There are three possible installation directions, and the mounting
angle must be 5* from the horizontal.
Ambient temperature
-------------------
The operating temperature range of the drive is specified at a dis-
tance of 3 cm from the drive.
Multi-drive connection
----------------------
In serial mode, up to 7 drives can be connected. The termination of
the control signals must be performed only at the last drive. The
terminator must be removed from all but the last drive. To connect
drives, the A cable (control signals) must be connectesd in series
and the B cables (R/W signals) in parallel.
+----------+A cable A +---------+ | +-----------*------+ Drive 1 | | C |B cable | B | | | O +-----------|------+ | | N | | +---------+ | T | | | R | | A +---------+ | O | *------+ Drive 2 | | L |B cable | B | | | L +-----------|------+ | | E | | +---------+ | R | | | | | | | | A +---------+ | | +------XXX TERM | | |B cable B | | | +------------------+ Drive n | | | +---------+ +----------+ Cable length should not exceed 3m!
AC line noise
-------------
To eliminate AC line noise, a noise filter of the specifications
given below should be incorporated in the AC input terminal of the
drive power supply.
Attenuation characteristics: 40 dB or greater at 10MHz
Mean Time Between Failures (MTBF)
---------------------------------
The estimated MTBF of the drive during its life time is 30.000 hours
after an initial 3-month period.
Mean Time To Repair (MTTR)
--------------------------
MTTR is the average time taken by a well-trained service mechanic to
diagnose and repair a drive malfunction. The drive is designed for
a MTTR of 30 minutes or less.
Service life
------------
Overhaul of the drive is not required for the first five years.
Power loss
----------
Integrity of the data on the disk is guaranteed against all forms of
abnormal power failure except a power failure during writing.

Media defects
=============
Cylinder 0, Head 0 and 1 are defect free.
The maximum defect length is 32 Byte.
All defects are recorded on a label on the media per the ESDI speci-
fication. When the unit leaves the factory, a printed media defect
list of each drive is sent with it.
