22CHAPTER 2: INSTALLING THE SWITCH

You must use the screws supplied with the mounting brackets. Damage caused to the unit by using incorrect screws invalidates your warranty.

4Repeat steps 2 and 3 for the other side of the Switch.

5Insert the Switch into the 19-inch rack and secure with suitable screws (not provided). Ensure that ventilation holes are not obstructed.

6Connect network cabling.

7Finally place a unit information label on the unit in an easily accessible position. The unit information label shows the following:

The 3Com product name of the Switch

The 3Com 3C number of the Switch

The unique MAC address (Ethernet address) of the Switch

The serial number of the Switch

You may need this information for fault reporting purposes.

Placing Units On

If the Switch units are free-standing, up to eight units can be placed one

Top of Each Other

on top of the other. If you are mixing a variety of SuperStack® 3 Switch

 

and Hub units, the smaller units must be positioned at the top.

 

If you are placing Switch units one on top of the other, you must use the

 

self-adhesive rubber pads supplied. Apply the pads to the underside of

 

each Switch, sticking one in the marked area at each corner. Place the

 

Switch units on top of each other, ensuring that the pads of the upper

 

unit line up with the recesses of the lower unit.

 

 

Stacking Units

Switch 4400 units can be stacked together and then treated as a single

 

manageable unit with one IP address. Any combination of 24-port and

 

48-port units is allowed in a single stack, as long as the total number of

 

front panel ports does not exceed the limit of 192 ports. The following

 

combinations are allowed:

 

4 x 48-port Switches

 

3 x 48-port Switches and 2 x 24-port Switches

 

2 x 48-port Switches and 4 x 24-port Switches

 

1 x 48-port Switch and 6 x 24-port Switches

 

8 x 24-port Switches

3C17204, 3C172203 specifications

The 3Com 3C172203 and 3C17204 are part of the 3Com series of networking products that have made significant contributions to local area networks (LANs) and enterprise connectivity. While they may not be as widely recognized today as newer technologies, their features, technologies, and characteristics played an essential role in enhancing network performance and reliability during their peak usage.

One of the defining features of the 3Com 3C172203 and 3C17204 is their support for Ethernet networking, which was pivotal in establishing fast and reliable communication between devices on a network. These products typically supported both 10Base-T and 100Base-TX standards, providing a flexible transition from older networks to faster Ethernet speeds. This backward compatibility ensured that organizations could upgrade their networks incrementally without needing a complete overhaul, thereby preserving their existing investments in infrastructure.

Both models also supported features designed to optimize network performance and provide enhanced management capabilities. For instance, built-in diagnostic features enabled network administrators to troubleshoot connection issues more effectively, thereby reducing downtime. Additionally, these devices incorporated intelligent switching capabilities that could manage data flow efficiently, prioritizing traffic and optimizing available bandwidth to ensure a smooth user experience, even under heavy load.

In terms of physical design, the 3C172203 and 3C17204 were built with a focus on durability. These units often featured robust metal enclosures suitable for various environments, from office spaces to more demanding industrial settings. Furthermore, their compact design allowed for easy integration into existing network setups without requiring significant rack space, making them an attractive option for enterprises looking to maximize their networking capabilities.

Security features were also a consideration in the design of these networking devices. They implemented basic security protocols to safeguard the integrity of data transmitted across the network, ensuring that unauthorized access was minimized and overall network security was enhanced.

In conclusion, the 3Com 3C172203 and 3C17204 represent an era of networking technology characterized by their support for Ethernet standards, intelligent switching capabilities, robust design, and essential management features. These products were integral in facilitating the growth of LANs and laid the groundwork for the advanced networking solutions that followed in the years ahead. While newer technologies have emerged since then, the fundamental principles established by devices like the 3C172203 and 3C17204 continue to influence contemporary networking designs.
