Rack Mounting an MGX 8230
Step 1 Insert a the small flat head screwdriver into the lever slot and press until the latch springs open
(approximately 10°).
There are two levers on the left and right side for single height cards, or top and bottom on double-height
cards.
Step 2 Pull/rotate the insertion/extractor lever to disconnect the card from the backplane.
Caution When extracting a front card, keep the card level until it is completely extracted from the chassis. Do
not allow the front cards to drop against the cards below them. This could damage components on
the cards.
Step 3 Gently pull the card out of the card cage. Keep it level and make sure that the card does not hit the one
beneath it.
Remove the Back Cards
Back cards are retained with two captive screws: one at the top of the faceplate and one at the bottom of
the faceplate.
To remove a back card:
Step 1 Label and remove any cables connected to the back card.
Step 2 Use a screwdriver (flat or phillips as applicable) to undo the two retaining screws in the back card’s
faceplate.
Step 3 Pull both of the two extractor levers out to the horizontal position, this will start the removal of the card.
Step 4 Gently pull the card out of the card cage.

install it. Two installers can support and maneuver the MGX 8230 while a third secures it to the rack.
