Remove the Back Cards from an APS Assembly
Complete the following steps to remove back cards from an APS assembly and to remove the APS
connector from the switch.
Note An APS assembly consists of two back cards, a primary card and a secondary card, which are connected
by an APS connector (Cisco Part Number MGX-8850-APS-CON or MGX-APS-CON).
Caution Do not use a power screwdriver on captive screws.
Caution A rocking motion during connector mating can bend or damage the APS connector pins.
In the next steps, you will remove one of the back cards connect ed to the APS assembly.
Step1 Use the flat-head or Phillips tip of the 3-in-1 tool to loosen the two captive screws located on the top and
bottom of the back card faceplate.
Step2 Pull each of the two extractor levers, located at the top and bottom of the faceplate, out to the horizontal
position.
Step3 Pull evenly on the two extractor levers to remove the back card from the APS connector.
Step4 Repeat through Step 3 for the remaining back card in the APS connector. The APS connector is still
connected to the second back card when it is removed and comes out of the switch with the card.
Step5 Carefully separate the second back card from the APS connector by pulling it out with a straight motion.
Step6 Place the back cards and APS connector in antistatic bags or on an antistatic bench.
Step7 Repeat through Step 6 for any remaining APS assemblies.
Install the Switch in the Rack
Caution Even with the cards removed, the weight and bulk of the card cage mandate that three or more people
install it. Two installers can support and maneuver the switch while a third secures it to therack.
This section details the procedures necessary for installing the MG X 8850 or MGX 8850/B switch with
a mechanical lift in a 19-inch or 23-inch rack or a 19-inch cabinet.

Tip If the screw holes on the card cage are not aligned with the holes on the frame, place a flat-blade
screwdriver between the card cage and fan tray to raise the card cage. Insert the screws and tighten them.
Remove the screwdriver from between the fan tray and card cage.
