•
Clearance to front panels is such that the LEDs can be easily read.
•
Power cord reaches from the power outlet to the connector on the switch.
•
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting
fixtures.
•
Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or
multirack assembly, the temperature around it might be greater than normal room temperature.
The Catalyst 3560CX-12PD-S and C3560CX-8XPD-S switches have a maximum
operating temperature of 40°C. All the other switches have a maximum operating
temperature of 45°C. However, for WS-C3560CX-8XPD-S, the maximum operating
temperature will be 35°C when installed inverted and under fully loaded conditions
(maximum PoE and 10G SFP+ transceivers installed).
Note
•
Humidity around the switch does not exceed 95 percent.
•
Altitude at the installation site is not greater than 10,000 feet.
•
Airflow around the switch and through the vents must be unrestricted. To avoid any flow blockage, we
strongly recommend these guidelines:
◦
Allow at least 3 in. (7.6 cm) of clearance from the left and right sides, and the front and rear of the
switch.
◦
If you are installing the switch upright, allow at least 1.75 in. (4 cm) of clearance from the top
cover.
◦
If you are installing the switch inverted, under a table, allow at least 3 in. (7.6 cm) of clearance
from the top cover.
◦
If you are installing the switch in a rack, allow at least 1RU of empty rack space above each switch.
For Catalyst 3560CX-12PD-S and C3560CX-8XPD-S switches operating at the maximum
specified temperature and fully loaded conditions (with transceivers installed and
maximum PoE), when installed inverted, there should be unrestricted airflow all around
the switch (and not just limited to the minimum 3 in. requirement). When installed
upright, at least 3 in. of clearance from the top cover is required. When installed in a
rack, at least 2RU of empty rack space above each switch is required.
Note
•
When placing the switch on a flat horizontal surface, we strongly recommend that you attach the rubber
feet to the switch.
•
For 10/100/1000 fixed ports, cable lengths from the switch to connected devices can be up to 328 feet
(100 meters).
•
For cable requirements for SFP module connections, see the
“
SFP Module Cables, on page 60
”
section.
Each port must match the wave-length specifications on the other end of the cable, and the cable must
not exceed the minimum cable length.
