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
transition from PoE to AUX is seamless. If AUX power is discontinued there is an interruption
of power and communications to the controller before power is supplied by the PoE switch.
3.4.1AUX Power
Refer to Chassis Controller Installation Instructions (ADCP-92-311) for AUX power details.
3.4.2Interface Connection
Ethernet Port (RJ45 Connector) PoE Switch
Connect the wiring to the Ethernet RJ45 jack on the PoE switch. Plug the other end of the
Ethernet cable into the controller at the back of the chassis. The Ethernet port supports a
maximum cable length of 328 feet (100 meters) to a switch. Pins 1, 2, 3, and 6 (See Figure 5)
are used in 10BASE-T (10Mb/s) and 100BASE-T (100Mb/s) networking. Set PoE switch to
auto-negotiate, the controller Ethernet port supports 10/100Mb/s.
Figure 5. RJ45 Connector Wiring
When bringing Ethernet cable into the chassis, make sure that cable is run vertically along the
left or right side of the bay. Route Ethernet Cable to the rear of the chassis. Secure cable to
chassis using tie points provided. Leave enough cable slack to make connection to the
appropriate location on the Controller.
Note: All Ethernet or PoE cabling should be routed away from any sharp edges and
properly secured in place to prevent chafing and to provide strain relief. This may be
achieved by tie-wrapping the wires to the rack frame or by a similar means.
3.5Blade Installation
Several single-mode or multimode blades are available for installation in the network chassis.
They are LC-to-MPO, LC-to-LC, and MPO-to-MPO. For cable clamping and management
reasons mixing of fiber cable fanout types in a single chassis is not recommended. A blank
cover (Catalog # QBCB-HR), one per slot is available to fill unused slots in the chassis. Blade
slots are numbered at the left side of chassis, starting with one at the top.
Note: Remove dust cap, inspect, and clean MPO connector per ADCP-96-150 instructions
before terminating. Remove the ferrule dust cap from one of the patch cord connectors and
then clean the connector as spe cified in the Optical Fiber Connector Wet and Dry Cleaning
Instructions (ADCP-90-159) or by locally approved procedures.
When the blade is fully pushed into the chassis it is connected to the back plane. The blade
remains connected to the back plane at the first detente position. When the blade is pulled out to
the second detent the blade is disconnected from the back plane. When the blade is fully pushed
into the chassis it is reconnected. Refer to
Figure 6
.

a. If Managed Fiber Cables are used attach cables to appropriate adapters.
b. If LC to MPO blades are used attach MPO cables to appropriate adapters.
7. Make sure to route the Managed Fiber Cables right or left as determined by the side of the
chassis the cables are entering from. Route Managed Fiber Cables through cable
management system to the front of the chassis and attach to proper adapters.
Caution: If blades are in one of the detent positions when fiber connections are made, make
certain that there is enough slack in the cable so that when blade is pushed in fiber bend radius
is not compromised.
8. Install blank covers in unused slots by placing the right end into the recess on the right side
of the chassis, then push the left end (latch) into the left side of the slot. Remove blank
cover by sliding latch to the right and lifting cover out of the chassis.
Blade removal is the reverse of installation. Make certain that all data passing through a blade is
rerouted before beginning the removal process.
3.6Cable Installation
Note: Remove the dust cap, inspect, and clean MPO connector per ADCP-96-150
instructions before terminating. Remove the ferrule dust cap from one of the patch cord
connectors and then clean the connector as specified in the Optical Fiber Connector Wet
and Dry Cleaning Instructions (ADCP-90-159) or by locally approved procedures.
Each fiber breakout should be secured to the rack above or below the chassis. Trunk cables enter
the chassis from the side near the rear. The method and location for securing the trunk cable is
dependent upon the cable type.
