Figure 50 LC connector

Connecting fiber

Step 1: Plug one end of the fiber into the SFP optical module of the Switch 8800

Family.

Step 2: Connect the other end of the fiber into the corresponding device.

c CAUTION: When the optical interface has not been connected with a fiber connector or its dust-proof mesh is open, there might be some invisible radiation emitted from the optical interface. So do not look into the optical interface directly.

Cover the optical interface if there is no connector plugged in.

Cable Routing

Recommendations

Freestanding Switch on For only selling an integrated chassis, you do not have to care about the cabling Tabletop inside or outside the cabinet. All the I/O module cables are routed from the left

side of the chassis (along the cabling channel), and the chassis power cords (AC/DC power cords) are routed in the front of the chassis.

Cabinet-MountingIf the switch is mounted in a 19-inch standard cabinet or B68-22 cabinet, the I/O Switch module cables are bound on the cabling rack at the left side of the chassis and are routed up or down to pass through the chassis top or the raised floor depending

on the available equipment room condition (that is, the signal cables are routed into the chassis either from the cabling rack on the chassis top or from the cabling trough under the floor) of the exchange office. The power cords run along the left-front of the chassis and out of the chassis either from the top or the raised floor depending on the equipment room conditions (DC power distribution cabinet, lightning protection box, and terminal block, etc.) of the exchange office.

8810, 8814, 8807 specifications

The 3Com 8814, 8810, and 8807 are renowned products from the networking giant 3Com, which played a significant role in the evolution of networking technology in the early 1990s. These devices were instrumental during a time when organizations were transitioning from traditional communication systems to more sophisticated networking solutions.

The 3Com 8814 is a multi-port networking hub designed for small to medium-sized businesses. One of its main features includes a 10Base-T Ethernet capability, allowing for fast and reliable connectivity among various devices within a local area network (LAN). The 8814 supports up to 14 connections, providing scalability for growing businesses. The hub’s ease of use is notable; it features a plug-and-play design, which aids in quick setup without requiring extensive configuration. This plug-and-play functionality, alongside its robust physical and electrical performance, made the 8814 an appealing choice for organizations looking to enhance their networking infrastructure without significant investment.

Moving on to the 3Com 8810, this device is labeled as an intelligent network switch and ushered in advancements in network management and performance. A critical element of the 8810 is its ability to support both 10/100Base-T Ethernet connections, effectively allowing mixed-speed environments. Its built-in management features, enabled by 3Com's networking technologies, offered users the ability to monitor traffic flow, manage bandwidth allocation, and configure network settings through a user-friendly interface. This switch also incorporated advanced features like VLAN support, increasing security and segmentation within networks, which proved invaluable for sophisticated networking environments.

Lastly, the 3Com 8807 represents a more versatile and high-performance switch option suited for larger networks. This model features a stackable design that allows for a broader range of scalability and redundancy. It supports both fast Ethernet and Gigabit Ethernet, ensuring that organizations can expand their network speeds as needed. The 8807 includes features for enhanced fault tolerance and link aggregation, which bolsters reliability and performance under heavy traffic loads. Its integration with 3Com's Network Management Software provided administrators with unprecedented control over their networks, empowering them to optimize performance and troubleshoot issues effectively.

Overall, the 3Com 8814, 8810, and 8807 exemplified the company's commitment to innovation in networking technology, providing businesses with the tools necessary to develop efficient, scalable, and reliable network infrastructures. Each of these devices played a crucial role in shaping the landscape of networking, emphasizing ease of use, management capabilities, and performance.
