Requirements and Precautions for Operating Cards
Do not contact cards with bare hands. Always wear ESD protection gloves or an ESD
protection wrist strap when operating cards.
When holding a card, put your hands on its panel, and do not touch any components or wires
on the card, or metal conductors in the socket.
All vacant slots in a subrack should be installed with dummy panels. When you unplug a
dummy panel, make sure that you plug it back in five minutes.
Use care when plugging a card. The card cannot be inserted if not properly oriented.
Cards are valuable and fragile. Please treat them with great care.
Prevent the circuit surfaces of cards from contacting each other to avoid shorting or
scratching.
If the unpacked card is a spare one, it will not be installed immediately. Pack the card
with its original ESD protection bag and put it in a dry and cool place, keeping it away
from sunlight and strong electromagnetic radiation sources.
