Innovations

The T640 platform introduced the new Gibson architecture, as well as the first 40 Gigabit/sec per slot router. The RE-3.0 600MHz Routing Engine was also released with the T-series, and later made available to all M-series routers except the M7i and M10i.

T640->T1600 upgrade

The T640 chassis can be upgraded to a T1600 chassis whilst fully operational in a process that is not service affecting. The following components are replaced: 1. Power Entry Modules 2. Switch Interface Boards 3. Front Panel (re-badge from T640 to T1600) On certain older T640s the fan tray must also be replaced. The upgrade kit has the code "T1600-2-80A-U" and has a RRP of $275k
