Installation Procedures
Install the Cisco MGX 8950 Switch—Without a Mechanical Lift
Because of the risk of damage to the cards, modules, and backplane, Cisco strongly recommends the use
of a mechanical lift. Using a lift greatly simplifies the installation and reduces the risk of damage. See
"Install the Cisco MGX 8950 Switch—with a Mechanical Lift" section on page 3-29
information about installing the Cisco MGX 8950 switch with a mechanical lift.
If you are installing the Cisco MGX 8950 switch with a mechanical lift, proceed to the
Note

If a mechanical lift is not available for installation, the switch must be manually lifted into place. Since
the switch is shipped with all components pre-installed, you will have to remove the cards and modules
from the switch to easily lift it into the rack.
The following sections contain instructions for installing a switch without the use of a mechanical lift:

Single-height front cards have an extractor lever at the top of the faceplate to secure them into the card
cage. Double-height front cards have an extractor lever at both the top and the bottom of the faceplate.
