Chapter 3

Instant Internet 400-S hardware installation

This chapter helps you get to know your Instant Internet unit, and provides

instructions for connecting your unit to your LAN and WAN according to the type

of connection you are using and for mounting the unit in a rack.

Before you install the Instant Internet hardware, make sure that you are familiar

with the physical and environmental specifications of the Instant Internet 400-S

unit. For more information, refer to Appendix A, “Technical specifications,” on

page 75.

Getting to know your Instant Internet 400-S unit

The front panel of your Instant Internet 400-S unit has the following indicators

and connections:

• Nine LEDs (labeled 1–8 and Power) indicate various active or error

conditions for your Instant Internet unit. For details, refer to Chapter 6,

“LEDs: support and diagnostic functions,” on page 61.

• A seven-port autosensing, autonegotiating Ethernet switch provides a means

for connecting to your network and enables you to eliminate an extra switch

or hub on your LAN. Each port adapts to the correct network speed (10 Mb/s

or 100 Mb/s), the duplex mode of the connected device, and the correct MDI

status of the cable. For details, refer to Chapter 4, “Seven-port autosensing

switch specifications,” on page 51.

Caution: Before you install your unit, make sure that the power voltage

selector switch setting matches your power voltage. For more

information, see “Setting the voltage selector switch” on page 42.
