Rack-mounting Kit Dimensions and Instructions
(Optional: RK-3U-02)
Please refer to the RK-3U-02 Series QIG.
Matters That Require Attention
1. Elevated Operating Temperature: If installed in a closed or
multi-unit rack assembly, the operating ambient temperature of
the rack environment may be greater than room temperature.
Therefore, consideration should be given to installing the
equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
NOTE
In order to ensure reliable operations, please make sure the
operating temp
erature of the environment does not exceed the
spec. When mounting a rack
-mounted switch with other
operating units in a cabinet without forced ventilation, it is
recommended that 1U of space is reserved between each rack
-
mounted switch and/or device.
2. Required Air Flow: Installation of the equipment in a rack should
be such that the amount of air flow required for safe operation of
the equipment is not compromised.
3. Mechanical Loading: Mounting of the equipment in the rack
should be such that a hazardous condition is not achieved due to
uneven mechanical loading.
4. Circuit Overloading: Consideration should be given to the
connection of the equipment to the supply circuit and the effect
that overloading of the circuits might have on overcurrent
protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this
concern.
5. Reliable Grounding: Reliable grounding of rack-mounted
equipment should be maintained. Particular attention should be
given to supply connections other than direct connections to the
branch circuit (e.g. use of power strips).
ATTENTION
Safety First
!
Be sure to disconnect the power cord before installing and/or
wiring your Ethernet Switch. Calculate the maximum
possible
current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for
each wire size. If the current goes above the maximum ratings,
the wiring could overheat,
which can cause serious damage to
your equipment.
WARNING
When end users are
using Optical SFP Communications
modules, these must be limited to Laser Class 1.
