Preparing
Installation Guidelines
Before installing the switch, verify that these guidelines are met:
•
Front-panel indicators can be easily read, and access to ports is sufficient for unrestricted cabling.
•
AC power cord reaches from the power outlet to the rear panel connector.
•
Access to the switch rear panel to connect the RPS 2300 or the RPS 675. If not, cable the switches
before rack-mounting.
•
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent
lighting fixtures. Make sure that the cabling is 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
“Cables and Adapters” section on
page B-3
.
•
Operating environment is within the ranges listed in
Appendix A, “Technical Specifications.”
•
Airflow around the switch and through the vents is unrestricted.
•
Temperature around the unit does not exceed 113°F (45°C). If the switch is in a closed or multirack
assembly, the temperature around it might be greater than normal room temperature.
•
Cooling mechanisms, such as fans and blowers in the switch, can draw dust and other particles
causing contaminant buildup inside the chassis, which can result in system malfunction. You must
install this equipment in an environment as free from dust and foreign conductive material (such as
metal flakes from construction activities) as is possible.
These standards provide guidelines for acceptable working environments and acceptable levels of
suspended particulate matter:
–
Network Equipment Building Systems (NEBS) GR-63-CORE
–
National Electrical Manufacturers Association (NEMA) Type 1
–
International Electrotechnical Commission (IEC) IP-20
