AST RESEARCH, INC. TECHNICAL BULLETIN #TB-0345 11/19/87
|
||
|
||
AST-5250/CLUSTER INSTALLATION
|
||
|
||
|
||
This technical bulletin is written as a guide for installation
|
||
of the AST-5250/Cluster.
|
||
|
||
|
||
I. THINGS TO CHECK BEFORE RUNNING CLUSTER EMULATION
|
||
|
||
A. On the master cluster bring up emulation for all the
|
||
sessions that will be used for the cluster. This can be
|
||
done by defining the sessions as Non-CLUSTER, under
|
||
STATION in the CFG5251 program, and running KERNEL and
|
||
APS without CLU5251. This will verify that those
|
||
sessions are available and correctly configured on the
|
||
host.
|
||
|
||
B. Correctly install the Cluster Adapter Board. Ensure the
|
||
hardware settings (IRQ, I/O address) do not conflict
|
||
with other devices in the computer.
|
||
|
||
1. Switch Bank 1 (SW1) and Switch Bank 2 (SW2), the IRQ
|
||
switch settings, must be set to use a unique IRQ.
|
||
|
||
2. Switch Bank 3 (SW3) settings. SW3 3 must be on and
|
||
SW3 4 must be off. Settings for SW3 1 and SW3 2
|
||
depend on the type of computer used:
|
||
|
||
a. If a PC, PC compatible, AT or AT compatible
|
||
(80286) is used:
|
||
|
||
- Set SW3 1 off and 2 on for I/O address 2BF.
|
||
- Set SW3 1 off and 2 off for I/O address 1BF.
|
||
|
||
b. If an XT or XT compatible computer is used:
|
||
|
||
- Set SW3 1 off and 2 off for I/O address 1BF.
|
||
|
||
II. SETTING UP THE CLUSTER
|
||
|
||
A. Master Cluster: CFG5251 program configuration
|
||
1. Type CFG5251.
|
||
2. Answer YES to Master Cluster question.
|
||
3. Go into STATION.
|
||
|
||
a. Define sessions to be used by the master as DISPLAYs
|
||
or PRINTERs under the STATION option.
|
||
b. Define sessions to be distributed to slaves as
|
||
CLUSTER DISPLAYs or CLUSTER PRINTERs.
|
||
|
||
Give unique SESSION NAMEs for each CLUSTER session that
|
||
will be distributed. Make a note of these names and
|
||
their corresponding sessions numbers.
|
||
|
||
4. Go into CLUSTER
|
||
|
||
a. Enter the IRQ and I/O Address of the Cluster board
|
||
under their appropriate options - INTERRUPT and
|
||
I/O_ADR respectively.
|
||
b. Configure each individual port. These must be set
|
||
for all ports being used (maximum of 4 ports).
|
||
|
||
c. COMPORT configurations. These settings depend on
|
||
how the slave device is set. The most common
|
||
settings are:
|
||
|
||
BAUD=9600 for COM LINE=DEDICATED, or
|
||
BAUD=(speed of modem) for COM LINE=DIALUP,
|
||
|
||
DATA=8
|
||
STOP=1
|
||
PARITY=NONE
|
||
REMOTE DEVICE=device type of slave, either PC,
|
||
ASCII24 or ASCII25 (ASCII refers to "dumb-
|
||
terminals").
|
||
COM LINE=DIALUP for slaves using modems to
|
||
communicate to master.
|
||
COM LINE=DEDICATED for slaves using RS-232C
|
||
cables to communicate to master (must be null-
|
||
modem cables, as specified in the AST-5250/
|
||
Cluster User's Manual (part number 000428-001,
|
||
section A.3, page A-6).
|
||
|
||
The following applies only if REMOTE DEVICE=ASCII24
|
||
or ASCII25:
|
||
|
||
XON/XOFF=XON/XOFF setting of ASCII terminal
|
||
SESSION NAME=NONE
|
||
|
||
d. DIRECTORY settings. Enter a directory NAME for each
|
||
slave that will be using this session and port. For
|
||
example enter Alf for the NAME of directory listing
|
||
0. Alf must also be entered in the slave for
|
||
directory listing 0 if it will be using this session
|
||
and is attached to this port. Up to 19 directory
|
||
listings may be defined.
|
||
e. INITIALIZE option. If a modem will be used to
|
||
remotely dial into this master cluster, an
|
||
initialization string must be entered here.
|
||
|
||
Modem String
|
||
Hayes compatible 1200 baud ATE0Q0S0=1
|
||
Hayes compatible 2400 baud ATE0Q0S0=1&C1&D2
|
||
Microcom compatible ATE0Q0S0=1&C1&D2\J0
|
||
|
||
The purpose of this string is to set the modem into
|
||
autoanswer mode, inhibit command echo, enable result
|
||
codes back to the terminal, and set the modem to be
|
||
in direct mode with a set baud rate speed.
|
||
|
||
f. The EBCIDIC, ASCII, and TERMINAL options do not have
|
||
to be changed.
|
||
|
||
5. SAVE configurations and QUIT.
|
||
6. In DOS type KERNEL, CLU5251 and then APS. These
|
||
commands could also be put in a batch file.
|
||
|
||
B. Slave Cluster: CFG5251S program configuration
|
||
|
||
1. Type CFG5251S.
|
||
2. Answer NO to all initial questions.
|
||
3. Go into HARDWARE.
|
||
|
||
a. COMPORT configurations. All settings in this
|
||
selection: BAUD, DATA, STOP, PARITY, COM_PORT,
|
||
DEVICE, and COMLINE must be the same as the master
|
||
configurations for this particular port.
|
||
b. DIRECTORY configurations. Each directory NAME must
|
||
match the name on the master directory. For
|
||
example, if Alf was entered for the NAME of
|
||
directory listing 0 on the master then Alf must also
|
||
be entered for directory listing 0 on this slave.
|
||
If slave will be a DIALUP device (remote emulation,
|
||
using modems) the PHONE NUMBER of the master must
|
||
also be entered, remember to start the number with
|
||
the ATDT dial command.
|
||
c. INITIALIZE option. If a modem will be used to
|
||
remotely dial into the master cluster, an
|
||
initialization string must be entered here.
|
||
|
||
Modem String
|
||
Hayes compatible 1200 baud ATE0Q0S0=1
|
||
Hayes compatible 2400 baud ATE0Q0S0=1&C1&D2
|
||
Microcom compatible ATE0Q0S0=1&C1&D2\J0
|
||
|
||
The purpose of this string is to set the modem into
|
||
autoanswer mode, inhibit command echo, enable result
|
||
codes back to the terminal, and set the modem to be
|
||
in direct mode with a set baud rate speed.
|
||
4. Go into the STATION option.
|
||
|
||
a. Define all sessions to be used by this slave PC as
|
||
DISPLAYs or PRINTERs.
|
||
|
||
Ensure the session numbers and corresponding SESSION
|
||
NAMEs match the master cluster definitions, the name is
|
||
case dependent.
|
||
|
||
5. SAVE configurations and QUIT.
|
||
6. In DOS type KERNELSL and then APS. These commands
|
||
could also be put in a batch file.
|
