> Connecting the NetScreen10 & 100 to the Network
> Follow the instructions in this chapter to set up the NetScreen-10/100 hardware and to configure the software for the first time. For further configuration options, see Chapter 2, "System Parameters" in the NetScreen Concepts & Examples ScreenOS Reference guide, on the product CD.
> This chapter contains the following sections:
> · Gathering the Necessary Tools
> · Connecting the NetScreen-10/100 to Networks and Devices

> Gathering the Necessary Tools
> The chassis can be placed on a table top or mounted in a standard 19-inch equipment rack. Table top installation requires no tools. Rack mounting requires a Phillips-head screwdriver, the rack mount bracket kit, and four screws to match the rack. Screws for attaching the mounting brackets to the chassis are provided in the NetScreen-10/100 product package. Users will have to supply screws to match rack thread size.
> Connecting the NetScreen-10/100 to Networks and Devices
> Note that if you are configuring multiple NetScreen-10/100 devices, you should install and configure them one at a time. Otherwise, you will run into IP address conflicts.
> Figure 5-1 Front View of the NetScreen-10/100
> Figure 5-2 Back View of the NetScreen-10/100
> To set up the NetScreen-10/100 hardware connections, follow these steps.

> | Note: Check your router, hub, or computer documentation to determine if you must reconfigure the device or if you must switch off the power supply when connecting new equipment to the LAN.

> 1. Install the NetScreen-10/100 in a rack (optional) or on a level surface.
> 2. Make sure that the power connection to the NetScreen-10/100 is turned off; that is, that "0" is pressed.
> 3. Connect the power cable provided in the product package, from the NetScreen-10/100 power outlet to the power supply.
> 4. Connect the NetScreen-10/100 to the network as shown in one of the examples beginning on page 2-3.
> 5. Turn on the NetScreen-10/100 and any other network devices that you had turned off.
> 6. If all cables are connected correctly, the link light for each connection will illuminate.

> | Note: You may have to supply additional cables, depending on your particular configuration. A straight-through cable is a 10/BaseT unshielded twisted pair (UTP) and is usually white. A crossover cable is a 10/BaseT UTP and is usually orange. A DTE (Data Terminal Equipment) device cannot connect to a DTE port without a crossover cable. Conversely, a DCE (Data Communications Equipment) device cannot connect to a DCE port without a crossover cable.

> For a Device Connected to: | Untrusted Port (DTE)* | Trusted Port (DCE)
> --- | --- | ---
> Workstation (DTE) | crossover | straight-through
> Switch/Hub (DCE) | straight-through | crossover
> Router§ (DTE) | crossover | straight-through
> *An Untrusted Ethernet port is not technically a DTE but for cabling purposes, should be treated as such. § Routers with uplink ports may behave in reverse.

> If all cables are connected correctly, the link light for each connection illuminates.
