Caution: Regardless of which chassis is used, the chassis system must be dedicated to
DFE-Gold modules (4xxxxx) only. Do not insert 7xxxxx modules or other legacy modules
into the same chassis with 4xxxxx modules as this will render the chassis inoperable.
Precaución: Cualquiera que sea el chasis que utilice, recuerde que el sistema debe
aplicarse exclusivamente a los módulos DFE (Distributed Forwarding Engine) de la serie
Gold (4xxxxx). No inserte módulos 7xxxxx ni otros módulos legado dentro de un chasis
con módulos 4xxxxx. Si lo hace, el chasis no funcionará.
