3.
Make sure the working environment is free from the following elements whether
you are using or storing the 610CT:
Dust and contaminates
Static electricity
Extreme heat, cold, and humidity
4.
Make sure the FRU you are replacing is causing the abnormal operation by per-
forming the necessary diagnostics tests described in this manual.
5.
Do not perform any operations that are not necessary and use only the described
procedures for disassembling and installing FRUs in the 610CT.
6.
After removing parts from the computer, place them in a safe place away from the
computer so they will not be damaged and will not interfere with your work.
7.
You will remove and replace many screws when you disassemble the 610CT.
When you remove screws, make sure they are placed in a safe place and identified
with the correct parts.

After you have replaced an FRU make sure the 610CT is functioning properly by
performing the appropriate test on the FRU you have fixed or replaced.
Disassembly Procedures
The 610CT has two basic types of cable connectors:
Pressure Plate Connectors
Normal Pin Connectors
To disconnect a Pressure Plate connector, lift up the tabs on either side of the connector's
plastic pressure plate and slide the cable out of the connector. To connect the cable to a
Pressure Plate connector, make sure the pressure plate is fully lifted and slide the cable into
the connector. Secure the cable in place by pushing the sides of the pressure plate down so
the plate is flush with the sides of the connector. Gently pull on the cable to make sure the
cable is secure. If you pull out the connector, connect it again making sure the connector's
pressure plate is fully lifted when you insert the cable.
Standard pin connectors are used with all other cables. These connectors can be connected
and disconnected by simply pulling them apart or pushing them together.
