SCSxx05/SCSxx20 User Guide 7: System Administrator and User Functions

7-3

If You Misplace the Sysadmin Password

You can lock the system down and prevent programming access if you

misplace your password. If this should happen, recover the system as follows:

1. Connect a terminal or PC running terminal software to the terminal port on

the SCS.

2. Power up the SCS.

3. At the boot prompt, type ?.

4. At the second boot prompt, type linux single and press Enter.

5. At the # prompt, type passwd sysadmin and press Enter.

6. Enter the new password and press Enter.

7. At the prompt, enter the new password again and press Enter.

8. Type reboot and press Enter.

9. Once the system reboots, log in using the new sysadmin password.

User Access and Functions

The user can be any person who is assigned a user name and password by the

system administrator. The system may have up to 200 unique users (including

sysadmin, the only default user). For security reasons, users can change their

own password.

For the most part, users access the SCS through the network connection. In

general, only the system administrator uses the terminal port, as it is hardwired to

the chassis.

Network Port Access

To connect to the SCS network port, use a TCP/IP Telnet client to Telnet to the

IP address assigned to the SCS, or use SSH.
