268 Extreme Networks Consolidated Hardware Guide
BlackDiamond 6800 Series I/O Modules
NOTE
During the ATM 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 ATM module LED activity, see I/O Module LEDs on page 271.
Service Ports
The ATM 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 135). Both ports are reserved for use only by Extreme
Networks technical support personnel for diagnostic purposes.
