Insert each cartridge into a slot of the magazine making sure that the write-protect switch is toward the top, facing the closed side of the magazine (as illustrated).

The cartridges can fall out once the cover has been removed. The open side of the magazine faces the VLS. Most labels use a removable adhesive and have a tendency to curl or tear after multiple uses. Note the following: p p Store magazines (and data cartridges) in a dry, cool environment. Never reset or power down your computer or VLS unit while a function is in process or a tape is moving. In addition to a tape with missing or corrupted data, you may also get tape run-on within the drive (a condition that can produce internal contamination requiring extra cleaning). If a power outage occurs during a back-up sequence, restart your backup from the beginning. p Inserting the Magazine into the VLS Warning Due to static the label or other items included in this package will occasionally cling to the DLT cartridge. Before loading into a drive, ensure that all other items from this package are separated from the cartridge. Operation and Maintenance 31 í Do not attempt to place a covered magazine onto the VLS carriage. p Remove the magazine dust cover. You can remove the cover by pressing the middle of both ends (where it is labeled PUSH) and lifting up (see Figure 9). (The pick arm must be in the "out" position before you try inserting a magazine. ) Holding the magazine by the handle, and at a 45º angle to the carriage, slip the magazine onto the left side of the carriage, over the left magazine position pin (see Figure 11). p p Left Magazine Position Pin Figure 11. Placing the Magazine onto the VLS Push the right side of the magazine over the right magazine position pin until you hear a click. See Figure 12. 32 Operation and Maintenance í You may need to apply downward pressure as you slip the magazine over the right magazine pin and then press the magazine into place with your index finger. Figure 12. If you don't hear a click, make sure that the slot on the right side of the magazine has slipped around the right magazine position pin and is not just sitting on top of it (the magazine will not load correctly in this position). Loading the Magazine Once you have placed the magazine on the carriage, the VLS must initiate a loading process. During this procedure the VLS checks and maps the position of each cartridge and makes sure that all cartridges are inserted into the magazine correctly. If you are using the sequential mode the VLS inserts the first cartridge into the drive. í The door must be closed before the LOAD or UNLOAD functions will activate. p p Make sure the magazine is placed correctly on the carriage. Note In the sequential mode, if you press UNLOAD before the VLS has finished loading the magazine, the robotics will finish mapping and checking the cartridges and then move the magazine to the unload position (the far right) without inserting a cartridge into the drive. Operation and Maintenance 33 In random mode, if the VLS has not finished loading the magazine, pressing UNLOAD will have no effect. Attempting to Load the Magazine with a Cartridge Already in Drive If your VLS is equipped with firmware version 2. 31 or earlier, refer to Appendix C. Random Mode: If the cartridge was loaded manually, it must be unloaded manually ­ before you attempt to have the VLS load the magazine. If the VLS robotics was used to load the cartridge via applications software, attempting to "load magazine" from the keyboard will fail ­ the unit will remain On-Line. Sequential Mode: If the cartridge was loaded manually, it must be unloaded manually ­ before you attempt to have the VLS load the magazine. If the VLS robotics was used to load the cartridge, the VLS will remember and not allow a "load magazine" from the keyboard.
