Physical Installation

2.1 Site Planning
Follow the requirements in this section to prepare a site for the SA106
and TA867 subsystems.

2.1.1 Space Requirements
Leave enough space to remove the magazine tape subsystem from the
front of the cabinet (about 1 meter). Also leave enough space to remove
the SCSI/STI adapter assembly from the rear of the cabinet (about 1
meter).

2.1.2 Power Requirements
The subsystem can operate from 100 to 120 Vac at 60 Hz, or from 220 to
240 Vac at 50 Hz.

2.1.3 Environmental Requirements
The SA106 and TA867 conform to a modified class A environment (general
offices and workstations).
•

When the SA106 and TA867 are operating, the temperature should
range from 10°C to 40°C with relative humidity of 20 to 80%
noncondensing

•

When the SA106 and TA867 are not operating, the temperature
should range from –40°C to 66°C with relative humidity of 10 to 90%

2–2 Physical Installation

2.1.4 STI Interconnect Cabling
1. Connect the STI cable(s) to the rear of the SA106 chassis (Figure 2–1).
Each cable is secured with two captive screws. For cabling of the
TA867, see the documentation in the TA867 Kit.
2. Connect the HSC cable(s) to the K.SI module.
NOTE
K.STI modules do not support the SA106 and TA867 storage
subsystems.
3. Assign a unique unit number to the magazine tape subsystem. The
unit number is a decimal number between 0 and 255. To assign the
unit number, use the push buttons on the side of the unit number
switch to increase or decrease the number.
Transport numbers are always assigned in groups of four to each
formatter. Transports are assigned the following unit numbers:
•

0 to 3 for the first formatter

•

4 to 7 on the second formatter of a system with two or more
formatters

•

8 to 11 on the third formatter, and so on

4. Place a decal identifying the transport unit number just below the
loader fault indicator on the magazine tape subsystem .

2.1.5 STI Cables
The SA106 storage subsystem will contain one, 25-foot STI cable. You will
need a second cable for dual applications.

Acceptance Testing

3.1 Power-on Self-test
See the Tx867 Series Magazine Tape Subsystem Owners Manual (EK–
TX867–OM) for information on power-on self-test (POST) for the magazine
tape subsystem.

3.2 Diagnostics
The two diagnostic tests for the SA106 and TA867 subsystems are
ILTAPE and ILEXER:
•

In-Line Tape Diagnostic (ILTAPE)–A canned sequence diagnostic
that tests the SA106 and TA867 functions by using the basic tape
commands.

•

In-Line Exerciser (ILEXER) — This diagnostic exercises from 1 to
10 units in any combination of disk and drives connected to an HSC.
Logic is tested by writing and reading predetermined data patterns
and recording modes.

ILTAPE and ILEXER are run from the HSC ASCII port. See the
appropriate HSC user documentation for more information.
To test the SA106 or TA867:
1. Run ILTAPE for three passes. No errors are allowed. (When both
STI ports are used, run ILTAPE through the second port for one pass
also.)
2. Run ILEXER for 15 minutes. (When both STI ports are used, run
ILEXER through the second port for 15 minutes also.)

4–2 Operation

Table 4–1 lists the function and state of each control/indicator:
Table 4–1 SA106 and TA867 Controls and Indicators
Control
/Indicator
Port Select A

Function/State
In the enable (in) position, PORT SELECT A allows the HSC to
access port A. Under microprogram control, the HSC can then
cause port A to go on line.
Placing Port Select A in the disable (out) position with port A on
line causes serious errors at the HSC.
Port Select A lights when port A is on line (ready to receive any
command or data).

Port Select B

The definition of Port Select B for port B is the same as the
definition of Port Select A for port A.

Fault

The fault indicator lights when a potentially fatal error has been
detected in the formatter. Even though an error has occurred, the
formatter still attempts to communicate with the HSC.
With a fatal error present, press the Fault switch to clear the
error.

Ready

The ready indicator lights after the SCSI/STI adapter successfully
completed its power-on self-tests (POST).

NOTE
The TA867 configuration will depend on your cabinet installation.
Controls and indicators on the SA106 and TA867 subsystems are
identical.
