1 INTRODUCTION OVERVIEW The ECS3510-28MT switch is a intelligent switch with 24 10/100BASE-T ports, and four Gigabit combination ports1 that are comprised of an RJ-45 port and an SFP transceiver slot. There is also an SNMP-based management agent embedded on the main board. This agent supports both in-band and out-of-band access for managing the switch. This switch provides a broad range of powerful features for Layer 2 switching, delivering reliability and consistent performance for your network traffic.
CHAPTER 1 | Introduction Description of Hardware SWITCH ARCHITECTURE This switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. This switch uses store-and-forward switching to ensure maximum data integrity.
CHAPTER 1 | Introduction Description of Hardware Each port also supports auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated. SFP SLOTS The Small Form Factor Pluggable (SFP) transceiver slots are shared with four RJ45 ports (combination ports). In its default configuration, if an SFP transceiver (purchased separately) is installed in a slot and has a valid link on its port, the associated RJ-45 port is disabled and cannot be used.
CHAPTER 1 | Introduction Description of Hardware Table 1: Port Status LEDs (Continued) LED Condition Status 1000M On/Blinking Green The port has a valid 1000 Mbps link. Blinking indicates activity.
