This reduces the stress on the power supplies and greatly extends their MTBF (Mean Time Between Failure). The two PSMs are identical and either one is capable or running the RLS on its own. The RLS and tape drives will continue to function, uninterrupted by the failure and subsequent replacement of the failed PSM. A green Power Good LED indicates that a half-sized PSM is operating properly. Each PSM has its own power cord and it is recommended that these be connected to different AC power sources to enhance overall system availability. A failed PSM or power source causes an alarm condition that can result in e-mail notification by the Q-Link remote library manager. Each half-sized PSM contains a fan and full-sized 250-watt PSMs have two fans. A failed fan also causes an alarm condition that can result in e-mail notification with the Q-Link remote library manager. 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.

[. . . ] Qualstar Tape Libraries fall under the category of "Information Technology Storage Array Systems" for which the RoHS Directive provides for a lead solder exemption until the year 2010. Insofar as lead free solders are new to the electronics industry and no quality or reliability data is available, Qualstar invokes the lead based solder exemption until such time as industry data verifies that lead free solders are capable of meeting or exceeding the documented reliability and quality standards achieved with lead based solders. Until such time as Qualstar replaces lead based solder with lead free solder, effected subassemblies must be disposed of appropriately. 501490 Rev. Q Agency Compliance 5-3 6.
