H3C S5120-SI series switches are widely used in the access layer Gigabit Ethernet switches, with a flexible Gigabit access and intelligent resilience architecture features is seen as the ideal of Gigabit access select. This article will focus on H3C S5120-SI series switches and their SFP optical module solutions.
I. Introduction to H3C S5120-SI series switches
H3C S5120-SI series switches provide flexible 16/24/48 10/100 / 1000M adaptive electrical interface access, support port security features to help prevent MAC address-based attacks, is widely used in enterprises Network and campus network access layer. The intelligent resilient architecture of H3C S5120-SI series switches enhances the ease of network management and maintenance. Users can connect multiple switches to form a logical independent entity to build high Performance, low cost, easy to expand, easy to manage the network system.
