Chapter 4 Troubleshooting Hardware Troubleshooting Power Supply Issues Send documentation comments to [email protected] Step 3 Step 4 Step 5 Verify that the LEDs on the supervisor module display as follows: a. The Status LED flashes orange once and stays orange during diagnostic boot tests. It turns green when the module is operational (online). If the system software cannot start up, this LED stays orange. b. The System LED turns green, indicating that all chassis environmental monitors are reporting that the system is operational. If one or more of the environmental monitors reports a problem, the System LED is orange or red. c. The Active LED turns green, indicating that the supervisor module is operational and active. If the supervisor module is in standby mode, the Active LED is orange. d. Each Link LED flashes orange once and stays orange during diagnostic boot tests, and it turns green when the module is operational (online). If no signal is detected, the Link LED turns off. The link LED blinks orange if the port is bad. If any LEDs on the supervisor module front panel are red or orange after the initialization time, see the "Troubleshooting Supervisor Issues" section on page 4-14. If you have a redundant supervisor module, refer to the following website for the latest Cisco MDS 9000 Family configuration guides for descriptions of the supervisor module LEDS, how the redundant supervisor module comes online, and how the software images are handled: http://www.cisco.com/univercd/cc/td/doc/product/sn5000/mds9000/index.htm. Verify that the Status LEDs on the supervisor module and on each switching module are green when the supervisor module completes initialization. This LED indicates that the modules are receiving power, have been recognized by the supervisor module, and contain a valid Flash code version. This LED does not indicate the state of the individual interfaces on the switching modules. If a Status LED is red or orange, see the "Troubleshooting Supervisor Issues" section on page 4-14. Verify that the terminal is set correctly and that it is connected properly to the supervisor module console port if the boot information and system banner are not displayed.
