Statement 1030—Equipment Installation
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Preparing to Install the Chassis
Before you can install the switch, you must verify the following:
• The installation site meets the following requirements as stated in Chapter 2:
Cisco Nexus 3600 Hardware Installation Guide
8
◦ Environmental requirements for temperature, humidity, altitude, and air particulates.
◦ Cabinet or rack is installed and meets the requirements for the switch.
Jumper power cords are available for use in a cabinet.
Note
◦ The rack is positioned so that you can install the switch with its cold air intakes positioned in a
cold aisle.
If the fan and power supply modules are burgundy colored, you must install the chassis with its
port side in a cold aisle. If the modules are blue colored, you must be able install the chassis with
the fan modules in a cold aisle.
◦ Earth ground connection is close to the switch. You must be able to easily connect the switch
directly to an earth ground or indirectly through a grounded rack.
◦ Site power meets the switch requirements. If you are using n+n redundancy, you must have two
power sources within reach of the switch when it is installed in the cabinet or rack.
If available, you can use an uninterruptible power supply (UPS) to protect against power failures.
Caution Avoid UPS types that use ferroresonant technology. These UPS types can become
unstable with systems such as the Cisco Nexus 3000 Series switches. These switches
can have substantial current draw fluctuations because of fluctuating data traffic patterns.
Ensure that circuits are sized according to local and national codes. For North America, the power
supply requires a 15-A or 20-A circuit.
To prevent loss of input power, ensure the total maximum loads on the circuits supplying

power to the switch are within the current ratings for the wiring and breakers.
