Installing the Cisco MDS 9124V-K9 Switch
Step 1
Install two rack-mount brackets to the switch as follows:
a. Position a rack-mount bracket so that three of its screw holes are aligned to the screw holes on the side of the chassis.
You can align any three of the holes in the rack-mount bracket to three of the screw holes on the side of the chassis.
The holes that you use depend on the requirements of your rack and the amount of clearance. For more information
on clearance, see the
b. You can install the rack-mount bracket either at the front or rear of the chassis. The choice is determined by which
end of the chassis will be inserted into the rack first. If the rear end of the chassis is to be inserted first, then mount
the brackets on the front of the chassis, and vice versa.

c. Secure the rack-mount bracket to the chassis using the three M4 screws and tighten each screw to 12 in-lb (1.36 N·m)
of torque.
d. Repeat Step 1 for the other rack-mount bracket on the other side of the switch, and be sure to position it in the same
distance from the front of the switch.
Step 2 If you are installing the chassis into an ungrounded rack, you must attach a customer-supplied grounding wire to the
chassis, as explained in
skip this step.
Step 3
Install the slider rails into the rack or cabinet, as follows:
a. Determine which two posts of the rack or cabinet you should use for the slider rails. Of the four vertical posts in the
rack or cabinet, two will be used for the rack-mount brackets, and the other two posts will have the slider rails.
