Reading the LEDs
The tape drive uses three LEDs to indicate its operating states. The LEDs indicate the following general conditions:
■
■
When the top (amber) LED is flashing, the tape drive has an error or needs to be cleaned.
When the middle LED is on or flashing, SCSI bus activity is occurring. The middle LED can be green or amber, as follows:
Amber: The tape loaded in the tape drive is in one of the compression formats (8500c or 8200c). Note that when the tape is in 8500c format, the LED is always amber even though compression can be turned off.
Green: The tape loaded in the tape drive is in one of the
■When the bottom (green) LED is on, a data cartridge is loaded in the tape drive. When this LED is flashing, tape motion is occurring.
Table 2 shows specific combinations of LEDs that may occur during tape drive operation.
Note: You may occasionally observe LED combinations and sequences not described in Table 2. These other combinations represent special or unusual conditions that are beyond the scope of this table. (For example, a fairly complex LED sequence occurs when you load new microcode from tape.)
