Setting Up Network Connections 3-1

Chapter 3: Setting up Network Connections

This chapter outlines several sample configurations for a local

area network utilizing specific features of an HP 100Base-T

Hubs stack.

As described in Chapter 2, up to five HP 100Base-T Hubs can

be connected together using the Stacking Cable, which attaches

to the Stacking Ports (on the rear panel), to create a complete

hub stack. Hubs connected in this way form a single collision

domain that extends across all hubs in the stack. To exclude a

hub in the stack from this collision domain, it is possible to

“isolate” it through configuration options in the VT-100

console interface (refer to Chapter 4 for details). Using the HP

100Base-T Hubs stack isolation architecture together with

optional Switch Port Modules provides considerable flexibility

when setting up network connections.

Special Architecture Used for the HP 100Base-T Hubs

Isolation Architecture

The HP 100Base-T Hubs support stack connections, or

isolation connections, for each hub. You can choose to attach a

hub to the stack collision domain, or leave it isolated except for

the management channel. This type of architecture makes the

system more flexible, provides better traffic load sharing and

data protection, improves network bandwidth utilization, and

simplifies troubleshooting.

Carefully plan your network setup to make this architecture

work well for your system. Form a common domain for

devices that need to frequently communicate with each other

by attaching them to the stack and isolate hubs containing

heavy traffic that do not need to communicate with the stack

but need to be managed. In this way you can arrange network
