Mounting Quantum Modules
Original instructions
Overview
Quantum modules can be inserted into any slot of any rack. Although Power supply modules should be installed in the first or last slots, to have a cooling effect. The modules can be removed under power (hot swapped) without damaging modules or the rack.
Refer to the following figures and procedure when mounting modules.
NOTE: To provide EMC level, the mounting area of the CPU has to provide metallic contact. Therefore remove any labels in the affected area and clean the surface using solvent. The Quantum PLC enclosures and terminal strips are made of polycarbonates. This material can be damaged by strong alkalis and various hydrocarbons, esters, halogens and ketones in combination with heat. Common products containing these include detergents, PVC products, petroleum products, pesticides, disinfectants, paint removers, and spray paints. Use care in selecting and using cleaning solvents..
CAUTION
POSSIBILITY OF MODULE DAMAGE
The inappropriate use of solvents, cutting oils, bug sprays and similar chemicals may cause the breakdown of module cases or terminal blocks.
Failure to follow these instructions can result in injury or equipment damage.
Hot Swap Precautions
WARNING
UNEXPECTED SYSTEM BEHAVIOR - CPU HOT SWAP CONSEQUENCES
Do not Hot Swap Quantum CPU.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Unplugging and re-plugging the Quantum CPU when the rack is under power is not recommended. You are strongly advised to shut the power down before attempting to remove the CPU for any reason.
CAUTION
UNINTENDED EQUIPMENT OPERATION
Hot swapping an I/O module can generate an error code causing the module to stop functioning.
Failure to follow these instructions can result in injury or equipment damage.
