To mount your 210 or 220 series switch in a two-post rack, follow these steps.
For 12-port switches, see Mounting 12-Port Switches. 12-port switches are smaller than 24- and 48-port switches and are mounted differently.
Note
Take care to load the rack so that it is not top-heavy. Start installing equipment at the bottom and work up.Set the flange even with the front panel of the switch and use four chassis screws (provided) to secure the bracket to the switch. See Attaching a Rack-mounting Bracket.
Secure the mounting bracket flanges to the rack, using screws that are appropriate for the rack. (Rack-mounting screws are not provided.) See Sliding the Switch into the Rack.
After the switch is securely in place, install optional components using the instructions in Installing Optional Components.
Connect power to the switch. See Connecting Power to the Switch.
