8Aruba 8400 Switch Series Installation and Getting Started Guide

Using a mechanical lift to raise, lower, and move the Aruba 8400 chassis is the recommended best practice. If a
mechanical lift is used, ensure that the configured weight does not exceed the maximum load capacity of the lift.
Install any uninstalled components after mounting the switch.
Chapter 2
Installation precautions and guidelines
Chapter 2 Installation precautions and guidelines 9

• To reduce the risk of personal injury or damage to equipment, heed all warnings and cautions
throughout the installation instructions.
• The switch is heavy. To reduce the risk of personal injury or damage to the equipment, observe
local occupational health and safety requirements and guidelines for manual material handling.
• Avoid personal injury due to the combined weight of the chassis and installed components.
Before moving the chassis, uninstall the following components if your installation process includes
manually lifting or carrying the chassis instead of using a mechanical lift. Uninstalling the listed
components reduces the combined weight of the chassis and components to 60 kg (132 lbs) or
less. For the weight of each individual component, see Product weights on page 117.
◦ To minimize weight, remove these components from the chassis:
– All power supplies
– All line modules
– Two fan trays
◦ Attach the four removable handles provided with the chassis.
◦ Use a team of four people to raise, lower, and carry the chassis.
See Move the chassis to the mounting location on page 42.
• Mount devices installed in a rack or cabinet as low as possible. Install the heaviest devices at the
bottom and progressively lighter devices above.
• To prevent the rack or cabinet from becoming unstable and/or falling over, ensure that it is
adequately secured.
• Ensure that the rack or cabinet unit in which you plan to mount the 8400 switch is rated to support
the full equipment load you plan to install in the unit.
• Before you use the switch, ground it reliably. See Grounding the chassis on page 61.
• Mounting a chassis with the front even (flush) with the front of a two-post rack is not supported
and can result in a hazardous weight distribution in the rack. See Preparing the chassis for two-
post rack mounting on page 49.
10 Aruba 8400 Switch Series Installation and Getting Started Guide

• Protect the switch and its components from damage caused by ESD (Electrostatic discharge):
◦ See Preventing electrostatic discharge damage on page 14.
◦ Always wear an ESD wrist strap when handling the switch or its components. Ensure the strap
is reliably grounded when installing or removing switch components.
◦ Hold management modules, line modules, and fabric modules by their edges. Do not touch
any electronic components or printed circuitry.
◦ Store uninstalled modules in antistatic bags.
• Do not ship the Aruba 8400 Series switch mounted in a rack without first checking for rack
requirements and restrictions. Otherwise, damage to the switch or components may occur.
Damage resulting from using unsupported methods or equipment to ship a rack-mounted chassis
may void the switch warranty. See Shipping a rack-mounted Aruba 8400 switch chassis on
page 47.
• Ensure the power source circuits for your 8400 Series switch are properly grounded. Connect the
switch to the power sources by using the power cords supplied with the switch or power supply
units.
• If your installation requires different power cords than the ones supplied with the switch or power
supplies, be sure the cords are adequately sized for the current requirements. In addition, be sure
to use power cords displaying the mark of the safety agency that defines the regulations for
power cords in your country. The mark is your assurance that the power cord can be used safely
with the switch and power supply. For more on power cords, see the latest version of the Aruba
8400 Switch Series Initial Hardware Setup and Safety/Regulatory Guide available at http://
www.hpe.com/support/manuals.
• When installing the switch, select AC outlets near the switch for easy access in case the switch
must be powered off.
• Do not install the switch in an environment where the operating ambient temperature exceeds its
specification. (For environmental specifications, see the latest version of the Aruba 8400 Switch
Series Initial Hardware Setup and Safety/Regulatory Guide at http://www.hpe.com/support/
networking.)
• Ensure that the switch does not overload the power circuits, wiring, and over-current protection.
To determine the possibility of overloading the supply circuits, add the ampere ratings of all
devices installed on the same circuit as the 8400 Series switch. Then compare the total with the
rating limit for the circuit. The maximum ampere ratings are usually printed on the devices near
their AC power connectors.
• Ensure that the air flow through the chassis is not restricted. Leave a front and rear clearance of
at least 30 cm (11.8 inches) for air flow. Air flow direction is front-to-rear.
Chapter 2 Installation precautions and guidelines 11

30 cm (11.8 in)
30 cm (11.8 in)
• Install a blank slot cover on any empty management module and line module slot. This helps to
contain radio frequency emissions that may interfere with the operation of other devices.
• If a power supply must be removed, and then reinstalled, wait at least 20 seconds before
reinstallation. Otherwise, damage to the switch or its components may occur. The power supply
needs this time to dissipate any retained power.
• The switch requires three fully populated fan trays. Each fan tray holds six replaceable fan
modules. For more information on fan trays and fan module requirements, see Installing a fan
tray in any empty fan tray slot on page 71.
• Install a slot cover on any module or power supply slot that is not in use.
• For rack-free mounting requirements and warnings, see (Optional) Installing the chassis in a
non-rack mounted position on page 45.
• Protect the equipment from AC power fluctuations and temporary interruptions with a regulating
facility Uninterruptible Power Supply (UPS) device. This device protects the hardware from
damage caused by power surges and voltage spikes, which keeps the switch in operation during
a power failure.
• The Aruba 8400 Switch Series chassis and accessories do not include any user-serviceable
parts. For service, please contact your authorized Aruba representative.

Safety recommendations
Before installing an Aruba 8400 Switch, and to avoid possible bodily injury and equipment damage, carefully read
these publications before installation:
•Safety, Compliance, and Warranty Information (shipped with the switch)
• The Aruba 8400 Switch Series Initial Hardware Setup and Safety/Regulatory Guide (shipped with the switch)
• All safety recommendations in this chapter
• The chapter titled Installation precautions and guidelines on page 9
The recommendations in the listed publications do not cover every possible hazardous condition.
General safety recommendations
• Keep the chassis clean and dust-free.
• Do not place the switch on a moist area, and avoid liquid flowing into the switch.
• Make sure the floor is dry and flat, and anti-slip measures are in place.
• Keep the chassis and installation tools away from walk areas.
• Do not wear loose clothing, jewelry (for example, a necklace), or any other items that could get caught in the
chassis when you install and maintain the switch.
Electricity safety
• Clear the work area of possible electricity hazards, such as ungrounded power extension cables, missing
safety grounds, and wet floors.
• Locate the emergency power-off switch in the room before installation so you can quickly shut power off if an
electrical accident occurs.
• Remove all external cables, including power cords, before moving the chassis.
• Do not work alone when the switch has power.
Handling safety
Do not use the handle of a fan tray or a power supply unit, or the chassis air vents to lift or move the
switch. Any attempt to move the switch with these parts may cause equipment damage and bodily
injury.
Chapter 3
Site preparation
Chapter 3 Site preparation 13

When you move the switch, follow these guidelines:
• Remove all power supplies, line modules, two fan trays, and all external cables, including the power cords,
before moving the chassis.
• Use a minimum of four people to manually move the chassis. Aruba recommends moving the chassis using a
mechanical lift, if available.
• Lift and lower the chassis slowly. Never move it suddenly.
• Use the lifting handles on both sides of the chassis. Attach the handles by following the directions indicated by
the arrows in the image below.

For information and recommended practices for moving the chassis, see Unpacking, lifting, and moving the
chassis on page 37.
Preventing electrostatic discharge damage
Be aware of the precautions you must follow when setting up the switch or handling components. A discharge of
static electricity from a finger or other conductor may damage system boards or other static-sensitive devices.
This type of damage may reduce the life expectancy of the switch or component.
To prevent electrostatic damage:
• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Always use a properly grounded ESD wrist strap when touching static-sensitive components or assemblies.
Use one or more of the following methods when handling or installing electrostatic-sensitive parts:
• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when
standing on conductive floors or dissipating floor mats.
• Use conductive field service tools.
14 Aruba 8400 Switch Series Installation and Getting Started Guide

• Use an ESD wrist strap connected to an ESD connection point on the switch (refer to the image below). Wrist
straps are flexible straps with a minimum of 1 megohm ±10 percent resistance. To provide proper ground,
wear the strap snug against the skin.

• Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an Aruba authorized reseller install
the part.
For more information on static electricity or assistance with product installation, contact an Aruba authorized
reseller.
Laser safety
Do not stare into any fiber port or view directly with non-attenuating optical instruments when the
switch has power. The laser light emitted from the fiber port may injure your eyes.
The Aruba 8400 switches are Class 1 laser products.
Examining the installation site
The switch must be used indoors. To help ensure correct operation and a long service life of your switch, the
installation site must meet the requirements in this section.
Weight support
Make sure the floor can support the total weight of the rack, chassis, modules, power supplies, and all other
components. Take into consideration system expansions (for example, adding more modules) when you plan the
loading capacities.
For component weights, see Product weights on page 117.
Temperature
If condensation appears on the chassis when you move it to a high-temperature environment, dry the
chassis before powering it on to avoid short circuits.
Chapter 3 Site preparation 15

To ensure correct operation of the switch, make sure the room temperature meets the requirements below.
Above 1524m (5000ft), reduce maximum operating temperature by 1°C (1.8°F) per 305m (1000ft)
altitude gain.
Table 1: Temperature requirements
Temperature Range
Operating temperature 0°C to 40°C (32°F to 104°F)
Storage temperature –40°C to +70°C (–40°F to +158°F)
For more environmental information, see the latest version of the Aruba 8400 Switch Series Initial Hardware
Setup and Safety/Regulatory Guide at http://www.hpe.com/support/manuals.
Humidity
Maintain the humidity in your equipment room in the acceptable range, as described below.
• Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical property change of
materials, and metal corrosion.
• Lasting low relative humidity can cause washer contraction and ESD, and cause problems including loose
mounting screws and circuit failure.
Table 2: Humidity requirements
Humidity Range
Operating humidity 5% to 95%, noncondensing
Storage humidity 5% to 95%, noncondensing
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of metal
components and contact points. In the worst case, electrostatic adsorption can cause communication failure.
Table 3: Dust concentration limit in the equipment room
Substance Concentration limit (particles/m3)
Dust particles ≤ 3 x 104 (No visible dust on desk in three days)
Dust particle diameter ≥ 5 μm
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and premature
aging of components, as shown below.

EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system,
adversely affect the switch in the following ways:
• A conduction pattern of capacitance coupling.
• Inductance coupling.
• Electromagnetic wave radiation.
• Common impedance (including the grounding system) coupling.
To prevent EMI, use the following guidelines:
• If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to filter
interference from the power grid.
• Keep the switch far away from radio transmitting stations, radar stations, and high-frequency devices.
• Use electromagnetic shielding (for example, shielded interface cables) when necessary.
• To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes, route
interface cables only indoors.
Grounding
Reliably ground the switch to protect it from hazards such as lightning shocks, interferences, and
ESD discharges. The switch is grounded through the safety wire in the power cords. Aruba
recommends an independent grounding connection for the chassis if there is any doubt about the
reliability of the grounding through the power mains. See the location of the grounding lug, shown
below.
Chapter 3 Site preparation 17

1 Grounding lug
Make sure the resistance between the chassis and the ground is less than 1 ohm.
Power
Perform the following tasks to meet the power requirements:
Procedure
1. Calculate the system power consumption. The system power consumption varies by module type and density.
(See System power consumption on page 119.)
2. Identify the number of power supplies. Include sufficient power to meet power consumption and sufficient
redundancy to ensure system uptime in the event of a PSU failure.
3. Verify that the power system at the installation site meets the requirements of the power supplies, including the
input method and rated input voltage. (For power supply unit information, see the latest version of the Aruba
8400 Switch Series Power Supply Installation and Safety/Regulatory Guide at http://www.hpe.com/support/
manuals.)
Cooling
Plan the installation site for adequate ventilation:
• Leave a minimum of 30 cm (11.81 in) of clearance at the front and rear of the switch.
Air flow into and out of the switch is indicated by the arrows in the image below.
• The rack for the switch has a good cooling system.
• The installation site has a good cooling system.
• Verify that the airflow design of the chassis meets the airflow design of the installation site.
