Safety and Regulatory Information
Maintenance Safety
When you perform maintenance procedures on Extreme Networks equipment, follow
these recommendations:
•
Use only authorized accessories or components approved for use with this system.
Failure to follow these instructions may damage the equipment or violate required
safety and regulations.
•
This system contains no customer serviceable components. Do not attempt to repair
a chassis, power supply, module, or other component. In the event of failure, return
the defective unit to Extreme Networks for repair or replacement, unless otherwise
instructed by an Extreme Networks representative.
•
To remove power from the system, you must unplug all power cords from wall
outlets. The power cord is the disconnect device to the main power source.
•
Disconnect all power cords before working near power supplies, unless otherwise
instructed by a product-specific maintenance procedure.
•
Replace a power cord immediately if it shows any signs of damage.
•
When you work with optical devices, power supplies, or other modular accessories,
put on an ESD-preventive wrist strap to reduce the risk of electronic damage to the
equipment. Connect the other end of the strap to an appropriate grounding point
on the equipment rack or to an ESD jack on the chassis if one is provided. Leave the
ESD-preventive wrist strap permanently attached to the equipment rack or chassis
so that it is always available when you need to handle components that are sensitive
to ESD.
•
Install all cables in a manner that avoids strain. Use tie wraps or other strain relief
devices.
Fiber Optic Ports and Optical Safety
The following safety warnings apply to all optical devices used in Extreme Networks
equipment that are removable or directly installed in an I/O module or chassis system.
Such devices include but are not limited to gigabit interface converters (GBICs),
small form factor pluggable (SFP) modules (or mini-GBICs), QSFP+ modules, XENPAK
transceivers, and XFP laser optic modules.
Warning
Laser optic modules become very hot after prolonged use. Take care when
removing a laser optic module from the module or option card. If the laser
optic module is too hot to touch, disengage the laser optic module and allow it
to cool before removing it completely.
When working with laser optic modules, always take the precautions listed
below to avoid exposure to hazardous radiation.
•
Never look at the transmit LED/laser through a magnifying device while the transmit
LED is powered on.
•
Never look directly at a fiber port on the switch or at the ends of a fiber cable when
they are powered on.
