14CHAPTER 1: PRODUCT OVERVIEW

A Switch 8800 supports up to 4500 W (220 V)/2250 W (110 V) power to its PDs. It determines whether to deliver power to a newly detected PD depending on the power it currently supplied.

PoE entry area

The PoE-supported Switch 8807/Switch 8810/Switch 8814 chassis has a PoE entry area between the two power supply units. You can insert a PoE 3C17510 Switch 8800 PoE Entry Module into this area, and connect this module to a 3C17509 Switch 8800 External PoE Power Rack so as to import the output power of the External Power Rack unit.

To implement the PoE function on the Switch 8800 Family, PoE-capable interface module is required. There are two modules are PoE-capable:

3C17528 Switch 8800 48-port 10/100/1000BASE-T

3C17532 Switch 8800 48-port 10/100/1000BASE-T Access

Both of these I/O Modules are PoE-capable, and will function with the addition of a 3C17529 PoE Option (PoE DIMM Module).

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.
