing or adding a unit of this kind is used to restore fabric redundancy, increase switching capacity, or replace a failed board without a full chassis swap. Tech-Star (UK-based, shipped worldwide) stocks genuine and compatible Juniper chassis hardware for legacy and current M-series, MX-series and T-series routers. Get in touch with our team to confirm exact chassis and slot compatibility before ordering, or to source companion spares for the same platform.
