High-density Chassis Ethernet Switch built with 4 module slots and redundant power supply. It provides great porting flexibility for network deployment by offering various combinable management modules and standard interfaces. For instance, one management module can be collaborated with three standard modules, or two management modules work with two standard modules to mutually perform system backup. 4 open module slots design: (1) 2 Management Modules with 2 Standard Modules. (2) 1 Management Module with 3 Standard Modules. 160-port Gigabit copper, 156-port Gigabit SFP, 60-port 10G SFP+ and 6-port 40G QSFP+. Hot-swappable switching modules. Non-blocking wire-speed Layer 2 and Layer 3 switching. 1 RJ45 serial console interface on Management Module for switch basic management and setup. 100~240V AC dual power redundant. IP stacking technology -- connect with stack member via any Gigabit /10G/40G interface. IP Routing protocol supports RIP v1/v2, OSPF v2, BGP4. Routing interface provides VLAN routing mode. Policy-based Routing(PBR) for IPv4 and IPv6. VRRP protocol for redundant routing deployment. Supports route redistribution.
