 There are three possible installation directions, and the mounting
 angle must be true within 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.

 Make shure to maintain the base temperature range of DE from 5*C to
 58*C.

 Cable requirements
 ------------------
 A characteristic impedance of 100   10% is recommended for the un-
 shielded twisted-pair ribbon cable. Characteristic impedance greater
 than 90  is preferred for the shielded cable. A minimum conductor
 size of 28 AWG shall be employed. It is recommended that the shielded
 cable be uses for connection outside the system cabinet.

 To minimize discontinuities and signal refelections, cables of dif-
 ferent impedance should not be used on the same bus. The maximum
 cable length is 6m. A cable length of 1m or more is recommended be-
 tween SCSI devices.

 Multi-drive connections
 -----------------------
 Host systems, IDDs, and other SCSI controllers can be connected
 (daisy-chained) to SCSI provided that the total number of SCSI
 devices connected does not exeed eigth.

 Terminator
 ----------
 Terminator is already installed in IDD at shipment. Remove the ter-
 minator if the IDD is not installed at beginning or ending position
 of SCSI cable.

 External LED Connector
 -----------------------
 The user can connect the external LED to the drive if necessary. The
 external LED is connected to CN6 on the PCA.

 AC line noise
 -------------
 To eliminate AC line noise, a noise filter should be incorporated in
 the AC input terminal of the drvie power supply.
 Attenuation characteristics: 40dB or greater at 10MHz
 Circuit configuration:       T type

 24KB data buffer
 -----------------
 To improve system throughput, the IDD contains a 24KB ring buffer.

 SCSI bus configuration
 ----------------------
 Up to eight SCSI devices can be connected to the SCSI bus, with any
 combination of the SCSI devices that operate as initiator and that
 operate as target.

 Each SCSI device on the bus has its own unique address (SCSI-ID: #n).
 For input/output operation, a peripheral device attached to the SCSI
 bus that operates as target is addressed in unit called as logical
 unit. A unique address (LUN: logical unit number) is assigned for
 each logical unit.

   | Host system +--+Host Adapter +-------+---+ IDD      |(fixed)
   |             |  |  ID #7      |       |   |   ID #0  |

                                          |   +------------+

 Mean Time Between Failures (MTBF)
 ---------------------------------
 The estimated MTBF of the IDD during its life time is 50.000 hours.

 Failure of the equipment means failure that requires repairs, adjust-
 ments or replacements. Mishandling by the operator, failures due to
 bad environmental conditions, power trouble, controller trouble,
 cable failures or other failures not caused by the equipment are not
 included.

 Mean Time To Repair (MTTR)
 --------------------------
 MTTR is the average time taken ba a well-trined 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 or the
 first 20.000 hours.

 Data security at power failure
 ------------------------------
 Integrity of the data on the disk is guaranteed against all forms of
 DC power failure except a power failure during a write operation.

 Tips & Hints about ICP controllers and other peripherals

 Tagged queues and Fujitsu M 26xx harddisks
 ------------------------------------------
 Fujitsu Harddisks of the M26XX series do not support the SCSI-II
 feature tagged queues. You should disable this feature in the
 initialize disks menue of the GDTSetup program. An inquiry command
 shows, that the harddisk supports tagged queues (this is why you can
 enable it in the GDTSetup) but this is not true as stated by Fujitsu
 Germany.
