Cleaning Cartridges
3
In host-initiated cleaning mode the host tracks all cleaning
cartridges and their use.
In automatic cleaning mode the library tracks all cleaning
cartridges and their use.
Capacity
3
Although a maximum of ten cleaning cartridges may be present in
the P2000, four or less are recommended to optimize library
performance. If more than ten cleaning cartridges are present in
the library at inventory, the library moves the additional cartridges
to the load port for manual unloading.
Identification
3
Cleaning cartridges have unique bar code labels that begin with
“CLN,” (for example, CLN001).
Storage and
Tracking
3
Each cleaning cartridge is tracked from the time that it is loaded
into the library. When a cleaning cartridge is unloaded from the
library, the library no longer retains information concerning that
cleaning cartridge (bar code). If a new cleaning cartridge with the
identical bar code is then imported into the library, it is considered
a different cleaning cartridge for all tracking purposes.
Each cleaning cartridge must have a unique bar code. If a cleaning
cartridge with a duplicate bar code label is imported, the original
cleaning cartridge is moved to the load port for removal from the
library.
After a cleaning cartridge is used twenty times it is moved to the
load port for removal from the library.
The library adjusts for cleaning cartridges that are manually
moved within the library while the library is off-line. When an
inventory is performed (after power-up or a transition from off-
line to on-line), all cartridges are scanned and identified. Each
