Disassembly Procedures
The T4500/T4600 Family computer has two basic types of cable connectors:
❑
Pressure Plate Connectors
❑
Normal Pin Connectors
To disconnect a Pressure Plate connector, pull the pressure plate’s side tabs straight out (toward the
cable) and slide the cable out of the connector. To connect a cable to a Pressure Plate connector,
make sure the pressure plate is open by fully extending the side tabs, then slide the cable into the
connector. Secure the cable in place by pushing the side tabs of the pressure plate in so the plate is
flush with the sides of the connector. Gently pull on the cable to make sure it is secure. If you pull
out the cable, connect it again making sure the pressure plate’s side tabs are fully extended 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.
