3.3 Installation Planning
Since the S7500 series are a kind of complex equipment, it is necessary to make a
good plan and arrangement concerning installation position, networking mode, power
supply and cabling before installation.
3.3.1 Installation Space Requirement
For better heat dissipation and equipment maintenance, it is recommended that the
front and back of the switch should be at least 1 m (39.4 in.) away from walls or other
devices, and that the left and right side should be at least 0.8 m (31.5 in.) away from
walls. If the switch is to be installed in a cabinet, the headroom in the equipment room
should be 3 m (9.84 ft.) at least.
3.3.2 Cabinet-Mounting Requirements
Before mounting the switch in a cabinet, make sure the cabinet meets the following
requirements:
z
Mount the switch in an open cabinet if possible. However, if you mount a switch in
a closed cabinet, make sure that the cabinet is equipped with a good heat
dissipation system.
z
Make sure that the cabinet is steady enough to support the switch and
accessories.
z
Make sure that the cabinet fits the switch size, and that there is clearance around
the left and right panels of the switch for heat dissipation.
