26 CHAPTER 1: OVERVIEW
Figure1 shows the front panel of the ATM Switch Fabric Module. Note
that, in the figure, the Module is shown on its side; in the 16-slot chassis
or the 8-slot chassis you install it vertically w ith the LEDs on top.

The Module Status LED indicates the ATM Switch Fabric Module’s status.
The dual PCMCIA slots have two indicator LEDs (one for each slot), and
the RS-232 console port has one indicator LED.
Interfaces to ATM The CoreBuilder 9000 ATM Enterprise Switch provides wire-speed
interfaces for ATM OC-3c/STM-1, ATM OC-12c/STM-4, and
ATM 155 Mbps-over-UTP5 daught er cards, which are listed in Table 4.
These cell-based daughter cards are designed to be installed into ATM
Interface Modules that are inserted into CoreBuilder 9000 chassis slots.
Each ATM Interface Module can accommodate two of the following
daughter cards in any combination: OC-3c/STM-1, OC-12c/STM-4, and
155 Mbps-over-UTP5.
