CTR 8540 GETTING STARTED: INSTALLATION
Function/Requirement Priority Details
Restricted access
Required Rack Space
The CTR and its associated dc power supply must be installed in a restricted access area such as a secure equipment room, closet, or cabinet.
CTR requires 44.5mm (1RU) of vertical rack space and 300mm rack depth (CTR chassis depth is 240 mm).
Ventilation
CTR requires unobstructed air passage to each side for ventilation purposes. There must be a minimum of 50mm (2”) of side spacing to any rack panels, cable bundles or similar. No space above or below is required for ventilation purposes.
Maximum Ambient Temperature
CTR is specified for a maximum ambient temperature (Tmra) of +55°Celsius (131° Fahrenheit). This ambient applies to the immediate operating environment of the CTR, which if installed in a rack cabinet , is the ambient applying to its location within the cabinet.
Physical stability
Ensure that adding a CTR to a rack does not adversely impact the physical stability of the rack.
Power Supply -48 Vdc
The CTR and optional PWR modules have the +ve pin on their dc power supply connector connected to the chassis .
It must be used with a -48Vdc power supply which has a +ve ground; the power supply ground conductor is the +ve supply to the CTR.
The power supply must have an accessible power disconnect device (main switch).
Power Supply +24 Vdc An external 24 Vdc to -48 Vdc converter is requir ed at sites using 24
Vdc powering.
D.C. Supply Ground Con­nection
CTR equipment has a connection between the earthed conductor of the d.c. supply circuit and its earthing conductor.
CTR equipment must be connected directly to the d.c. supply system grounding electrode conductor or to a bonding jumper from a grounding terminal bar or bus to which the d.c. supply system grounding electrode is c onnected.
Switching or disconnecting devices must not be in the grounded circuit conductor between the d.c. source and the point of connection of the grounding electrode conductor.
o
The CTR chassis must be grounded to the station or master ground, which must be the same ground as used for the dc power supply system.
o
Normally this is achieved by grounding the CTR to the ground bar in its equipment rack or frame. This bar is most often located to one side of the rack or at rack top or bottom. In turn, the ground bar is grounded to the station ground.
Equipment Location
CTR must be located in the same immediate area (such as, adjacent cabinets) as any other equipment that has a connection between the grounded conductor of the same d.c. supply circuit and the grounding conduc tor, and also the point of grounding of the d.c. system. The d.c. system shall not be grounded elsewhere.
Location of D.C. Power Sup­ply
The d.c. supply source for CTR equipment must be located within the same premises as the CTR equipment.

D.C. Supply Compliance, Loading and Protection
Cable routing CTR Cat5, tributary, auxiliary and NMS cables are not to be routed
CAUTION: There must be a minimum of 50 mm (2”) of side spacing from the CTR to any rack panels, cable bundles or similar to ensure proper ventilation.
The dc power supply must be UL or IEC compliant for a SELV output (60Vdc maximum).
Check to ensure that connection of a CTR system to a new or existing dc supply does not overload the supply, circuit protection devices and wiring.
CTR and optional PWR module must each be supported from a dedicated circuit breaker located on their rack power distribution panel. The circuit breaker(s) should have a rating of 20A.
The circuit breaker(s) must be used as the CTR power connect/disconnect devices - do not use the front panel connectors as connect/disconnect devices.
with any AC mains power lines. They are also to be kept away from any power lines which cross them.
Installation Procedure
This procedure is for rack-mounting CTR 8540.
1. Fit the rack mounting ears to the chassis with the grounding stud to left or right side for the most direct ground wire path to the rack ground bar.
2. Locate the CTR in the equipment rack and secure it using four No.12 Phillips dome-head screws from the CTR installation kit.
3. Ground the CTR from the grounding stud to the rack/frame ground bar using a length of 4mm2 (AWG12) green PVC insulated stranded copper wire with a suitably sized ground lug at the ground bar end (supplied by the installer). The grounding stud accommodates ground cables up to 16 mm (AWG 6). The stud also provides jack plug connection for a wrist strap.
4. If the equipment rack/frame requires grounding, use 16mm2 (AWG6) wire from its ground bar to the station ground.
Grounding Safety:
o
Do not assume an existing rack or mounting frame is correctly grounded. Always check the integrity of the ground connections, which must include a check through to the master ground for the station. The master ground bar should be located at the point of cable entry to the equipment building. Ground wires must provide a direct, low impedance path to the master ground bar.
o
Do not connect other equipment to the same grounding cable as the CTR. Each item of equipment in a rack must be separately grounded to the rack ground bar.
o
The CTR must be located in the same immediate area (adjacent racks/cabinets) as all other equipment with a (ground) connection to a common DC supply source.

5. Install the SD card in the slot at the rear of the CTR chassis. NOTE: CTR must be powered OFF when installing or removing the SD card.
o
The SD card holds the SW load, default/current configuration, and as­ordered capacity and feature licenses.
n The SD card is identified by a unique serial number, which identifies
a terminal for capacity and feature license purposes. It also retains copy of the current terminal configuration, and the previous configuration for roll-back purposes.
n If the SD card is transferred to another terminal, the new terminal
assumes the identity of the previous terminal.
o
Insert the SD card into the slot label-side up, and carefully push-in until it clicks home.
o
To remove the card, push-in to release.
6. Fit Ethernet RJ-45 or fiber cables as required. For fiber, first install the required SFP option.
7. Fit E1/DS1 tributary cables as required. For information on the available tributary cable sets, refer to the CTR 8540 Installation Guide.
8. Carry out a complete check of the installation. When checked and correct:
o
If option modules are to be installed, proceed to the next topic.
o
If no option modules are to be installed, CTR is ready for connection to power. See Power Supply on page 9.
CAUTION: Ambient temperatures must not exceed 550C (1310F). If installed in a rack cabinet, it is the ambient within the cabinet.
Adding Modules to CTR
Plug-in modules are used to provide platform PSU redundancy, radio interfaces to Aviat ODUs or IRU 600, auxiliary data and alarm services, and PoE+ RJ-45 con­nections to external devices.
Modu le s can be insta lled prior to or aft er ini tial CTR power-on .
CAUTION: Install plug-in modules in their assigned slot positions, and check their front panels are flush-fitted (not protruding) and held secure by their fasteners (finger-tighten - do not over-tighten).

l A D-sub M/F 2W2 connector is fitted at one end, wire at the other. l The cable is nominally 3m (10ft). The wires are 4 mm2 (AWG12). l The blue wire must be connected to live (-48 Vdc); the black wire to ground
(+48 Vdc).
Figure 1-6. Power Cable and Connector
CAUTION: Do not use the DC power connector as a power con­nect/disconnect device. Always use the associated rack-mounted cir­cuit breaker for this purpose.
Fuses
The chassis and PWR modules are fitted with a fast-acting 25A fuse. The fuse is not field-replaceable.
Power Cable Installation
These steps describe the procedure for installing the power cable, in preparation for power-on.
Do not connect the power cable to the CTR or to a PWR module until:
l CTR installation has been completed, with SD card, Fan module, and option
modules fitted.
l Management access has been prepared.
To install the power cable:
1. Run the supplied power cable through to a dedicated circuit breaker on the rack power connect panel. The circuit breaker should have a 20A rating.
o
For back-up power using a PWR or PWR+AUX module, its power cable must be to a separate dedicated circuit breaker. The circuit breaker should have a 20A rating.
o
The circuit breakers are the power disconnect devices for the CTR. Do not use the front-panel connectors for live power connect/disconnect.
4. Trim to length, and connect the blue wire to -48Vdc (live), and the black wire to ground/+ve. Trim the cable braid back to the cable sheath.
5. Measure the voltage on the dc power connector. The voltage should be ­48Vdc, +/-2Vdc for a non battery floated supply, and nominally -56 Vdc for a battery floated supply. (Operational limits are -40.5 to - 57 Vdc).
