Operation 2-27 Inserting and Removing Cartridges When inserting cartridges, be sure that the slot you intend to use is not already reserved in the system map for a cartridge in a drive. The best way to avoid conflicts is to unload all drives, either through your host computer software or by using the Load/Unload command on the Main Menu, described in the previous section. The tape magazine must be removed from the module in order to insert or remove cartridges. To insert or remove the magazine, the following conditions must be met. The Magazine Security Lock (Figure 2-34) must be unlocked, using the key supplied with the module. When the Magazine Security Lock is locked, the Unlock/Open button has no effect. If the module is installed in a reasonably secure environment, you may elect to leave the Magazine Security Lock in the unlocked position. Media locking on the Security Menu must be disabled. See Figure 2-20. The host computer must allow medium removal. The host computer can enable or disable the Unlock/Open button using the SCSI Prevent Allow Medium Removal command. When you press the Unlock/Open button, the message 'Magazine Locked" will be displayed. The Expansion Unit must be ready, and not actually executing a command. IMPORTANT: When you enter the Menu Mode, the Ready light goes out. The magazine cannot be inserted or removed unless the Ready light is on. To remove the magazine when a failure prevents the Ready light from illuminating, refer to the section entitled Emergency Magazine Removal.
