[. . . ] In systems that support "failover, " both ports can be connected through separate loops or fabrics to the same set of host computers. This way, if one connection fails, the other can be used to continue the data transfer. Fibre channel optical connector Figure 10. Rear view of the Viper 200 FC internal drive showing fibre channel optical connectors Connecting a Serial Interface Cable (for tape libraries) The Viper 200 drive includes an RS-422 serial interface for tape libraries. The RS422 serial interface connector is on the top of the extension on the back of the drive, as shown in Figure 11. 26 Viper 200 LTO Product Manual Serial Interface connector pin numbers BA 17 15 13 11 9 7 5 3 1 18 16 14 12 10 8 6 4 2 Pin Numbers (Pin 17 removed to prevent connector from being attached incorrectly) Figure 11.

Figure 7 on page 23 shows the location of the power connector on Viper Fibre Channel drives. The recommended 4-pin power connector for the internal Viper 200 is an AMP 148024-0 housing with AMP 60617-1 pins or equivalent. Installation 27 Installing an external Viper drive The external Viper 200 drives (STU62001LW and STU62001WD) are compact subsystems that connect to the host computer through an external SCSI port. Installing an external drive involves the three simple steps shown below: 1. Configuring an external drive Setting the SCSI ID Make sure that the drive is turned off. Then set the SCSI ID for the drive using the push-button switch on the back of the external drive, as shown in Figure 12. The change will take effect when you turn the drive back on. SCSI ID selector 68-pin wide SCSI connectors + ­ On/Off switch AC Power connector Figure 12. Connecting the SCSI interface cable The external Viper 200 provides two 68-pin, shielded connectors (ANSI Alternative 2) on the rear panel of the enclosure (see Figure 12). These connectors consist of two rows of ribbon contacts spaced 2. 16 mm (0. 085 in) apart. Either connector can be used as a SCSI IN or SCSI OUT connection, so you can use either connector to attach the drive to a host computer or to another SCSI device. Note: Turn off all power before connecting or disconnecting SCSI cables. 28 Viper 200 LTO Product Manual SCSI termination If the Viper drive is the last device or the only device in a SCSI chain, you must install a terminating plug on the unused SCSI connector. You can purchase appropriate terminating plugs on the Internet at http://buytape. seagate. com. Termination power is enabled as a default for the external Viper 200 drive. External SCSI device SCSI Terminators External Tape Drive External Tape Drive External SCSI device SCSI Controller (termination disabled) SCSI Controller (termination enabled) Internal SCSI device (termination enabled) Example 1: SCSI termination in a system that has only external SCSI devices. Example 2: SCSI termination in a system that has both internal and external SCSI devices. Figure 13. Connecting the power cord Attach the power cord securely to the power connector on the back of the drive (see Figure 12 on the previous page). Operation and maintenance 29 Operation and maintenance 4 This section describes important operational procedures for the Viper 200 drive. It covers the following topics: · · · · Understanding the front panel display How to use LTO cartridges Cleaning the tape drive "Parking" the drive for shipping, resetting the drive, and emergency cartridge removal Front panel display Multiple front panels are available for the Viper 200. Different panels are available for different customers, as well as for different operating environments (including automated systems). A generalized view of the Viper 200 front-panel display is shown in Figure 14.

[. . . ] Despite its ultra-high capacity, the Ultrium cartridge is thinner than other existing single-reel cartridges. It measures about 4 inches square and is a little more than 3/4 of an inch thick. The cartridge features a write-protect switch and built-in cartridge memory (described below). As shown in Figure 25, there is a door near one corner of the cartridge. [. . . ]
