Dell PowerVault TL4000 - Manual (Page 120)

Note: The universal cleaning cartridge has a bar code CLNUxxLx. This cleaning
cartridge is used to clean all LTO generation tape drives.
For Auto Clean to function, the following criteria must be met:
– On 4U libraries with library firmware of .80 or lower that still contain a
Dedicated Cleaning Slot (DCS), or 4U libraries with library firmware higher
than 1.95 that chose to retain the DCS in their library, a CLN cartridge must
be present in that slot.
– On libraries that don't have a DCS, a storage slot must be reserved (RSVD) by
reducing the active slot count by one.
– A cleaning cartridge (CLNxxxLx) must be placed or moved to the reserved
slot.
– Auto Clean must be enabled.
Note: Cleaning cartridges must be replaced after 50 cleanings. The Web User
Interface inventory screen will show the number of times the media has
been loaded, not the number of cleaning sessions remaining. Subtract this
number from 50 to determine the number of cleanings remaining.
v I/O Station(s) enabled - The I/O Station(s) can be enabled (the default), or
disabled so the stations can be utilized as storage slots.
v Remove DCS - If the DCS has been removed, it cannot be reinstated. This
option will no longer appear in the Operator Control Panel.
v Host Label Length - The Host Label Length is related to the Bar Code Labels
appearing on the media being used. The default value is 8, but 6 can also be
chosen.
