[. . . ] With dual PSMs, both fans continue to run even when a PSM fails. 2. 5. 4. 2 Interface Personality Module (IPM) The IPM is a plug-in module that can be changed when the RLS is powered-down. It always contains the SCSI connectors to the RLS medium changer and an RS-232 serial port that can be used for remote management. 501490 Rev. Q Product Description 2-7 The standard medium changer interface is LVD/SE (Multi-mode) SCSI and includes the Q-Link remote library manager. Q-Link provides a 10BaseT half-duplex connection to LANs and the Internet. An optional two-gigabit per second (2Gb) Fibre Channel to SCSI Bridge IPM is available. This IPM connects the medium changer to a single, 2Gb/second Fibre Channel port. The Q-Link Remote library manager is also standard on this IPM. 2. 5. 4. 3 Tape Drive SCSI Interface Panel There is a pair of HD-68 SCSI connectors provided on the Interface Panel for each tape drive, even if a drive is not installed. The standard SCSI interface is a loop, from one of these connectors to the tape drive's SCSI connector and back to the other connector. This scheme provides for quick drive changes without unplugging the SCSI cables attached to the interface panel. However, when a tape drive is removed, the connection between the pair of SCSI connectors on the interface panel is broken. Thus, unplugging a tape drive on a live system may cause the SCSI bus to hang. 2. 5. 4. 4 Tape Drive DFA (Direct Fibre Attach) Interface Panel On the RLS-8204D, 8236D, 8244D, 8404D and 8444D models there is a fibre channel connector provided on the Interface Panel for each DFA tape drive. 2. 5. 4. 5 Tape Drive SAS (Serial Attached SCSI) Interface Panel When SAS tape drives are ordered on the RLS-8236, 8204, 8244, 8404 or 8444 models there is a SAS connector provided on the Interface Panel for each SAS tape drive. 2-8 Product Description 501490 Rev.

Q Product Description 2-9 2. 5. 5. 1 Magazines A magazine is a multi-compartment container that can hold four tape cartridges. A magazine and its cartridges can be removed from the RLS as a unit. Magazines self-lock on their mounts and are easily removed by pressing a release button. Additionally, each cartridge is individually retained within the magazine to prevent mishandling or damage. 2. 5. 5. 2 Storage Array All models utilize a patented storage array that holds 9 or 11 magazines in a rectangular array. The magazines move around the racetrack-like array in either direction. The direction of movement is chosen to minimize the time to access the desired magazine. Storage arrays employ a high-reliability mechanism that utilizes a single brushless DC motor. If no power is available, a blade screwdriver can be inserted through a hole in the bottom of the RLS to manually move the storage array in either direction.

The drives are housed in plug-in drive carriers that may be installed or removed while the other drives within the RLS are operating. A microprocessor in the drive carrier communicates with the tape drive via its supervisory port to ascertain its model, serial number and operational status.
