Switch 

•

Gigabit Ethernet configuration rules

•

How to install the switch in a rack or free-standing

•

How to connect equipment to the console port

•

How to check the installation using the Power On Self-Test (POST)

Following Safety Information

Before installing or removing any components of the switch, or before 
carrying out any maintenance procedures, you must read the safety 
information provided in Appendix A of this guide.

Determining the Switch Location

The switch is suited for use in the office, where it can be free-standing or 
mounted in a standard 19-inch equipment rack. Alternatively, the device 
can be rack-mounted in a wiring closet or equipment room. Two 
mounting brackets are supplied with the switch.
