• Lift the system slowly, keeping your back straight. Lift with your legs, not with your back. Bend at the
knees, not at the waist.
Installation Guidelines
When installing the Cisco UCS Fabric Interconnect, follow these guidelines:
• Prepare the site as described in the Site Preparation Checklist, on page 71.
• Plan your site configuration and prepare the site before installing the chassis. Site Preparation Checklist,
on page 71 lists the recommended site planning tasks.
• Record the information listed in Site Preparation Checklist, on page 71 as you install and configure the
fabric interconnect.
• Ensure that there is adequate space around the chassis to allow for servicing and for adequate airflow.
Site Preparation Checklist, on page 71 lists airflow requirements.
• Ensure that the air conditioning meets the heat dissipation requirements listed in Site Preparation Checklist,
on page 71.
Jumper power cords are available for use in a cabinet. See Cabinet Jumper Power
Cords, on page 69.
Note
• Ensure that the chassis is adequately grounded. If the chassis is not mounted in a grounded rack, Cisco
recommends connecting both the system ground on the chassis and the power supply ground to an earth
ground.
• Ensure that the site power meets the power requirements listed in Power Specifications, on page 56 If
available, you can use an uninterruptible power supply (UPS) to protect against power failures.
Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems
such as the Cisco UCS Fabric Interconnect, which 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 that the total maximum loads on the circuits supplying power to
the fabric interconnect are within the current ratings for the wiring and breakers.
• Use the following screw torques (listed in Newton-metres) when installing the chassis:
• Captive screws: 4 in-lb (0.45 N m)
• M3 screws: 4 in-lb (0.45 N m)
• M4 screws: 12 in-lb (1.36 N m)
• 10-32 screws: 20 in-lb (2.26 N m)
• 12-24 screws: 30 in-lb (3.39 N m)
