High Availability and Flexibility
The DXS-3400 Series switches feature modular fans and power supplies for a high availability architecture. The hot-swappable design means that fans and power supplies can be replaced without affecting switch operation. Physical and virtual switch stacking allows the switches to be managed from a single IP address and provides redundancy for connected devices. The Switch Resource Management (SRM) feature allows the hardware table size to be changed, so that switch functions can be optimized based on the application. The DXS-3400 Series switches support 3 modes ??? IP Mode, LAN Mode and L2 VPN Mode ??? which modify the size of the Layer 2 and 3 tables for optimum efficiency.
