[. . . ] Failure to observe this precaution could result in injury or damage to property. WARNING CAUTION s The following symbols have the indicated meanings. Item requiring special attention. Actions to be avoided. Actions that must be performed. 2 Safety Precautions ­ Always Observe WARNINGS s Never attempt to disassemble or modify the drive. (for example, by removing the covers) Fire or electric shock could result. s Never place liquids on or near the drive, or allow metallic items or other foreign objects inside. [. . . ] · Data compression control setting 2 (DC Control 2) is set by switch 8 (factory default is OFF). ON Switches 1 to 4: Switch 5: Switch 6: Switch 7: Switch 8: Reserved Terminator Power Reserved DC Control 1 DC Control 2 12345678 Note Normally, the factory default settings should not be changed. 10 Hardware Information Terminator Power Setting ON 12345678 This setting (DIP switch 5) enables or disables terminator power to the SCSI bus. Terminator power is enabled when this switch is set to ON (factory default). Data Compression Control Setting (DC Control 1) ON 12345678 This setting (DIP switch 7) enables or disables control of the data compression function in the drive. The internal compression control function is enabled when this switch is set to ON (factory default). Data Compression Control Setting (DC Control 2) ON 12345678 This setting (DIP switch 8) enables or disables control of the compression function by the backup application program. The backup program controls the compression function when this switch is set to OFF (factory default). Hardware Information 11 s Rear Panel 1 2 3 SCSI ID (Pins 0 to 3, from right to left) No connection (not used) Parity Enable (PE) Note Place any unused jumper straps over the pin at one side, or retain in a safe place. In the following description, "jumpered" means that a jumper strap is installed over two pins, and "not jumpered" means that a strap is installed over only one pin, or not at all. 1 Interface Connector This is the SCSI signal connector for controlling the STD-11000 BuiltIn DAT. 2 DC Connector (+5/+12 V) This connector supplies power to the STD-11000 Built-In DAT by connecting a power cable in the server. 12 Hardware Information 3 Option Jumpers The following settings are made by jumpers on the header on the rear panel. · SCSI ID (factory default setting is ID4) · Parity function (factory default setting is enabled) SCSI ID Setting This setting determines the SCSI ID for this device. Header pin pairs 0 to 4 are used for this setting. Pin pair 3 (factory default setting: not jumpered) Pin pair 2 (factory default setting: jumpered) Pin pair 1 (factory default setting: not jumpered) Pin pair 0 (factory default setting: not jumpered) Note Confirm that the SCSI ID setting is different from all other connected SCSI devices. SCSI ID 0 1 2 3 4*1 5 6 7*2 8 9 10 11 12 13 14 15 Pin pair 3 × × × × × × × × Pin pair 2 × × × × × × × × Pin pair 1 × × × × × × × × Pin pair 0 × × × × × × × × = jumpered × = not jumpered *1 Factory default setting *2 Do not set to SCSI ID 7 Hardware Information 13 Parity Setting This setting enables and disables the parity function for this device. The leftmost pin pair on the jumper header determines the setting: the parity function is enabled when the jumper is present (factory default). PE (factory default setting: jumpered) Note Normally, this setting should not be changed from the factory default. 14 Hardware Information Installing in the Server When connecting or disconnecting peripheral devices or the server, always unplug the AC power cord from the AC outlet. Connecting or disconnecting devices while the power cord is plugged in could cause an electric shock. However forcing ejection can damage the tape, so this should not be done except in an emergency, and only after first turning the power off and on to reboot. 18 Hardware Information Cleaning s Cleaning the Head Cleaning is important to remove dirt buildup from the magnetic head that accumulates from the operating environment and by normal tape usage. When the head is dirty, reading and writing performance can be degraded, and the life of the data cartridge can be shortened or the tape ruined by scratching. 1 Load the supplied cleaning cartridge or the EF-3237C/EF-3237CN into the drive. Cleaning starts automatically, and the cleaning cartridge is ejected after about 30 seconds. 2 Remove the cleaning cartridge and resume normal operation. Note · The EF-3237C Cleaning Cartridge can be used about 30 times, and the supplied cartridge and EF-3237CN can be used about 50 times. If the STATUS LED is blinking when finished cleaning, the cleaning cartridge has reached the end of its useful life. (Refer to 4 STATUS Indicator under the Part Names on page 9 for a description of this indicator. · If a cleaning cartridge is loaded which is no longer usable, it will not eject automatically: press the EJECT button to remove it. · Avoid touching the tape side of the cleaning cartridge with your fingers, and do not rewind the cleaning tape in an attempt to reuse it. Tape side of cleaning tape Hardware Information 19 s Head Cleaning Frequency Clean the head according to the amount of drive use, as shown below. Setting the tab as shown at the right prevents data already written on a tape from being erased. Setting the tab as shown at the left enables writing on the tape. Write enabled Write disabled 22 4 mm Data Cartridges Handling Precautions s Usage Precautions Before Using a Tape · Do not use a data cartridge if appears to be damaged or warped. · If a data cartridge has been stored in an environment outside of the operating conditions, allow the tape to stand in the operating environment for a longer period than that at which it was outside of the conditions (up to 8 hours) before use. If the storage temperature is much different from that of the operating location, the cartridge should be allowed to acclimatize gradually, allowing about one hour per 10ºC temperature difference, rather than changing the temperature suddenly. When Loading in the Drive Load the data cartridge according to the Loading a Cartridge paragraph. [. . . ] Also, when writing the backup copies, we recommend confirming the copy by using the verify function of the backup software. Please refer to the documentation for the backup software regarding use of the verify function. By taking these steps, even if read errors are encountered as a result of dirt or dust on the tape, the other tape can be used for data recovery, preventing loss of critical data and programs. Three-Generation Data Management We recommend using a three-generation data management system for backing up data saved on disk. This system uses three tapes (call them A, B and C), with the disk data saved in the order A-B-C as follows: disk data is saved to tape A on the first day, tape B on the second day, and tape C on the third day.
