Overview of the Cisco Nexus 3548-10G, 3548-10GX, and 3524
Switches
The Cisco Nexus 3548P-10G (N3K-C3548P-10G), 3548P-10GX (N3K-C3548P-10GX), and 3548P-XL
(N3K-C3548P-XL) are 1 rack unit (RU) switches with 48 fixed 1- and 10-Gigabit Ethernet small form-factor
pluggable (SFP+) ports, 1 fixed 10/100/1000 management port (the Cisco Nexus 3548P-10G also has 1
disabled management port, but there are no plans to enable this port at any future date), 1 console port, and
1 (Cisco Nexus 3548P-10G) or 2 (Cisco Nexus 3548P-10GX) USB ports. This 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 Cisco Nexus 3524P (N3K-C3524P-10G) is a Cisco Nexus 3548 switch but with only 24 ports enabled
and can be upgraded to use all 48 ports. It is the lowest entry point for main-stream top-of-rack (TOR) data
center deployments which offers wire-rate Layer 2 and Layer 3 switching with a comprehensive feature set,
including Algo Boost technology, and ultra-low latency.
The following figure shows the fan-side chassis features that you use when installing the chassis or replacing
its modules.

•Temperature Requirement, on page 3
•Humidity Requirement, on page 3
•Altitude Requirements, on page 3
•Dust and Contaminants, on page 3
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
This switch is rated to operate at 8- to 80-percent relative humidity with 10-percent gradation per hour. It can
be stored in an environment that has 5- to 95-percent 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 10,000 feet (0 to 3050 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.

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.
• 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 35 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.

Installing the Chassis
Installation Options with Rack-Mount Kits, Racks, and Cabinets

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.
Warning
• 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.
Avoid UPS types that use ferroresonant technology. These UPS types can become
unstable with systems such as the Cisco Nexus 3000 Series 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
Statement 1005—Circuit Breaker
This product relies on the building's installation for short-circuit (overcurrent)

• Port-side exhaust airflow direction indicated with blue coloring
Installing a 1 (RU) Chassis in a Four-Post Rack
This section describes the rack installation for the Cisco Nexus 3000 series switch into a four-post rack.
Installing the Switch Using the NXK-ACC-KIT-1RU Rack-Mount Kit
To install the switch, you must attach front and rear mounting brackets to the switch, install slider rails on the
rear of the rack, slide the switch onto the slider rails, and secure the switch to the front of the rack. Typically,
the front of the rack is the side easiest to access for maintenance.
You must supply the eight 10-32 or 12-24 screws required to mount the slider rails and switch to the rack.
Note
Before you begin
• You have inspected the switch shipment to ensure that you have everything ordered.
• Make sure that the switch rack-mount kit includes the following parts:
Cisco Nexus 3500 Hardware Installation Guide

Installing the Chassis
Installing a 1 (RU) Chassis in a Four-Post Rack

• Front rack-mount brackets (2)
• Rear rack-mount brackets (2)
• Slider rails (2)
• M4 x 0.7 x 8-mm Phillips countersink screws (12)
• The rack is installed and secured to its location.
Step 1 Install two front rack-mount brackets and the two rear rack-mount brackets to the switch as follows:
a) Determine which end of the chassis is to be located in the cold aisle as follows:
• If the switch has port-side intake modules (fan modules with burgundy coloring), position the switch so that its
ports will be in the cold aisle.
• If the switch has port-side exhaust modules (fan modules with blue coloring), position the switch so that its fan
and power supply modules will be in the cold aisle.
b) Position the front rack-mount bracket and the rear rack-mount bracket so that its screw holes are aligned to the screw
holes on the side of the chassis.
You can align the holes in the rack-mount bracket to the holes on the side of the chassis (see the two ways
to mount these brackets on a typical chassis, in following figure). The holes that you use depend on the
requirements of your rack and the amount of clearance required for interface cables (3 inches [7.6 mm]
minimum) and module handles (1 inch [2.5 mm] minimum).
Note
c) Secure the front-mount bracket and the back-mount bracket to the chassis using four M4 screws and tighten each
screw to 12 in-lb (1.36 N·m) of torque.

d) Repeat Step 1 for the other front rack-mount bracket and the other back-mount bracket on the other side of the switch
and be sure to position that bracket the same distance from the front of the switch.
Depending on the chassis depth, the back rack-mount bracket may not fit. In that case the back rack-mount
bracket is not needed.
Note
Step 2 If you are not installing the chassis into a grounded rack, you must attach a customer-supplied grounding wire to the
chassis as explained in the Grounding the Chassis, on page 20 section. If you are installing the chassis into a grounded
rack, you can skip this step.
Step 3 Install the slider rails on the rack or cabinet as follows:
a) Determine which two posts of the rack or cabinet you should use for the slider rails. Of the four vertical posts in the
rack or cabinet, two will be used for the front mount brackets attached to the easiest accessed end of the chassis, and
the other two posts will have the slider rails.
b) Position a slider rail at the desired level on the back side of the rack and use 12-24 screws or 10-32 screws, depending
on the rack thread type, to attach the rails to the rack (see the following figure). Tighten 12-24 screws to 30 in-lb
(3.39 N·m) of torque and tighten 10-32 screws to 20 in-lb (2.26 N·m) of torque.
c) Repeat Step 3 to attach the other slider rail to the other side of the rack.
To make sure that the slider rails are at the same level, you should use a level tool, tape measure, or carefully count
the screw holes in the vertical mounting rails.
Step 4 Insert the switch into the rack and attach it as follows:
a) Holding the switch with both hands, position the two rear rack-mount brackets on the switch between the rack or
cabinet posts that do not have slider rails attached to them (see the following figure).
Cisco Nexus 3500 Hardware Installation Guide
11
Installing the Chassis
Installing the Switch Using the NXK-ACC-KIT-1RU Rack-Mount Kit

b) Align the two rear rack-mount guides on either side of the switch with the slider rails installed in the rack. Slide the
rack-mount guides onto the slider rails, and then gently slide the switch all the way into the rack until the front
rack-mount brackets come in contact with two rack or cabinet posts.
c) Holding the chassis level, insert screws (12-24 or 10-32, depending on the rack type) in each of the two front rack-mount
brackets (using a total of six screws) and into the cage nuts or threaded holes in the vertical rack-mounting rails (see
the following figure).
d) Tighten the 10-32 screws to 20 in-lb (2.26 N·m) or tighten the 12-24 screws to 30 in-lb (3.39 N·m).
Step 5 If you attached a grounding wire to the chassis grounding pad, connect the other end of the wire to the facility ground.
