Power-onSelf-TestThe 7600 Card’s automatic Power-On Self-Test verifies that every component in the system is fully functional.

While the Power-On Self-Test is in progress, the Power LED is green. When the Power-On Self-Test is completed, the Power LED maintains a steady green and the Active orange LED flashes to indicate that the unit is functioning. If the unit is not functioning, the light goes off; in such a case, contact your supplier.

The Power-On Self-Test should take a maximum of sixty seconds.

Normal operation After completion of the Power-on Test, the 7600 begins normal operation automatically. The LEDs continue to display the system status of the 7600 Card module as well as the individual data connections of each Fast Ethernet LED display.

Fast Ethernet Status Referring to Figure 2-2, each of the 16 multi-color LEDs corresponds to Indicators the 16 Fast Ethernet ports in each connector on the front panel,

according to the same geometrical configuration. Each multi-color LED can appear in one of three states: green, orange or off.
