Cartridge Access Port (Cap); Cartridge Subsystem - StorageTek 4410 Hardware Operator's Manual

4. The robot retrieves the cartridge from the cell.
5. The robot moves to the specified transport and mounts the cartridge.
When a dismount is requested, the robot removes the cartridge from the transport and
does one of the following:
• Returns the cartridge to the source cell if pass-thru operations were not required to
mount the volume.
• Places the cartridge in an available cell in the robot LSM if pass-thru operations were
required to mount the volume. (Normally, pass-thru operations are not performed to
place a cartridge in a storage cell after it has been dismounted, as long as an available
cell exists in the LSM.)
• If specifically directed to return the cartridge to its original home cell location, the
robot places the cartridge into the PTP/CEM cell to begin passing it back to the
original LSM.
Each LSM has an access door in the outer wall for human access to the interior. The
access door contains at least one CAP and might contain a PCAP.

Cartridge Access Port (CAP)

The CAP and PCAP allow you to enter and eject cartridges without interrupting
automated operations in the LSM. The standard 21-cell CAP allows up to 21 cartridges to
be loaded into or removed from the LSM without your having to enter the LSM.
The enhanced 80-cell CAP allows up to 80 cartridges to be loaded into or removed from
the LSM without your having to enter the LSM. This CAP consists of two doors, which
hold 40 cartridges each, and a PCAP. You can also place the cartridges in magazines that
hold 10 cartridges each, and place the entire magazine in the CAP. The PCAP allows one
cartridge to be entered or ejected.

Cartridge Subsystem

The cartridge subsystem consists of:
• 4xxx cartridge drives (CDs) that attach to the LSM, and control units (CUs). The CD
contains two or four transports, into which tape cartridges are placed for read or
write operations. The CU is the controller/interface between the CDs and input/
output channels. 4xxx transports require 3480-type cartridges.
• 9490 cartridge drives (CDs) that attach to the LSM and contain two or four
controller transport units (CTUs). Each CTU has a transport. 9490 transports require
3480-type cartridges.
• SD-3 cartridge drives (CDs) that attach to the LSM and contain one to four
controller transport units (CTUs). Each CTU has a transport. SD-3 transports require
helical scan cartridges.
