Laser Safety - Cisco Gigabit Switch Router 12008 Installation And Configuration Manual

Safety Recommendations
•
Always place a card component side up on an antistatic surface, in an antistatic card
rack, or in a static-shielding bag. If you are returning a card to the factory, immediately
place it in a static-shielding bag.
•
Use the ejector levers to properly seat the card connectors in the backplane when you
are installing line cards or the RP; tighten both captive installation screws on the card.
These screws prevent accidental removal, provide proper grounding for the system, and
help to ensure that the card connector is seated in the backplane.
•
Use the ejector levers to unseat the card connector from the backplane when removing
a line card or the RP.
Slowly pull the metal card carrier out of the slot with one hand, placing your other hand
along the bottom of the card carrier to support the card's weight and guide it straight out
of the slot.
•
Handle line cards or the RP only by the edges of the metal card carrier; avoid touching
the board or the connector pins.
Caution
resistance measurement should be between 1 and 10 megohms.
