Preparing for Installation
Installation Guidelines
Before installing the switch, verify that these guidelines are met:
•
Clearance to front and rear panels is such that
–
Front-panel indicators can be easily read.
–
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 X2-10GB-CX4 transceiver module minimum bend radius and connector length is met. See
the X2 transceiver module documentation for more information.
•
If you do not have access to the rear panel, you should cable the switches before you rack-mount
them.
•
Tighten the captive screws on power-supply modules and fan modules before moving the switch.
•
When connecting or disconnecting the power cord on a switch that is installed above or below a
1150-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 X2 module connections, see the
“Cable and Adapter Specifications”
. Each port must match the wave-length specifications on the other end of the
cable, and the cable must not exceed the required cable length.
•
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 installed in a closed or
multirack assembly, the temperature around it might be greater than normal room temperature.
•
Cisco Ethernet Switches are equipped with cooling mechanisms, such as fans and blowers. However,
these fans and blowers 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
