Cisco L-M9148S-PL12= MDS 9148S 12-Port Upgrade License | Fibre Channel — L-M9148S-PL12=

Expand your MDS 9148S fabric with a 12-port upgrade license designed for 16G Fibre Channel environments. For storage teams, this is the practical way to grow SAN connectivity without swapping out the switch or redesigning the fabric. It preserves the installed platform while unlocking additional port capacity for hosts, storage arrays, and inter-switch connectivity. That matters when uptime, change control, and capital efficiency all sit on the same approval path. Instead of replacing a working switch to gain more connectivity, you extend the value of the existing Cisco MDS 9148S and keep the environment aligned with operational standards. The result is a cleaner expansion model for data centers that need more attached devices, more segmentation flexibility, or more room for future consolidation. This license is a fit for teams that want predictable scaling on a proven SAN platform. It supports measured growth, keeps procurement focused on the capacity you actually need, and helps avoid the cost and disruption of a hardware refresh before it is justified. Ideal For Adding ports to an existing MDS 9148S SAN switch Expanding Fibre Channel connectivity for new servers or storage arrays Delaying hardware replacement while increasing fabric capacity Standardizing licensed port growth across a data center SAN Why This Product 1 Adds 12 ports without a switch replacement 2 Supports 16G Fibre Channel SAN environments 3 Keeps expansion tied to the installed MDS 9148S platform 4 Uses the exact Cisco MPN for procurement and support alignment
