Syntax Conventions
• The ES-2024A and ES-2024PWR may be referred to as the “ES-2024”, “Switch”, the
“device”, the “system” or the “product” in this User’s Guide. Differentiation is made
where needed.
• 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.
• Command keywords are in courier new font.
• 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.
• An arrow (-->) indicates that this line is a continuation of the previous line.
• 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 words”.
