1 Preparing for installation  
Installing or replacing a tape drive in the 430 or 215 library involves the  
following steps:  
! Removing an existing tape drive or drive service access cover  
! Installing the new tape drive  
! Testing the library and resuming operation  
Note: The illustrations inthese instructions show the430 SCSI library. The  
component locations aresimilarin the215library. Where necessary,  
the 430M-FC is also shown.  
To prepare for installation:  
1. Obtain a #2 Phillips screwdriver.  
2. Ensure that the environment is free of conditions that could cause  
electrostatic discharge (ESD). If possible, use an antistatic mat and  
grounded static protection wristband during installation. If a mat and  
wristband are not available, touch a known grounded surface, such as  
the computer’s metal chassis.  
CAUTION  
If the library is attached to a SCSI bus, make sure the  
library is not communicating across the bus before  
powering it off. Powering off the library may disrupt  
communication on the SCSI bus.  
3. Power off the library and disconnect the power cord.  
WARNING!  
Beforecontinuingwiththeseprocedures, besurethat  
the library’s power switch is in the off position and  
that the power cord is disconnected from the library.

2 Removing the tape drive  
If you are replacing an existing tape drive, follow the steps below to remove  
the drive. If you are installing an additional tape drive, skip to Section 3,  
1. From the library’s back panel, disconnect the cables from the back of the  
tape drive you plan to replace. If you are replacing a SCSI tape drive,  
remove any terminator that might be installed on the drive.

2. Use a #2 Phillips screwdriver to release the two captive screws that  
secure the tape drive carrier to the library.

3 Removing the drive’s service access cover  
3. Remove the drive carrier by grasping the handle and pulling it straight  
out of the library. The drive carrier weighs about 5 pounds; make sure  
you support the bottom of the carrier as you remove it.  
3 Removing the drive’s service access cover  
Follow these steps if you are installing a tape drive in an empty slot.  
1. From the back panel, use a #2 Phillips screwdriver to release the two  
captive screws that secure the service access cover to the library.

2. When the screws are loosened, remove the drive access cover.

4 Installing the tape drive  
4 Installing the tape drive  
CAUTION  
Do not install a mixture of Fibre Channel and SCSI tape  
drives in the library. Mixing drive interfaces could  
cause data loss.  
1. Insert the tape drive so that the handle is at the top and the fan is at the  
bottom, as shown in the following figure. The drive should slide easily  
toward the front of the library.  
2. Tighten the captive screws on each end of the drive carrier to  
8.0 inch-pounds (9.2 kg-cm) of torque.

5 Connecting the cables (SCSI library)  
5 Connecting the cables (SCSI library)  
For the 430M, 430A, 215M, and 215A SCSI libraries, connect the SCSI cables  
as described in this section. For the 430M-FC Fibre Channel library, go to  
CAUTION  
To avoid damaging the tape drive, make sure the  
library is powered off when you connect it to the SCSI  
bus.  
1. If you replaced a tape drive, reconnect the SCSI cables (or cable and  
terminator) to the new tape drive as they were before. If you installed  
an additional tape drive that will be on the same SCSI bus as the other  
drives in the library, remove the terminator from the adjacent drive and  
install it on the new drive. Then, use the SCSI cable provided in the kit  
to connect the new tape drive to the adjacent drive. The following  
figure is an example of a typical cable and terminator configuration for  
three tape drives on a single SCSI bus.  
Library  
SCSI connectors  
Jumper cables  
Terminator  
SCSI cable  
(to host)  
Tape drive  
SCSI connectors  
2. Reconnect the power cord and power on the library. The library  
automatically calibrates the position of the new tape drive.  
3. If you installed a new tape drive, set the SCSI ID for the drive as  
described in Exabyte 430M and 430A Libraries Installation and Operation or  
Exabyte 215M and 215A Libraries Installation and Operation. If you  
replaced a drive, the new drive automatically assumes the SCSI ID of  
the old tape drive.

6 Connecting the cables (Fibre Channel library)  
6 Connecting the cables (Fibre Channel library)  
For the Fibre Channel 430M-FC, connect the optical fiber cable as follows:  
1. Remove the protective plug from the optical fiber connector on the new  
tape drive, if present.  
2. Attach an optical cable from the Fibre Channel hub or switch to the Fibre  
Channel connector on the new tape drive, as shown in the following  
figure.  
Note: You can use the optical cable provided in the kit, or you can use  
your own cable. Make sure that the cable is compatible with  
the GBIC on the tape drive and on the hub or switch.

3. Reconnect the power cord to the library, then power on the library. The  
library automatically calibrates the position of the new tape drive.

7 Testing the library and resuming operation  
7 Testing the library and resuming operation  
Before resuming operation, use the Demo Menu from the operator panel to  
ensure that the robot and the newly installed tape drive are  
communicating correctly. The Demo Menu causes the robot to randomly  
move cartridges from slot to slot, including the fixed cartridge slots.  
To test the library operation using the Demo Menu, follow these steps:  
1. Insert a cartridge in the entry/exit port.  
Note: All other cartridges in the library can remain where they are.  
The testing can also be performed without any cartridges other  
than the one in the entry/exit port.  
2. If necessary, disable security as follows:  
a. Press the [MENU] key to display the menus. Press the down arrow key  
until “Security” appears on the screen, as shown below. If security  
is enabled, “LCD Password” appears on this screen.

c. Use the left and right arrow keys to move across the columns. Enter  
your password using the up and down arrow keys to select a  
number. Press [ENTER]. Security is then disabled.  
3. Change the control mode to LCD as follows:  
a. Press [MENU] to display the menus, then press the down arrow key  
until “Robot Mode” appears. The Robot Mode screen shows the  
currently activated mode.
