Computers may be powered up one at a time or all at once. Operator intervention
is not necessary during booting. With the front access model, a computer may
be selected at the local console by pressing the push-button for that computer
channel. The channel letter will then be shown on the alphanumeric display.
All other user consoles select computer channels through a keyboard sequence
described on the next page. The indicator lights (LEDs) over the push-buttons
will change to reflect the status of each attached computer or secondary
console. See the tables below.
