Chapter 2 Preparing for Installation
Safety and Compliance
Following are guidelines for preventing ESD damage:
• Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
Connect the equipment end of the connection cord to bare metal on the router chassis. (See
Figure 2-1.)
• Attach an ESD-preventive wrist strap to your wrist, and to the chassis or to a bare metal surface.
(See Figure 2-1.)
• The wrist strap protects equipment from ESD voltages on the body only; ESD voltages on clothing
can still cause damage to electronic components.
Caution To avoid ESD damage to the equipment, periodically check the resistance value of the
ESD-preventive wrist strap. The resistance measurement should be between 1 and 10 megohms
(Mohms).

When installing the card, confirm that the card is fully seated in the midplane and tighten the
spring-loaded screws. These screws prevent accidental removal, provide proper grounding for the
system, and help ensure that the connectors are seated in the midplane. (See Figure 2-1 and the
“Figure 3-6Disconnecting the Optical Interface Cable” section on page 3-6.)
• When removing the card, use the spring-loaded screws to unseat the card connector from the
midplane. (See Figure 3-10 and the “Figure 3-6Disconnecting the Optical Interface Cable” section
on page 3-6.)
• Handle the card by the spring-loaded screws only; avoid touching the board or connector pins.
• Place the card board-side-up on an antistatic surface or in a static shielding bag. If you plan to return
the card to the factory, immediately place it in a static shielding bag.
• Avoid contact between the card and clothing. The wrist strap protects the board only from ESD
voltages on the body; ESD voltages on clothing can still cause damage.
