Connecting Your Zip 250 SCSI Drive

The instructions in this section show how to connect your Zip drive to the built-in 25-pin SCSI port on a Mac^® or Mac-compatible computer.

G3 and G4 Users

To connect your Zip drive, you will need to first install a SCSI PCI Card. Contact your local reseller to purchase one.

PowerBook Users

If your PowerBook supports SCSI, you will need a special PowerBook cable (which you may already have) or an HID-SCSI adapter to connect the Zip drive to a PowerBook. If you do not have a Powerbook SCSI cable, you need to contact your local reseller.

iMac^™ Users

The iMac^™ computer does not have a PCI slot for a SCSI card. You need to purchase a Zip USB drive rather than a Zip SCSI drive to use your Zip disks.

1. If you have not already installed IomegaWare software, install it now.

2. Check the SCSI IDs and termination settings of existing devices.

   Go to step 3 if there are no other SCSI devices connected to your computer. If there are other devices connected verify the following:

   • SCSI ID 5 is not being used by those devices
   • Termination is set properly for all SCSI devices
   Instructions on how to check the SCSI ID and set the termination reside in the SCSI Guidelines. If another SCSI device is connected to your computer, complete steps 1-5 in the SCSI Guidelines section, before continuing to step 3.
   
   
3. Locate the necessary SCSI cable.
   
   If you are connecting to a 25-pin connector, continue with step 4. If you are connecting the Zip drive to a device that does not have 25-pin connector, you will need to purchase a different cable or connector. See the illustrated chart of available SCSI connectors and adapters that can be used to help connect your Zip drive. Before continuing with the next step, determine which cable may be needed in connecting your Zip drive. If you need to purchase a different cable, connector, or adapter, see Purchasing Iomega Products for more information.



4. Shut down your Mac^®, turn off all connected devices, and disconnect all electrical power.

CAUTION! Always turn off power to the computer and all devices connected to it (such as printers or drives) before beginning any computer hardware change.

5. Connect the end of the data cable marked "zip" to the Zip connector on the back of your Zip drive.

If the connector does not go on easily, try turning it over. Tighten all connector screws.

CAUTION! Never move the drive while a disk is inserted.

6. Connect the other end of the SCSI data cable to the 25-pin SCSI connection on your computer.








NOTE: If you are connecting your Zip drive to an existing SCSI chain, make sure the SCSI ID and termination are set correctly see Connecting Your Zip Drive to a SCSI Chain.






CAUTION: If you choose to connect your Zip drive to a Fast SCSI-2 or Ultra SCSI card rather than to a Mac standard SCSI connection, make sure that the Zip drive is always located at the end of the chain. The Zip does not operate at Fast SCSI or Ultra SCSI speeds but it should not slow the performance of other devices if it is connected at the end of the chain.

7. Connect the external power supply and turn on the power switch.
   
   

   

   
   Check that the green activity light on the Zip drive flashes briefly. The green activity light on the Zip drive flashes as the disk spins up, or when it is busy, and glows steadily while it acquires data. When the light goes out, the drive is ready to use. If the green activity light does not flash, refer to Troubleshooting.

CAUTION! Use only an approved Iomega Zip power supply. Other power supplies may damage your Zip drive.

8. Restart your computer.


9. Insert a Zip disk and the Zip drive is ready to use. You should see the Zip disk (or drive) icon on your desktop.
   
   If the appropriate icon does not appear, see the Iomega Web Support Site at http://www.iomega.com/support or refer to the Troubleshooting on the User's Manual CD.

• For information on operating your new Zip drive, refer to Using Your Zip Drive.



• See Using IomegaWare Software for information on the software that came with your drive.



• If you encounter problems installing or using the Zip drive, refer to Troubleshooting.

Connecting Your Zip Drive to a PC

The instructions in this section show you how to connect your Zip drive to a SCSI card that has been installed in your PC.

• If you plan to use an Iomega SCSI card such as the Zip Zoom PCI SCSI Card, see Purchasing Iomega Products.


• If you plan to use a non-Iomega SCSI card, refer to Non-Iomega SCSI Cards in the "SCSI Guidelines."

1. If you have not already installed the IomegaWare software, install it now.


2. Check that your PC has a SCSI card installed.





SCSI Adapter (installed inside the computer) Back of computer SCSI Connector (from SCSI adapter)




Your PC must have a SCSI card installed. If your computer does not already have a SCSI card installed, one will have to be installed. Purchase a Zip Zoom SCSI card (see Purchasing Iomega Products) and follow the included instructions to install it.

If you choose to connect the Zip drive using an alternative method, the following instructions in this section will not apply. See the documentation that shipped with the adapter for instructions on connecting it to your Zip drive and PC.

Windows NT^® 4.0 users—you will need to install driver software for the new SCSI adapter. Refer to Troubleshooting for more information.

3. Check the SCSI IDs and termination settings of existing devices.

   Go to step 4 if there are no other SCSI devices connected to your computer. If there are other devices connected verify the following:

   • SCSI ID 5 is not being used by those devices
   • Termination is set properly for all SCSI devices
   Instructions on how to check the SCSI ID and set the termination reside in the SCSI Guidelines. If another SCSI device is connected to your computer, complete steps 1-5 in the SCSI Guidelines section, before continuing to step 4.

4. Shut down your PC, turn off all connected devices, and disconnect all electrical power.




CAUTION! Always turn off power to the computer and all devices connected to it (such as printers or drives) before beginning any computer hardware change.

5. Connect the end of the data cable marked "zip" to the Zip connector on the back of your Zip drive. If the connector does not seem to fit, try turning over. Tighten all connector screws




CAUTION! Never move the drive while a disk is inserted.



6. Connect the other end of the data cable to the SCSI connection on your computer.




You will need a different cable or a cable converter only if you are connecting the Zip drive to a SCSI device that does not have a 25-pin connector. See the necessary SCSI cable and converter chart for the available types of cables and connectors for the Zip drive.



IMPORTANT: Make sure you connect the Zip cable to a SCSI connector and NOT to a parallel (printer) port. The parallel port is the same size and shape as some of SCSI adapter connectors, but the parallel port will not support this model of the Zip drive.

NOTE: If you are connecting your Zip drive to an existing SCSI chain, make sure the SCSI ID and termination are set correctly.










CAUTION: If you choose to connect your Zip drive to a Fast SCSI-2 or Ultra SCSI card rather than to a Zip Zoom PCI SCSI connection, make sure that the Zip drive is always located at the end of the chain. The Zip does not operate at Fast SCSI or Ultra SCSI speeds but it should not slow the performance of other devices if it is connected at the end of the chain.

8. Check that the green activity light on the Zip drive flashes briefly. The green activity light on the Zip drive flashes as the disk spins up, or when it is busy, and glows steadily while it acquires. When the light goes out, the drive is ready to use. If the green activity light does not flash, refer to Troubleshooting.
