Cisco Compact Flash Memory Card, 1 GB MEM-RSP720-CF1G= User Manual

Be sure to observe the following warnings and safety precautions when you work on the router.

Hazardous voltage or energy is present on the backplane when the system is operating. Use caution 
when servicing. Statement 1034

Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF 
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, 
detach the end away from the unit first. Statement 1026

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into 
beams or view directly with optical instruments. Statement 1051

Blank faceplates and cover panels serve three important functions: they prevent exposure to 
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) 
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not 
operate the system unless all cards, faceplates, front covers, and rear covers are in place. 
Statement 1029 

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are 
improperly handled, results in complete or intermittent failures. The supervisor engine or route switch 
processor consists of printed circuit boards that are fixed in metal carriers. Electromagnetic interference 
(EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps 
to protect the boards from ESD, use a preventive antistatic strap during handling.

To prevent ESD damage, follow these guidelines whenever you handle supervisor engine or RSP 
modules and router components:

Always use an ESD wrist or ankle strap and ensure that it makes good skin contact. 

Connect the equipment end of the strap to an unfinished chassis surface.

When installing a component, use any available ejector levers or captive installation screws to 
properly seat the bus connectors in the backplane or midplane. These devices prevent accidental 
removal, provide proper grounding for the system, and help to ensure that bus connectors are 
properly seated.

When removing a component, use any available ejector levers or captive installation screws to 
release the bus connectors from the backplane or midplane.

Handle components by their handles or edges only; do not touch the printed circuit boards or 
connectors.

Place a removed component board-side-up on an antistatic surface or in a static-shielding container. 
If you plan to return the component to the factory, immediately place it in a static-shielding 
container.
