Preparing for Installation
Height Requirements
The rack must have sufficient clearance in terms of height, to insert the chassis. Chassis height is also measured
in rack units (RU or just U) where 1 RU or 1 U equals 1.75 inches (44.45 mm). A typical server rack is 42
RU or 42 U in height.
The chassis heights are as follows:
• The Catalyst 9404R Switch chassis height—10.5 inches (26.67 cms)—6 RU.
• The Catalyst 9407R Switch chassis height—17.41 inches (44.22 cms)—10 RU.
• The Catalyst 9410R Switch chassis height—22.61 inches (57.43 cms)—13 RU.
Other General Guidelines
Caution
If the equipment rack is on wheels, ensure that the brakes are engaged and that the rack is stabilized.
Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to
ensure that the system remains stable. The following guidelines are provided to ensure your safety:
• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
unit in the rack. Statement 1006
Warning
Take care when connecting units to the supply circuit so that wiring is not overloaded. Statement 1018
Warning
To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended
ambient temperature of: 104o F (40o C) Statement 1047
Note
To maintain proper air circulation through the switch chassis, we recommend that you maintain a minimum
space of 6 inches (15 cm) between a wall and the chassis and power supply unit air intakes or a wall and the
chassis and power supply unit hot air exhausts. In situations where the switch chassis are installed in adjacent
racks, you should allow a minimum space of 12 inches (30.5 cm) between the air intake of one chassis and
the hot air exhaust of another chassis. Failure to maintain adequate spacing between chassis may cause the
switch chassis that is drawing in the hot exhaust air to overheat and fail.
