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.
