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: Use the screws specified in the procedure. Using longer screws can damage the device.
CAUTION: To avoid damaging blade and chassis, do not push the blade into a slot or pull the blade
from a slot using the ejector handles.
CAUTION: Do not attempt to lift or support the chassis by the logo bezel attached over the port-
side air vents.
CAUTION: Remove the logo bezel protective cover on the port side of chassis before applying
power. This cover is attached over the air vents. If not removed, the chassis can overheat and will
eventually shut down.
Electrical Cautions
CAUTION: Use a separate branch circuit for each power cord, which provides redundancy in case
one of the circuits fails.
CAUTION: For the NEBS-compliant installation of a Brocade device , use a ground wire of at least
2 AWG. The ground wire should have an agency-approved crimped connector (provided with the
device) attached to one end, with the other end attached to building ground. The connector must
be crimped with the proper tool, allowing it to be connected to both ground screws on the
enclosure. Before crimping the ground wire into the provided ground lug, ensure that the bare
copper wire has been cleaned and antioxidant is applied to the bare wire. In addition, anti-rotation
devices or lock washers must be used with all screw connections for the grounding wire.
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.
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: All devices with AC power sources are intended for installation in restricted access
areas only. A restricted access area is a location where access can be gained only by trained
service personnel through the use of a special tool, lock and key, or other means of security.
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: The maximum input voltage for connection to the HVAC/HVDC power supply should not
exceed 305 VAC and 400 VDC .
Cautions Related to Equipment Weight
CAUTION: Do not use the port cover tabs to lift the module. They are not designed to support the
weight of the module, which can fall and be damaged.
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.
Danger notices
A Danger statement indicates conditions or situations that can be potentially lethal or extremely
hazardous to you. Safety labels are also attached directly to products to warn of these conditions or
situations.
