March 3, 1980 3704/3705 Control Program LOAD initiates the control program load operation.
raddr is the real address of the 3704/3705 to be loaded.
ncpname is the name, defined by a
control program image to
specified by raddr. NAMENCP macro, of the
be loaded into the 3704/3705 3704/3705 EXECUTION OF THE NETWORK LOAD COMMAND The NETWORK LOAD command accesses the control program image using the information in the system name (DMKSNT) entry created by the NAMENCP macro. If the 3704/3705 specified in the command is not in an
"IPL Required" state at the time the is issued, the message:
DMKNET461R CTLR raddr IPL NOT REQUIRED; ENTER "YES" TO CONTINUE: appears at the terminal. If the reply to the message is other than
"yes", the command terminates without loading the 3704/3705. Otherwise, the loader bootstrap routines are written to the 3704/3705 and loading
starts. 'K/370 does not execute the "bring-up" test routines as a part
of the load process. If these tests are to be made, they must be run
from a virtual machine with the 3704/3705 dedicated. When the load of the centrol program image is complete, the command
processor verifies that the 3704/3705 configuration described by the
contrel program can be serviced by the VM/370 CP control blocks in
storage. SPECIAL CONSIDERATIONS FOR LOADING THE EP 3704/3705 CONTROL PROGRAM If a 3704/3705 Emulation Program is automatically reloaded after a 3704/3705 failure, the system may loop after the restart. The message
DKKRNH463I CTLR raddr UNIT CHECK; RESTART IN PROGRESS and two responses
CTLR raddr DUMP COMPLETE CTLR raddr ncpname LOAD COMPLETE indicate that the 3704/3705 has been reloaded. If the system loops
after the second response, you must reset all emulator lines from the 3704/3705 control panel.
If the automatic dump feature is not enabled, one of the messages DMKRNH462I CTLR raddr UNIT CHECK; IPL REQUIRED -- or --
DMKRNH4641 CTLR 'raddr' CC=3; DEPRESS 370X "LOAD" BUTTON Part 4. Generating the 3704/3705 Control Proqram 313

Page of GC20-1801-10 As Updated March 3, 1980 by TNL GN25-0776 3704/3705 Contrel Program indicates a 3704/3705 abnormal termination. The 3704/3705 Emulation Program must be reloaded via the NETWORK LOAD command. If the system
loops when an attempt is made to enable the lines, you must reset all
emulator lines from the 3704/3705 control panel.
The describes the procedure for resetting emulator lines from the 3704/3705 control panel.
Step 11. Logging On through the 3704/3705 Because a 3704/3705 can support emulator-mode lines and can also support
a variety of terminals, the procedure for logging on is sometimes
complicated. Use the following procedure to log on to VM/370. TURN THE POWER ON First, turn the power on for your terminal and wait 15 to 30 seconds.
CHECK FOR AN ONLINE MESSAGE Second, look for an online message at your terminal.
If one of the following messages appears at your terminal vm/370 online xxxxxx xxxxxx
or
xxxxxx xxxxxx vm/370 online
your terminal is a 2741 connected to VM/370 via a 2701/2702/2703 line or
via a 3704/3705 line in emUlation mode. You can proceed with the normal
logon procedure for your type of terminal, as described in the VMLll] If the message vm/370 online
appears at your terminal, your terminal is: I. A 1050, 3101, or CPT-TWX Model 33/35 terminal connected to VM/370 in EP mode.
You can proceed with the normal logon procedure for your terminal type.
This procedure is described in the 314 IBM VM/370 Planning and System Generation Guide
