Preparing for Installation
Warning
Do not stack the chassis on any other equipment. If the chassis falls, it can
cause severe bodily injury and equipment damage.
Warning
To comply with safety regulations, mount switches on a wall with the front
panel facing up.
Warning
If a redundant power system (RPS) is not connected to the switch, install an RPS
connector cover on the back of the switch.
Warning
The plug-socket combination must be accessible at all times because it serves
as the main disconnecting device.
Warning
To prevent the switch from overheating, do not operate it in an area that
exceeds the maximum recommended ambient temperature of 113
°
F (45
°
C). To
prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around
the ventilation openings.
Warning
When installing the unit, always make the ground connection first and
disconnect it last.
Warning
This equipment is intended to be grounded. Ensure that the host is connected to
earth ground during normal use.
Warning
Before working on equipment that is connected to power lines, remove jewelry
(including rings, necklaces, and watches). Metal objects will heat up when
connected to power and ground and can cause serious burns or weld the metal
object to the terminals.
