features or instructions.
C AUTION : Alerts you to a potential hazard that could cause loss of data, or
damage the system or equipment.
W ARNING : Alerts you to a potential hazard that could cause personal injury.
RELATED PUBLICATIONS The following publication details the hardware features of the switch,
including the physical and performance-related characteristics, and how to
install the switch:
The Installation Guide
Also, as part of the switch’s software, there is an online web-based help
that describes all management related features.
