Syntax Conventions
• The GS-1524 / GS-1548 may be referred to as the “Switch”, the “device”, or the
“system” in this User’s Guide.
• Product labels, screen names, field labels and field choices are all in bold font.
• A key stroke is denoted by square brackets and uppercase text, for example,
[ENTER] means the “enter” or “return” key on your keyboard.
• “Enter” means for you to type one or more characters and then press the
[ENTER] key. “Select” or “choose” means for you to use one of the predefined
choices.
• A right angle bracket ( > ) within a screen name denotes a mouse click. For
example, Maintenance > Log > Log Setting means you first click
Maintenance in the navigation panel, then the Log sub menu and finally the
Log Setting tab to get to that screen.
• Units of measurement may denote the “metric” value or the “scientific” value.
For example, “k” for kilo may denote “1000” or “1024”, “M” for mega may
denote “1000000” or “1048576” and so on.
• “e.g.,” is a shorthand for “for instance”, and “i.e.,” means “that is” or “in other
