What customers say
Users overwhelmingly praise this expansion module for its seamless integration and essential role in scaling Catalyst 9300 networks. The plug and play installation and straightforward configuration within IOS XE are consistently highlighted as major benefits. Network engineers value the reliable, stable 40G uplinks, which meet demanding performance needs for aggregation and data center interconnects without introducing latency. The core friction point remains the premium acquisition cost, often cited as a significant investment barrier. While the module delivers exceptional enterprise grade performance, some users note frustration over strict compatibility requirements that favor official optics. Despite the price, the consensus confirms this module is indispensable for maximizing the 9300 chassis potential.
