This chapter provides information on the following topics:
Before you install an ATM module, ensure that the following items are included in the package:
If anything is missing, contact your Cisco Systems customer service representative.
This section lists international regulatory information for the ATM modules.
U.S. regulatory information for this product is in the front matter of this manual.
Before you configure the LANE client, ensure that the device you are connecting to the ATM module is configured as one of the following LANE servers:
Multicast server that floods traffic addressed to an unknown destination in emulated LANs (ELANs). It also forwards multicast and broadcast traffic to the appropriate clients. | |
Database server that assigns a LANE client to particular ELANs by directing them to the LANE server (LES) that corresponds to the ELAN. There is one logical LECS per administrative domain. This serves all ELANs within that domain. | |
LANE server that implements the control function for a particular ELAN. There is only one logical LES per ELAN. It is identified by a unique ATM address.
|
After LESs are properly configured, you can connect the devices to the ATM module. Record the VLAN ID numbers and ELAN names that are configured in the LECS. You will need this information when you configure the ATM module LANE client.
For additional information about LANE, refer to the related Cisco publications listed in the section entitled "About This Guide."
For detailed information about configuring LECSs, refer to your ATM device documentation.
The following components are required for using MPOA across an NBMA network:
Typically, a switch (or module within a switch) that provides direct VCCs between the edge devices or hosts whenever possible and forwards Layer 3 packets over these shortcut VCCs. A router can be designated as an MPC. The MPCs must be used with MPSs. | |
An ATM router with MPOA or a switch with a Route Switch Module (RSM) installed. The Catalyst 5000 series switch can be configured with an RSM/VIP2 (with an ATM interface) and configured as an MPC or an MPS. The MPS must be used with MPCs. | |
Intersubnet routing protocol that allows intermediate routers to forward packets hop-by-hop. |
After MPSs are properly configured, you can connect the devices to the ATM module. Record the ELAN ID numbers and ELAN names that are configured in the MPS. You will need this information when you configure the ATM module MPOA client.
For additional information about MPOA, refer to the related Cisco publications listed in the section entitled "About This Guide."
Before you install the ATM module, ground yourself by touching a piece of metal to avoid electrostatic discharge (ESD). You should also take the following precautions to prevent damage to the board:
After the ATM module is installed and the cables are connected, the module automatically runs a power-on self-test (POST) to verify that the ATM module is operational. This POST is specific to the ATM module. The Catalyst switch continues its normal operation.
Before you install the ATM module, select an expansion slot on the front panel of the switch. Figure 2-1 shows a Catalyst 2900 XL switch with blank faceplates for expansion slot 1 and expansion slot 2. If you are replacing an existing module, refer to the "Removing the Module" section before you begin.
 | Warning Class 1 laser product. |
| Warning Avoid exposure to the laser beam. |
 | Caution When installing an ATM MM Fiber or ATM SM Fiber module, do not remove the rubber plugs from the fiber-optic connector on the module or the rubber caps from the fiber-optic connector on the cable until you are ready to connect the cable to the module. The plugs and caps protect the fiber-optic connectors from contamination and ambient light. |
| Caution Before you install the ATM module, ground yourself by touching a piece of metal to avoid electrostatic discharge. |
To install the module in an expansion slot, follow these steps:
Step 1 Loosen the thumbscrews that secure the faceplate to the expansion slot.
Step 2 Remove the faceplate and store it for later use.
Figure 2-2 shows a Catalyst 2900 XL switch with an empty expansion slot.
Step 3 Align the sides of the module with the guide brackets along the inside of the chassis slot.
| Caution Do not force the ATM module into the expansion slot. Doing so might damage the module and the switch. |
Step 4 Slide the ATM module into the expansion slot until it seats snugly into the connector on the switch backplane.
Step 5 Tighten the thumbscrews on the front panel of the module.
The module is properly seated when the front panel is flush with the front panel of the switch.
This section explains how to connect cables to installed ATM modules. Both fiber-optic and UTP cable connections are discussed.
To connect a fiber-optic cable to the ATM 155 SM-MR or ATM 155 SM-LR module, do the following:
Step 1 Remove the rubber plugs from the connector on the cable and store the plugs for future use.
Step 2 Connect the cable to the connector on the ATM module, as shown in Figure 2-3.
Step 3 Connect the other end of the fiber-optic cable to the remote ATM device.
To connect a UTP Category 5 cable to the ATM 155 UTP module, do the following:
Step 1 Connect the cable to the RJ-45 connector on the ATM module, as shown in Figure 2-4.
Step 2 Connect the other end of the UTP cable to the remote ATM device.
After the ATM module is installed and the cables are connected, the module automatically runs a POST to verify that it is operational. If the ATM module fails the POST, the LED on the module changes from green to amber. For more information about LED displays, refer to Table 1-1, Table 1-2, or Table 1-3. Refer to the section entitled "Troubleshooting" for troubleshooting procedures if the ATM module is not operational.
To remove an ATM module from a Catalyst 2900 XL switch, follow these steps:
Step 1 Disconnect the cable from the connector on the ATM module.
| Caution Place the rubber plugs back into the fiber-optic connector on the module and the rubber caps on the fiber-optic connector on the cable. The plugs and caps protect the fiber-optic connectors from contamination and ambient light. |
Step 2 Loosen the thumbscrews that attach the ATM module to the front panel of the switch.
Step 3 Remove the module from the switch by grasping the thumbscrews and gently pulling the module out of the slot.
Step 4 If you are not installing another module, reinstall the blank faceplate over the open chassis slot to ensure proper airflow and cooling in the chassis.
Step 5 Tighten the faceplate thumbscrews.
