Figure 15 Front panel Front panel 1 2 3 4 5 6 7 Cartridge slot Power LED (external drives only) Ready LED Fault LED Clean LED Media LED Eject button HP StorageWorks DLT VS160 Tape Drives User Guide 35 Front panel LEDs There are four LEDs as illustrated in the diagram. (See Figure 15. ) Ready - far left, green · On, green: power is on and the drive is ready for use · On, blinking: the drive is busy · Off: no power to the tape drive NOTE: On external drives, the Power LED also indicates that power is on. Fault - left, amber · On: internal firmware error · Slow blink (1 per second): user-initiated write/read diagnostic failed · Fast blink (3 per second): servo or mechanism error Clean - right, amber · On: cleaning is required · Medium blink (2 per second): cleaning in progress · Slow blink (1 per second): calibration error or permanent write/read error Media - far right, green · On: DLT1 (VS80) format DLTtape IV cartridge loaded (you can read, but not write to, this cartridge) · Slow blink: unsupported format or damaged cartridge Eject button Use the Eject button to eject the tape cartridge from the drive. When you press the button, the drive completes any active writing of data to the tape, then ejects the cartridge. You can also use the eject button to perform an emergency reset or to put the drive into code update mode, see "Unload/Eject Button Functions" on page 41. 36 Operating your tape drive Loading and unloading Inserting cartridges Figure 16 Inserting a cartridge 1 2 Label area Arrow indicates leading direction 1. Insert the DLTtape VS1 cartridge into the slot in front of the drive with the markings uppermost and facing the drive door. 2. Apply gentle pressure until the drive takes the cartridge and loads it. The Ready LED flashes green while the drive performs its load sequence. When the cartridge is ready for use, the Ready LED shows steady green. (If the Media LED is also on, you have used a DLTtape 1V (VS80) cartridge. See "Use the correct media" on page 43. ) HP StorageWorks DLT VS160 Tape Drives User Guide 37 Removing cartridges CAUTION: Never try to remove a cartridge before it is fully ejected or power off the tape drive while a cartridge is still loaded. Failure to remove a data cartridge may result in cartridge or tape drive damage. Press the Eject button on the front panel. When you press the button, the drive completes any active writing of data to the tape, then ejects the cartridge. NOTE: You can also use the eject button to perform an emergency reset or to put the drive into code update mode, see "Unload/Eject Button Functions" on page 41. Figure 17 Ejecting a cartridge 1 Eject button 2. The drive will complete its current task, rewind the tape to the beginning, and eject the cartridge. The Ready LED will flash to indicate that the unload is still in progress and will show steady green, when the cartridge is ready for removal. Removing power from the drive To ensure reliable operation, do not remove power from the drive during read, write, fast-search, load and unload activities. 38 Operating your tape drive Understanding LEDs At power on The tape drive performs a power-on self-test whenever power is applied. The test takes between 25 seconds (no cartridge loaded) and several minutes (cartridge loaded). · The LEDs illuminate one at a time, from left to right, starting with the Ready LED, next the Fault LED, and finally the Clean LED, at approximately one second intervals. · The Media LED illuminates very briefly and then all the LEDS go off. The Ready LED then blinks for 10 to 15 seconds. [. . . ] Always use the supplied multimode terminator for proper operation. 58 SCSI configuration guide Figure 20 SCSI termination on a single tape drive If you have more than one device on the SCSI bus, daisy chain them by connecting a cable from the SCSI-OUT connector on the first device to the SCSI-IN connector on the second device and make sure that the second device is terminated. (Always use an LVD-rated cable and an LVD-rated or multimode terminator. ) Figure 21 SCSI termination in daisy-chained external drives HP StorageWorks DLT VS160 Tape Drives User Guide 59 SCSI cables Cables matter in SCSI systems. There are two factors to consider: cable length and cable quality. Cable length · For LVD SCSI the maximum length for a single device is 25 meters. For multiple devices, the maximum combined internal/external length is 12 meters. [. . . ]
