Preparing for Installation
Warning For connections outside the building where the equipment is installed, the following ports must be
connected through an approved network termination unit with integral circuit protection.
10/100/1000 Ethernet Statement 1044
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into
beams or view directly with optical instruments. Statement 1051
Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074
Installation Guidelines
Before you install the switch module in the server chassis, read these guidelines:
• Review and become familiar with the safety and handling guidelines specified in the server chassis
Product Information Guide.
• Review the “Warnings” section on page 2-1 and the Regulatory Compliance and Safety Information
for the Cisco Catalyst Blade Switch 3030 that accompanies this guide.
• To help ensure proper cooling and system reliability, keep these points in mind:
– Each server chassis I/O module bay must contain either a module or an end-cap (blank plug).
– When you remove a hot-swap module, you must replace it with an identical module or an
end-cap (blank plug) within 1 minute of removal.
Caution To prevent electrostatic-discharge (ESD) damage when installing switch modules, follow your normal
board and component handling procedures.
Note When you install a switch module, you do not need to power down the server modules or the chassis.
Note The initial configuration assumes that the switch module was never configured, that it is in the same state
as when it was received, and that it is not configured with a default username and password.
Be sure to observe these requirements:
• For copper Ethernet ports, including 10/100/1000 ports and 1000BASE-T SFP module ports, cable
lengths from the switch to connected devices can be up to 328 feet (100 meters).
• See the documentation for the SFP module for more information about cable specifications for 1for
the SFP module connections. Each port must match the wave-length specifications on the other end
of the cable, and the cable must not exceed the stipulated cable length for reliable communications.
Note When using shorter lengths of single-mode fiber-optic cable, you might need to insert an inline
optical attenuator in the link to avoid overloading the receiver.
