Chapter 12 Managing Modules Connecting to a Module Send documentation comments to [email protected] Table 12-3 Module States Module Status Output powered up testing initializing failure ok power-denied active HA-standby standby Description The hardware has electrical power. When the hardware is powered up, the software begins booting. The switching module has established connection with the supervisor module and the switching module is performing bootup diagnostics. The diagnostics have completed successfully and the configuration is being downloaded. The switch detects a switching module failure upon initialization and automatically attempts to power-cycle the module three times. After the third attempt it continues to display a failed state. The switch is ready to be configured. The switch detects insufficient power for a switching module to power up. This module is the active supervisor module and the switch is ready to be configured. The HA switchover mechanism is enabled on the standby supervisor module (see the "HA Switchover Characteristics" section on page 10-2). The warm switchover mechanism is enabled on the standby supervisor module (see the "HA Switchover Characteristics" section on page 10-2). Connecting to a Module At any time, you can connect to any module using the attach module command. Once you are at the module prompt, you can obtain further details about the module using module-specific commands in EXEC mode. To attach to a module, follow these steps: Step 1 Command switch# attach module 6 switch(standby)# Step 2 switch(standby)# dir bootflash: Purpose Provides direct access to the specified module (in this example, the standby supervisor module is in slot 6). Provides the available space information for the standby supervisor module. Note Type exit to exit the module-specific prompt. Tip If you are not accessing the switch from a console terminal, this is the only way to access the standby supervisor module.
