This chapter shows the locations and describes the functions of the:
• Library Storage Module (LSM) operator panel
• Cartridge drive operator panel inside the LSM
• Emergency power-off (EPO) switches
• Power switch for the Library Management Unit (LMU)
Use the LSM operator panel to monitor and execute the various operations
associated with the LSM.
Use the transport/tape drive operator panel on the inside of the LSM to perform
manual cartridge mounts and dismounts when the LSM is offline.
Use the LSM and cartridge subsystem
EPO switches, and the LMU power-off
switch, to immediately remove power from the units.
■ LSM Operator Panel
The LSM operator panel is beside the door of the LSM directly above the small
viewing window. The panel:
• Shows status and diagnostic information
• Shows number and location of cartridges in the Cartridge Access Ports
(CAPs) and the Priority Cartridge Access Port (PCAP)
• Contains LSM switches:
POWER, EPO, IPL, and RESET
• Displays LMU status information when the LMU is in the EM
The lower area of the panel displays LMU information. For LSMs with the 9312
Electronics Module (EM) attached, this area remains blank.
Figure 2-1 on page 2-2 shows the panel, and Table 2-1 on page 2-3 lists and
describes each numbered item.
