> # MPS-14/2 Module Upgrade

> Caution | A software upgrade is only partially disruptive for the MPS-14/2 module. The NX-OS software continues to support nondisruptive software upgrades for Fibre Channel modules in the switch and for the switch itself.

> The MPS-14/2 modules have 14 Fibre Channel ports (nondisruptive upgrade) and two Gigabit Ethernet ports (disruptive upgrade). MPS-14/2 modules use a rolling upgrade install mechanism for the two Gigabit Ethernet ports where each module in a given switch can only be upgraded in sequence. To guarantee a stable state, each MPS-14/2 module in a switch requires a 5-minute delay before the next module is upgraded.
