Hardware Reference 5-1

Chapter 5: Hardware Reference

Before connecting any network device to this hub, please

review Chapter 2 for information on system installation,

Chapter 3 for a brief look at common network architectures,

and Chapter 4 for information on system configuration via the

menu-driven VT-100 console interface. This chapter describes

the hardware features of the HP 100Base-T Hubs. If you are

not sure how to make network connections, or do not

understand the hub’s indicators, you should refer to this

chapter.

The HP 100Base-T Hubs provide a manageable 100 Mbit/s Fast

Ethernet stack. It also supports optional network Switch Port

Modules that can be used to connect the hub (or stack) to the

extended network with 10/100Base-TX or 100Base-FX media

types. Moreover, these Switch Port Modules serve to break up

the local collision domain, allowing you to overcome the

limited network diameter normally associated with Fast

Ethernet.

This hub provides a simple interface for configuring or

monitoring network connections. Figure 5.1 shows the Hub-

12TXM front panel, which includes a comprehensive array of

indicators, 12 RJ-45 station ports, and an Expansion Slot for

plugging in an optional Switch Port Module. Each Hub-

12TX/Hub-12TXM model has similar indicators and other front

panel components. However, note that the Management Mode

LEDs,

Master and Backup, are only present on the Hub-12TXM.
