which it is connected. If all the power supplies on a single switch are connected to the same power
source, the entire switch is vulnerable to a power failure.
WARNING!
Wiring a DC power cord to your facility DC source voltage must be performed by a qualified,
licensed electrician.
Extreme Networks AC power supplies do not have switches for turning the unit on and off. Remove the wall plug
from the electrical outlet to disconnect the power from an Extreme Networks AC power supply. Make sure that this
connection is easily accessible.
Do not connect an EPS-600LS power supply to an electrical outlet when the power supply is not installed in the
EPS-C chassis; doing so would expose a hazardous energy and poses a potential shock and fire hazard.
Do not connect Summit X460, X480, or X650 AC power supply to an electrical outlet when the power supply is not
installed in the switch; doing so would expose a hazardous energy and poses a potential shock and fire hazard.
Do not put your hand into an open power supply bay when a power supply is not present. Empty power supply
bays require a cover plate at all times.

Maintenance Safety

When you perform maintenance procedures on Extreme Networks equipment, follow these
recommendations:
Use only original accessories or components approved for use with this system. Failure to follow
G
these instructions may damage the equipment or violate required safety and EMC regulations.
The chassis cover should only be removed by Extreme Networks personnel. This system contains no
G
customer serviceable components. Repairs to the system must be performed by an Extreme
Networks factory service technician.
In systems that have power-on buttons, the power on button may not turn off all system power. To
G
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
G
maintenance procedure.
Replace a power cord immediately if it shows any signs of damage.
G
When you work with optical devices, power supplies, or other modular accessories, put on an ESD-
G
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. Leave the ESD-preventive
wrist strap permanently attached to the equipment rack so that it is always available when you need
to handle ESD-sensitive components.
Install all cables in a manner that avoids strain. Use tie wraps or other strain relief devices.
