[. . . ] Table 24 on page 31 lists the current and power requirements for the internal version of the SDLT 600 tape drive system configured with the Fibre Channel interface. The library version of the SDLT 600 tape drive uses the same amount of power as the internal version with both the SCSI and Fibre Channel interfaces. The tape drive draws the highest current (and power) during the native write modes. Standby is measured with the tape loaded and tensioned or untensioned, and Idle is measured with power on with no tape loaded. SDLT 600 Design and Integration Guide 28 Chapter 2 Electrical Specifications Current and Power Requirements (The power drawn in these two modes is similar enough that they are listed together. ) Note: In table 23 and table 24, the current and DC power values pertain to the internal tape drive, while the AC power values apply to the tabletop tape drive.

On the 12V supply, the peaks correspond to the pulse-width-modulated switching of the motors. These values are calculated from the average of Peak-ripple-current + 2 sigma, measured at nominal DC voltage. The Max-Mean value is the average of the maximum RMS current drawn during this operating mode. These values are calculated from the average of RMS current + 3 sigma, measured at nominal DC voltage. The typical current is calculated from the average of all RMS current drawn during this operating mode, measured at nominal DC voltage. The Max DC power is calculated from the typical DC power + 3 sigma, measured at nominal DC voltage. This value takes into account that the peak currents on the 5V and 12V do not occur at the same time. The Typical DC power is calculated from the average RMS DC power drawn during this operating mode, measured at nominal DC voltage. This value also takes into account that the peak currents on the 5V and 12V do not occur at the same time. The Max AC power is calculated from the typical AC power in tabletop tape drives + 3 sigma. The Typical AC power is calculated from the average of AC power drawn in tabletop tape drives. These events last < 1 second and occur at a duty cycle of less than 25%. The Max values for each mode are based on the Max-Mean values, since the peak values are of very short duration. Voltage tolerance: 5V ±5%, 12V ±5%; Room temperature 24 °C. DC Current, MaxMean, and DC/AC Power Max refer to the statistically calculated maximum average requirement based on a sample population of tape drives. These values do not reflect the peak current or power requirement; this amount is given by the DC MaxPk current. 2. 3. 2.

Realistic Expectations 9 The SDLT 600 tape drive should typically complete the reset and recovery process in less than 3 minutes, although it is possible that heroic (extensive) data recovery retries--in some cases--can take longer. The servo processor can be reset three times during error recovery, with each reset lasting approximately one minute. The amount of tape that has to be rewound into the data cartridge affects recovery time, but a tape drive that has not successfully recovered from its error state in several minutes requires manual intervention. The data cartridge should be inspected after a failure to load or unload event.
