C HAPTER 4 Thermal Specifications 4.1 Over Temperature Condition This chapter presents the results of extensive experimentation and measurements of drive temperatures, and the resultant impact on SDLT 220/320 drive performance. An Overtemp condition is defined to be when the calculated Tape Path Temp = 52 degrees C. At that point, the tape is rewound, unloaded, and ejected if not in a library. If the drive is in a library, the tape does not eject.
CHAPTER 4: Thermal Specifications SDLT 220 and SDLT 320 Design & Integration Guide If a SCSI command is aborted as a result of the over-temperature condition, the drive returns status of: Hardware Error, Warning — Specified Temperature Exceeded (04h, 0Bh, 01h). 4.2 Air Flow Measurements Air flow is measured in the location shown in Figure 4-1. At the specified location, the air flow needs to be at least 125 LFM (linear feet per minute). Alternatively stated, the air flow needs to be at least 7.

Quantum provides two versions, namely: • LVD (50-84004-01) • HVD (50-84008-01) The longest recorded stub lengths on the latest version of each style of PCB are listed in Table 6-3. Table 6-3.

SDLT 220 and SDLT 320 Design & Integration Guide CHAPTER 6: SCSI and Controller Interface Specification 6.6 Power On Self Test When power is applied to the tape system, the system performs a Power On Self Test (POST). POST completes in approximately ten seconds. While POST is running, the tape system responds BUSY to SCSI commands. The tape system also responds to various SCSI messages during POST.

SDLT 220 and SDLT 320 Design & Integration Guide CHAPTER 6: SCSI and Controller Interface Specification 6.8 SCSI and Power Connectors This section describes how to use the connectors that are provided on the back of the SDLT tape drive. The arrangement of these connectors is shown in Figure 6-2 on page 6-5. 6.8.1 Power The pin orientation for the 4-pin power connector (TERMPWR) located on the back of the internal tape drive is shown in Figure 6-2 on page 6-5.
CHAPTER 6: SCSI and Controller Interface Specification 5. SDLT 220 and SDLT 320 Design & Integration Guide Attach the power cables to the drive. Check the SCSI cable and termination connections and ensure that they are attached correctly and seated firmly. 6.9 Loader/Library Controller Interface The loader connector (for library tape drive interface) is an RS-422 serial port set to 9600 baud, 8 bits per character, no parity, and 2 stop bits.

CHAPTER 6: SCSI and Controller Interface Specification SDLT 220 and SDLT 320 Design & Integration Guide 6.10 Configuring the Drive Configure the internal drive for TERMPWR or Wide/Narrow SCSI. 6.10.1 TERMPWR A SCSI bus must be terminated at each end of the bus. All signals not defined as RESERVED, GROUND, or TERMPWR shall be terminated exactly once at each end of the bus. At least one device must supply terminator power (TERMPWR).
C HAPTER 7 Updating the Firmware 7.1 Updating the Code When you need to update the firmware in a drive, you can do it either of two ways: • Build a firmware image tape; this tape can be used in either a manual firmware update or in a Library setting. • Update the firmware over the SCSI bus. Both of these approaches are described briefly in the following subsections. NOTE: For more information about other diagnostics tools provided by Quantum, refer to Section 1.
CHAPTER 7: Updating the Firmware SDLT 220 and SDLT 320 Design & Integration Guide 7.1.2 Making a FUP/CUP Tape SDLT Update is a tool that allows you to update a drive’s firmware (using the SCSI bus), or to create a code update (CUP/FUP) tape for an SDLT drive. SDLT Update is available on Quantum’s web site, http://www.quantum.com. Follow the path Support =>Drivers and Software and download the SDLT Update package.
SDLT 220 and SDLT 320 Design & Integration Guide CHAPTER 7: Updating the Firmware NOTE: The Firmware Upgrade will fail the microcode update process if the firmware personalities do not match; this will be noted in the history log, along with the reason for the failure. 7. Wait several minutes for the update process to complete. The Amber and Green LEDs will blink the entire time that memory is being updated. 8. When the update is complete, the drive resets itself and goes through POST.
CHAPTER 7: Updating the Firmware SDLT 220 and SDLT 320 Design & Integration Guide 7.2 Code Update Using the Library Tape Drive Interface The library tape drive interface (for SDLT) enables updating the policy/servo firmware with a new version—that is to say, image—via tape update. Follow these steps: 1. Make certain the drive contains no cartridge. 2. Send the CODE UPDATE REQUEST command. 3.
SDLT 220 and SDLT 320 Design & Integration Guide CHAPTER 7: Updating the Firmware 7.2.1 Firmware (Code) Update Troubleshooting This section lists common behaviors that you may notice as you update the tape drive’s firmware. For example: • Updating the same revision If a code update is requested and the code revision being updated is the same as the code revision already in the unit, the system updates controller code but not servo-specific code.

C HAPTER 8 Insertion and Extraction Guidelines 8.1 Applicable Library Commands This section discusses the commands and status bits that customers using a tape library interface need to be familiar with to communicate with the tape drive. The tape library system uses commands to get information from the tape drive or to initiate tape drive action.
CHAPTER 8: Insertion and Extraction Guidelines SDLT 220 and SDLT 320 Design & Integration Guide 8.1.1 General Status Packet Figure 8-1 shows what is contained in a General Status packet. Refer to this figure during the discussion of loading and unloading commands.
SDLT 220 and SDLT 320 Design & Integration Guide CHAPTER 8: Insertion and Extraction Guidelines 8.1.2 Loading a Tape These commands pertain to loading the data cartridge: • ATTENTION • LOAD • DISABLE AUTO TAPE THREAD • ENABLE AUTO TAPE THREAD. For detailed information about these commands, and for more information about the General Status Packet shown in Figure 8-1 on page 8-2, refer to the Super DLTtape™ Interactive Library Interface Specification (6464162-01) document.
CHAPTER 8: Insertion and Extraction Guidelines SDLT 220 and SDLT 320 Design & Integration Guide 8.1.3 Unloading a Tape These commands pertain to unloading the data cartridge: • ATTENTION • EJECT • UNLOAD • UNLOAD and EJECT • DISABLE EJECT ON SCSI UNLOAD • ENABLE EJECT ON SCSI UNLOAD • DISABLE AUTO TAPE THREAD • ENABLE AUTO TAPE THREAD.
SDLT 220 and SDLT 320 Design & Integration Guide CHAPTER 8: Insertion and Extraction Guidelines 8.2 Loading a Tape Cartridge (Standard Configuration) Complete this subsection to load a tape cartridge into the front of the tape drive. Because this subsection of the manual refers to some of the front panel LEDs and controls, it describes the process for manually loading a tape cartridge. 1. Insert the cartridge. Push the cartridge fully into the tape drive. 2.
CHAPTER 8: Insertion and Extraction Guidelines SDLT 220 and SDLT 320 Design & Integration Guide Hold Time for Loading (Dwell Time) When loading the cartridge into the drive, the maximum time that the picker should hold the cartridge is 250 ms (0.25 second). If a longer hold time is used, buckling and possible reel driver engagement problems could occur. Debounce Time The time allowed for the tape to stop moving (delay after insertion) is 50 ms.
SDLT 220 and SDLT 320 Design & Integration Guide CHAPTER 8: Insertion and Extraction Guidelines 1. Press the Eject button. The drive completes any active writing of data to the tape. The Drive Status LED blinks as the tape rewinds. 2. When the tape is finished rewinding, the drive ejects the cartridge and the Drive Status LED lights steadily. Do not rush removal of the tape cartridge. Wait until the drive ejects the cartridge and the Drive Status LED lights steadily before removing the cartridge. 3.
CHAPTER 8: Insertion and Extraction Guidelines SDLT 220 and SDLT 320 Design & Integration Guide 8.3.1 Unload Forces, Placement, and Timing Figure 8-2. Tolerances for Cartridge Insertion and Extraction (Standard Configuration) Eject Distance When ejecting a cartridge from the drive, the distance the cartridge can be expected to move is important; this distance is shown in Figure 8-2. Cartridge Extraction Force Limit the extraction force (applied by the picker) to 4.5 lbs (maximum).
