The PSMs operate in parallel, sharing the load. This reduces the stress on the individual power supplies and greatly extends their service life. When the N+1 option is installed, the library will continue to operate if one module fails. The remaining PSMs will power the RLS-8500 indefinitely. The library 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 PSM is operating properly. A failed PSM causes an alarm condition that will result in e-mail notification by the Q-Link remote library manager. 2-6 Product Description 511001 Rev. A All PSMs supply regulated 24-volts DC to the RLS-8500. The unit is powered from AC mains of 100- to 240-volts, 50 or 60 Hertz.

A Product Description 2-7 2. 5. 4. 1 Storage Slots Each RLS-8500 model utilizes a left and right fixed matrix of storage slots (up to 60 cartridges on the right side and 54 on the left). The storage matrices may be removed from the unit for bulk loading or removal of cartridges. Figure 2-6 Left Storage Matrix Extended 2. 5. 4. 2 Tape Drives The RLS-8500 Series library accommodates up to five tape drives. The drives are housed in plug-in drive carriers that may be installed or removed while the other drives within the unit 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. This information is immediately uploaded to the executive processor and is available to the host computer whenever a new drive is plugged-in. The drive's world-wide name is set to the RLS menu values as soon as power is applied. Any tape drive may be inserted or removed while the others are running. A drive can be changed within a minute and no tools are required. Blank filler panels must be installed at each vacant tape drive location.

A 2. 5. 4. 3 Robotics The RLS-8500 utilizes a four-axis robotic cartridge handling system that moves cartridges between the storage slots and the tape drives. All axes are driven by brushless DC motors. The motors move the linear axes with precision lead screws driven by long-life timing belts.
