BlackDiamond 6800 Series I/O Modules
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 84 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 133.
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 139).
• 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.
