Chapter 1 - Overview
The SM24DP4XA is a next generation Layer 2 managed switch with 128Gbps switching capacity. It provides up to
(24) dual speed fiber slots and (4) 10Gig aggregation ports, it’s an ideal switch for fiber aggregation applications.
The SM24DP4XA delivers 20 GbE SFP ports, 4 Combo GbE RJ45/SFP ports, 4 GbE/10G SFP+ ports, RJ45 Console
port and OOB Management port with built-in AC and dual DC power support. The SM24DP4XA provides front
panel access to all power, data, and management ports to facilitate desktop or rack-mount installations.
The SM24DP4XA is ideal for environments that require advanced features for granular control which is a must for
easy network configuration and management where you need a successful installation for high-bandwidth VoIP,
Gigabit-to-the-Desktop deployments, and converged voice and data networks.

•ITU-T G.8031 Ethernet Linear Protection Switching (EPS)
•ITU-T G.8032 Ethernet Ring Protection Switching (ERPS)
•Ethernet Virtual Circuits (EVC) for EPL and EVPL services
Benefits
Exceptional Precision with IEEE 1588v2 (TC) : The switch performs IEEE1588v2 with transparent clock capability,
implementations in hardware, so there is no performance penalty on packet processing. The hardware
architecture ensures low latency and high time accuracy –which is critical for delay-sensitive financial and mobile
applications.
Superior reliability through OAM and CFM for Service Assurance : Service assurance is provided through a rich
feature set of operations, administration, and maintenance (OAM) functionalities. It can simplify and facilitate
the management of Ethernet networks, resulting in diminishing operational costs. The Ethernet access device
also offers standards-based fault and performance management in adherence with Y.1731 PM and 802.1ag
connectivity fault management (CFM) standards. These features contribute to significant reduction in operational
expenditures and allows for troubleshooting without expensive truck rolls.
