Setting the SCSI ID with the DIP Switches To set the SCSI ID using the DIP switches, follow these steps: 1. Locate the SCSI ID DIP switches on the back of th e tape drive, as shown in Figure 1. 2. Change the DIP switch settings to the correct SCSI I Df o ry o u rc o n f i g u r a t i o n .
Setting the SCSI ID with Jumpers To set the SCSI ID using jumpers, follow these steps: 1. Locate the SCSI ID jumper block on the back of the tape drive, as shown in Figure 1. 2. Install the jumpers on the jumper block to obtain the correct SCSI ID for your configuration.
Setting the SCSI ID with a Remote Switch If you want to set the SCSI ID remotely, you can attach a remote switch assembly (not provide d with the tape drive) to the tape drive’s SCSI ID jumper block. To set the SCSI ID with a remote switch, follow these steps: 1.
Terminating a Single-Ended Tape Drive The sing le-ended tape dri ve includes two sing le in-line package resistor terminat ors (R-packs) that can be lef t in place if the tape drive ter minates the SCSI bus. CAUTION The R-packs must be removed if the tape drive does not terminate the SCSI bus or if you plan to use an external SCSI bus termination.
2. Using a pair of flat-nose wiring p liers, grasp each R-pack at the center and pull it straight out . Be carefu l not to sque eze the plie rs too tigh tly or you may break the R-pack.
Installing the Tape Drive in a PC Drive Bay If you are plannin g to mount the tape drive in a full -high PC drive bay, follow the guidel ines in this sec tion. Otherwise, refer t o Appendix A for installation requirements, the n resume reading on page 20, “Performi ng the Initial Po wer On.
5. If necessary, remove o ne of the floppy disk drives to provide an empty full-high drive bay for the tape drive. CAUTION If you remove floppy disk dri ve B to install the tape drive, be sure to change your system configuration to reflect this. Re fer to your computer owner’s manual for de tails on running the syst em’s setup program.
3. From the front of the c omputer , thread the SCSI cable into the computer through the open bay. Slide the tape drive into the bay until the faceplate is f l u s hw i t ht h ef r o n to ft h eb a y . 4. Secure the tape drive to the drive bay as instructed in your computer owner’s manual.
7. Connect power ca ble from the power supply to the 4-pin power connector on the back of the tape drive. CAUTION ■ Make sure that the PC power is off bef ore you connect the c able. ■ Do not force the pl ug into the connecto r. The keyed edges of the plug and the co nnector must m atch.
When power is applied, the tape drive performs its power-o n initia lizatio n and self-t est (P OST). Assumi ng that no data cartridge is loaded and that the t ape drive is connected correctly, POST takes about 65 seconds, as follow s: ■ During the first part of POST, bot h the amber and green LEDs are lit.
4. Push the doo r shut and wai t while t he tape dr ive loads the tape and positions it at LBOT. W hen the amber LED is off and the green LED is on, the t ape is loaded and the tape drive is ready. 5. Write approximately 500 MBytes of data to the tape.
2 Operating the Tape Drive This section in cludes information about the following: ■ Reading the tape drive’s LEDs ■ Setting the write-prot ect switch on the data cartridge ■ Loading and unloading a data cartridg e Figure 9 s hows the con trols and i ndicators o n the front panel of the EXB-8500c.
Table 2 shows specifi c combinations of LEDs that m ay occur during tape drive operatio n. You may occasionally observe LED combinations an d sequences not described in Table 2. These other combinations represent special or unusual condition s that are beyond the scope of this table.
Selecting Data Cartridges By selecting high-qu ality data cartridges and storing them properly, you can expect a long shelf -life and optimal data integrity fro m them. High quality tapes also help maintain tape drive reliability by minimizing wear on the recording heads.
Setting the Write-Protect Switch EXATAPE™ 8mm data cartridges are equipped with a write-prote ct switch, shown in Figure 10, to prevent data on the tape from being uninte ntionally over writte n. Before loading a data cartridge in the tape drive, ens ure that the write-prote ct switch is set correctly for the desired operation.
Loading a Data Cartridge To load a data cartridge into the tape d rive, follow th ese steps: 1. Ensur e that the wri te-protect s witch has been s et correctly for the de sired operatio n, as explained on page 26 .
wait a few seconds and press the button again to ej ect the tape. To unload a data cartridge , press the unload but ton on the tape drive’s front panel. The tape drive comple tes the current operation, write s any buffered data to t ape, unloads the tape fr om the tape p ath, and ejects the cartridge.
3 Preventive Maintenance The only routine maintenance require d by the tape drive is regular cleani ng of the tape drive heads and tape path. Use only an Exabyte or Exabyte-approved 8mm Cleaning Cartridge. Proper stor age and maintenance o f your data cartridges will maximize the shelf life of your tapes and assure data integrity.
Using the 8mm Cleaning Cartridge CAUTION To prevent contamination of the tape drive and damage to the heads, do not use the c leaning cartridge for more than the number of cleaning cycles specified on t he cartridge label .
3. Insert the cleanin g cartridge in the tape drive and close the do or. 4. The cleaning cycle is perfor med automatically by the tape drive and takes approximat ely 38 seconds. When the cleani ng cycle is complete, the cl eaning cartridge is automat ically unloaded and ej ected from the tape drive.
■ Keep the storag e location as free o f airborne particulates as possible. To eliminate obvious s ou r ce s of particulates, do not permit anyone to s mo ke , e a t , o r d r in k near the storage area , and do not store cartridges near a copie r or printer that may emit toner and paper dust.
Replacing Data Cartridges Approximately once each year, you may want to run each tape through a full pass and check its err or statistics. If errors have increased significantly since the previous test or if they exceed a certain predet ermined threshold, you should re-archive th e data to a new tape and discard the old tape.
