Table 7 LED sequences
LED Sequence Cause Action required
All LEDs OFF.
Drive may not have power,
may be faulty or may have
been power cycled or reset
during a firmware upgrade.
Make sure the drive is switched on.The
power on/off switch on an external drive
incorporates a green LED.
Check the power cable connection and
replace the cable if necessary. On external
drives, you can use the power cable from
your monitor or another device to check that
the connection is working.
If the power supply is present and all LEDs
remain off, power cycle or reset the drive (see
“ Problems with cartridges ” on page 64). If
it still fails, call for service.
