CAUTION
Never leave tools inside the chassis.
CAUTION
If you do not install a module or a power supply in a slot, you must keep the slot ller panel in place. If you run the chassis
with an uncovered slot, the system will overheat.
CAUTION
Use the screws specied in the procedure. Using longer screws can damage the
device.
CAUTION
Do not install the device in an environment where the operating ambient temperature might exceed 50°C (122°F).
DANGER
Batteries used for RTC/NVRAM backup are not located in operator-access areas. There is a risk of explosion if a battery
is replace by an incorrect type. Dispose of used components with batteries according to local ordinance and regulations.
ESD precautions
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
CAUTION
Static electricity can damage the chassis and other electronic devices. To avoid damage, keep static-sensitive devices in
their static-protective packages until you are ready to install them.
CAUTION
Before plugging a cable into any port, be sure to discharge the voltage stored on the cable by touching the electrical
contacts to ground surface.
Power precautions
DANGER
If the installation requires a dierent power cord than the one supplied with the device, make sure you use a power cord
displaying the mark of the safety agency that denes the regulations for power cords in your country. The mark is your
assurance that the power cord can be used safely with the device.
DANGER
Disconnect the power cord from all power sources to completely remove power from the device.
DANGER
This device might have more than one power cord. To reduce the risk of electric shock, disconnect all power cords before
servicing.
DANGER
To avoid high voltage shock, do not open the device while the power is on.
Safety precautions

CAUTION
Use a separate branch circuit for each power cord, which provides redundancy in case one of the circuits fails.
CAUTION
Ensure that the device does not overload the power circuits, wiring, and over-current protection. To determine the
possibility of overloading the supply circuits, add the ampere (amp) ratings of all devices installed on the same circuit as the
device. Compare this total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the
devices near the input power connectors.
Lifting precautions
DANGER
Use safe lifting practices when moving the product.
DANGER
Mount the devices you install in a rack as low as possible. Place the heaviest device at the bottom and progressively place
lighter devices above.
DANGER
Make sure the rack housing the device is adequately secured to prevent it from becoming unstable or falling over.
CAUTION
To prevent damage to the chassis and components, never attempt to lift the chassis using the fan or power supply handles.
These handles were not designed to support the weight of the chassis.
Laser precautions
DANGER
All ber-optic interfaces use Class 1 lasers.
DANGER
Laser Radiation. Do Not View Directly with Optical Instruments. Class 1M Laser Products.
DANGER
Use only optical transceivers that are qualied by Extreme Networks, Inc. and comply with the FDA Class 1 radiation
performance requirements dened in 21 CFR Subchapter I, and with IEC 60825 and EN60825. Optical products that do
not comply with these standards might emit light that is hazardous to the eyes.
Facility requirements
To install and operate the device successfully, ensure compliance with the following facility requirements.
Electrical considerations
For successful installation and operation of the device, ensure that the following electrical requirements are met:
• The primary outlet is correctly wired, protected by a circuit breaker, and grounded in accordance with local electrical codes.
Facility requirements
ExtremeSwitching SLX 9540 Hardware Installation Guide
9036360-00 Rev AB 19

• The supply circuit, line fusing, and wire size are adequate, as specied by the electrical rating on the device nameplate.
• The power supply standards are met.
Environmental considerations
For successful installation and operation of the device, ensure that the following environmental requirements are met:
• Because the SLX 9540 Switch can be ordered with fans that move air either front to back or back to front, be sure to orient
your switch with the airow pattern of any other devices in the rack. All equipment in the rack should force air in the same
direction to avoid intake of exhaust air.
• Some combinations of intake and exhaust airow may not be compatible with your environment. Consult your fan assembly
and power supply FRU kits to determine the correct conguration.
• The ambient air temperature does not exceed 50°C (122°F) while the switch is operating with front-to-back airow, or 45°C
(113°F) while the switch is operating with back-to-front airow.
Location considerations
Before installing the device, plan its location and orientation relative to other devices and equipment. Devices can be mounted in a
standard 19-inch equipment rack or on a at horizontal surface.
The site should meet the following requirements:
• Maintain the operating environment as specied in “Environmental considerations” ExtremeSwitching SLX 9540 Technical
Specications on page 91.
• For installation on a at horizontal surface, the SLX 9540 Switch should be installed with its top and bottom covers parallel to
the oor. The SLX 9540 Switch should not be installed upside down.
• Allow a minimum of 3 in. of space between the front and the back of the device and walls or other obstructions for proper
airow.
• Allow at least 3 in. of space at the front and back of the device for the twisted-pair, ber-optic, and power cabling.
• Allow access space for installing, cabling, and maintaining the devices.
• Ensure the status LEDs are clearly visible.
• Allow for twisted-pair cables to be routed away from power lines, uorescent lighting xtures, and other sources of electrical
interference, such as radios and transmitters.
• Allow for the unit to be connected to a separate grounded power outlet that provides 100 to 240 VAC, 50 to 60 Hz, is within 2
m (6.6 ft) of each device, and is powered from an independent circuit breaker. As with any equipment, a lter or surge
suppressor is recommended.
Cable management recommendations
Cables can be organized and managed in a variety of ways; for example, use cable channels on the sides of the rack or patch panels to
reduce the potential for tangling the cables. The following list provides some recommendations for cable management:
NOTE
Before plugging a cable to any port, be sure to discharge any static charge stored on the cable by touching the electrical
contacts to ground surface.
• You should not use tie wraps with ber-optic cables because they are easily overtightened and can damage the optical bers.
Velcro-like wraps are recommended.
