General Dangers
Danger: The procedures in this manual are for qualified service personnel.
Danger: Make sure that the power source
circuits are properly grounded, then use the power cord supplied with the device
to
connect it to the power source.
Danger: This equipment is suitable for mounting on concrete or other noncombustible surfaces
only.
Danger: The equipment ports are
intrabuilding type and must not be directly connected to metallic outside plant
(OSP) cable conductors.
Electrical Dangers
Danger: Before
beginning the installation, see the precautions in “Power Precautions.”
Danger: 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.
Danger: For
safety reasons, the ESD wrist strap should contain a series 1 megohm resistor.
Danger: To reduce the risk of electric shock,
disconnect all power cords before servicing.
Danger: Disconnect the power cord from all power sources to completely remove power from
the device.
Danger: 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.
Danger: Batteries used for RTC/NVRAM backup are not located in operator-access areas. There
is a risk of explosion if a battery is replaced by an incorrect type. Dispose
of
used components with batteries according to local ordinance and regulations.
Danger: To avoid high voltage shock, do not open the device while the power is on.
Danger: 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.
Danger: High Touch Current. Earth connection essential before connecting supply.
Danger: Make sure to choose the appropriate circuit device depending on the number of AC
power supplies installed in the chassis. The minimum current draw for the system is
one AC power supply.
Danger: Make sure that the power source circuits are properly grounded.
Danger: Power-down your device before you install or replace a power supply or module for
safety purposes and to avoid instability due to a delay in power cycling.
Danger: Connect the power cord only to a grounded outlet.
Dangers Related to Equipment Weight
Danger: Make sure the rack housing the device is adequately secured to prevent it from becoming
unstable or falling over.
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: Use safe lifting practices when moving the product.
Danger: When mounting the device under a fixed surface, under a desk, or under a shelf,
mount the device with the bottom panel down and in a place where there is not
much
foot traffic. The fixed surface must be strong enough to withstand the weight
of the
device such that the device or the surface does not fall down.
Laser Dangers
Danger: All fiber-optic interfaces use Class 1 lasers.
Danger: Class 1M laser radiation. Do not view directly with optical instruments.
Danger: Use only
optical transceivers that are qualified by RUCKUS 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.
