Configuring the Drive Sled for Single-Ended Operation The 8505XL drive sled assembly houses a SCSI channel adapter boar d. Y ou must ensure that the drive sled assembly is set to single-ended operation. Caution: Use prope[...]

8 Chapter 1: Installation Figure 1-3 Setting the Drive Sled for Single-Ended Operation Note: Y our system disk should always be set to SCSI ID 1. Be sur e each SCSI device on a bus has a unique SCSI addr ess (ID). The SCSI bus cannot function properly if mor e than one device has the same SCSI ID. T erminating the SCSI Bus The internal SCSI channel[...]

12 Chapter 1: Installation T urning On Power to the T ape Drive When power is applied to the 8505XL, watch for the following: • All three of the tape drive ’ s LEDs light. • The tape drive ’ s 30-second power -on self-test begins. • When the self-test is complete, the top and bottom LEDs turn of f; the middle LED is off or fl ashes irr e[...]

Installing the Tape Drive 13 1. Locate a data cartridge that does not contain any valuable information and make sure that its write-pr otect switch is set to write-enable (see Figure 1-6). 2. Gently push the data cartridge as shown (in Figur e 1-7) until the load mechanism pulls the cartridge into the drive. Figure 1-6 W rite-Enable/Disable Switch [...]

14 Chapter 1: Installation Figure 1-7 Loading a Data Cartridge 3. W ait while the tape drive loads the tape, determines the tape format, and positions the tape to the logical beginning of the tape (LBOT). This takes about 45 seconds. When the gr een LED is on solid, the tape drive is ready .[...]

Installing the Tape Drive 15 4. Perform a backup operation to write a small amount of data to the tape (see your IRIX administration documentation, as r equired). 5. Rewind the tape and read the data written in step 4 and compar e it to the original. This determines whether the softwar e and tape drive are functioning properly . If problems occur ,[...]
