System Administration

5.1.3 SCS System Architecture

The SCS software design uses both RAM (volatile) and Compact Flash (non-vola- tile) memory. Any system changes are maintained in RAM until they are written to the Compact Flash memory. A read-only memory system is used since Compact Flash memory devices have a limited number of read-write cycles.

After making administrative changes to the system, the root user must run the save command to write the changes to the non-volatile memory. If the data changes are not saved, the parameter changes will be lost in the event of a power failure.

5.2 Initial Sysadmin Access

When the SCS is first powered up, you may want it to be configured to operate with your network. You will use ssh to access the SCS.

The SCS product uses familiar Linux commands to administer the system. This manual will list those Linux commands that are important for the SCS sysadmin to know; other Linux / UNIX commands are discussed in a myriad of Linux reference and training manuals.

5.2.1 Connect using a Terminal

Connect the SCS’s Console port to your terminal, or to a computer using a terminal emulation program. When you successfully connect with the SCS, your terminal will show the header and login prompt:

Later, after you change your SCS’s Hostname, your new hostname information will be shown in your login line (in place of scs.localdomain, above).
