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.
3.4 Power Cabling
Each chassis controller has two potential power sources. One is a Power over Ethernet (
PoE)
source, and the second is AUX power from an external source.
A RJ-45 connection on the controller is required to interface the Ethernet to the end user. Connect
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 only a PoE connection 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 power the controller.
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 of another power 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
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.

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.
3.4.1 AUX Power
Refer to Chassis Controller Installation Instructions (ADCP-92-311) for AUX power details.
3.4.2 Interface 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.
3.5 Blade 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: 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.
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 specified in the Optical Fiber Connector Wet and Dry Cleaning
Instructions (ADCP-90-159) or by locally approved procedures.

3.6.4 MPO Trunk Cable Installation MPO to MPO Blade
When using trunk cables the fiber breakout is normally secured to the rack above or below the
chassis. A grommet fitting secures the cables at the chassis entry point. From the grommet, the
optical fibers are routed to the adapters at the front of the blade. Use the following procedure to
install the cable:
1. Locate the cable entry location that is specified for cable installation.
2. Route cables to chassis securing cables and breakout to rack per local practices.
3. Assemble grommets and cable clamps on fiber cables as shown in Figure 15.
4. Cable clamps and several grommets are provided with the cable clamp kit for securing
cables to the chassis. More than one grommet may be needed to secure cables in the clamp.
