Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
• Before beginning any procedures requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
• Disconnect all power and external cables before moving a chassis.
• Do not work alone if potentially hazardous conditions exist.
• Never assume that power has been disconnected from a circuit; always check.
• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
• Never install equipment that appears damaged.
• Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when
printed circuit boards are improperly handled and results in complete or intermittent failures
The network processing engine, input/output (I/O) controller, port adapters, and wireless modem cards
consist of a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI)
shielding, connectors, and a handle are integral components of the carrier. Handle the network
processing engine, I/O controller, port adapters, and wireless modem cards by their carrier edges and
handles; never touch the printed circuit board when handling either component.
Figure 7 shows the location of a printed circuit board when it is installed in a network processing engine,
I/O controller, or Cisco uBR7200 series modem card metal carrier. Do not touch the printed circuit board
when handling any of these components.
