Cisco 220 Series Smart Plus Switches Quick Start Guide 5
Mounting the Cisco 220 Switch
There are three ways to physically install the switch:
• Place the switch on a flat surface. To place the switch on a desktop,
install the four rubber feet (included) on the bottom of the switch.
• Mount the switch in a standard rack (1 rack unit high).
• Mount the switch to a wall (non-PoE models only).
Placement Tips
•Ambient Temperature—To prevent the switch from overheating, do not
operate it in an area that exceeds an ambient temperature of 122°F
(50°C).
•Air Flow—Be sure that there is adequate air flow around the switch.
• Mechanical Loading—Be sure that the switch is level and stable to
avoid any hazardous conditions.
• Circuit Overloading—Adding the switch to the power outlet must not
overload that circuit.
Rack Mounting
You can mount the switch in any standard size, 19-inch (about 48 cm) wide
rack. The switch requires 1 rack unit (RU) of space, which is 1.75 inches
(44.45 mm) high.
CAUTION For stability, load the rack from the bottom to the top, with the
heaviest devices on the bottom. A top-heavy rack is likely to
be unstable and might tip over.
To install the switch into a 19-inch standard chassis:
STEP 1 Attach one of the supplied brackets on the side of the switch so that
the four holes align to the screw holes, and use the four supplied M5
(non-PoE models) or M4 (PoE models) screws to secure it.
