Laser Warning Labels for Single-Mode Port

Warning

Invisible laser radiation may be emitted from the aperture ports of the single-mode products when no
fiber cable is connected. Avoid exposure and do not stare into open apertures.

Warning

Class 1 laser product.

The multimode aperture contains a Class 1 LED warning label, as shown in

Because invisible laser radiation may be emitted form the aperture of the port when no fiber cable is
connected, avoid exposure to radiation and do not stare into open apertures.

Warning

Class 1 LED product.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Electromagnetic interference (EMI)
shielding is an integral component of the line card. Cisco recommends using an ESD-preventive strap
whenever you are handling network equipment or one of its components.

The 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 an ESD connection socket on the router or to
bare metal on the chassis.

Handle SIPs by the captive installation screws, the provided handle, ejector levers, or the line card
metal carrier only; avoid touching the board or connector pins.

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

Avoid contact between the SIPs and clothing. The wrist strap only protects the board from ESD
voltages on the body; ESD voltages on clothing can still cause damage.
