1.6 Installing the rear-mount rear-most chassis
1. Make sure that the power switch at the rear of the chassis is in the OFF position.
2. Locate the 120 Vac power socket and the 2-pin 12 Vdc socket at the rear of the chassis.
3. Tip the front-most chassis outward, pivoting on the hinge at the bottom of the mounting
bracket. Do not allow the wiring to support the chassis.
4. Insert the replacement chassis into the mounting bracket.
WARNING! Voltages hazardous to personnel and equipment are present—be careful not to
contact the energized terminal blocks on the compartment walls.
5. Install the 120 Vac power cable by pushing it firmly into the socket.
6. Connect the 2-pin plug by inserting it into the socket until it clicks into place.
7. Install two mounting bolts and star washers into the replacement chassis tabs nearest the
bracket hinge.
8. Tip the chassis back into the vertical position. Hold down the cables at the rear of each
chassis to avoid snagging them on the stationary portion of the mounting bracket.
9. Install four mounting bolts and star washers into the chassis tab holes opposite the bracket
hinge. Make sure they are fully tightened.
10. Reconnect the two Ethernet cables into the CPU card according to the markings on the
cable ends.
11. Reconnect the synch clock cable to PORT 0 (CPU A) or to COM 2 (CPU B).
12. Turn on power to the CPU and chassis using the power switch. The indicators at the front of
the CPU should light.
13. Close the instrument compartment.
14. When the CPU has completed booting, verify its operation from the HMI's System Health
screen. At this time it may be desired to set the replaced CPU as the system default. (From
the Main Menu, click User Settings, and then click HMI Preferences.)
