If your drive does not have jumpers, then you have purchased a more recent model of our external drive (most likely after September 2004) in which a small switch is present under the larger power switch. If this is the case, please refer to the FAQ question. I see two switches at the back of my portable external drive, how do I use these?

Only proceed further in using this FAQ if you DO have jumpers as shown above.

The jumpers are used to switch the drive from Cable Mode to Docking Bay Mode, or vice versa. Cable Mode is used only when the drive is connected to a host via Olixir’s USB 2.0, Firewire, or Serial ATA cable. Docking bay mode is used only when the drive is plugged into Olixir’s 5.25 inch docking bay or a chassis. You must have the external drive jumper’s correctly configured for the interface you are using to ensure proper operation of the drive.

You can interchange external drive operation between docking bay and cable bay mode if you switch jumpers. Make sure the power switch is turned off before making jumper changes.

Here are the correct jumper settings for each mode (use tweezers to change the jumpers):

Cable Mode:Use when using the external drive with Olixir’s USB 2.0, Firewire, or Serial-ATA cable. You must also have the power supply connected to the power supply connector at the back of the drive (see above figure for the location of this connector).

The settings for Cable Mode vary based on which model of Olixir’s external hard drive you are using. Please see the label on the bottom of your product to determine correct model. Incorrect jumper settings will prevent drive from being operable, so please take care in ensuring the correct model’s jumper setting is used:

The drive is operational when the power switch is to the right (towards the red bumper). The drive is off when the power switch is to the left. If the drive is not operating properly, make sure cables are properly and securely connected. Please refer to the instruction manual for the drive to ensure that the proper order is used for connecting cables and turning on the drive.

Docking Bay Mode

Use when using the external drive with a chassis or 5.25 inch docking bay.

The drive is operational when the power switch (see Figure 1 above) is to the left (away from the bumper).

Purpose of Jumpers (for your information)

The jumper setting controls where the external drive derives power from. When the drive is used with USB 2.0, Firewire, or Serial-ATA cables, the external drive must derive its power via the power supply connector at the back of the drive (see below). When in Docking Bay Mode, the external drive must derive its power via the docking bay/chassis connection to the drive. The jumpers control the electronics internally to ensure the external drive derives its power from the appropriate source depending on which mode the drive is in.
