Element
Function
Local Console Disable
Two-position switch with amber indicator. Enables or
disables the Break key function for the local console
terminal. (The switch has no effect on the remote
console terminal. Full access privileges for the remote
operator are set by the local operator.)
When the switch is released (OFF, button out), the
Break key function is enabled and the indicator is dark
(unlit). The local operator may leave program I/O (PIO)
mode and enter console I/O (CIO) mode by pressing the
Break key. The console returns the >>> prompt.
When the switch is pressed in (ON), the Break key
function is disabled and the indicator is amber (lit). If
the Break key is pressed, the Break character is passed
to the operating software.
OS Running/Battery
Green indicator. When the indicator is green (lit), the
operating software is running. When the indicator is
dark (unlit), the operating software is not running (the
processor may be running the console firmware). When
the indicator is blinking, the system cabinet is running
on battery power.
Fault
Red indicator. The normal state of the indicator is dark
(unlit). When the indicator is blinking quickly, a logic
problem is present. When the indicator is blinking
slowly, a power system problem is present.
The MFI of the faulty device may also indicate the
fault. The normal state of an MFI is dark (reset).

Write Protect1
Two-position switches with amber indicators. The
switches enable or disable the associated drives for
writes by the software. When pressed in, a switch
disables writes to the drive and the indicator is amber
(lit). When released (button out), a switch enables
writes to the drive and the indicator is dark (unlit).
Ready/On Line1
Two-position switches with green indicators. The
switches enable or disable the associated drives for
acceptance of commands from software. When the
switch is released (button out), the drive is enabled.
When it is pressed in, the drive is disabled. When the
indicator is green (lit), the associated drive is up to
speed. When it is dark (unlit), the drive is not up to
speed or does not have power applied.

Write Protect and On Line switches control the RF-series disk drives and have no
effect on a TF-series tape drive. TF-series protection is set by a write-protect switch on the
TK tape cartridge.

Console Modes and Mode Change Commands
Console Operation
2–3
PIO Mode — Program I/O mode may be entered from either of the other
modes. To enter PIO mode, use one of these commands: SET TERMINAL
PROGRAM or PIO.
In PIO mode, all keyboard characters are passed to the operating
software. For a remote operator to use PIO mode, full access privileges
must be set by the local operator.
CIO Mode — Console I/O mode may be entered from PIO mode by
pressing the Break key. First, be sure the Local Console Disable switch on
the summary panel is released (button out). Then press the Break key on
the console terminal. If the Local Console Disable switch is set (button
in), the Break character is passed to the operating software like any other
character.
CIO mode may be entered from MIO mode by using the CIO command.
To recognize and process CIO mode console commands, the operating
software must be halted and the processor must be running the console
firmware. If you enter a CIO command (except for HALT) with the
operating software running, an error message returns.
CAUTION
To accept the CIO mode console commands, the processor must
be halted. Any attempt to access the system registers while the
system is running may cause the system to crash. All operators
with appropriate privileges may halt, start, or continue the
operating software from CIO mode.
MIO mode — Module I/O mode cannot be entered directly from PIO
mode. MIO mode may be entered only from CIO mode. To enter MIO
mode, use the MIO command.
MIO mode console commands affect only the console; the processor may
be running or halted. For a remote operator to use MIO mode, full access
privileges must be set by the local operator.

START [address]
Begins execution of the operating software
from the specified address or, if the address is
omitted, at the PC contents that were saved
on the previous HALT. If memory management
is enabled, the address is virtual. If memory
management is not enabled, the address is
physical.
TEST [/RBD]
Invokes the RBD monitor on the processor
module.
The TEST command is used only by qualified
maintenance personnel.
Zn
Invokes the RBD monitor on any system logic
module except for the primary system I/O
controller module, processor module, or a memory
module. The n specifies the slot ID number of an
approved I/O or adapter module in the backplane
of the local zone.

2.3 MIO Mode Console Command Summary
Table 2–3 briefly describes the MIO mode console commands.
Table 2–3 MIO Mode Console Command Summary
Command
Function
CIO
Changes the console mode from MIO to CIO.
DIALOUT
Invokes the console autonotification process.
The DIALOUT command is used only during
maintenance procedures.
DISABLE REMOTE
Disables all remote terminal console privileges.
Has the same function as the SET REMOTE OFF
command.
If the remote terminal is connected directly to
the system I/O module, the remote terminal
becomes inactive. If the remote connection is
made through a modem, the command does not
take effect until the remote terminal breaks the
connection. Dial-in access is also disabled.
ENABLE REMOTE [USER]
Enables remote terminal console privileges.
Without the USER option, this command has
the same function as the SET REMOTE FULL
command, enabling all privileges including dial-in
access through a modem.
With the USER option, this command has the
same function as the SET REMOTE SECURE
command, enabling access for the remote
operator, but only in PIO mode. If the remote
terminal is in any other mode, the command does
not take effect until the operator enters the PIO
mode.

I/O controller module. Has the same function as
the TEST/RBD command.
The RBD command is used only by qualified
maintenance personnel. The RBD command
must not be used while the operating system is
running.

Command Example
Function
BOOT:
>>> BOOT /R5:4 DIA7
General register R5 passes a value of 4 (hex) to the
virtual memory bootstrap (VMB) program, setting
bit <02>. Then the boot takes place from disk drive
unit 7.
>>> BOOT DIA0, DIB1, DIF0, DIG1
Four device specifiers are used, separated by
commas. The system selects one or more of the
paths to one or more of the boot devices. (See
Section 2.6.)
>>> BOOT MAIN
The boot takes place from the stored boot command
location called MAIN.
>>> BOOT
Without arguments, the boot takes place from the
stored boot command location called DEFAULT.
SET BOOT:
>>> SET /P BOOT MAIN /R5:4 DIA5
Opens a stored boot command location called MAIN
and stores the command both in volatile memory
and in EEPROM. (If the SET BOOT had been
issued without the /P qualifier, the command would
be stored in volatile memory only.)
>>> SET /P BOOT DEFAULT /R5:4 DIA7
Opens a stored boot command location called
DEFAULT and stores the command both in volatile
memory and in EEPROM.
>>> SET /P BOOT MAIN
Without arguments, the command clears the
location called MAIN.

2.6 BOOT Devices
The device specifier takes the form ddan where:
dd specifies the device type
MI is a TF-series tape drive
DI is an RF-series disk drive
EP is an Ethernet port
a specifies (using letters A through J) the zone and slot of the primary
system I/O controller module as shown in Figure 2–3. Figure 2–3 also
lists the correct module expansion sequence.
n specifies the decimal unit number of the boot device, which is the DSSI
node ID number selected by the backplane.

Figure 2–4 shows how the device specifiers select a system cabinet
drive or Ethernet port in an entry-level system. (The summary panel
controls the system cabinet drives as shown in Figure 1–3.) The drive
unit numbers correspond to DSSI bus addresses that are hardwired on
the drive backplanes. The left drive slot contains unit 5, and the right
drive slot contains unit 7. DSSI bus address 6 is used by the primary I/O
module in slot 2 of the logic backplanes. DSSI bus address 7 is used by
the secondary I/O module in slot 1.
Figure 2–5 shows how the device specifiers select an expander cabinet
drive in an expanded, dual access system. (The summary panel controls
the expander cabinet drives as shown in Figure 1–4.) The drive unit
numbers correspond to DSSI bus addresses that are hardwired on the
drive backplanes. Units 0 through 4 are always carrier drives. Unit 5
may contain either a cannister drive or a carrier drive as an option. An
expander cabinet does not support drives in both unit 5 slots. There are
no system cabinet drives in an expanded, dual access system.
