Electrical Equipment Guidelines

•

Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.

•

Do not perform any action that creates a potential hazard to people or makes the equipment unsafe; carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

•

Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

•

Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. SIPs, SPAs, and processor modules comprise 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 board from ESD, use a preventive antistatic strap during handling.

•

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

•

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 carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.

•

Place a removed board component-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.

•

Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Laser/LED Safety

An optical single-mode transmitter uses a small laser to transmit the light signal to the network ring. Keep the transmit port covered whenever a cable is not connected to it. Although multimode transceivers typically use LEDs for transmission, it is good practice to keep open ports covered and avoid staring into open ports or apertures. The single-mode aperture port contains a laser warning label, as shown in Figure 3-1. The multimode aperture contains a Class 1 LED warning label, as shown in Figure 3-1. These warnings apply to SPAs and SFP modules that transmit signals via an optical carrier signal.


Warning	Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051
Waarschuwing	Losgekoppelde of losgeraakte glasvezels of aansluitingen kunnen onzichtbare laserstraling produceren. Kijk niet rechtstreeks in de straling en gebruik geen optische instrumenten rond deze glasvezels of aansluitingen.
Varoitus	Irrotetuista kuiduista tai liittimist� voi tulla n�kym�t�nt� lasers�teily�. �l� tuijota s�teit� tai katso niit� suoraan optisilla v�lineill�.
Attention	Les fibres ou connecteurs d�branch�s risquent d'�mettre des rayonnements laser invisibles � l'œil. Ne regardez jamais directement les faisceaux laser � l'œil nu, ni d'ailleurs avec des instruments optiques.
Warnung	Unterbrochene Fasern oder Steckerverbindungenk�nnen unsichtbare Laserstrahlung abgeben. Blicken Sie weder mit blo�em Auge noch mit optischen Instrumenten direkt in Laserstrahlen.
Avvertenza	Le fibre ottiche ed i relativi connettori possono emettere radiazioni laser. I fasci di luce non devono mai essere osservati direttamente o attraverso strumenti ottici.
Advarsel	Det kan forekomme usynlig laserstr�ling fra fiber eller kontakter som er frakoblet. Stirr ikke direkte inn i str�lene eller se p� dem direkte gjennom et optisk instrument.
Aviso	Radia��o laser invis�vel pode ser emitida de conectores ou fibras desconectadas. N�o olhe diretamente para os feixes ou com instrumentos �pticos.
�Advertencia!	Es posible que las fibras desconectadas emitan radiaci�n l�ser invisible. No fije la vista en los rayos ni examine �stos con instrumentos �pticos.
Varning!	Osynlig laserstr�lning kan avges fr�n fr�nkopplade fibrer eller kontaktdon. Rikta inte blicken in i str�lar och titta aldrig direkt p� dem med hj�lp av optiska instrument.





Aviso	Radia��o laser invis�vel pode ser emitida a partir de fibras ou conectores desconectados. N�o fixe o olhar nos feixes e nem olhe diretamente com instrumentos �pticos.
Advarsel	Usynlig laserstr�ling kan forekomme fra brugte fibre eller stik. Stir ikke ind i str�ler eller direkte med optiske instrumenter.
