ARM LEDs
The ARM has two module-level LED indicators (STATUS and DIAG) (see Figure 165).
•
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.
or amber) that signals whether diagnostics are being run on the module.
NOTE
During the ARM 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 about ARM LED activity, see “I/O Module LEDs” on page 293.
Service Ports
The ARM has two front-panel service ports: one port is a DB-9 connector; the other is a micro HD-15
connector (see Figure 165). Both ports are reserved for use only by Extreme Networks technical support
personnel for diagnostic purposes.
