Description
MES5400-24 switches are high performance devices with 40GBASE-R and 100GBASE-R interfaces that can be used as aggregation switches in carrier networks and as Top-of-Rack or End-of-Row switches for data centers.
The switch ports support speed of 1 Gbps (SFP), 10 Gbps (SFP+), 40 Gbps (QSFP+), and 100 Gbps (QSFP28). HG interface split mode supports speed of 1 Gbps, 10 Gbps, and 25 Gbps. Split mode allows to split up to 6 HG interfaces for a total of 24 TWE interfaces .
Fault tolerance of the devices is ensured by redundant power supplies (1+1) and the use of replaceable fans.
The redundant and hot-swappable fans and AC/DC power supplies along with advanced hardware monitoring functions provide high reliability and uninterrupted services.
The devices support EVPN/VXLAN technology to create networks with simple, high-performance and scalable data center architecture.
