2.1 GENERAL
CHAPTER 2
OPERATION
This chapter describes system indicators, control switch functions, and how to boot the VMS operating
system from the console terminal. It also provides procedures for setting up and operating the following
subsystems:
• LA120 and LA100 console terminals
• RL02, R80, RA80, RA81 and RA60 disk drives
• TU80 tape drive.
2.2 CPU CONTROL AND INDICATORS
Figure 2-1 shows both VAX-11/730 system CPU controls and indicators and the TU58 tape drive
cartridge slots. The VAX-11/730 System 1 and 2 control panel contains only one TU58 tape drive
cartridge slot. The second cartridge slot is located on the right side of the CPU and is accessed when the
CPU drawer is slightly extended from the cabinet. This slot normally contains the console tape cartridge.
The VAX-11/730 SBB control panel contains both TU38 tape drive cartridge slots. The slot marked "1"
normally contains the console tape cartridge.

2.2.1 The Console Subsystem
The VAX-11/730 CPU features a console subsystem that allows the CPU to be controlled- from the
console terminal. The console terminal serves as the local input device to the system and takes the place of
most of the switches and indicators normally found on a CPU front panel.
2.2.2 CPU Indicators
Four LED indicators display the CPU operating conditions described in Table 2-1.

Function
ON -The CPU is in program mode and is running the main memory
program.
OFF -The main memory program is halted and the CPU is in console
mode. The console subsystem responds to console commands typed on the
console keyboard.
ON -All de power supply voltages are within specified limits.
Blinking -One or more de supply voltages is out of tolerance.
Indicates condition of battery backup unit (BBU).

Blinking slowly: BBU charging.
Blinking fast: BBU discharging.
Off: BBU not present or not active.
Blinking -The CPU key switch is in the REMOTE position to establish
communication with the remote diagnostic operator. This indicator works
only when the sytem is equipped with the remote diagnostic option.
ON -The CPU is under the control of the remote diagnostic operator.
Local control may then be reenabled by commands from the remote
operator.
OFF -Normal operation.
2.2.3 CPU Power and Control Switch
The key-operated power switch has six positions that have the functions described in Table 2-2.
2.2.4 AUTO REST ART Switch
The console subsystem tests the ON and OFF state of the switch following a system power-up sequence or
a program halt condition. A general description of the functions is provided in Table 2-3.
2.2.5 TU58 Cassette Tape Drives
There are two tape motion indicators, one on either side of the external tape cartridge slot shown in Figure
2-1.

Table 2-2 CPU Power Switch Functions
Function
Switched ac power is turned off inside the system cabinet (unswitched
power is still applied).
Minimum CPU power is applied to maintain all data in the console,
writeable control store (WCS), main memory, and time-of-year clock.
This is the normal ON position. All power is applied and the operator
controls the system from the console terminal as follows.
Console mode ~ The operator performs console commands.
Program mode -The operator communicates with the system program. A
CTRL/P character is not passed to the program, but halts the program
and returns the CPU to the console mode.
CPU functions are the same as for the LOCAL position except as follows.
Console mode -Inputs from the console keyboard are ignored. The
momentary BOOT position of the Auto Restart switch is also ignored.
Program mode - A CTRL/P character is passed to the program and does
not halt the CPU.
REMOTE is used to establish and hold communications with a remote
operator at a DIGIT AL diagnostic center (DDC). The local operator has
control of the system until the remote operator takes control. The local
keyboard may then be reenabled by the remote operator to allow the local
operator to have different levels of access.
CPU functions for the local operator are the same as for the LOCAL
position depending on the level of access granted by the remote operator.
Console mode -The local operator may perform console commands.
Program mode - A CTRL/P halts the program and returns the CPU to
the console mode.
CPU functions are the same as for the REMOTE position, depending on
the level of access granted by the remote operator.
Console mode -Inputs from the local keyboard are ignored. The momen-
tary BOOT position of the Auto Restart switch is also ignored.
Program mode - A CTRL/P character is passed to the program and does
not halt the CPU.

OFF
ON
The CPU is placed in the console mode after the microcode is loaded from
the TU58 on a power-up sequence or when a running program is halted.
The operator may perform console commands or may bootstrap and run
programs using the console terminal keyboard.
After the microcode is loaded on a power-up sequence, the console subsys-
tem loads and executes the default bootstrap command file
DEFBOO.CMD from the TU58.
The first bootstrap command file then loads the main bootstrap program
VMB.EXE from the TU58 to memory. VMB.EXE then loads and starts
the VAX/VMS operating system.
BOOT Moving the switch to the momentary BOOT position, when
in the console
mode idle state, loads the default bootstrap command file DEFBOO.CMD
and begins the same sequence of events as for the ON position.
Following the ON or BOOT sequence above, when the system is running
in the program mode, the switch is left in the ON position to enable the
warm restart facility if any of the following actions are desired.
• A system reboot following a power loss
• Program recovery following a program halt
• A warm restart of the current program when the CPU power switch
is turned from STD BY to LOCAL. (The current program remains
intact if the CPU power switch is turned only to STD BY and not to
OFF.)
The EXT (unit 0) indicator is lit when the external drive is in motion. The external drive allows the
operator to:
• Load or store user-created programs or data
• Bootstrap, load, or update the software, diagnostics, or microcode
• Build the system disk.
The INT (unit 1) indicator is lit when the internal drive is in motion. The console tape normally remains
inserted in the internal drive located on the right side of the CPU chassis. If system power has been
completely removed, console and writeable control store (WCS) data is loaded from the console tape when
system power is restored.
The console defaults to the internal drive if no drive is specified by the operator. It may also be used by the
operator with, or as backup for, the external drive.

2.2.5.1 Cartridge Loading and Unloading -To insert a cartridge, hold it with the label side up and the
baseplate down as shown in Figure 2-2. Align it with the grooves in the slot, slide it straight in, and seat it
firmly. To remove the cartridge, pull it straight out. Be careful not to remove the cartridge while the tape
motion indicator is on, or data may be lost.
2.2.5.2 RECORD Tab -Each cartridge has a movable RECORD tab as shown in Figure 2-2. The TU58
write circuitry is disabled when the tab is moved away from the edge of the cartridge. This prevents
unintended write operations.
When the RECORD tab is moved toward the edge of the cartridge, it closes a switch in the drive that
allows data to be written. The operator should be sure that system or program tapes have backup copies
before loading them with the tab set in the RECORD position.
The RECORD tab may be removed for long-term write protection. On metal-base cartridges, lift the tab
with a fingernail under the protruding end. Replace it by placing it in its slot and pressing it in until it
snaps. On plastic-base cartridges, pry the tab from the back edge slightly, then lift it from the front.
Replace it by placing it in the slot and pressing forward and down.

Function
The LA120 terminal is on-line. The terminal transmits keyboard charac-
ters to the CPU and receives printer characters. Characters typed on the
keyboard are transmitted back to the printer by the program.
The LA120 keyboard is locally connected to the printer. The terminal is
off-line and does not receive or transmit characters.
The alternate character set is enabled (in terminals optionally equipped
with a foreign language character set).
Data transmission is enabled (Clear To Send).
The modem is in data mode (Data Set Ready).
Blinks when the LA 120 terminal is in the set-up mode.
Blinks when the LA 120 terminal is disabled by one of the following
conditions.
• The printer is out of paper
• The cover is open
• The print head is jammed
During normal operation, indicates the horizontal column position of the
print head. In set-up mode, the vertical line position is also indicated by
pressing the SHIFT key.
*Used in terminals connected to a modem.
2.3.2 LA120 Control Keys
There are several control keys that do not transmit characters. Their functions are described in Table 2-5.
2.3.3 LA120 Set-up Functions
The terminal should be placed in the local mode to avoid transmitting characters while making changes in
the set-up mode.
