2.9.5.9.1 Alarm Release Function Key
There are two system alarm release modes: automatic alarm release and manual
alarm release. If the system is in the automatic alarm release mode, the audible alarm
and the flashing alarm conditions are released 8 seconds after initialization. If the
system is in the manual alarm release mode, the audible alarm and flashing alarm
conditions are released by depressing the ALM RLS function key on the video terminal
keyboard. Minor audible alarms are retired after 8 seconds in either mode. Released
alarms and controls in effect remain in the alarm condition until the system has been
restored to normal operating condition. The alarm release mode is changed via a
maintenance command available on MCC display page 1400, or an input message.
Refer to 235-105-110, 5ESS Switch System Maintenance Requirements and Tools, for a
complete listing of MCC status indicators and their meanings.
2.9.5.9.2 Input Command Or Message Function Key
The command/message (CMD/MSG) function key configures the MCC to accept either
input CMDs or input MSGs. The key acts as a toggle and allows input in one mode or
the other. Personnel may switch between either mode after acknowledgment of the
previously entered message. Any unexecuted data in either area is lost if a switch is
made before an acknowledgment is received. The position of the cursor on the video
display indicates which input mode the MCC is in. The cursor resides in the input
message line area while in the MSG mode. If the MCC is in the CMD mode, the
cursor resides at the CMD entry area (at the top left of the control and display area).
Whenever the display is brought on line or a new page is selected, the input mode will
remain unchanged.
2.9.5.9.3 Normal Display Function Key
The NORM DISP function key places a page controlled from the emulated AM on the
display screen. The page displayed will be the previously displayed page. Depressing
the NORM DISP function key again will redraw a clean display without aborting any
processes in progress.
2.9.5.9.4 Emergency Action Display Function Key
The EMER DISP function key enables the emergency action mode and displays the
EAI page on the screen. See “Emergency Action Interface (EAI),” Section 2.9.5.2. This
page is used during a system emergency for system recovery functions. To exit the EAI
page, press the NORM DISP key.
2.9.5.9.5 Control + Enter Key
Press the Control + Enter key to switch between the UNIX system mode and the DRM
mode on the MCC display. The Enter key is located on the right side of the keyboard
in the numeric keypad section. Do not confuse the Enter key with the Return key on
the main keyboard.
2.9.5.9.6 Data Entry Functions
Most other keyboard keys are used in a normal fashion to enter numeric codes, input
messages, and alphanumeric responses to the system.
