148 StreamLine™ SL8500 Modular Library System User's Guide • March 2007 Revision K • 96154
service safety doorA motor-driven barrier that separates the service areas of the customer interface
module from the rest of the library so that service personnel can safely repair or
replace failed library mechanisms while the library continues normal operations.
Synonymous with safety barrier.
servo power interrupt
A signal that removes voltage to a motor if overtravel is detected in the motor or
a safety condition exists (for example, the main access door to the library storage
module is open). When the sensor or switch is made, the drive current to the
motor disables and an error posts. The SPI prevents a servo runaway condition for
an out-of-range motor; it also prevents motors from starting up while the access
door is open.

SL8500 addressA five-digit, comma-separated value (L,C,R,S,W) that represents Library, Rail,
Column, Side, and Row. This addressing scheme is used by SL8500 firmware and
internal communications to represent all devices and locations within the library.
SL8500 drive bayA two-digit integer
(01–64) that represents the physical locations into which drive tray assemblies are
inserted.
slotThe location in the library in which a cartridge is stored. Synonymous with cell.
SMCSee Storage Management Component.
SPISee servo power interrupt.
SSiSystem server infrastructure.
standby (pass-thru port)The side of a pass-thru port (PTP) that operates in response to actions initiated by
the master side of the PTP. See also master (pass-thru port).
storage cellSee slot.
storage expansion
moduleAn optional module for the Product Name library that provides up to 1728
additional cartridge storage slots. Up to three modules can be attached to each
SL8500 library.
Storage Management
Component (SMC)The software interface between IBM’s OS/390 and z/OS operating systems and
StorageTek real and virtual hardware. SMC performs the allocation processing,
message handling, and SMS processing for the NCS solution. It resides on the
MVS host system with HSC and/or MVS/CSC, and communicates with these
products to determine policies, volume locations, and drive ownership. SMC is a
required NCS component.
