Configuring I/O Modules
Extreme Networks Consolidated Hardware Guide
265
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.
PoS Module LED Indicators.
The PoS modules are equipped with two module-level LED indicators
(STATUS and DIAG) and one port-level LED indicator for each network interface port on the PoS
module as shown in Figure 133.
•
STATUS LED—Located near the top end of the PoS module 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 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.
NOTE
During the PoS 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 PoS module LED activity, see “I/O Module LEDs” on page 277.
Service Ports.
The PoS modules are 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). Both ports are
reserved for use only by Extreme Networks technical support personnel for diagnostic purposes.
