Chapter 2 Installing the Cisco UCS 6100 Series Fabric Interconnect
Preparing for Installation
Installation Guidelines
When installing the Cisco UCS 6100 Series Fabric Interconnect, follow these guidelines:
• Prepare the site as described in the Cisco UCS Site Preparation Guide.
• Plan your site configuration and prepare the site before installing the chassis. Appendix C, “Site
Planning and Maintenance Records,” lists the recommended site planning tasks.
• Record the information listed in Appendix C, “Site Planning and Maintenance Records,” 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
(
Appendix A, “Technical Specifications,” lists airflow requirements).
• Ensure that the air conditioning meets the heat dissipation requirements listed in Appendix A,
“Technical Specifications.”
Note Jumper power cords are available for use in a cabinet. See the “Jumper Power Cord” section on
page B-8.
• Ensure that the chassis is adequately grounded. If the chassis is not mounted in a grounded rack, we
recommend 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 Appendix A, “Technical
Specifications.” 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 UCS 6100 Series 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.
Caution To prevent loss of input power, ensure 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 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)
