This chapter shows you how to install the following hardware components: • your processor • modules • your memory module • your power supply • your chassis interconnect cable Installing Your Processor The processor always occupies the first slot of the first chassis. You can only install one processor per system. ! ATTENTION: Never install, remove, or wire any module while power is applied. Also, do not expose processor modules to surfaces or other areas that may typically hold an electrostatic charge. Electrostatic charges can alter or destroy memory. Important: If your processor has a battery — the battery is an option for the SLC 5/01 (1747-L511) processor — make sure it is connected before installing your processor into the chassis. This provides memory backup for your processor should the controller power supply fail. Publication 1747-6.2
6–2 Installing Your Hardware Components Installing Modules The following explains how to install your modules. 1. Align circuit board of the module with card guide in the chassis. Retainer Clip Circuit Board Side View Retainer Clip 2. Gently slide the module in until both top and bottom retainer clips are secured. 19527 3. Install a wire tie to secure your wiring and keep it neat. (If you feed the tie into one hole, it will be routed back out through the other.) 4. Cover any unused slots with card slot fillers (Catalog Number 1746-N2) to keep the chassis free from debris and dust. 5. To remove the module, press the retaining clips at the top and bottom of the module and slide the module out. Publication 1747-6.2
