2.7 Installation location
The Switch can be installed either on a table or a 19-inch cabinet rack.
(1) Table
Install the Switch on a level, stable and flat table. In addition, satisfy the requirements
described in
Table 2-10 Conditions for installing the device on a table.
Table 2-10 Conditions for installing the device on a table
Item Conditions
Space for air intake and
exhaust
Ensure more than 50 mm of free space around all air vents of the Switch.
(For details, see
2.9 Cooling conditions.)
Space for cables Ensure 100 mm of free space in front and rear of the Switch to deal with
the cables.
Noise of the switch
For details about noise, see 2.10 Noise of the Switch.
If placing the Switch on a desk, lay it on its side on a workbench capable of withstanding
the weight of the Switch. If, for example, you place the Switch on a shaky table or a tilted
surface, the Switch might fall and possibly injure someone.
Because the AX2230S-24T, AX1250S-24T2C, and AX1240S-24T2C are fanless
models, heat also dissipates from the top panels of these switches. To ensure
adequate heat dissipation, do not stack another device on top of or below the
Switch.
When mounting these Switches in a rack, keep a space of 1U or more between
them.
(2) 19-inch cabinet rack
When mounting the device on a rack, satisfy the rack requirements described in Table 2-11
Rack requirements. In addition, provide the items listed in
Table 2-12 Required items for
mounting the device on a rack.
