Overview
The GPP subsystem handles system control and ARM management functions. The GPP
subsystem resides outside the packet forwarding data path to optimize routing and
billing performance.
ARM LED Indicators
The ARM is equipped with two module-level LED indicators (STATUS and DIAG) (see
Figure 1-2).
The STATUS LED indicator is 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.
The DIAG LED indicator is 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.
