Page 14: Rear Panel Features
Setting up the RWZ52 Rear panel features Identify the following rear panel features before you connect the RWZ52 to the host system. Figure 2-1: Rear Panel Features The following numbers correspond to the numbers in the drawing on the previous page. -
Page 15: To Set The Scsi Id
Step 3:Set the SCSI ID by pushing in on the button directly above or below the address window with a small screwdriver or the point of a pen. (A small screwdriver was shipped with the RWZ52.) The button above the window decreases the number by one; the button below the window increases the number by one. -
Page 16: To Set The Operation Mode
To set the operation mode The mode selection switch designates in which mode the RWZ52 operates. Select 0 to operate the RWZ52 as a Digital recognized device. This is the default mode. Select 1 to operate the RWZ52 as a Hewlett Packard (Model 1300T) recognized device. -

Page 19: Using Optical Disks
Using Optical Disks The optical disks that you use in the RWZ52 are an integral part of the storage process. This chapter provides information on the following topics: • choosing an optical disk • labeling an optical disk • maintaining an optical disk •... -
Page 20: Choosing An Optical Disk
Choosing an optical disk Optical disks are available in two capacities, 650 Mbytes and 1.3 Gbytes. The RWZ52 can read from and write to both 650-Mbyte disks and 1.3- Gbyte disks. However, RWZ52 users should choose 1.3 Gbyte optical disks to receive maximum storage capacity. -
Page 21: Labeling An Optical Disk Cartridge
Using Optical Disks Labeling an optical disk cartridge Make it a practice to label your optical disk cartridges. You are provided adhesive labels with each disk for this purpose. Here are some suggestions for labeling: • date of format or initialization •... -
Page 22: Write-Protecting An Optical Disk
Using Optical Disks Write-protecting an optical disk Each side of an optical disk can be write-protected by sliding the write- protect button in the direction of the arrow on the cartridge. With rewritable optical disks, the use of the write protect button ensures data safety for files that have been previously written to the disk and prevents any additional files being written to the disk. -
Page 23: Maintaining An Optical Disk In Good Condition
Using Optical Disks Maintaining an optical disk in good condition Follow these guidelines to maintain your disk in good condition: • Do not expose the disk to extreme magnetic fields. • Do not expose the disk to dust particles. • Do not expose the disk to extreme temperatures or extreme humidity. -

Operating the RWZ52 Identifying front panel features The following numbers correspond to the numbers in Figure 4-1 on page 4-1. Cartridge slot Opening for inserting optical cartridge. Activity indicator Remains lit while a cartridge is loaded or unloaded, during the powerup selftest sequence, and any time the drive is being accessed. -
Page 27: To Manually Eject A Cartridge
To manually eject a cartridge The RWZ52 does not automatically eject an optical cartridge if a power failure occurs. An eject tool was shipped with the RWZ52 to eject a cartridge manually. Follow these steps to remove the cartridge from the optical drive: Step 1.Disconnect all power to the drive. -
Page 29: Software Applications For The Rwz52
Software Applications For The RWZ52 The RWZ52 is supported on many hardware platforms and by several software applications. The two most common applications are DEC Optical Storage Desktop Software(OSDS) for OpenVMS VAX and AXP on workstations and the CorelSCSI packages for PC platforms. - Page 30 Network Manager WORM functionality for the RWZ52 standalone drive connected to workstations is only supported on a non-clustered, VAX platform with OSDS OpenVMS VAX software. In the future additional platforms and clustered environments may be supported using the OSDS software.
