reseat the controller module for approximately 15 minutes after initial
insertion. Performing any of these actions during ACS may damage the
controller and it will have to be replaced. See

1. Align the latch handles on the controller module so they form a 90 degree angle with the
module. Attempting to install the module with the handles extended beyond this point
may cause damage to the handles.
2. Slide the controller module into the slot until the back edge of the handles latch into the
frame. See Figure 112
3. Swing the handles inward until the front edge of the handles snap into the tabs.
4. Observe the LEDs to determine the status of the controller modules. If ACS occurs, the
fault LEDs may remain on until it completes. For more information on ACS, see
"Identifying When ACS is Being Performed"
5. Install the enclosure front cover by sliding the top edge of the cover up under the lip of
the chassis, then pushing the bottom in until the pins snap into the mounting holes.
Identifying When ACS is Being Performed
To determine if ACS has been initiated, observe the controller module's LEDs. The
controller module will go through a power-up sequence before starting ACS. ACS will begin
within 1 minute after inserting the controller module.
During ACS, both the controller enclosure's System Fault LED, located on the front of the
controller fan module, and the controller module's Fault LED (see
The 8 status LEDs on the controller module will go on one at a time, from right to left, until
all 8 LEDs are on. All 8 LEDs will then turn off, one at a time, from left to right. This
sequence will repeat until the ACS has completed. When the ACS has completed, the LEDs
will return their normal operational state.
Normal controller module operation is indicated by the controller module LEDs (see
Figure 114): the Controller Power LED on, Controller Fault LED off, Heartbeat LED
flashing, and all remaining status LEDs off. If the Power LED remains off or the Fault LED
comes on after a few seconds, make sure that the controller module is locked in place. If
