Overview of the Cisco Nexus 3408-S Switch

The Cisco Nexus 3408-S (N3K-C3408-S) is a 4 rack unit (RU) 8-slot modular chassis switch, which is configurable with up to 128 100-Gigabit QSFP28 ports or 32 400-Gigabit ports. This switch offers 2 management ports, 1 console port, and 1 USB port. This switch supports port-side intake airflow. The switch requires one AC, DC, or HVAC/HVDC power supply for operation, 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

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.

CHAPTER 2

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.

Warning

Statement 1071—Warning Definition

IMPORTANT SAFETY INSTRUCTIONS

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device.

SAVE THESE INSTRUCTIONS

Statement 1017—Restricted Area

This unit is intended for installation in restricted access areas. A restricted access area can be accessed by skilled, instructed or qualified personnel.

Statement 1030—Equipment Installation

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Cisco Nexus 3400-S Hardware Installation Guide

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.

Note

Jumper power cords are available for use in a cabinet.

• 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.

Installing the Chassis

• 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.

Warning

High leakage current. Earth connection essential before connecting to power supply.

• 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.

Caution

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.

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 switch are within the current ratings for the wiring and breakers.

• 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:

Cisco Nexus 3400-S Hardware Installation Guide

Installing the Chassis

Unpacking and Inspecting the Chassis

• 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)

• Antistatic surface large enough to place the switch

• Grounding cable (6 AWG recommended), sized according to local and national installation requirements; the required length depends on the proximity of the switch to proper grounding facilities

• Crimping tool large enough to accommodate the girth of the grounding lug

• Wire stripping tool

Unpacking and Inspecting the Chassis

Caution

Step 1 Compare the shipment to the equipment list provided by your customer service representative and verify that you have

received all items.

Step 2 Check for damage and report any discrepancies or damage to your customer service representative. Have the following

information ready:

When handling switch components, such as fan or power supply modules, wear a grounded ESD strap and handle the modules by their carrier edges only. To ground the ESD strap, make sure that it is attached to an earth ground, a grounded chassis, or a grounded rack.

Tip

Keep the shipping container in case the chassis requires shipping in the future.

Note

The switch is thoroughly inspected before shipment. If any damage occurred during transportation or any items are missing, contact your customer service representative immediately.

To inspect the switch, follow these steps:

• Invoice number of shipper (see the packing slip)

• Model and serial number of the damaged unit

• Description of damage

• Effect of damage on the installation

• Photos of the damaged shipping containers and damaged product

Step 3 For duel direction airflow switches, check to be sure that all of the fan and power supply modules have the same airflow

direction.

• Port-side intake airflow direction indicated with burgundy coloring

• Port-side exhaust airflow direction indicated with blue coloring

Installing a 4 (RU) Chassis in a Four-Post Rack

This section describes the rack installation for the Cisco Nexus 3408-S platform switch into a four-post rack.

Before moving or lifting the chassis, follow these guidelines:

• Ensure that all cables are disconnected from the switch.

• Ensure that there is adequate space around the switch for servicing and airflow.

• Never attempt to lift an object that might be too heavy for you to lift by yourself.

• Ensure that you have solid footing and that the weight of the switch is evenly distributed between your feet.

• Lift the switch slowly, keeping your back straight. Lift with your legs, not with your back. Bend at the knees, not at the waist.

Step 1 Attach two front-mount brackets to the sides of the chassis as follows:

a) Align the two holes in one side of a front-mount bracket to the holes on the left or right side of the chassis as shown

in the following figure.

b) Use M4 x 6 mm screws to attach the bracket to the chassis and tighten each screw to 12 in-lb (1.36 N·m) of torque. c) Repeat Steps 1a and 1b to attach the other front-mount bracket to the other side of the chassis.

Step 2 Align the bottom-support rails so that they form a shelf for the chassis.

Note

The bottom-support rails are identical and interchangeable. Each can be used for either the right, or the left side of the rack.

a) Rotate one of the rails as shown in the following figure.
