Please observe the following guidelines when handling the controller and
Ethernet line cards:
The cards are hot swappable and can be installed or removed
while the chassis is powered on.
Warning
The expansion modules for the AT-SBx81XLEM Line Card are not
hot swappable, You must remove the line card from the chassis
before installing or removing an expansion module.
Always wear an anti-static device when handling the cards.
Caution
The electronic components on the controller and line cards can be
damaged by electro-static discharges (ESD). Follow the procedure
in "Protecting Against Electrostatic Discharge (ESD)" on page 110 to
guard against ESD damage when unpacking and installing the line
cards.
Hold a card by its faceplate and edges.
Never touch the electronic components on the top or bottom of a
card.
To avoid damaging the components on the bottom of a card, do
not set it down on a table or desk. If you need to set down a card,
return it to its anti-static bag and packaging container.
Do not remove a card from its anti-static bag until you are ready to
install it in the chassis.
If you need to remove a card from the chassis, immediately return
it in its anti-static bag and packaging container.
Never hold or lift a controller card by the handles on the front
faceplate. You might bend or damage the handles.
Caution
You must keep a controller or Ethernet line card level as you slide it
into or out of the chassis. You might damage the components on the
top or bottom of a card if you slide it at an angle. Refer to Figure 64
on page 131.
