Reading the LEDs

The tape drive uses three LEDs (Figure 2-1) to indicate its operating states.

The LEDs indicate the following general conditions:

•When the top (orange) LED is flashing, the tape drive has an error or needs cleaning.

•When the middle LED is on or flashing, SCSI bus activity is occurring. The middle LED can be orange or green as follows:

Orange	The tape loaded in the tape drive is in one of the
	compression formats (8500c or 8200c). When the tape is
	8500c format, the LED is always orange even though
	compression can be turned off.
Green	The tape loaded in the tape drive is in one of the
	non-compression formats (8500 or 8200).

•When the bottom (green) LED is on, a data cartridge is loaded in the tape drive. When this LED is flashing, the tape is moving or the tape drives needs cleaning.

Table 2-1 shows a specific combination of LEDs that may occur during tape drive operation and the tape drive states that they indicate.
