• Why Choose This Product?

• The H3C US552S is a practical choice for organizations that need high Gigabit port density without moving to a larger chassis-based platform. Its 48 copper ports provide twice the access density of the US528S, while four Gigabit SFP uplinks support fiber connectivity for upstream network expansion. IRF2 adds a useful scaling path for compatible H3C deployments, while built-in authentication, ACL, routing, and traffic-control features support structured enterprise network management. For replacement and modernization projects, this combination can help consolidate access connectivity and extend an existing H3C switching architecture without unnecessary infrastructure redesign.
