Figure 2 shows the location of dip switches on the underside of the internal Scorpion 240. Each of these switches is described in detail on subsequent pages.

Note. Power down the drive before changing jumpers or dip switches. Changes take effect when the drive restarts.

Data compression (switches 1 and 2)

If switch 1 is ON (the default setting), hardware data compression is enabled when the drive is powered on. If switch 1 is OFF, hardware data compression is disabled at power-on.

If dip switch 2 is ON (the default setting) then SCSI commands can be used to enable or disable hardware data compression. To prevent hardware data compression from being enabled or disabled by SCSI commands, set dip switch 2 to OFF.

Media-recognition system (switch 3)

The media-recognition system allows the drive to determine whether a given tape cartridge conforms to the DDS tape standard. Use of non-DDS media may appear to give
