The QuantaMesh T1048-LY4 family is the new generation of layer 2 and layer 4 Ethernet standalone switches that provide the following configuration:
  • 48 10/100/1000Base-T downlink plus 2 1/10GBase-X SFP+ uplink ports
  • 48 10/100/1000Base-T downlink plus 4 100/1000 SFP uplink ports
  • 48 10/100/1000Base-T downlink ports
The QuantaMesh T1048-LY4 is ideal for branch office access network design. It integrates advanced management and security functions for contemporary datacenter requirements.
Extensive Layer 2 Features

Equipped with full Layer 2 features like Spanning Tree, Link Aggregation Control Protocol (LACP), IGMP Snooping and Port Mirroring, the QuantaMesh T1048-LY4 provides loop-free environment, flexible throughput adjusting, best control of multicast traffic and network monitoring. Supported with 802.1Q up to 4094 active VLANs in the QuantaMesh T1048-LY4, it secures broadcast domain as well as resource access in between each VLAN.
Enhanced Security

The port security of the QuantaMesh T1048-LY4 restricts switch access with the proper MAC address. The Layer-2, -3, and -4 access control list feature provides advanced traffic filtering based on the source and destination MAC addresses, IP addresses, or TCP/UDP ports. 802.1x Port-Based and MAC-Based access control makes sure only authorized user before granted access. The storm control for unknown unicast, unknown multicast and broadcast packets render the network unable to transport normal traffic.
QoS, Bandwidth Control

The QoS technique specifies a priority tag for QoS disciplines to different traffic. When a switch receives the fame, it prioritizes the stream, puts into the proper queues, and forwards the packets. The QuantaMesh T1048-LY4 supports 802.1p, DSCP, IP Precedence and TCP/UDP port number, and gives the optimal performance for real-time applications like voice and video. The 802.1Q QoS assignment can automatically inserts a tag and processes the best effort performance for the streaming.
Simplified Management

The Quanta series can be managed through industry-standard command-line interface (CLI) which reduces the training and operating costs. A user friendly Web GUI via a standard Web browser to manage. The T1048-LY4 also supports Simple Network Management Protocol (SNMP) both from standard MIB and private MIB for network administrator to easily configure, monitor, and manage remotely. sFlow provides quantifiable accuracy for network administrator to analyzes on network traffic. With the evolution from IPv4 to IPv6, the Quanta T1048-LY4 is a IPv6 integrated management device.
Datacenter Application

The QuantaMesh T1048-LY4 is a high port density unit that is useful as a management device in datacenter server rack. The QuantaMesh T1048-LY4 can support front to back or back to front airflow for different datacenter requirements. Also, the LY4 can support AC and DC power.
