Catalyst 5000 series switches support ATM switching modules using unshielded twisted-pair (UTP), single-mode fiber (SMF), multimode fiber (MMF), and coaxial cables. This chapter describes the supported ATM modules, and is divided into the following sections:
 Warning
| Only trained and qualified personnel should install or replace this equipment. |
For specifications on all ATM switching modules (except LightStream 1010 ATM modules), see Appendix A, "Specifications."
For information on configuring the ATM LANE, ATM DS3, and ATM OC-3 and OC-12 modules, refer to the Catalyst 5000 Series Software Configuration Guide. For information on configuring LightStream 1010 ATM port adapters, refer to the LightStream 1010 ATM Switch Software Configuration Guide.
LANE allows end stations to communicate through a LAN-to-ATM switch with an ATM-attached device, such as a file server, without requiring the traffic to pass through a more complex device, such as a router. LANE requires a switch that supports User-Network Interface (UNI) 3.0 or 3.1 and point-to-multipoint signaling--for example, the Cisco LightStream 1010 ATM switch.
This section describes these three modules:
ATM LANE single PHY modules require supervisor engine module software release 1.4 or greater.

| LED | Description |
|---|---|
| STATUS | The switch performs a series of self-tests and diagnostic tests. If all the tests pass, the LED is green. If a test other than an individual port test fails, the LED is red. During system boot or if the module is disabled, the LED is orange. During self-test diagnostics, the LED is orange. If the module is disabled, the LED is orange. |
| RX (Receive) | Whenever the port is receiving a cell, the LED is green for approximately 50 ms;1 otherwise, it is off. |
| TX (Transmit) | Whenever the port is transmitting a cell, the LED is green for approximately 50 ms; otherwise, it is off. |
| LINK | The LED displays the link integrity status of the ATM port. The LED is green if the link integrity is good. The LED blinks to indicate that a collision is detected on this link. |

The Catalyst 5500 switch supports the LightStream 1010 ATM switching modules, which include the ATM switch processor (ASP), carrier modules (CAMs), and port adapters. The ASP is a field-replaceable switch processor module that supports 5-Gbps shared memory. The ASP supports the feature card and high-performance reduced instruction set (RISC) processor that provides the central intelligence for the port adapters. Each CAM supports up to two hot-swappable port adapters, for a maximum of eight port adapters per Catalyst 5500 switch and up to 32 OC-3 switched ATM ports.
The LightStream 1010 ATM switch provides switched ATM connections to individual workstations, servers, LAN segments, or other ATM switches and routers using fiber-optic, unshielded twisted-pair (UTP), and coaxial cable.
