Congratulations on purchasing what we think is the finest removable
cartridgesystem onthe market.Bering OptiPacdrives arebuilt foryears
of reliable service. We're sure you'll agree as you begin to work with
your drive.
Features The Bering OptiPac 2652MD subsystem is a 5.2GB Magneto-Optical
removable cartridge disk drive with a 1.3GB fixed disk compatible with
Hewlett-Packard 1000E, M, or F computers running RTE-IVB and RTE-
VI. In this manual we refer to the Bering OptiPac disk drive as OptiPac
and all HP systems as computer, unless otherwise indicated.
Note: The Bering OptiPac 2652MD magneto-optical cartridge drive supports
1.3GB and 2.6GB cartridges. However, 1.3GB cartridges are read-only.
These cartridges are available through Bering Technology’s sales
department.
Serving a wide range of storage needs, the OptiPac comes in the
following configuration with HP7906M emulation. This provides a plug
and play solution to the aging inventory of HP7906M disk drives.
•2652MD – a 5.2GB Magneto-Optical cartridge drive with a 1.3GB fixed
disk
The OptiPac 2652MD subsystem uses a 5.25-inch removable cartridge
which can store 2.6GB (1.3GB/side). This means:
•Each cartridge contains multiple rings, so physical removal is not
required to change to another ring. Each ring emulates a 10MB HP
7906M cartridge.
•Your storage capacity is limited only by the number of cartridges you
use.
•Your data is portable and secure. Just remove the cartridge from the
drive and take it with you, or store it in a safe place.
•Your data cartridge is protected in a durable lexan case.
•Your OptiPac can be used to back up the data on fixed disks.
The OptiPac provides fast, reliable storage that's always on hand. No
software or hardware modifications are required. The OptiPac supports
the AMIGO HP disk command sets.
The fixed disk and each cartridge is split into multiple 10.1 MB Rings,
which emulate a 10MB cartridge in the HP 7906M. The fixed disk has
128 (H0–H127) rings and each removable 2.6GB cartridge has rings to
128 (0–127), depending on the cartridge capacity and sector size.

Selecting a ring from the front panel of the OptiPac is equivalent to
changing the cartridge in the 7906M. The first ring on the fixed disk
(H00) emulates the fixed disk in the 7906M, and is not accessible from
the front panel controls.
The rings on the fixed disk will all have an ID on the LCD display
beginning with “H.” Each ring on the removable cartridge is just a
number. So ring 23 on the hard drive will be displayed as “H23,” while
ring 23 on the cartridge will be displayed as “23.”
sDANGER: Use of the OptiPac other than as prescribed in this manual may result in
exposure to hazardous invisible laser radiation if the case is open during
operation. Avoid direct exposure to laser radiation. Do not operate the
OptiPac while the cover is removed.
Compatibility The OptiPac 2652MD drive can read from, but not write to, 1.3GB MO
cartridges. It can read and write to 2.6GB cartridges.
Note: 5.2GB cartridges are not compatible with the OptiPac and should not
be used.
The 1.3GB cartridges have a capacity of 650 MB/side and the 2.6GB
cartridges have a capacity of 1.3GB/side. The cartridge must be ejected
and flipped over to access the other side.
Regenerating the
Operating System Your HP operating system does not require regeneration if the 2000MX
MAC controller board replaces an HP 13037 MAC controller in the same
slot where the HP MAC controller was removed from.
If the 2000MX is inserted into any other slot, the operating system will
have to be regenerated.
Magneto-
Optical
Technology
All of the Bering OptiPac disk drives are based on magnetic and optical
technology. Like hard disks, a Magneto-Optical drive writes data to the
cartridge using a strong magnet that changes the magnetic fields at
specific locations from 1's to 0's and vice versa. But because of the
polycarbonate surface of the cartridge, the magnet is not powerful
enough to change the polarity of a bit by itself. This is where the optical
part of the write process comes in. In order for the magnet to change
the polarity of a bit, the area must be heated to a high temperature by
a focused, fine-point laser.
Because of the polycarbonate substrate on the cartridge, data stored on
Magneto-optical cartridges is highly secure for a long period of time.
The estimated storage life of data stored on this media is greater than
twentyyears.Also themagnetic headdoesnot “float”next tothesurface
such as fixed disks. This means it is virtually impossible for the head
to crash.

Conventions in this Manual
OptiPac 2652MD User's Manual 3
Conventions in
this Manual We'll use the following conventions to make the information in this
manual more clear and predictable:
•Keyson the keyboard are indicated by capital letters enclosed in square
brackets, e.g., [ENTER], regardless of whether the characters on your
keys are actually capitalized. On the other hand,buttons on the OptiPac
are indicated by underlined capital letters alone followed by the word
button, e.g., ENTER button.
•A fontlike this indicates text you should see on the LCD. The bold font
will otherwise follow the conventions herein.
•Italics in any type face, like this, have a limited number of possible
meanings:
Words as words, letters as letters, or numerals as numerals, e.g., “the
word enter can be confused with the key on your keyboard, therefore
we will use type in its place.”
Titles of books, booklets, or disks, e.g., Bering OptiPac 2652MD User's

Symbolic of variable words, characters, or numerals. That is, something
mustbeinthevariable'splace, buttheexactcontentsvary withdifferent
situations and cannot be specified without knowing a particular
situation. Variable is not synonymous with optional. Frequently the
letter(s) n(for numerals), orx(for words or characters) are used to hold
the place of the variable, e.g., “the program will respond that there are
nwidgets.”

3. Insert the cartridge into the drive with either the Aor Bside up, the
write-protect switch toward you and the metal shutter facing the drive.
As you do so, the drive will pull the cartridge inside and seat it in the
drive slot. The drive motor will then spin the cartridge up to speed in
about five seconds as the Activity LED on the front panel flashes amber.
Once the drive reaches the proper speed, the Activity LED will turn
green.
sCAUTION: Never move or transport the OptiPac with a cartridge in the drive,
operating or not.
New Cartridges The first time a cartridge is used it must be formatted from the
Removable Disk Utilities menu. Using an unformatted cartridge can
cause loss of data. You should indicate the date on the label when a
cartridge is formatted. Remember to format both sides of the new
cartridge.

Write-Protecting a Cartridge
12 OptiPac 2652MD User's Manual

Write-Protecting
a Cartridge You may want to write-protect one or both sides of a cartridge after
removing it from your OptiPac. Write-protection prevents accidental
erasure or overwriting data on the removable cartridge.
The write-protect switch for the side which is facing up is the plastic
slide switch in the lower left corner of the cartridge.
1. To write-protect a side of the cartridge, slide the appropriate tab toward
the left edge as shown in Figure 3-3.
When you can see through the circular hole to the right of the tab, data
cannot be written to that side of the cartridge and existing data cannot
be erased from that side by ordinary means.
2. To disable write-protection, slide the tab toward the center of the
cartridge so the hole is closed.
Figure 3-3: Cartridge write-protect switch
Note: The appearance of cartridges varies between manufacturers, but the
location of the write protect switch should always be the same.
