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 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, 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.)
