Aruba 6400 Series Installation And Getting Started Manual page 8

Mount devices installed in a rack or cabinet as low as possible. Install the heaviest devices at the bottom
n
and progressively lighter devices above.
To prevent the rack or cabinet from becoming unstable and/or falling over, ensure that it is adequately
n
secured.
Ensure that the rack or cabinet unit in which you plan to mount the 6400 switch is rated to support the full
n
equipment load you plan to install in the unit.
Before you power up the switch, ground it reliably. See
n
Never have more than one power supply or module slot uncovered at a time while the switch is powered
n
on. Install a blank slot cover on any empty management module, line module, power supply, or AC inlet slot
opening in the chassis. This ensures the flow 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
n
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 (6405) or three working fan trays (6410) installed reduces the flow of
cooling air through the switch chassis and will result in the switch shutting down. For more information on
fan trays, see Installing a Fan Tray in an Empty Fan Tray
To avoid electrical and mechanical hazards, never allow any part of your body, jewelry, tool, or other foreign
n
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
n
disconnect all power supply cables from the switch.
Protect the switch and its components from damage caused by ESD (Electrostatic discharge):
n
See the ESD information under
l
Always wear an ESD wriststrap when handling the switch or its components. Ensure the strap is reliably
l
grounded when installing or removing switch components.
Hold management modules and line modules by their edges. Do not touch any electronic components or
l
printed circuitry.
Store uninstalled modules in antistatic bags.
l
Do not ship the Aruba 6400 Series switch mounted in a rack without first checking for rack requirements
n
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
Ensure the source circuits for your 6400 Series switch are properly grounded. Connect the switch to the
n
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
n
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 Aruba-approved power cords.
If your installation requires different power cords than the ones supplied with the switch or power supplies,
n
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 defines 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
page 32.
When installing the switch, select AC outlets near the switch for easy access in case the switch must be
n
powered off.
