Chapter 2 Installation and Setup This chapter describes the following: " How to decide where to install the 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
Determining the Switch Location Determining the Switch Location The switches are 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 rackmounted in a wiring closet or equipment room. Two mounting brackets are supplied with the switch. When deciding where to install the switch, ensure that: " The switch is accessible and cables can be connected easily. " Water or moisture cannot enter the case of the unit.

Insert four flathead screws and fully tighten with a suitable screwdriver, as shown in Figure 2-1. fit_rack.eps Figure 2-1 Fitting the Mounting Bracket Free-Standing Stacking the Switch and Other Devices 4. Repeat the three previous steps for the other side of the switch. 5. Insert the switch into the 19-inch rack and secure with suitable screws (not provided). Ensure that ventilation holes are not obstructed. 6.
Connecting Equipment to the Console Port Connecting Equipment to the Console Port Connection to the console port is used for direct local management. The switch console port settings are set as follows: " Baud rate — 9600 " Data bits — 8 " Stop bit — 1 " Parity — None " Flow control — XON/XOFF The terminal connected to the console port on the switch must be configured with the same settings. This procedure will be described in the documentation supplied with the terminal.
