PS6000 Hardware Maintenance
Before installing a control module, make sure the firmware on the control
module's compact flash card matches the firmware running on the functioning
control module. See Maintaining Control Module Firmware on page 3-4.
Control modules are installed vertically in a PS6000 array, oriented as shown in
Figure 3-6.

Caution: Wear electrostatic protection when handling a control module. See
Using an Electrostatic Wrist Strap on page 1-5.
To install a control module:
1. Open the control module latches by squeezing together the release mechanism
for each latch and then rotating each latch outwards. See Figure 3-4.
2. Correctly orient the control module as shown in Figure 3-6, depending on
which slot you are installing it in.
3. Hold the latches and slide the control module into the slot until you feel
resistance.
4. Rotate each latch inward, while pushing the control module completely into
the slot. The latches will snap into place (Figure 3-7).
