1-4 Introduction
Chapter 2 Installing the EN/SC Adapters This chapter provides step-by-step instructions for installing Asante EN/SC and Mini EN/SC adapters and Asante EtherTalk Installer. Please make sure you have prepared for the installation by completing each step described in this chapter. The EN/SC adapter can be the only SCSI device you connect to the Macintosh or it can be one of several devices in a SCSI daisy-chain. The installation procedure for both configurations is described in this chapter.
Preparing for the Installation Before installing the Asante EN/SC adapter, make sure you have the following: Software: An AFP-compliant network operating system and applica- tion software to run on the network Apple System Software 6.0.7 or higher • Asante EtherTalk 5.1 Installer or higher Hardware: SCSI Cable The appropriate EN/SC Adapter for your computer If you have a PowerBook and use the EN/SC PB Adapter or the Mini EN/SC Adapter both have the correct cable and termination option.

It is important to identify the Ethernet type being used in your network, the connection and termination requirements. Each type of your Ethernet cable, must meet certain IEEE Ethernet length specifications. Please refer to Appendix B for detailed information on IEEE Ethernet length specifications.
Observing the safety rules Observe the following safety precautions during the installation: • Consult your network administrator about the EN/SC adapter installation and its effect on the network. Do not disrupt the network before informing your network administrator. Other users must be warned of the possible interruption of network operations. Prior to connecting and configuring the EN/SC, turn off the Macintosh and all peripherals connected to it.
Set adapter's SCSI address When you add a SCSI device to a Macintosh it must have a unique SCSI address between 1 and 6. A "0" address is usually reserved for the Macintosh internal hard drive. Be careful not to duplicate the SCSI address of any other SCSI device in the SCSI daisy-chain. • On the Mini EN/SC adapters set the SCSI address using the rotary switch on the bottom.
Determine SCSI termination Follow these simple rules and use the table to determine where you need to provide SCSI termination. • In a SCSI chain the first and last device in the chain must be terminated with no termination in between. • Termination is either internal or external. External termination requires a termination block. The first device is always the Macintosh, which is terminated internally.

Make sure all devices are turned off. Using the rotary switch, on the rear of the EN/SCAdapter or on the bottom of the Mini EN/SC Adapter, set the adapter's SCSI address. You can use any address between 1 and 6 (0 is reserved for the Macintosh hard drive) .
DB-25/DB-25-to-HDI-30 cable for the PowerBook (with DB-25/DB-25 "T" side connected to Mini) After connecting the Mini EN/SC to the Macintosh or PowerBook, connect it to the other SCSI device using the appropriate SCSI cable. If the Mini EN/SC is the last device, connect it to the SCSI device using the appropriate cable . •:. Note: When connecting the Powerbook to the first device in the SCSI chain you can use the (the DB-25-toHDI-30).
If you have a bus topology and if the Macintosh is the first node or last node, terminate one end of the "T" connector using a 50-ohm BNC terminator. Move the switch on the front of the EN/SC adapter to TN. With Thick coaxial cabling (EN/SC and EN/SC PB only) Connect a transceiver to the Thick Ethernet cable: Plug one end of the thick Ethernet drop cable into the AUI port on the EN/SC adapter. Plug the other end of the thick Ethernet drop cable into the Thick Ethernet backbone tap.
Installing the EtherTalk software An EtherTalk Installer diskette is included with each Asante EN/SC adapter. This diskette contains Asante's EtherTalk driver, AppleTalk., and other Apple system extensions. Asante's EtherTalk device driver allows AppleTalk to communicate with the EN/SC adapter. 1\vo types of software installations Asante provides two types of installations-an easy install and a customize install.

• When subdividing cable segments, do not randomly pick any length of cable. The IEEE recommends that Ethernet coaxial cable be subdivided at lengths of 23.4 meters (76.8 feet), or multiples of that length, in order to minimize internal signal reflections. Using less than 10 ft. of cable between devices causes reflections. These reflections reduce the signal strength for large networks. On small networks, such as those covering a single floor of a building, these reflections probably won't cause problems.
