LED Name Status Indicator Description
Power (green) Off Power is off.
Flashing Unit is not functional (powering on, resetting 
the tape drive by performing an IPL, or 
collecting dump).
Flashing doesn’t stop: IPL failed.
Constantly on Power on and IPL have executed properly.
Activity (green) Off Cartridge is not loaded or ejected.
Flashing Tape motion is in progress.
Constantly ON Tape loaded, and the tape drive is ready; unit 
is operational.
Clean (Amber) Constantly ON Tape drive requires cleaning.
Indicator activated for 
one of these reasons:
Certain intermittent media errors were 
detected
A preset length of tape passed over the 
read/write heads.
Service (Red) Off No error was detected.
Flashing An error was detected, and dump data has 
been collected to EEPROM. Following a 
successful IPL, display alternates between a 
corporate “XXXX:DMP x”
Where XXXX = FSC, and x = number of 
uncollected dumps in EEPROM. Optionally, 
insert dump-formatted tape to copy data to the 
tape. The operator can ignore a flashing 
indicator. Flashing stops and messages are 
removed when any tape is inserted or any 
control is pressed. If within one minute the 
tape drive detects the same FSC, the 
message “DumpAgain?” is displayed: refer to 
DumpAgain? Message
 on page A-3 for 
instructions.
Constantly ON A hardware error was detected and tape drive 
is not functional. The operator cannot ignore a 
constant indicator. If resetting the tape drive by 
performing an IPL does not eliminate the 
problem, contact your service provider to 
replace the tape drive.
