Chapter 5 Installing the Cisco MGX Switch or Gateway
Installing the MGX 8950 Switch
Caution An APS assembly consists of two optical AXSM back cards, a primary card and a secondary card, which
are connected by an APS connector (Cisco Part Number MGX-APS-CON-8950).
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.
Step 1 Remove one of the back cards connected to the APS assembly.
a. 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.
b. Pull each of the two extractor levers, located at the top and bottom of the faceplate, out to the
horizontal position.
c. Pull evenly on the two extractor levers to remove the back card from the APS connector.
d. Repeat a through c 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.
Step 2 Carefully separate the second back card from the APS connector by pulling it out with a straight motion.
Step 3 Place the back cards and APS connector in antistatic bags or on an antistatic bench.
Step 4 Repeat through Step 3 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 MGX 8950 switch while a third secures it to
the rack.
This section details the procedures necessary for installing the MGX 8950 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.
Warning
Never attempt to lift the chassis with the handles on the power supplies, fan trays, or the switching
modules. These handles are not designed to support the weight of the chassis. Using them to lift or
support the chassis can result in severe damage to the equipment and serious bodily injury.
