Appendix B: Cables

Twisted-Pair Cable and Pin Assignments

For 10BASE-T and 100BASE-TX connections, a twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.

Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation. (See “Cabling Guidelines” on page 4-1 for an explanation.)

Caution: DO NOT plug a phone jack connector into any RJ-45 port. This will damage the switch. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

The figure below illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.

10BASE-T/100BASE-TX Pin Assignments

Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or

100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).

The RJ-45 ports on the switch base unit support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable. When using any RJ-45 port on this switch, you can use either straight-through or crossover cable.

ES3628EA specifications

Accton Technology's ES3628EA is an advanced network switch designed to meet the growing demands of modern enterprise environments. This managed switch is engineered to provide a robust solution for delivering high-speed connectivity and reliable performance across local area networks (LANs). The ES3628EA features a 28-port configuration, combining 24 Gigabit Ethernet ports and 4 SFP (Small Form-factor Pluggable) uplink slots, allowing for flexible network design and scalability.

One of the standout characteristics of the ES3628EA is its support for Layer 2 and Layer 3 functionalities, offering network administrators enhanced control and management over data traffic. With features such as VLAN (Virtual Local Area Network) support, the switch enables efficient segmentation of networks for improved security and performance. VLAN tagging allows for the separation of different data types on the same physical infrastructure, reducing broadcast traffic and enhancing overall efficiency.

Additionally, the ES3628EA supports advanced Quality of Service (QoS) mechanisms, which prioritize critical network traffic, ensuring optimal performance for applications like voice over IP (VoIP) and video streaming. The ability to configure multiple queues allows administrators to define traffic patterns, allocate bandwidth effectively, and minimize latency.

The device also incorporates comprehensive security features, including port security, access control lists (ACLs), and support for802.1x authentication. These capabilities help safeguard sensitive data and restrict unauthorized access to the network.

Power over Ethernet (PoE) support is another significant feature of the ES3628EA. This technology allows the switch to deliver power alongside data over Ethernet cables, facilitating the connection and powering of devices like IP cameras, VoIP phones, and wireless access points, all without the need for additional power sources.

Furthermore, the ES3628EA boasts a user-friendly web-based interface for configuration and management, making it accessible for network administrators of varying expertise. In addition to the web interface, it also supports SNMP (Simple Network Management Protocol) for more advanced network monitoring and control.

Designed for reliability and performance, the Accton Technology ES3628EA is a versatile solution that integrates seamlessly into diverse networking environments, delivering the capabilities required for today’s demanding applications. Its blend of speed, security, and advanced management functionalities makes it an excellent choice for enterprises looking to enhance their network infrastructure.
