About This Guide
Purpose
This guide gives specific information on how to operate and use the management
functions of the switch.
Audience
The guide is intended for use by network administrators who are responsible for operating
and maintaining network equipment; consequently, it assumes a basic working
knowledge of general switch functions, the Internet Protocol (IP), and Simple Network
Management Protocol (SNMP).
Conventions
The following conventions are used throughout this guide to show information:
Note: Emphasizes important information or calls your attention to related features or
instructions.
Caution: Alerts you to a potential hazard that could cause loss of data, or damage the
system or equipment.
Warning: Alerts you to a potential hazard that could cause personal injury.
