When using this product, observe all danger, caution, and attention notices in this manual. The safety notices are accompanied by symbols that represent the severity of the safety condition.
Refer to Cautions and Danger Notices at the end of this guide for translations of safety notices for this product.
Warning
The procedures in this manual are for qualified service personnel.Warning
Before beginning the installation, see the precautions in “Power precautions.”Warning
Be careful not to accidently insert your fingers into the fan tray while removing it from the chassis. The fan may still be spinning at a high speed.
Caution
Changes or modifications made to this device that are not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.Caution
Disassembling any part of the power supply and fan assembly voids the warranty and regulatory certifications. There are no user-serviceable parts inside the power supply and fan assembly.Caution
Make sure the airflow around the front, and back of the device is not restricted.Caution
Ensure that the airflow direction of the power supply unit matches that of the installed fan tray. The power supplies and fan trays are clearly labeled with either a green arrow with an "E", or an orange arrow with an "I."Caution
To protect the serial port from damage, keep the cover on the port when not in use.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 filler panel in place. If you run the chassis with an uncovered slot, the system will overheat.Caution
Use the screws specified 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).Warning
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.Warning
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.Warning
If the installation requires a different power cord than the one supplied with the device, make sure you use a power cord 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 device.Warning
Disconnect the power cord from all power sources to completely remove power from the device.Warning
This device might have more than one power cord. To reduce the risk of electric shock, disconnect all power cords before servicing.Warning
To avoid high voltage shock, do not open the device while the power is on.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.Warning
Use safe lifting practices when moving the product.Warning
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.Warning
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.Warning
All fiber-optic interfaces use Class 1 lasers.Warning
Laser Radiation. Do Not View Directly with Optical Instruments. Class 1M Laser Products.Warning
Use only optical transceivers that are qualified by Extreme Networks, Inc. and comply with the FDA Class 1 radiation performance requirements defined 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.
