1. Obtain the following tools and equipment:
• Flat blade or Phillips screwdriver (type to match mounting screws)
2. Determine what rack size is being used. When installing in a 19-inch rack use the hardware
provided to attach the chassis to the rack.
Caution:
If chassis is installed in a closed or multi-rack a ssembly, the operating temp erature of the
rack environment may be greater than the ambi ent tempe rature. B e sure to i nstall the chass is in an
environment that is compatible with the maxim um ra ted amb ient t emp eratu re. See Sp ecif icatio ns.
Caution: Installation of the equipment in a rack should be such that air f low to the equipmen t is
not compromised.
3. Locate the equipment rack mounting space that is specified for the chassis.
Note: Ethernet cabling distance to and from the chassis should not exceed 328ft. (100m).
Note: If installing chassis in a Q-Frame (Cross-Connect Solution), make ground
connection to chassis before securing chassis in the rack.
4. Place chassis in the assigned mounting space and align the holes in the mounting brackets
with the holes in the equipment rack. See Figure 1.
5. Secure chassis to equipment rack using the appropriate hardware. Torque these screws to
approximately 27 pound-inches (3.1 Newton meters).
Caution: When mounting equipment in the rack make sure mechanical loading is even to avoid
a hazardous condition, such as loading heavy equipment in the rack unevenly. The rack should
safely support the combined weight of all equipment it supports.
In the Quareo cross-connect solution frame there are eight spaces for mounting network chassis.
Consider them to be numbered one through eight starting at the top, see Figure 2.
When installing Quareo Network Chassis in the odd spaces (1, 3, 5, 7) the first chassis in each
space is secured using the top mounting hole in the chassis and the lowest hole in chassis. When
installing Quareo Network Chassis in the even spaces (2, 4, 6, 8) the first chassis in each space is
secured using the second mounting hole in the ch assis and the lowe st hole in ch assis. See
Figure 3
.
3.3Grounding Chassis
This procedure establishes a ground connection between the chassis and the earth ground
connection. Frame ground terminations (10-32 screws) are provided on the chassis, for a frame
ground connection. This connection must be made in accordance with all local and national
electrical codes.
1. Locate ground location on chassis, see Figure 4. At grounding location remove protective
tape from chassis.
2. Using AWG 14 (1.6mm) solid copper wire, secure two hole ground lug to one end of the
ground wire (installer provided). Secure ground lug to chassis with two 10-32 screws.
Torque ground screws to approximately 15 pound-inches (1.7 Newton meters).
Caution:
should be given to supply connections other than direct connections to the branch circuit (e.g. use
of power strips).
3. To assure proper operation the chassis should be connected to a good earth ground. There
Reliable earthing of rack-mounted equipment should be maintained. Particula r attention
must be no switching or disconnecting devices in the grounding circuit conductor between
the power source and the point of connection to the grounding electrode conductor.
4. Connect the other end of the ground wire to the earth ground conductor. Ensure this
connection is made using methods and hardware that meets all applicable local and
national electrical codes.
3.4Power Cabling
Caution: When connecting the equipment to the power sources, check the equipment nameplate
rating to avoid overloading circuits which may cause damage to over-current protection devices
and supply wiring.
Each chassis controller has two potential power sources. One is a Power over Ethernet (
source, and the second is AUX power from an external source.
A RJ-45 connection on the controller is requi red to inte rface the Et hernet to the end user . Connec t
an Ethernet cable to the RJ-45 port. If this connection originates at a PoE switch the controller is
powered over the Ethernet connection. If on ly a PoE connecti on is made to the controller, the PoE
connection powers the controller. The AUX power connection is not required for power. If both a
PoE switch and an AUX power source connection is made to the controller, the AUX power
connection powers the controller. If a standard Ethernet (non PoE) connection is made to the
controller, the AUX power connection is required to po wer the controller.
Figure 4. 2RU Chassis Ground Location
PoE)
A PoE switch and an AUX power supply can simultaneously be connected to the controller
module. A PoE switch is designed to shut power off when the presence o f another p ower source
(AUX power) is present. If power is not provided through the AUX port the controller assumes
a PoE switch is the voltage source. During the AUX power application to the controller the
