HP J3401-69501 TSU CPU and Card Cage Kit for AdvanceStack Switch 800T.
The HP J3401-69501 is a TSU (Terminal Services Unit) CPU and Card Cage Kit designed as a replacement or spare component for the HP J3401A AdvanceStack Switch 800T. This kit includes the central processing unit and the card cage assembly, which together form the core management and expansion framework of the switch.
This component is intended for use with the HP AdvanceStack Switch 800T, a modular Ethernet switch that was deployed in enterprise LAN environments during the mid-to-late 1990s. The card cage provides slots for additional network modules, whilst the CPU handles switch management, packet forwarding decisions, and configuration tasks.
The HP AdvanceStack 800T series is a legacy product line that has been discontinued for many years. This spare part is suited for organisations maintaining existing AdvanceStack infrastructure or requiring replacement components for systems that have not yet been migrated to modern switching platforms.
