Rack-mounting other S12500X-AF switch models
1. Orient the chassis with its rear facing towards the front of the rack.
2. Lift the chassis until the switch bottom is a little higher than the slide rails on the rack.
3. Pace the switch on the slide rails and slide the switch into the rack along the slide rails until the
mounting brackets are flush against the front rack posts, as shown by callout 2 in Figure2-25,
Figure2-26, Figure2-27, Figure2-28, and Figure2-29, for the S12516X-AF, S12512X-AF,
S12508X-AF, S12504X-AF, and S12502X-AF switches, respectively.
After placing the switch on the slide rails, do not leave go of your hands immediately because
this might tip the switch, damaging the switch or even causing bodily injury.
4. Use M6 screws provided with the switch to attach the mounting brackets to the rack posts.
For the S12516X-AF, S12512X-AF, and S12508X-AF switches, the name plate on the upper
right corner of the front panel covers two mounting screw holes in the mounting brackets.
Screws are not needed for these two mounting holes.
If the mounting holes in the mounting brackets cannot align with the cage nuts on the rack,
verify the following items:
The top flange of the slide rail aligns with the middle of the narrower metal area between

holes.
The cage nuts are installed in the correct holes.
