Installing the CPU Module
To install the CPU module:
Caution
Failure to exercise proper electrostatic discharge precautions (such as
wearing a grounded wrist strap) may reset the processor or damage
electronic components, resulting in interrupted operations.
When working on units located in a hazardous area (where explosive
gases may be present), make sure the area is in a non-hazardous state
before performing procedures. Performing these procedures in a
hazardous area could result in personal injury or property damage.
1.
Slide the CPU module into the slot.
2.
Press the CPU firmly into the slot, ensuring the ejector clips rest on
the module rail guides. The connectors at the back of the CPU
module fit securely into the connectors on the backplane.
3.
Place the CPU faceplate on the CPU.
4.
Tighten the two captive screws on the faceplate of the CPU module
firmly.
5.
Replace the wire channel cover.
6.
Return power to the DL8000.
