After you have provided the required configuration information, a confirmation message appears while the CCM stores the values in its configuration database.

You have now completed the initial login, and you may enter additional commands at the CLI prompt (>). To configure CCM ports, see Configuring Serial Port Settings in Chapter 3.

Reinitializing the CCM

Reinitializing the CCM removes configured information. This may be useful when reinstalling the CCM at another location in your network.

The CCM stores configuration information in FLASH databases. During reinitialization, the FLASH erase has two phases. The first phase erases the CCM configuration database, which contains all nonvolatile data except the IP address. The second phase erases the IP address and restores the CCM to its factory default settings.

To reinitialize the CCM:

1.Locate the recessed INIT button on the front of the CCM. You will need a tool that ﬁts inside the recess, such as an opened paper clip.

2.Insert the tool in the recess, then depress and hold the button. The ONLINE LED will blink, indicating a CCM initialization has been requested. You have approximately seven seconds to release the button before any action is taken.

After seven seconds, the ONLINE LED will blink more rapidly to conﬁrm that the CCM conﬁguration database has been erased. Continuing to hold the INIT button for a few more seconds will erase the IP address as well. The ONLINE LED will blink faster to conﬁrm the deletion.

If any portion of FLASH is erased, the CCM reboots when the INIT button is released.
