Follow these precautions when installing your 5400zl switch:
W A R N I N G
Devices installed in a rack or cabinet should be mounted as low
as possible, with the heaviest device at the bottom and progres-
sively lighter devices installed above.
The rack or cabinet should be adequately secured to prevent it
from becoming unstable and/or falling over.
Ensure a cover plate is installed on any empty switch power
supply or module slot. A cover plate is required for safe
operation, and to ensure proper switch cooling. Never have
more than one power supply or module slot uncovered at a
time while the switch is powered on.
To avoid energy and mechanical hazards, never allow any part
of your body, jewelry, tool, or other foreign object to enter any
module or power supply slots.
This unit may have more than one power supply cable. To fully
power down the switch, you must disconnect all power supply
cables from the unit.
