WARNING:
• To reduce the risk of personal injury or damage to equipment: ,
◦ Heed all warnings and cautions throughout the installation instructions.
◦ If you plan to re-ship the switch in its original packaging, remove any transceivers installed
in line modules before preparing the switch for shipment. See also Shipping a rackmounted Aruba 6400 switch chassis.
◦ Observe local occupational health and safety requirements and guidelines for manual
material handling.
◦ The switch is heavy. Avoid personal injury due to the combined weight of the chassis
and installed accessories. If your installation process includes manually lifting or carrying
the switch instead of using a mechanical lift, uninstall the removable accessories from the
switch before moving it. This guide includes information about removing and installing
accessories, as well as the weight of the switch and individual accessories.
• 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 6400 switch is rated to
support the full equipment load you plan to install in the unit.
• Before you power up the switch, ground it reliably. See Grounding the chassis.
• Never have more than one power supply or module slot uncovered at a time while the switch
is powered on. Install a blank slot cover on any empty management module, line module,
power supply, or AC inlet slot opening in the chassis. This provision improves the ow of
cooling air through the chassis. It also helps to contain radio frequency emissions that may
interfere with the operation of other devices.
• Replace only one fan tray at a time. Removing more than one fan tray at a time compromises
system cooling, risks damage to the hardware, and can cause the switch to shut down
abruptly. When replacing (hot-swapping) a fan tray, complete the process within two
minutes. Allowing the switch to operate longer with only one working fan tray installed
reduces the ow of cooling air through the switch chassis and may result in the switch
shutting down. For more information on fan trays, see Installing a fan tray in an empty fan
tray slot.
• To avoid energy and mechanical hazards, never allow any part of your body, jewelry, tool, or
other foreign object to enter any module or power supply slot.
• The switch may use more than one power supply cable. To fully power down the switch, you
must disconnect all power supply cables from the switch.
Chapter 2 Installation precautions and guidelines 9
Page 10
CAUTION:
• Protect the switch and its components from damage caused by ESD (Electrostatic discharge):
◦ See the ESD information under Preventing electrostatic discharge damage.
◦ Always wear an ESD wriststrap 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 6400 Series switch mounted in a rack without rst 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. For more information, see Shipping a rack-mounted
Aruba 6400 switch chassis
• Ensure the source circuits for your 6400 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.
• Only Aruba-approved power cords may be used with Aruba devices. See the power cord
documentation provided in the latest version of the Aruba 6400 Switch Series Installation and
Getting Started Guide. Lost or damaged power cords must be replaced only with Arubaapproved power cords.
• If your installation requires dierent power cords than the ones supplied with the switch or
power supplies, be sure that 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 denes
the regulations for power cords in your country/region. 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 Power cords, power inlet accessories, and power supplies.
• When installing the switch, select AC outlets near the switch for easy access in case the
switch must be powered o.
• Do not install the switch in an environment where the operating ambient temperature
exceeds its specication. (For environmental specications, see Specications.)
• 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 6400 Series switch. Then compare
the total with the rating limit for the circuit. The maximum ampere ratings are printed on the
devices near their AC power connectors.
• Ensure that the air ow through the chassis is not restricted. Leave a front and rear clearance
of at least 30 cm (11.8 inches) for air ow. Air ow direction is front-to-rear. (Fully perforated
rack doors are acceptable within the 30 cm spacing.)
• Install a blank slot cover on any empty management module, line module, power supply, or
AC inlet slot opening in the chassis. This provision improves the ow of cooling air through
the chassis. It also 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 5 seconds before
reinstallation. Otherwise, damage to the switch or its components may occur. The power
supply needs this time to dissipate any retained power.

Guide
Page 11
• For proper cooling, the 6405 switch requires two fan trays installed and the 6410 switch
requires four fan trays installed. For more information on fan trays, see Fan trays.
• For rack-free mounting requirements and warnings, see Mounting the switch.
• Protect the equipment from AC power uctuations 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.

• Remove all power supplies, line and management modules, fan trays, and all external cables, including
the power cords, before moving the chassis.
• Use a minimum of four people to manually move a chassis weighing more than 100 lbs, and a minimum
of two people to manually move a chassis weighing less than 100 lbs. To determine chassis weight, see
Aruba 6400 product weights.
WARNING: Aruba recommends using a mechanical lift to move the chassis.
• Lift and lower the chassis slowly. Never move it suddenly.
For information and recommended practices for moving the chassis, see Unpacking, lifting, and moving
the chassis.
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 nger or other conductor may damage system boards or other staticsensitive 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 oors or dissipating oor mats.
• Use conductive eld service tools.
• Use a portable eld service kit with a folding static-dissipating work mat.
• Use an ESD wrist strap connected to an ESD connection point on the switch (see the following image).
Wrist straps are exible straps with a minimum of 1 megohm ±10 percent resistance. To provide proper

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
WARNING: Do not stare into any ber port or view directly with non-attenuating optical
instruments when the switch has power. The laser light emitted from the ber port may injure
your eyes.
The Aruba 6400 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 for your switch,
the installation site must meet the requirements in this section.
Temperature
CAUTION: 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.
To ensure correct switch operation, make sure the room temperature meets the following requirements.
NOTE: Above 1524m (5000ft), reduce maximum operating temperature by 1°C (1.8°F) per 305m
(1000ft) altitude gain.

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system,
adversely
• 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 lter
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 indoors only.
aect the switch in the following ways:
Grounding
CAUTION: 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. The grounding lug is
located on the rear of the switch, at the bottom edge. This gure shows the grounding lug on
the Aruba 6405 switch. On the Aruba 6410 is located in a similar position.

Power cords, power inlet accessories, and power supplies
Aruba includes the power cord approved for use with your Aruba switch and power supply. Dierent
countries/regions may require dierent power cords. For a list of the power cords approved for use with
your Aruba 6400 switch, see the section that lists power cords under Power cord information.
CAUTION: Only Aruba-approved power cords are supported for use with Aruba devices. Lost or
damaged power cords must be replaced only with Aruba-approved power cords. If your
installation requires a dierent power cord than the one supplied with the switch and/or power
supply, be sure that the cord is adequately sized for the current requirements of the switch. In
addition, be sure to use a power cord displaying the mark of the safety agency that denes the
regulations for power cords in your country or region. The mark is your assurance that the
power cord can be used safely with the switch and power supply.
WARNING: Do not use a damaged or non-recommended power cord with your switch. Using
such power cords voids the switch and power supply warranty. It can also cause serious
electrical problems, including injury or death to personnel, and damage to the switch and other
property. If you cannot verify that you have a power cord approved for use with your switch
model, contact your authorized Aruba dealer or sales representative for assistance.
WARNING: Remove the power cord from the switch and power supply before mounting or
dismounting the switch.

Adding or replacing switch modules with controlled shutdown or hot swap methods
Aruba recommends using the CLI to shut down modules before removing them from the switch. This
provides a controlled shutdown process that minimizes trac loss and loss of function. However it also can
cause a longer delay in getting the replacement module operational. Hot swapping switch modules is also
supported, and enables faster module changeover, though it can also result in trac loss and some system
interruption.
Using controlled shut down to add or replace line modules.
If an empty line module slot is in the default conguration state, a module boots up when installed in the
slot. If there is a conguration mismatch between an installed module and the slot in which it is installed,
the module does not boot up. Use the procedures in this section to bring up a line module in cases where
the slot conguration is a mismatch for the line module.
Adding a line module to an empty, uncongured slot
Prerequisites
• Have an ESD wrist strap ready to use.
• Have available the line module you plan to install in the empty, uncongured slot. When installing a line
module in an uncongured slot, the module will be brought up as Admin-state up.
• Know the conguration you want on the selected slot.
Procedure
1. Put on a snugly tting ESD wrist strap and attach it to the ESD connector on the front of the switch. (See
Protect the switch and components from damage caused by ESD (Electrostatic discharge).)
2. Remove the blank slot cover from the chosen slot and store it for future use.
3. Install the module. As noted above, installing a line module in an uncongured slot brings the module up
as Admin-state up.
Replacing a line module with another of the same type
Prerequisites
Have an ESD wrist strap ready to use.
Have available the replacement line module you plan to install.
Procedure
1. Put on a snugly tting ESD wrist strap and attach it to the ESD connector on the front of the switch. (See .)
2. Use this command to deactivate the slot:
switch(config)# module <SLOT-ID> admin-state down
NOTE: The existing slot conguration remains.
Chapter 9 Adding or replacing switch components 81

3. Remove the module from the slot and place it in an anti-static bag.
4. Install the new module.
5. Use this command to re-activate the slot.
switch(config)# module <SLOT-ID> admin-state up
The module then comes up using the existing slot conguration.
6. Use this command to verify that the module successfully booted and is operational:
switch(config)# show module <SLOT-ID>
For example, to verify a module in slot 1/7, you would use this command and see output similar to the
following:
switch(config)# show module 1/7
Line module 1/7 is up:

Replacing a fan tray
Fan trays are installed in the slots on the rear of the chassis.
CAUTION: Replace only one fan tray at a time. Removing more than one fan tray at a time
compromises system cooling, risks damage to the hardware, and can cause the switch to shut
down abruptly.
CAUTION: For proper cooling and ventilation, a powered-up 6400 Series chassis must have all
fan trays installed and all four fans in each fan tray running.
• Do not remove a fan tray from a powered up switch without having a replacement fan tray
available.
• When replacing a fan tray in an operating switch, install the replacement fan tray within two
minutes of removing the original fan tray.
• Ensure that all fans in the replacement fan tray are operating after installation.
• If replacing more than one fan tray, ensure each fan tray is correctly installed and operational
before removing the next fan tray.

Basic troubleshooting tips
The following situations cause most problems. Check for these items rst when starting your
troubleshooting:
• Faulty or loose cables. Look for loose or faulty connections. If they appear to be OK, make sure that the
connections are snug. If that does not correct the problem, try a dierent cable.
• Non standard cables. Non standard and mis-wired cables may cause network collisions and other
network problems, and can seriously impair network performance. Use a new, correctly wired cable. For
pinouts and correctly wired cable, compare your cable to the cable information in the latest version of
the ArubaOS-Switch and ArubaOS Transceiver Guide at https://asp.arubanetworks.com/downloads. A
category 5 cable tester is a recommended tool for every 1000Base-T network installation.
• Improper Network Topologies. It is important to ensure that you have a valid network topology.
Common topology faults include excessive cable length and excessive repeater delays between end
nodes. If you have network problems after recent changes to the network, change back to the previous
topology. If you no longer experience the problems, the new topology is likely at fault.
In addition, make sure that your network topology contains no data path loops. Between any two end
nodes, there must be only one active cabling path at any time. Data path loops cause broadcast storms
that severely impact your network performance.
Building redundant paths between important nodes in your network provides some fault tolerance.
Before opening redundant paths, enable Spanning Tree Protocol support on the switch. Spanning tree
ensures that only one of the redundant paths is active at any time, thus avoiding data path loops.
Spanning Tree can be enabled through the switch console or the web browser interface.
The 6400 switches also support Trunking (link aggregation), which allows using multiple network cables
for a single network connection without causing a data path loop. For more information, go to https://
asp.arubanetworks.com/downloads and see these publications:
◦ Spanning Tree: Layer 2 Bridging Guide
◦ Trunking: Link Aggregation Guide
• Using event and debug logs, show tech, and run-time diagnostics. These built-in features can help to
isolate the sources of problems. For more information, see the Diagnostics and Supportability Guide at
https://asp.arubanetworks.com/downloads.
Functions of the management module reset button
CAUTION: Use a hard reset on a management module only if other methods to recover from a
loss of control have failed. Using a hard reset can result in corrupting the le system on the
management module SSD (solid state drive). In this case, reformatting the management module
SSD is required to recover.

System power consumption
To determine the maximum power consumption of an Aruba 6400 switch, determine the quantity of each
component installed in the table titled "Component power usage". Multiply the quantity installed by the
"Power per component" to determine the total power consumption of each component type. Sum the total
of all component types to determine the total maximum power consumption for the system.

Power is reduced to 2950 at 200VAC nominal. This primarily applies to Japan, as they are the only country with a 200VAC
high line. However, the power drop can also occur in other electrical environments where the high line power drops to
200VAC for any reason.
NOTE: Power consumption numbers reect worst case conditions under maximum trac
loading. In practice actual power consumption is typically less than these limits.
These power consumption limits are used by the management software to determine how much power to
allocate for each module. If there is not enough available power for all line cards installed, the management
software may not power all cards to stay below the available power.
Power available for PoE: Excess power available from the power supplies beyond the total system and line
module allocation is available for PoE powered devices sourced by the line modules.
Redundancy: If power supply or AC grid redundancy is required, add additional power supplies to the
system.
Example using an Aruba 6405:
• Installed components:

◦ Two 1800W PSUs @ 200-240 VAC (high line)
◦ Two management modules
◦ All fan trays installed
◦ Four R0X38A Aruba 6400 48p 1G CLS 4 Mod
◦ One R0X42A Aruba 6400 12p 40G/100G QSFP28 Mod
• System power required: 645W + (4 x 113W) + (1 x 338W) = 1435W
• Available power: 2 x 1800W = 3564W (see table)
• Excess power available for PoE: 3564W -- 1435W = 2129W
• If power supply redundancy is required:
◦ Available power comes from one less PSU, which equals 1800W.
◦ Excess power available for PoE is: 1800W -- 1435W = 365W.
