WARNING: Before you open the chassis, always unplug the

WARNING: Hazardous energy exists within the CoreBuilder
system. Use extreme caution when you install, remove, or replace
the EME or a memory card.
When the system is on, never insert metal objects such as a
screwdriver or a finger with jewelry into open module slots.
When the system is on, do not touch any connections within the
chassis with your hands or fingers. Do not insert metal objects into
the backplane.

ESD Safety Information

Electrostatic discharge (ESD) can damage components of the
system. ESD, which occurs when the EME or a memory card is
improperly handled, can cause complete or intermittent failures.
CAUTION: To prevent ESD-related damage:
Use proper grounding techniques.
Keep the memory card in its antistatic bag until you are ready
to inspect or install it.
When you handle the EME, follow these precautions:
Always handle the EME by the front panel only.
Do not touch the components, pins, leads, or solder
connections.
When you insert the EME into the module guides, do not twist
or otherwise force the module into the chassis.
Before you push the module into the chassis, make sure that
the module ejector handles are open.
When you slide the module into place, match the module
guides:
In the 16-slot chassis, match the upper and lower module
guides.
In the 7-slot chassis, match the left and right module guides.
