AUTION
:
When replacing any MXC300 card, the upper left
screw operates a microswitch. When this screw is open, it
indicates to the XDM-300 platform that the MXC300 is not
installed. This screw must be opened first when replacing an
MXC300 card.
3. Open the MXC300 upper left screw first, then the upper right screw, and
then the two lower screws.
4. Hold both extractor handles and pull them simultaneously outward until the
card is released from the backplane.
5. Keep holding the handles, and gently pull the card out of the shelf.
6. If necessary, transfer the NVM from the replaced MXC300 card to its
replacement (see Replacing the NVM on MXC300 cards).
7. Insert the rear end of the replacement card into the corresponding card
guides.
8. Push the card’s front panel with both hands until the extractor handles
attach to the panel.
9. Push the card in by holding both handles and pushing them simultaneously
inward, until the card mates the chassis connectors and is locked in place. If
you feel resistance before the connectors are mated, pull the card out and
repeat the procedure.
10. Close the card’s upper left screws first, then the upper right screw, and then
the two lower screws.

OTE
:
Make sure that all four screws in the MXC300 are
properly tightened. Failing to do so may result in improper
operation of the shelf.
If the FAIL (red), MAIN (blue), and TMU (orange) LEDs
blink simultaneously, the MXC is not mounted correctly or
not all four screws are properly locked.
