SETTING THE SCSI ID

NOTE: It is important that each disk

module be given an ID (from 0 through 6) that is not used by any other Z Microsystems disk module on the same bus, or any other device, such as a tape drive or CD-ROM that may already be on the bus.

NOTE: Depending on the computer

of the host computer, the choice of ID number for the TranzPak 6 disk module may be limited. Some operating systems reserve certain ID numbers for disk drives. Consult the computers User Guide if the initial ID setting is not recognized by the host operating system.

handle is fully in.

When there is power going to the disk module, the SCSI Identification (ID) number appears in a window above the function switch on the disk module front panel.

At the top of that window is a small hole in the panel. To set or change the SCSI ID, use a small blunt-end probe and gently but firmly press the switch that is behind the panel. Each push (click) advances the ID by one number.

NOTE: The host computer may or

may not recognize the addition of a device on the SCSI bus. The computer may have to be rebooted after adding a new device. Refer to the operating system manual.

FUNCTION SWITCH ELECTRICAL DESCRIPTION

The function switch has four positions:

NOTE: Some disk manufacturers

require that the power to the disk be cycled after setting it to a write-protect mode in order to use the write-protect feature. The only way to determine if the disk requires power-down to change to Read-Only is to turn the function switch to a RO position, then try to write to the disk.

FUNCTION SWITCH VERSIONS

 Two Read/Write (RW). The hard

disk can be fully accessed by the host computer. There is no front panel LED to indicate this position.

 Two Read-Only (RO). The orange

Read-Only LED will be lit.

The function switch has two modes:

 Handle locked

 Handle unlocked

The function switch also has two versions:

 Knob

 Key lock

The switch functions identically in both versions. The only difference is that with the key lock version, a key is required to be inserted into a lock in order to change the position of the switch.

LOCKING THE DISK MODULE AND HARD DISK

On the disk module front panel on each side of the word SECURITY there are small padlock icons.

The left icon indicates an unlockedhandle mode when the function switch is in one of its two left positions (either

RW or RO). The right icon indicates a locked-handle mode when the function switch is in one of its two right positions (either RW or RO).

Page 21

Operation

LOCKING THE DISK MODULE AND HARD DISK

When the function switch knob is in either the left two disk accessing positions, the disk module handle can be moved freely from being Fully In to power the hard disk, to being Fully Out to remove power from the hard disk drive and to remove the module from the docking base.

When the function switch knob is in either of the right two positions, the disk module handle is locked and cannot be moved. The disk module is locked in the docking base, and the hard disk is locked in either a powered or unpowered state (depending on the position of the module handle).

In either a Read/Write or Read- Only disk accessing state (depending on the position of the function switch).

WARNING: Be sure to return the

function switch to the unlocked mode before attempting to remove the disk module.

The main reasons for using a locked position are to prevent unauthorized reading and/or writing to the hard disk, and unauthorized removal of the disk module.

Depending on the module handle position, the hard disk drive can be locked with or without power.

Both the knob and key lock version of the function switch operate in the same way. The only difference is that with the key lock version, a key is needed to change all positions of the function switch. When the key is removed, the function switch position cannot be changed.

POWERING DOWN THE HARD DISK

WARNING: Do not attempt to pull

the handle further out while the red wait LED flashes. Movement of the disk module could cause physical damage to the hard disk.

Once the hard disk is operational and set to the desired mode, it is ready to be used on the SCSI bus.

Before the disk can be powered down, the disk module handle must be moved from the Fully In position to the In position.

The Power/Wait LED changes color from green to red and begins to flash indicating wait. There is also a single short tone, which is an audible acknowledgment that power was removed from the hard disk drive.

The flashing red light will remain for about 15 seconds, which is the timedown or spin-down period. The light then will go out

REMOVING THE DISK MODULE

When the red Power/Wait LED extinguishes, the green center Active/Remove LED will start to blink, indicating that the disk module can be safely removed from the docking base. Pull the handle Fully Out.

The handle is designed to require a firm pull in order to prevent accidental removal of the disk module. The
