Abstract
A method includes installing an interface card having a first module of a switch fabric and a second module of the switch fabric, and an interface card having a third module of the switch fabric in a first chassis, within a first time period. The switch fabric is in a first configuration and is operable as a three-stage switch fabric after the first time period and before a second time period. The interface card having the third module is removed from the first chassis within the second time period. An interface card having a fourth module of the switch fabric and a fifth module of the switch fabric is installed in the first chassis within the second time period. The switch fabric is in a transitional configuration and is operable as a three-stage switch fabric after the second time period but before the third time period. The interface card having the third module is installed in a second chassis and the first chassis is operatively coupled with the second chassis within the third time period. The switch fabric is in a third configuration and is operable as a five-stage switch fabric after the third time period.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
