Chapter 1
INTRODUCTION
Description
This chapter provides general, functional, and physical descriptions of the F880ES tape drive. It
also has instructions on how to open up the drive to gain access for operation and servicing, and a
seriesofillustrationsshowingthe locations ofall
the major parts ofthe tape drive.
GENERAL DESCRIPTION
The Cipher Model F880ES is adual-density (l600 and 3200 bits per inch) magnetic tape drive
designed to provide backup for high-capacity disk drives
and data interchange between systems.
The F880ES exchanges data with other components ofaSCSI system and transfers that data to
and from half-inch tape reels of7, 8.5, and 10.5 inches.
Figure 1-1 is an illustration of an F880EStapedrive.
FUNCTIONAL DESCRIPTION
The F880ESdrive is made up of three functional components: the interface, the drive electronics,
and the drive mechanism. These three elements interact to accomplish the various functions
performedby
the drive.
The drive records on tape
data transmitted across the SCSI bus and reads recorded data from tape
and transfers it to the SCSI bus. To perform these functions amicroprocessor interprets
commands from the interface, accelerates and decelerates the tape, positions the tape at the
read/write head, detects tape position, controls formatting, and provides status outputs.
The drive writes
data to tape using the phase encode method ofrecording. Nine tracks are written
simultaneouslyacross the width of the tape, eighttracks of data and a parity track.
The tape drive is self-loading. The operator inserts areel oftape
in the opening of the front panel
and presses aload switch. The drive then automatically seats the reel on the supply hub, threads
the tape around the tension arm, across the read/write head, and around the take-up hub. The
tape is positioned
at BOT and properly tensioned.
The interface translates SCSI commands arriving on the SCSI bus into drive executable
commands, and it also translates tape drive data and status signals into the appropriate format for
the SCSI bus.
1-1

Figure 1-1. F880ES Rack-MountTape Drive
PHYSICAL DESCRIPTION
The F880ES tape drive consists of three main assemblies: the chassis, the deck plate, and the
printed circuit board.
All components
and subassemblies are mechanically fastened to a cast-aluminum deck plate,
including two direct-drive dc motors with reel hubs, apower supply, the read/write head, sensors,
the tension arm, and the front panel. The deck plate is mounted to hinges inside a metal chassis
that encloses critical parts, as well as the printed circuit board, which contains all drive control
circuitry and the SCSI interface. The drive's top cover protects the parts attached to the top of the
deck plate, as well as the tape path and the tape.
Designedfor
mounting in a standard 19-inch RETMA equipment rack or atable-top enclosure, the
drive is 8.75 inches high, 19 inches wide, and 22.7 inches deep and weighs 82 pounds. Slides for
mounting the drive in a rack are included with drives that are not ordered with the optional
enclosure.

TAPE PATH AND SERVICE ACCESS
Access is available to the tape path and to the internal components of the tape drive. Access to the
tape path is often referred to as operator access, and to the internal components as service access.
Throughout this manual it will be taken for granted that the reader is a trained, qualified
technician who knows how to obtain access to the drive in both ways. The procedures are
explained below.
Operator Access
Rack-Mounted Drive
1. Release the rack latch located under the left side of the front panel. See Figure 1-2.
~1~/~_'~_1
-~~~~~
Figure 1-2. Location of Rack Latch and Cover Retainer Arm
2. Pull the tape drive out of the equipment rack.
3. Raise the top cover and place the cover retainer arm (Figure 1-2) in the slot next to
the tape path.
1-3

Reinstall the tape drive in the rack as follows:
1. Close the top cover.
2.
Press the slide locks inward and push the tape drive into the equipment rack.
Enclosured Drive
1. Open the lid of the enclosure fully. Push down on the front corners to release the
catchesbefore lifting the lid.
2. Raise
the top cover and place the cover retainer arm (Figure 1-2) in the slot next to
the tape path.
Close up the enclosure as follows:
1. Close
the topcover ofthe tape drive.
2. Release
the lid retainer arm on the right side of the enclosure lid and close the lid.
Service Access
Rack-Mounted Drive
1. Release the rack latch located under the leftside of the front panel (Figure 1-2).
2. Pull the tape drive out of the equipment rack.
3. Raise the top cover and place the cover retainer arm (Figure 1-2) in the slot next to
the tape path.
4. Loosen, but do not remove, the two screws on each side of the deck plate. See Figure
1-3.

5. Close the top cover.
6. Grasp the bottom of the front panel and lift it upward as far as it goes, then lower it
slowly until the latch in the support arm locks.
7. Insert the safety pin into the hole in the supportarm. See Figure 1-4.
1-5

Figure 1-4. Inserting Safety Pin Into Support Arm
Reinstall the tape drive in the rack as follows:
1. Remove
the safety pin from the support arm.
2. Grasp the bottom of the front panel and lift it upward to unlock the support arm
latch, then lower it slowly.
3. Raise
the top cover and place the cover retainer arm (Figure 1-2) in the slot next to
the tape path.
4. Tighten the two screws on each side of the deck plate to secure it to the chassis.
5. Close the top cover.
6. Press the slide locks inward and push the tape drive into the equipment rack.

Enciosured Drive
1. Open the lid of the enclosure fully. Push down on the front corners to release the
catches before liftingup the lid.
2. Raise the top cover and place the cover retainer arm (Figure 1-2) in the slot next to
the tape path.
3. Loosen, but do not remove, the two screws on each side of the deck plate. See Figure
1-3.
4. Close the top cover.
5. Grasp the bottom of the front panel and lift it upward as far as it goes, then lower it
slowly until the latch in the support arm locks.
6. Insert the safety pin into the hole in the supportarm. See Figure 1-4.
Close up
the enclosure as follows:
1. Remove the safetypinfrom the supportarm.
2. Grasp the bottom of the front panel and lift it upward to unlock the support arm
latch, then lower it slowly.
3. Raise the top cover and place the cover retainer arm (Figure 1-2) in the slot next to
the tape path.
3. Tighten the two screws on each side ofthe deck plate to secure it to the chassis.
4. Close the top cover of the tape drive.
