ATLAS 890 AC POWER SUPPLY
Power supplied is the correct voltage
and polarity; backplane and hot
insertion voltages correct.
A temperature or power failure
condition is active.
Red (fast blink)
Power failure condition active. A
power failure condition takes
precedence over other failures; both a
power and temperature failure
condition results in a fast blinking
Amber (slow blink)
If power is applied to the ATLAS 890 unit and there is no
active Controller, the front panel LEDs will be in an
indeterminate state. The controller must complete its power
up sequence before the LEDs are valid.
The ATLAS 890 AC Power Supply furnishes the voltages
necessary for proper backplane operation. The AC Power
Supply also provides the voltages that enable hot insertion of
the option cards and system controller modules.
Double pole/neutral fusing.

1. Remove the cover plates from option slots 16 and 17 by
removing the two screws.
2. Ensure there is no power cord attached to the power
3. Insert power supply into ATLAS 890 option slot 16.
(Redundant AC power supply will occupy slots 14 and 15.)
4. Secure the thumbscrews at both edges of the power
supply. Tighten with a screwdriver.
5. Connect the power cord to the unit.
6. Switch the power supply ON.
7. To view the status of the AC Power Supply, use the
System Controller terminal menus (see ATLAS 890
