9360 Library Storage Module
1-4 Tenth Edition 9871
Pass-thru Port
When an ACS contains more than one LSM, the PTP connects a 9360 LSM to
another 9360 LSM, or to a 4410, 9310, or Extended Store LSM. When a request is
made to move a cartridge in one LSM to a drive or storage cell in another LSM,
the robot in the source LSM delivers the cartridge to the PTP. The PTP transfers
the cartridge to the receiving LSM. The robot in the receiving LSM removes the
cartridge from the PTP and delivers it to an available drive, storage cell, or to
another PTP.
The PTP can transfer one or two cartridges at a time.
The PTP is also used when the scratch tapes have been depleted in an LSM.
The PTP passes scratch tapes from an LSM with available tapes to an LSM that
has depleted its source of scratch tapes.
Figure 1-2 is a top view of two 9360 LSMs connected by a PTP. The figure
shows the location of the access door, CAPs, cartridge drives, and the 9315 and
9312 EMs, plus the arrangement of storage cells inside the LSM.
