2. Verify that the Main menu is displayed, pressing Return to redraw the screen as necessary. 3. Select menu option Set Module Mode by pressing 4 followed by Return. 4. In response to the prompt Set Federated "y" or "n", press y for a federated switch or n for a standalone Switch, followed by Return. 5. In response to the prompt Set Redundant "y" or "n", press y if a second QM503 is, or will be, installed in slot Ctrl B, otherwise press n followed by Return. 6. After several seconds the Main menu should be displayed again. 7. Cycle the power on the interconnect by turning off the power (on both QM561 power supply units if fitted) for several seconds, then turning the power back on again. 7.5 Checking the QM503 Controller Card LED The QM503 controller card has a set of LEDs that indicate the status of the interconnect. Check the LEDs to verify the correct installation of the QM503s and the QM584 clock cables. Table 7-2 shows the meaning of the LEDs. Note that where QM503s are installed in both slots Ctrl A and Ctrl B to provide redundancy, the LED status should be the same for both QM503s. If an LED indicates an error status, refer to the diagnostics section.
