Configuring I/O Modules

Extreme Networks Consolidated Hardware Guide 267

NOTE

The ATM module is a Class 1 laser device.

The default configuration of the A3cSi and A3cMi modules is as follows. Ports 1 and 3:

• Are added to the default VLAN as untagged.

• Inherit the properties of the default VLAN (VLANid and so forth).

Table 73 describes the specifications for the A3cSi optical interface.

Physical Description

This section describes the components and the LEDs of the ATM module, as shown in Figure 129.

The ATM module has the following key components:

• Two high-performance network processors

• A GPP subsystem

The network processors are programmable devices that participate with the Extreme “i” chipset to

support expanded functionality, features, and flexibility.

The GPP subsystem handles system control and I/O module management functions. The GPP

subsystem resides outside of the I/O module data path to optimize performance.

ATM Module LED Indicators. The ATM module is equipped with two module-level LED indicators

(STATUS and DIAG) and one port-level LED indicator for each network interface port on the ATM

module (see Figure 135).

• STATUS LED—Located near the top end of the ATM module front panel, near the ejector/injector

lever. This LED indicator is a bi-color LED (displaying in either green or amber) that signals the

operating status of the module as a whole.

• DIAG LED—Located beside the STATUS LED. This LED is a single-color LED (displaying in amber

only) that flashes amber when diagnostics are running on the module, and is solid amber if the

module fails the diagnostics.

• Port-level LED—Located next to the port number identifying each fiber optic network interface

connector on the front panel of the module. The port LED is a bi-color LED (displaying in either

green or amber) that signals the operating status of that network interface port.
