3.1 Passive backplane
Before detaching the backplane, you must slide out the work drawer. Fol-
low these steps:
1.
Switch off the power, and detach the main power cord.
2.
Detach the work drawer from the AWS-8248 unit. (See Fig. 2-1.)
3.
Slide the work drawer out as far as it will go. Detach the holding
clamp, cables and all the installed cards.
4.
Detach the P8 and P9 power connectors by pulling them down.
Unscrew the seven screws and detach the backplane.Our worksta-
tions are equipped with programmable function keys (macro keys)
that greatly enhance the operator interface. Macros, which are far
more powerful than batch files, automate the most commonly used
input sequences. They extended their functional reach to within
application programs.(See Fig. 3-1.)
