Guidelines to Handling the Controller and Line Cards
Please observe the following guidelines when handling controller cards,
Ethernet line cards, and expansion modules:
 The controller and line cards are hot swappable and can be
installed or removed while the chassis is powered on.
Caution
The expansion modules for the AT-SBx81XLEM Line Card are not
hot-swappable. You have to install the modules before installing the
line cards in the chassis. For instructions, refer to “Installing
Expansion Modules in AT-SBx81XLEM Ethernet Line Cards” on
page 152.

Always wear an anti-static device when handling the cards.
Caution
The electronic components on the devices can be damaged by
electro-static discharges (ESD). Follow the procedure in “Protecting
Against Electrostatic Discharge (ESD)” on page 124 to guard
against ESD damage when handling the devices.
 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 the 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
69 on page 145.
