Temperature Requirements

The switch requires a operating temperature of 32 to 104° F (1 to 40° C). If the switch is not operating, the temperature must be between –40 to 158° F (–40 to 70° C).

Humidity Requirements

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 operate at 8 to 80 percent relative humidity, with a humidity gradation of 10 percent per hour. For nonoperating conditions, the switch can withstand from 5 to 95 percent relative humidity. Buildings in which the climate is controlled by air-conditioning in the warmer months and by heat during the colder months usually maintain an acceptable level of humidity for the switch equipment. However, if the switch is located in an unusually humid location, you should use a dehumidifier to maintain the humidity within an acceptable range.

Cisco Nexus 9508 Switch Site Preparation and Hardware Installation Guide

OL-30837-01 5

Altitude Requirements

If you operate a switch at a high altitude (low pressure), the efficiency of forced and convection cooling is reduced and can result in electrical problems that are related to arcing and corona effects. This condition can also cause sealed components with internal pressure, such as electrolytic capacitors, to fail or to perform at a reduced efficiency. This switch is rated to operate at altitudes from –500 to 13,123 feet (–152 to 4,000 meters). You can store the switch at altitudes of –1,000 to 30,000 feet (–305 to 9,144 meters).

Dust and Particulate Requirements

Exhaust fans cool power supplies and system fan trays cool switches by drawing in air and exhausting air out through various openings in the chassis. However, fans also ingest dust and other particles, causing contaminant buildup in the switch and increased internal chassis temperature. A clean operating environment can greatly reduce the negative effects of dust and other particles, which act as insulators and interfere with the mechanical components in the switch.

In addition to regular cleaning, follow these precautions to avoid contamination of your switch:

Preparing the Site

Do not permit smoking near the switch.

•

Do not permit food or drink near the switch.

•

Minimizing Electromagnetic and Radio Frequency Interference

Electromagnetic interference (EMI) and radio frequency interference (RFI) from the switch can adversely affect other devices such as radio and television (TV) receivers operating near the switch. Radio frequencies that emanate from the switch can also interfere with cordless and low-power telephones. Conversely, RFI from high-power telephones can cause spurious characters to appear on the switch monitor.

RFI is defined as any EMI with a frequency above 10 kHz. This type of interference can travel from the switch to other devices through the power cable and power source or through the air like transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI that can be emitted by computing equipment. Each switch meets these FCC regulations.

To reduce the possibility of EMI and RFI, follow these guidelines:

Cover all open expansion slots with a blank filler plate.

•

Always use shielded cables with metal connector shells for attaching peripherals to the switch.

•

When wires are run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires with the following implications:

Bad wiring can result in radio interference emanating from the plant wiring.

•

Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers

•

and receivers in the chassis and even create an electrical hazard by conducting power surges through lines into equipment.

Preparing the Site

Grounding Requirements

Note

Caution

To predict and prevent strong EMI, you might need to consult experts in radio frequency interference (RFI).

The wiring is unlikely to emit radio interference if you use twisted-pair cable with a good distribution of grounding conductors. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic switches. You might want to consult experts in electrical surge suppression and shielding if you had similar problems in the past.

Grounding Requirements

The switch is sensitive to variations in voltage supplied by the power sources. Overvoltage, undervoltage, and transients (or spikes) can erase data from the memory or cause components to fail. To protect against these types of problems, ensure that there is an earth-ground connection for the switch. You can connect the grounding pad on the switch either directly to the earth-ground connection or to a fully bonded and grounded rack.

You must provide the grounding cable to make this connection, but you can connect the grounding wire to the switch using a grounding lug that ships with the switch. Size the grounding wire to meet local and national installation requirements. Depending on the power supply and system, a 12 AWG to 6 AWG copper conductor is required for U.S. installations (for those installations, we recommend that you use commercially available 6 AWG wire). The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

Note

You automatically ground the AC power supplies when you connect them to a power source. You must also connect the chassis to the facility earth ground.

Planning for Power Requirements

To plan for the power requirements of a switch, you must determine each of the following:

Power requirements for all of the switch components

•

Minimum number of power supplies required to power the components installed in the switch

•

Power mode to use and the number of additional power supplies required for that mode

•

You must also ensure that the circuit used for the switch is dedicated to the switch to minimize the possibility of circuit failure.

Cisco Nexus 9508 Switch Site Preparation and Hardware Installation Guide

OL-30837-01 7

Planning for Power Requirements

When you know the amount of power that is required for operations (available power) and redundancy (reserve power), you can plan for the required number of input power receptacles within reach of the switch location.

Preparing the Site

Step 1

Determine the power requirement for the switch by summing the maximum wattage for each installed module (see the following table).

Table 1: Power Requirements for the Cisco Nexus 9508 Switch Modules

Step 2

Step 3

176 W250 W3Fan Trays (N9K-C9508-FAN)

To determine the maximum amount of power that can be consumed by this switch when fully loaded with components, add the maximum power consumed by two supervisors (2 x 80 W = 160 W), two system controllers (2 x 25 W = 50 W), eight 48-port 1- and 10-Gigabit BASE-T I/O modules (8 x 550 W = 4400 W), six fabric modules (6 x 250 W = 1500 W), and three fan trays (3 x 250 W = 750 W). The total is 6860 W.

Determine the number of power supplies needed for the available power requirement by dividing the power requirement amount (see Step 1) by the output wattage of the power supplies installed in the switch. For 3-kW power supplies, round up a fractional result to the nearest ones digit to determine the number of power supplies needed.

For example, if you are installing a switch with 3-kW power supplies and have a maximum consumption of 6960 W, you need three power supplies (6960 W / 3000 W = 2.32 [rounded up to 3 power supplies]) to operate the switch and all of its modules.

Select one of the following power modes to determine the number of additional power supplies required for reserve power:

Cisco Nexus 9508 Switch Site Preparation and Hardware Installation Guide

8 OL-30837-01

Preparing the Site

Rack and Cabinet Requirements

• Combined power—Do not add any power supplies to the number of power supplies calculated for the available

power in Step 2. This power mode does not provide power redundancy, so no extra power supplies are needed.

• Power supply redundancy (n+1 redundancy)—Add one power supply (reserve power supply) that can output as

much power as the most powerful power supply used for active power. This form of power redundancy provides a reserve power supply that can replace any active power supply that goes offline.

• Input source redundancy (grid or n+n redundancy)—Add enough power supplies (reserve power supplies) to at

least equal the total output of the active power supplies (the number of power supplies calculated in Step 2). Typically, you double the number of power supplies. You must plan for a second power source for the reserve power supplies. For example, if you calculate that you need two 3-kW power supplies for 6 kW of available power, you need another two 3-kW power supplies for 6 kW of reserve power (for a total of four 3-kW power supplies used for available and reserve power).

Step 4

Step 5

Be sure that the power source circuits are dedicated to the switch and not to other electrical equipment. For combined power mode (no power redundancy) or power supply (n+1) redundancy, you need only one dedicated circuit. For input-source (grid or n+n) redundancy, you must have two dedicated power circuits, with each circuit powering half of the 3-kW power supplies. The requirements for each circuit are listed in the following table.

Table 2: Circuit Requirements for 3-kW Power Supplies

Requirement for Each CircuitNumber of CircuitsPower Supply

16 A at 210 to 240 VAC13-kW AC power supply (N9K-PAC-3000W-B)

Plan the placement of the input power receptacles within reach of the power cables used for each power supply (see the following table for the maximum distances). Typically, power receptacles are placed on the rack with the switch.

Maximum Distance Between Receptacle and Power SupplyPower Supply

12 feet (3.5 m)All AC power supplies

Rack and Cabinet Requirements

You can install the following types of racks or cabinets for your switch:

Standard perforated cabinets

•

Solid-walled cabinets with a roof fan tray (bottom to top cooling)

•

Standard open four-post Telco racks

•

To correctly install the switch in a cabinet that is located in a hot-aisle/cold-aisle environment, you should fit the cabinet with baffles to prevent exhaust air from recirculating into the chassis air intake.

Cisco Nexus 9508 Switch Site Preparation and Hardware Installation Guide

OL-30837-01 9

Rack and Cabinet Requirements

Work with your cabinet vendors to determine which of their cabinets meet the following requirements or see the Cisco Technical Assistance Center (TAC) for recommendations:

Use a standard 19-inch (48.3 cm), four-post Electronic Industries Alliance (EIA) cabinet or rack with

•

mounting rails that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992 standard.

The height of the rack or cabinet must accommodate the 13-RU (22.7 inches or 57.8 cm) height of the

•

switch and its bottom support bracket.

The depth of a four-post rack must be 24 to 32 inches (61.0 to 81.3 cm) between the front and rear

•

mounting brackets.

Required clearances between the chassis and the edges of its rack or the interior of its cabinet are as

•

follows:

Preparing the Site

4.5 inches (11.4 cm) between the front of the chassis and the front of the rack or interior of the

◦

cabinet (required for cabling).

3.0 inches (7.6 cm) between the rear of the chassis and the interior of the cabinet (required for

◦

airflow in the cabinet if used).

Warning

No clearance is required between the chassis and the sides of the rack or cabinet (no side airflow).

◦

Additionally, you must consider the following site requirements for the rack:

Power receptacles must be located within reach of the power cords used with the switch.

•

Power cords for 3-kW AC power supplies are 8 to 12 feet (2.5 to 4.3 m) long.

◦

Clearance is required for cables that connect to as many as 384 ports (in addition to the cabling required

•

for other devices in the same rack). These cables must not block access to any removable chassis modules or block airflow into or out of the chassis. Route the cables through the cable management frames on the left and right sides of the chassis.

Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over.

Step 3

OL-30837-01 13

Bolt the rack to the subfloor before moving the chassis onto it.

Warning

Statement 1048

If the rack has bonded construction, connect it to the earth ground. This action enables you to easily ground the switch and its components and to ground your electrostatic discharge (ESD) wrist strap to prevent discharge damage when you handle ungrounded components during installation.

If you need access to the source power at the rack, include AC power receptacles with the amperage required by the switch that you are installing. For amperage and other circuit requirements, see Rack and Cabinet Requirements, on

page 9.

Statement 1018

Note

Take care when connecting units to the supply circuit so that wiring is not overloaded.Warning

If you are using the combined power mode or power-supply redundancy, you need only one power source. If you are using input-source redundancy, you need two power sources.

the unit in the rack.

Statement 1006

Before You Begin

Before you can install the bottom support rails for the chassis, you must do the following:

Verify that a four-post rack or cabinet is installed and secured to the concrete subfloor (see Installing a

•

Rack or Cabinet).

If any other devices are stored in rack or cabinet, verify that they are located below where you plan to

•

install the switch. Also, verify that lighter devices in the same rack are located above where you plan to install this switch.

Verify that the bottom-support rails kit is included in the switch accessory kit (see Unpacking and

•

Inspecting a New Switch).

Step 1

Verify that you have the following tools and equipment:

•

Mechanical lift capable of lifting the full weight of the chassis and its installed modules

◦

Note

The chassis can weigh up to 395 pounds (179 kg) when it is fully loaded. You can lighten the chassis for easier moving by removing its power supplies, fan trays, and fabric modules. To determine the full weight of the chassis and the appropriate weight rating for the mechanical lift, see Weights and Quantities for the Chassis, Modules, Fan Trays,

and Power Supplies, on page 84.

Note

You must use a mechanical lift to elevate a switch that weighs over 120 pounds (55 kg).Caution

Installation of the equipment must comply with local and national electrical codes.Warning

If you need to make the chassis as light as possible for moving, remove the following modules and place them where their connectors will not be damaged:

• Power supplies—For each power supply, press and hold the eject lever, and use the handle on the front of the power

supply to pull the power supply out of the chassis.

• Fan trays—Unscrew the four captive screws, and use the two handles on the fan tray to pull the fan tray out of the

chassis.

Step 2

Step 3

Step 4

• Fabric modules—For each fabric module, keep your face at least 12 inches (30 cm) away from the modules, press

both eject buttons on the front, rotate both levers away from the front of the module, use the levers to pull the module out of the chassis.

Load the chassis onto a mechanical lift as follows:

a) Position the mechanical lift next to the shipping pallet that holds the chassis. b) Elevate the lift platform to the level of the bottom of the chassis (or no more than 1/4 inch [0.635 cm] below the

bottom of the chassis).

c) Use at least two persons to slide the chassis fully onto the lift so that the side of the chassis touches or is close to the

vertical rails on the lift. Make sure that the front and rear of the chassis are unobstructed so you can easily push the chassis into the rack.

Warning

To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit.

Note

To lift the chassis, use a mechanical lift. Do not use the handles on the side of the chassis (the handles are not rated for lifting over 200 pounds [91 kg]). Use the side handles for only repositioning the chassis after it is already on the mechanical lift or in the rack or cabinet.

Use the mechanical lift to move and align the rear of the chassis to the front of the four-post rack or cabinet. Make sure that the bottom of the chassis is elevated to the height of the bottom-support rails or no more than 1/4 inch (0.6 cm) above the bracket.

Push the chassis halfway onto the rack or cabinet. Use at least two persons to push the chassis onto the bottom-support rails and one person to guide the chassis down the center of the rails. Push the lower half of the front side of the chassis so that the back side enters the rack first, and push

To adjust the placement of the chassis on the bottom-support rails, you can use the chassis handles (see Callout

Tip

1 in the following figure).

Step 5

If the mechanical lift is raised above the height of the bottom-support rails, gently lower it to the level of the rails or no more than 1/4 inch (0.6 cm) below the rails. This action helps to prevent the bottom of the chassis from getting caught on the expansion edges of the bottom-support rails.
