Installation and Programming
Install Controller Stratum 3 Clock Module
To install the clock module in the CX/CXi, and MXe:
1. Power down the controller (page 129).
2. Remove the controller cover (page 47).
3. Remove the screws from the clock module.
4. Remove the clock module.
5. Seat the new clock module onto the main board.
6. Replace the screws that you removed from the clock module.
7. Replace the top cover, and power up the controller (page 24).
Install Controller Hardware
Refer to “Add or Replace Controller FRUs” on page 166 for controller
hardware installation procedures.
Rack Mount the Controller
The rack-mount hardware secures the controller to the rack. The mounting
hardware is shipped with the controller.
MXe (Four-piece Bracket Installation)
1. Position a mounting bracket inside the rack frame at the desired
height. Fasten the mounting bracket to the front of the rack frame with
two screws—one in the top hole, the other in the bottom (see 1 on
Figure 15). Then do the same to fasten the other mounting bracket on
the other side of the rack frame at the same height.
2. Fasten the angle brackets on each side of the cabinet. Align the
brackets with the pre-drilled holes located near the front panel. Use
two screws to fasten each bracket (see 2 on Figure 15).
3. Set the controller cabinet onto the mounting brackets and slide the
controller cabinet into the cabinet (see 3 on Figure 15).
4. Fasten the angle brackets to the rack frame. Install two screws in each
bracket (see 4 on Figure 15).
Note: The other controllers use the Stratum 3 Clock, but in each case, the
clock is embedded and is not field replaceable. The MXe Server does not
use a Stratum 3 Clock.
