Preparing to Install the Chassis
Caution
Avoid UPS types that use ferroresonant technology. These UPS types can become
unstable with systems such as the Cisco Nexus switches. These switches can have
substantial current draw fluctuations because of fluctuating data traffic patterns.
Caution
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.
Warning
Statement 1076 Clearance Around the Ventilation Openings
To prevent airflow restriction, allow clearance around the ventilation openings
to be at least
• There is adequate clearance around the rack to install the switch and to allow for unimpeded airflow.
• You have the following equipment in addition to the switch and the kits shipped with the switch:
• Eight customer-supplied 12-24 or 10-32 screws (required for attaching slider rails and mounting
• Number 1 and number 2 Phillips screwdrivers with torque capability
• 3/16-inch flat-blade screwdriver
• Tape measure and level
• ESD wrist strap or other grounding device (wrist strap can be found in the accessory kit)
• Antistatic surface large enough to place the switch
• Grounding cable (6 AWG recommended), sized according to local and national installation
• Crimping tool large enough to accommodate the girth of the grounding lug
• Wire stripping tool

If available, you can use an uninterruptible power supply (UPS) to protect against power failures.
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.
