Connecting the Device

This chapter describes how to connect a NetScreen-5GT ADSL device to the network and
connect the power. If you are using the optional NetScreen-5GT ADSL rack mount kit,
rack mounting instructions are included at the end of this chapter.
Note: For safety warnings and instructions, refer to the NetScreen Safety Guide. The
instructions in this guide warn you about situations that could cause bodily injury. Before
working on any equipment, be aware of the hazards involved with electrical circuitry and
be familiar with standard practices for preventing accidents.

ONNECTING THE
You can establish a high-speed connection to a remote site through an ADSL line, and
provide firewall and general security for your network. This section describes how to
connect the NetScreen-5GT ADSL device to the network.
Connecting the ADSL Port
Connect the provided ADSL cable from the ADSL port on the NetScreen-5GT ADSL
device to your telephone outlet. The ADSL port on the Annex A version of the device uses
an RJ-11 connector, while the Annex B version uses an RJ-45 connector. In the case of
Annex B models, the cable you connect from the ADSL port to the telephone outlet is
identical in appearance and wiring to a straight-through 10 Base-T Ethernet cable.
Warning: Make sure that you do not inadvertently connect the Console, Modem, or
Ethernet ports on the NetScreen device to the telephone outlet.
The ADSL line is your primary connection to an outside network. For a backup data link
to an outside network, you can either connect an Ethernet cable from the Untrusted port
on the NetScreen-5GT ADSL device to an external router, DSL modem, or cable modem,
or connect a serial cable from the Modem port on the device to an external modem.
Warning: You cannot connect both the Untrusted port and the Modem port on the device
to an outside network at the same time.
Connecting Splitters and Microfilters
A signal splitter divides the telephone signal into low-frequency voice signals for voice
calls and high-frequency data signals for data traffic. Your service provider usually
installs the splitter as part of the equipment that connects your site's telephone lines to
the provider's network.
