Preparing for Installation
Warning
To prevent the system from overheating, do not operate it in an area that exceeds the maximum
recommended ambient temperature of:
113°F (45°C)
Statement 1047
Warning
No user-serviceable parts inside. Do not open.
Statement 1073
Warning
Installation of the equipment must comply with local and national electrical codes.
Statement 1074
Warning
To prevent airflow restriction, allow clearance around the ventilation openings to be at least:
3 in. (7.6 cm)
Statement 1076
Note The grounding architecture of this product is DC-isolated (DC-I).
Installation Guidelines
Before installing the switch, verify that these guidelines are met:
•For the clearance to the front and rear panels, make sure that
–
Front-panel indicators can be easily read.
–
Clearance is at least 4.4 in. (11.1 cm) from switch rear panel.
–
Access to ports is sufficient for unrestricted cabling.
–
AC power cord can reach from the AC power outlet to the connector on the switch rear panel.
–
The SFP or SFP+ module minimum bend radius and connector length is met. See the SFP or
SFP+ module documentation for more information.
•For switches with the optional 1025-W power-supply module (PWR-C2-1025WAC=), first
rack-mount the switch before installing the power-supply module.
•Make sure power-supply modules and fan modules are securely inserted in the chassis before
moving the switch.
•When connecting or disconnecting the power cord on a switch that is installed above or below a
1025-W power supply-equipped switch, you might need to remove the module from the switch to
access the power cord.
•Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent
lighting fixtures. Make sure that the cabling is safely away from other devices that might damage
the cables.
•For copper connections on Ethernet 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 “Cable and Adapter Specifications”
section on pageB-5. Each port must match the wave-length specifications on the other end of the
cable, and the cable must not exceed the maximum cable length.
