Installing Your Hardware Components 101
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 discharge can damage integrated circuits or
semiconductors if you touch backplane connector pins. Follow
these guidelines when you handle the power supplies.
• Touch a grounded object to discharge static potential.
• Do not touch the backplane connector or connector pins.
• Do not touch circuit components inside the power supply.
• Use a static-safe work station if available.
• Keep the power supplies in their static-shield packaging
when not in use.
IMPORTANT
If the equipment is not installed and used as described in this
manual, the protection provided by the equipment may be
impaired.
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.
