[. . . ] The EEPROM parameter EnaCleanLib is used otherwise. 1 SCSI Cleaning Error Reporting 1 For HWE (Hard Write Error)/HRE (Hard Read Error) that are not related to servo problems, the Cleaning Requested ASC/ASCQ (00/17) status is reported using the same criteria as setting the TapeAlert Clean Now flag. The Cleaning Requested ASC/ ASCQ replaces the 0C/00 for HWE or the 11/00 for HRE. The Cleaning Requested ASC/ASCQ is only reported if the EEPROM parameter EnaCleanSense is set to 1. For more details, see the SDLT 600 SCSI Interface Guide (81-81200-xx). Front Panel Cleaning Light 1 The Cleaning Required (yellow) LED on the front panel indicates to the operator that cleaning is needed. The location of the Cleaning Required LED (and other front panel LEDs) is shown in figure 9. SDLT 600 Design and Integration Guide 26 Chapter 1 General Tape Drive Specifications Occasional Cleaning of Tape Head Figure 9 SDLT 600 Tape Drive Front Panel Cleaning LED Yellow LED (Cleaning Required) If EnaCleanLight is enabled, the yellow LED illuminates steadily for these conditions: · When a HWE (Hard Write Error)/HRE (Hard Read Error) is encountered · More than 100 hours of tape motion have occurred since the last cleaning. Once illuminated, the yellow LED remains illuminated until one of the following occurs: 1 Tape drive is cleaned successfully; 2 The tape drive is reset due to a firmware failure or firmware update, or 3 Power is cycled off and on. SDLT 600 Design and Integration Guide 27 Chapter 2 2Electrical Specifications This chapter provides the electrical specifications associated with the SDLT 600 tape drive, which includes the following two topics: · Current and Power Requirements · Power Supply Tolerances Current and Power Requirements 2 Table 23 lists the current and power requirements for the two versions of the SDLT 600 tape drive system (internal and tabletop) configured with the parallel SCSI interface. 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%. [. . . ] Several causes, including a defective data cartridge, may be causing the failure to load event. The data cartridge should be inspected after a failure to load or unload event. SDLT 600 Design and Integration Guide 83 Chapter 9 Insertion and Extraction Guidelines Applicable Library Commands Exception Conditions 9 The tape drive sets the Hardware Error bit in the event of hardware failure. Status Byte 3 will post a Hardware Error and Cartridge Present if there is a detected tape load or unload failure. The tape drive always attempts to recover from a hardware problem by resetting the servo processor. [. . . ]
