AUTION
You must properly shutdown the system and turn off the power switch on
the rear of the unit before removing a line card. Failure to do so could
cause file corruption or damage to the board or system.
2 Attach an ESD strap to your wrist and to the grounding connector at
the back of the unit before opening the appliance or removing any
card or module. Electro-Static Discharge, ESD, can damage the board
or system. Wear the ESD strap at all times while handling both old
and new cards and modules.
Note: The appliance must be plugged in to a properly grounded
outlet for the grounding connector to function.
3 Turn the card’s latching screws counter-clockwise until they pop out.
4 Pull both ejector latches out toward the sides of the line card. The card
disengages from the backplane and pops out of the slot slightly.
5 Remove the card from the unit. Be sure you handle it only by its
faceplace and the bottom metal plate.

ARNING
The heat sink and other electrical components on the top of the card may
be hot enough to cause burns. Handle the card only by its face plate and
the bottom metal plate. Do not touch the heat sink or other electrical
components on the top of the card. Do not place paper or other flammable
materials on the top of the card.
W
ARNING
To prevent personal injury or damage to the board or system, do not insert
your fingers, tools, or anything else into the appliance when a card is
removed. The fan blades inside the appliance may continue to spin when a
line card is removed. Do not leave the appliance unattended when a card
or module is removed.
