4.5 Removing an Interface Card
NOTE: This procedure must be followed to change the hardware strapping on an
interface card that has already been installed. (For interface card installation,
see
“Installing an Interface Card” on page 4-18 .)
CAUTION: Interface cards must be removed with care. Use ESD procedure at all
times.
To remove an interface card:
1. At the rear of the SDM-9220/9230 chassis, turn the power switch OFF by pushing it
to 0 , and unplug the power cord from the power supply.
WARNING: To avoid electrical shock and damage to the unit, make sure that the
unit is disconnected from its power source before you access any of its internal
components.
NOTE: You do not need to disconnect any cables that may be connected to the data
(WAN/user), LAN or console ports, or to other interface cards that may be
already installed.
2. Using a small, non-magnetized Phillips screwdriver, loosen the 2 captive screws that
hold the faceplate of the interface card onto the chassis wall.
3. Pull the interface card horizontally out of the slot using the tips of your fingers. To
disengage the interface card from the connector on the main board, you may need to
use a small,
non-magnetized flat-head screwdriver to gently pry the faceplate of the
interface card away from the chassis wall. If you must do this, be very careful that you
do not apply too much force on the interface card or its faceplate .
CAUTION: Do not expose the interface card or the SDM-9220/9230 unit to a
magnetic field or electrostatic charge at any time. Damage to their components
could result.
