Chpater1 Switch Description
1.1 Overview
Thank you for choosing the VNT5103Q28PS switch system. This switch is built with
leading-edge technology to deliver reliable high-performance connectivity for your data
network.
The VNT5103Q28PS is Gigabit Ethernet Layer 2 switches with 24 10/100/1000BASE-T ports,
and four Small Form Factor Pluggable (SFP) transceiver slots for fiber connectivity.
The switch include an SNMP-based management agent, which provides both in band and
out-of-band access for managing the switch. Further, the switches support both web and
CLI-based configuration.
1.2 Power-over-Ethernet
All of the 10/100/1000 Mbps ports on the ECS4210-28P support both the IEEE 802.3af-2003
and IEEE 802.3at-2009 PoE standards that enable DC power to be supplied to attached
devices using wires in the connecting Ethernet cable.
Key Hardware
The switches consist of several key hardware components. This manual describes
Components
Each specific component, or related components, together with their installationrequirements
and procedures in each chapter. To understand each component indetail, refer to the
relevant section.

The switch contains 24 10/100/1000BASE-T RJ-45 ports that support 10/100/1000BASE-T
copper links to other devices. For more information, see “How to Connect to Twisted-Pair
Copper Ports”.
Gigabit SFP Slots
The switch contains four Small Form Factor Pluggable (SFP) transceiver slots that operate
up to 1 Gbps full duplex. For more information, see “How to Connect to SFP Fiber Optic
Ports”.
PoE Button
Pressing the PoE button on the VNT5103Q28PS front panel changes the Port LEDs to
display PoE status. For more information, see “Understanding the System Status LEDs”.
Reset Button
Pressing the reset button on the right side front panel causes the switch to restart or restore
factory default settings. For more information, see “How to Reset the Switch”.
System LEDs
For information on system status LED indicators, see “Understanding the System Status
LEDs”.
