Prepare the site so that the mounting, access, power source, and environmental 
requirements are met. If you have any questions about these requirements, see the 
Hardware Installation Guide for your switch on your Resource CD.

Install the switch using one of the following methods:
a. On a flat surface: Put one of the rubber footpads that came with the switch 

on each of the four concave spaces on the bottom of the switch. 

b. In a Rack: Use the rack-mount kit supplied with your switch, following the 

installation instructions included with the kit.

Apply AC power. When you apply power, the power LED can display the 

following behavior:

The power LED is yellow as it conducts a Power-On Self Test (POST). After 

the switch passes the POST, the LED turns green. The switch is now 

functional. If the POST fails, the Power LED remains yellow (see 

“Troubleshooting” in the Hardware Installation Manual for assistance).

If the power LED does not light, check that the power cable is plugged in 

correctly and that the power source is good. See “Troubleshooting” in the 

Hardware Installation Guide.

Connect devices to the switch.

Use Category 5e (Cat5e) for copper ports at 1000 Mbps 

Use NETGEAR AGM731F or AGM732F for fiber ports at 1000 Mbps.

In the room housing the switch, ensure that the ambient temperature does not 

exceed the specified operating temperature and that the environment is free of water 
condensation.

DO NOT stack equipment, or place equipment in tight spaces or in 

drawers. Be sure that your equipment has at least 2 inches (5 cm) of air space on all 
sides.

This switch can be managed through its web interface, or by using the Command 
Line Interface (CLI) through the serial console port. This guide describes the web 
method. The CLI method is also described to determine a DHCP-assigned IP 
address. For web management, follow one of the following three procedures, 
depending upon how your computer is set up.

Computer in DHCP client mode without DHCP server 

Computer with static IP address 

Computer in DHCP client mode with DHCP server

To perform extensive CLI management, see both the CLI reference manual and the 
software administration guide for your switch.

If no DHCP server is present, the switch assumes a default IP address of 
169.254.100.100 and subnet mask of 255.255.0.0. The switch is in the same subnet 
as a computer NIC port when in DHCP-client mode without a DHCP server present. 
Use this IP value to log in to the switch (see 

When the computer is in this mode, the switch must also be assigned a static IP 
address. To assign a static IP address, access the switch from the serial console 
port: 

Connect a console to the switch.
Using the null-modem cable supplied with the switch, connect a VT100/ANSI 
terminal or a workstation to the switch port labeled Console.

Start a terminal emulation program (TEP).
a. Start a TEP using the appropriate method for your operating system:

Windows users can use HyperTerminal. 

Windows Vista users should download a TEP from the Internet.

Macintosh users can use ZTerm.

UNIX users can use a terminal emulator such as TIP.

b. Configure the TEP to use the following settings (they are written below the 

connector on the switch front panel):

Baud rate: 9,600 bps

Data bits: 8

Parity: none

Stop bit: 1

Flow control: none
