34 Maintenance

Verifying the Terminal Connection

When the SNC 6101 is turned on, you can see all characters typed in the terminal. The simplest test is to

press Enter. The SNC responds by displaying a command prompt.

SNC6101 >

For additional commands that are available to control, manage, and service the SNC 6101, refer to the SNC

Firmware 4 User’s Guide.

When the SNC 6101 is rebooting, several messages are displayed on the service terminal. A successful

boot is indicated by the last message: Done executing startup script.

Connecting to the SNC 6101 using Telnet

In instances where command line access to the SNC 6101 is required and local access is not permissible,

it is possible to telnet into the SNC 6101. Telnet access should be reserved for remote update of the SNC

6101 clock, IP information, or collection of a support dump. For all other management tasks, the ADIC

Management Console is the preferred method of updating information.

Configuring the SNC 6101 for Telnet Access

If you want to access the SNC 6101 command line interface through its Ethernet port using a telnet session,

you need to add a user account.

Creating User Accounts

Telnet user accounts are separate from those created in the AMC. The user name you specify must be three

or more characters. The password must be eight or more characters. Each SNC 6101 maintains its own list

of user accounts and passwords. To create a user, you must establish a serial connection to the SNC 6101

and enter the following command:

userAdd "xxxx","yyyy"

where xxxx is your user name and yyyy is your password.

Create additional user accounts as necessary.

Unlocking the Shell

The SNC 6101 uses a command called shellLock to prevent a single telnet user from monopolizing the

command line session or overriding a serial session. Run the

command shellLock to allow only a single

diagnostic connection (telnet or serial) to the device. When telnet connects to the SNC 6101, the

shellLock value is automatically changed to '1' and the serial port is locked out. When the telnet session

disconnects, the serial port can once again access to the shell.

The shellLock setting is not persistent across boots. An AMC administrator can restart the unit thereby

unlocking the shell. To prevent a user from connecting with AMC, disconnect the Ethernet connection.

CAUTION

Modifications made to the SNC 6101 while using telnet are

permanent. There is no Cancel key to back out of changes.

Note

Refer Updating SNC 6101 Firmware on page 25 to learn the telnet procedures

required to upgrade SNC 6101 firmware.

Note

Even when the shell is locked, the ADIC Management Console (AMC) is able

to manage the SNC 6101. Any administrator with AMC can access the unit and

make changes as well, including the downloading of firmware
