If the SSA switch is not working properly, refer to Troubleshooting Checklist for a checklist of problems, possible causes, and recommended actions to resolve the problem.
Troubleshooting Checklist
| Problem | Possible Cause | Recommended Action |
|---|---|---|
| All LEDs are off | Loss of power. | Ensure that the SSA switch was installed properly according to the instructions in Installation, and that the chassis has power. |
| No Local Management Password screen | Incorrect terminal setup. | Refer to the S-, K-, and 7100 Series Configuration Guide for proper setup procedures. |
| Improper console cable pinouts. | Refer to COM Port Pinout Assignments for proper COM port pinouts. | |
| Corrupt firmware image or hardware fault. | If possible, try to download the image to the SSA switch again. Refer to Clearing Persistent Storage or Resetting the System Password for instructions to clear NVRAM. | |
| Cannot navigate beyond Password screen | Improper username/ password combination entered. |
If you have forgotten the username or password, refer to Clearing Persistent Storage or Resetting the System Password for instructions on how to clear the password, resetting it to the default value of null (blank), using either the boot loader clearpassword command or set mode switch method. |
| Cannot contact the SSA switch through in-band management | IP address is not assigned. | See the S-, K-, and 7100 Series Configuration Guide. |
| Port is disabled. | Enable the port. See the S-, K-, and 7100 Series Configuration Guide for instructions to enable/disable ports. | |
| Host Port policy and/or management VLAN is not configured, or is configured incorrectly. | Verify that a management VLAN exists and that it is
associated with the Host Port. Refer to the S-, K-, and 7100 Series Configuration Guide for information about Host Port and management VLAN configuration. |
|
| No link to device. | Verify that all network connections between the network
management station and the SSA switch are valid and operating. If the problem persists, contact us for technical support. |
|
| One or more ports go into standby for no apparent reason | Loop condition detected. | Verify that Spanning Tree is enabled. Refer to the S-, K-, and 7100 Series Configuration Guide for instructions to set the type of STP. Review the network design and delete loops. If the problem persists, contact us for technical support. |
| User parameters (IP address, device and device name, etc.) were lost when the SSA power was cycled or the OFFLINE/RESET button was pressed | The position of Mode switch 7, Persistent Data Reset, was
changed either before cycling power or pressing the RESET button, causing the
user-entered parameters to reset to factory default settings. Clear Persistent Data that was set through Local Management. |
Reenter the lost parameters as necessary. Refer to the S-, K-, and 7100 Series Configuration Guide for instructions to configure the device. If the problem persists, contact us for technical support. |
