Configuring I/O Modules

ARM LED Indicators. The ARM is equipped with two module-level LED indicators (STATUS and

DIAG) (see Figure 131).

• STATUS LED—Located near the top end of the ARM 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 ARM 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 ARM module LED activity, see “I/O Module LEDs” on page 271.

Service Ports. The ARM module is equipped with two front-panel service ports: one port is a DB-9

connector; the other is a micro HD-15 connector (see Figure 131). Both ports are reserved for use only by

Extreme Networks technical support personnel for diagnostic purposes.
