1-14 Overview

STP Media Port Module

Figure 1-8 shows the front panel of the six-port STP media port module. All of
its ports are configured as M ports by default. You can specify any port
configuration for the attachment ports, but you must use a special connector
called the STP cascade connector to configure the leftmost attachment port as S.
To configure the attachment ports as B and A requires two cascade connectors.
Refer to Chapter 2 for additional information on the STP cascade connector.

If you install an STP module in each of the three hub slots, 18 STP ports are
available.

UTP Media Port Module

Figure 1-9 shows the front panel of the UTP media port module, which provides
eight ports configured as M ports by default. You can specify any port
configuration (B/A, S/M, or M/M) for the attachment ports. No adapter or
special connector is needed for the UTP module. If you install three UTP
modules in the hub, 24 UTP ports are available.
