Installing Cisco MDS 9100 Series Switch Rear-Facing into Cabinet
To install a Cisco MDS 9120 or 9140 Switch rear-facing into a cabinet using the rack-mount kit provided
with the switch (for cabinets with insufficient front-facing clearance), follow the steps in this section. If
you are installing a Cisco MDS 9134 Switch or a CiscoMDS 9124 Switch rear-facing into a cabinet
using the rack-mount kit provided, see “Installing a CiscoMDS 9134 Switch or a Cisco MDS 9124
Switch Rear-Facing into Cabinet” section on page2-17.
Step1 Install the slider rails in the rack:
a. Position one of the slider rails against the front rack-mounting rails and align the screw holes as
shown in Figure2-10. Then attach them using two 12-24 screws or two 10-32 screws, depending on
the rack rail thread type. For racks with square holes, first install the 12-24 cage nuts.
b. Repeat with the other slider rail on the other front side of the rack.
c. Use the tape measure and level to verify that the rails are horizontal and at the same height.
