Overview of the Cisco Nexus 3636C-R Switch
The Cisco Nexus 3636C-R (N3K-C3636C-R) is a 1 rack unit (RU) switch with 36 100-Gigabit QSFP28 ports,
2 management ports, 1 console port, and 1 USB port. The switch supports both port-side exhaust and port-side
intake airflow schemes. The switch requires one AC or DC power supply for operations, but it can have a
second power supply for redundancy.
The following figure shows the fan-side chassis features that you use when installing the chassis or replacing
its modules.

Preparing the Site
•Temperature Requirement, on page 5
•Humidity Requirement, on page 5
•Altitude Requirements, on page 5
•Dust and Contaminants, on page 5
Temperature Requirement
This switch is rated to operate at 32 to 104°F (0 to 40°C). It can be stored at -40 to 158°F (-40 to 70°C).
Humidity Requirement
High humidity can cause moisture to enter the switch. Moisture can cause corrosion of internal components
and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size.
The switch is rated to withstand from 5- to 95-percent (nonoperating) and 5- to 90-percent (operating) relative
humidity.
Buildings cooled with air conditioning during warm months and warmed during cold months usually maintain
an acceptable level of humidity. However, if the site is unusually humid, use a dehumidifier to maintain the
required humidity level.
Altitude Requirements
High-altitude (low-pressure) conditions outside of 0 to 5,000 feet (0 to 1524 m) can reduce the cooling
efficiency and cause electrical problems.
Dust and Contaminants
To prevent contaminant buildup and increased internal chassis temperatures, make sure that the operating
environment is as clean as possible and free of dust and other contaminants. Do not permit smoking, food, or
drinks near the switch.

• 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.
Warning
Do not stack anything on top of the chassis.
Warning
Installation Options with Rack-Mount Kits, Racks, and Cabinets
The rack-mount kit enables you to install the switch into racks of varying depths. You can position the switch
with easy access to either the port connections or the fan and power supply modules.
You can install the switch using the following 1 (RU) rack-mount options:
• Rack-mount kit (NXK-ACC-KIT-1RU) which you can order from Cisco. This option offers you easy
installation, greater stability, increased weight capacity, added accessibility, and improved removability
with front and rear removal.

Installation Options with Rack-Mount Kits, Racks, and Cabinets

• Rack-mount kit (NCS-1RU-ACC-KIT) which you can order from Cisco.
• Rack-mount kit (N3K-C3064-ACC-KIT) which you can order from Cisco.
You can install the switch in the following types of racks:
• Open EIA rack
• Perforated EIA cabinet
The rack or cabinet that you use must meet the requirements listed the in General Requirements and Guidelines
for Cabinets and Racks, on page 43 section.
You are responsible for verifying that your rack and rack-mount hardware comply with the guidelines that
are described in this doc.
Note
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:
• 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 or red 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.
High leakage current. Earth connection essential before connecting to power
supply.
Caution
• 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.
Cisco Nexus 3600 Hardware Installation Guide

Installing the Chassis
Preparing to Install the Chassis

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
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.
Caution
For AC input application, please refer to the statement below:
Note
For DC input application for the C3636C-R chassis, please refer to the statement
below:
Note
Statement 1076—Clearance Around the Ventilation Openings
To prevent airflow restriction, allow clearance around the ventilation openings
to be at least
Warning
Statement 1005—Circuit Breaker
This product relies on the building's installation for short-circuit (overcurrent)
protection. Ensure that the protective devices is rated not greater than 70A
(C3636C-R) and 40A (C36180YC-R).
Warning
• 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
bracket to the mounting rails)
• 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)
