94 Front Panel LEDs
Other LED Patterns
There are other patterns usually involving several LEDs, which have the
following meanings:
Flashing An unrecoverable hardware failure has occurred. A power cycle or
successful tape load will turn the LED off, but the LED will start flashing
again if the same operation is performed and the hardware fault is still
present
Tape Error The third LED is orange and indicates a problem with the tape:
Off No fault has been detected.
Flashing The drive thinks the tape currently in the drive is faulty. The LED could flash
for a number of reasons, but they all relate to the tape being in error in
some way, such as unreadable cartridge memory or unsupported tape. Do
not use the cartridge; replace it. The LED will go out when a tape load is
started.
Clean The bottom LED is orange and indicates if the drive needs cleaning.
Off The drive does not require cleaning.
Lit steadily A cleaning cartridge is being used. the Ready LED will flash.
Flashing The drive needs cleaning. The LED will continue to flash if the drive is power
cycled, and will only go out after a supported cleaning tape has been used.

Cause Action required
All LEDs OFF.
Drive may not have power
or may be faulty. This
pattern occurs just after the
drive has been switched on
or reset.
Make sure the drive is switched on. The power on/off switch
incorporates a green LED.
If this is not on, check the power cable connection and
replace the cable if necessary. 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, press
emergency reset or power cycle the drive. If it still fails, call
for service.
