Resetting the Catalyst 3900Resetting the Catalyst 3900
To reset the switch and run the power-on diagnostics, select Reset on the Main Menu. The Reset panel (Figure 9-1) is displayed.
Figure 9-1: Reset Panel
The following information is displayed on this panel:
- Number of Resets Since Diagnostics—Number of times the unit has been reset since the unit was powered on or ran power-on diagnostics. This number is not reset to 0 when you reset a port address table.
- Power-On Diagnostics—Indicates whether the power-on diagnostics are run when the Catalyst 3900 is powered on.
| To | Select | Then |
|---|---|---|
Reset the Catalyst 3900, clear all counters, including address tables, and run diagnostic tests | Reset Switch With Diagnostics | If the switch is part of a stack, you are prompted specify whether you want to reset a single switch or the entire stack. You are then prompted to confirm the reset and press any key to initiate the reset. This action does not clear any user-configured parameters. When the Catalyst 3900 restarts, parameters from NVRAM are used to initiate the operational parameters. |
Reset the Catalyst 3900 and clear all counters including address tables without running diagnosti | Reset Switch Without Diagnostics | If the switch is part of a stack, you are prompted specify whether you want to reset a single switch or the entire stack. You are then prompted to confirm the reset and press any key to initiate the reset. This action does not clear any user-configured parameters. When the Catalyst 3900 restarts, parameters from NVRAM are used to initiate the operational parameters. |

Note Clearing NVRAM erases all configuration parameters. If you are using the TokenChannel feature, be sure to disconnect the affected ports or disable them on the corresponding switch before clearing NVRAM. If you are using the spanning-tree option, it will be turned off and port costs and priorities will be lost, which can result in loops. Use the menus to reestablish port costs and priorities. If you are using an SNMP manager, you will need to reconfigure all IP and SNMP parameters.
If the Catalyst 3900 is connected to a terminal via the EIA 232 port, the diagnostic messages (similar to those in Figure 9-2) should appear after you reset the Catalyst 3900 with diagnostics. An abbreviated version of these messages will appear if you reset the Catalyst 3900 without diagnostics.
