Feature Highlights

QuantaMesh 3000 Series T3048-LY2R

A powerful Top-of-Rack Switch for Cloud Datacenters

The QuantaMesh T3048-LY2R is a high performance and low latency layer 2/3/4 Ethernet switch with 48 1/10GbE SFP+ and 4 40GbE QSFP+ ports in a compact rack unit size. The 4 40GbE ports provide 160Gbps to aggregate bandwidth up to the core switch. Each 40 Gigabit Ethernet port can be independently configured as 40GbE or 4 x 10GbE for total 64 ports of 10GbE.


The QuantaMesh T3048-LY2R can be managed through an industry standard command-line interface (CLI) which reduces training and operating costs. A user friendly Web GUI is provided via a standard Web browser for switch management. The QuantaMesh T3048-LY2R also supports Simple Network Management Protocol (SNMP) both from standard MIB and private MIB for easy configuration, monitoring, and remote management for the network administrator. The Auto-Installation feature implemented in the QuantaMesh T3048-LY2R helps centralized management to simplify deployment of a truly plug-and-play experience. With the evolution from IPv4 to IPv6, the QuantaMesh T3048-LY2R is a IPv6 integrated management device.

High Availability

The QuantaMesh T3048-LY2R is designed for high availability from both hardware and software perspective. The key features include:

1+1 hot-swappable power supplies
2+1 hot-swappable fans
Out-of-band management supported
802.1D, 802.1w, and 802.1s supported
Up to 32 ports per group (LACP) and up to 64 groups
Multi-chassis LAG for preventing the risks of single point failure
Up to 32 paths ECMP routing for load balancing and redundancy
Virtual Router Redundancy Protocol supported


High-Performance L2/L3 access deployments

With the compact 1U form factor, high density 48 1/10G SFP+ and 4 40G QSFP+ ports in the front panel, front to back or back to front airflow design, the QuantaMesh T3048-LY2R is ideal for top-of-rack deployments in high-performance, highly demanding datacenters. The 1.28 terabits per second switching capacity and 960Mpps forwarding rate with low power consumption make the QuantaMesh T3048-LY2R a powerful solution to aggregate high-performance servers in the datacenter.
