Flexible port design\n XS3800-28 offers a maximum of 24 10G fiber ports or 12 10G copper ports that are for most flexible adoption to your networks.\n\n Essentials of a core switch\n XS3800-28 is suitable for network aggregation such as SMB or campus networks that require low latency & high-density 10G backbone architectures with basic routing capability.\n\n Restore Button\n The " Restore" button saves the last workable configuration as the custom default, which means that you can fall back instantly in case of network misconfigurations.\n\n Dual Power\n Two PSUs support active-standby power redundancy that triggers backup power supply if the main unit fails.\n\n Designed for the long haul\n Quality hardware design is how Zyxel differentiate ourselves from others. We ensure stability & longevity for XS3800-28 for your networks.
