BlackDiamond 6800 Series I/O Modules

Physical Description

This section describes the components and the LEDs of the MPLS module, as shown in Figure 133.

The MPLS module has the following key components:

• Two high-performance network processors

• A GPP subsystem

The network processors are high-performance, programmable devices that enhance the Extreme “i”

chipset to support expanded functionality, features, and flexibility.

The GPP subsystem handles system control and MPLS management functions. The GPP subsystem

resides outside the packet forwarding data path to optimize routing and billing performance.

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

(STATUS and DIAG) (see Figure 133).

• STATUS LED—Located near the top end of the front panel, near the ejector/injector handle. This

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

status of the module.

• DIAG LED—Located beside the STATUS LED. The LED is a bi-color LED (displaying in either green

or amber) that signals whether diagnostics are being run on the module.

NOTE

During the MPLS module boot up, the Status and Diag LEDs may be incorrectly lit to solid green or

solid amber. The LEDs reflect their true state after approximately 30 seconds when the module has

completed its boot cycle.

For more information on MPLS module LED activity, see “I/O Module LEDs” on page271.

Service Ports. The MPLS module is equipped with two front-panel service ports: one port is a

subminiature DB-9 connector; the other is a micro HD-15 connector (see Figure 133). The ports are

reserved for use only by Extreme Networks technical support personnel for diagnostic purposes.
