Chapter 1- Hardware Description Safety Requirements This section describes the requirements your site must meet for safe installation and operation of the system. Site Safety Requirements For your protection, please read these safety instructions completely before operating the equipment. 1-6 • Look carefully for potential hazards in your work area: moist floors, ungrounded power cables, frayed power cords, missing safety grounds and so forth. • Locate the main circuit breaker within the room.
Polycom RMX 4000 Hardware Guide General Installation Precautions Attention: The RMX 4000 can weigh up to 40kg when all slots are occupied. Two people are required to lift the MCU out of the box and also when installing it in a rack. • Use a regulating uninterruptable power supply (UPS) to protect the RMX 4000 from power surges and voltage spikes, to keep your MCU operating in case of a power failure.
Chapter 1- Hardware Description • Always keep the rack’s trays and card’s slots closed when not servicing, to maintain proper cooling.
Polycom RMX 4000 Hardware Guide Make sure that boxes contain all the required parts. 4 Remove the boxes and top Stratocell®. 5 Holding the handle on each side, lift the RMX 4000 from the box, and place it on a flat surface or install it in a rack. Remove any packaging material prior to positioning the RMX 4000. Attention: Two people are required to lift the MCU out of the box and when installing it in a rack.
Chapter 1- Hardware Description Installing the RMX in a Rack or as a Standalone Either place the RMX 4000 on a hard, flat surface such as a desktop or mount it on a 19”/23” rack. Standalone RMX 4000 Installation Place the RMX 4000 on a flat surface or desktop. The RMX 4000 must rest on the four feet at the base of the MCU and must be shifted or moved into position using the two handles attached to the front.
Polycom RMX 4000 Hardware Guide Placing the RMX 4000 in a 19” Rack 1 When the RMX is to be rack mounted chassis runners must be installed on the rack as shown in Figure 1-2. Two chassis runners are included in the Rack Installation Accessories kit and are attached facing inward from the outside of the 19”/23“rack mount. Figure 1-2 Installing chassis runners and RMX in a rack 2 Mount the RMX on top of the rack brackets using the blades or placing it on a rack mount shelf with runners.
Chapter 1- Hardware Description 3 Fasten the RMX to the rack with 8 screws into the holes provided on the RMX’s front as shown in Figure 1-3. Figure 1-3 RMX 4000 Rack Mount Rack mounting screws must be supplied by the rack’s manufacturer. The airflow of the RMX 4000 is from right to left. Be sure that the areas on the left and right side of the system are clear for proper ventilation. When the unit is installed on a rack, the rack must be properly grounded to the central office ground.
Polycom RMX 4000 Hardware Guide Placing the RMX 4000 in a 23” Rack 1 Mounting the RMX 4000 on a 23” rack requires that first the handles and then the 19” brackets be removed from the MCU. This is shown in Figure 1-4. Figure 1-4 Removing and attaching 19” and 23” brackets 2 After removal, attach the 23” brackets as provided in the Rack Installation Accessories kit, and re-install the handles to the 23” brackets. This is shown in Figure 1-5.
Chapter 1- Hardware Description The airflow of the RMX 4000 is from right to left. Be sure that the areas on the left and right side of the system are clear for proper ventilation. When the unit is installed on a rack, the rack must be properly grounded to the central office ground. The rack must be grounded with two-hole compressiontype connectors using copper conductors (tinned or untinned). Wire, bus bar or braided strap connectors are acceptable.
Polycom RMX 4000 Hardware Guide 3 Place the RMX in a rack and tighten the 8 screws securing the RMX to the rack. Connecting the RMX 4000 to Power Sources You can connect either an AC Inlet or to DC power according to the power system required at your site: • For systems with AC Power, up to three power supplies can be installed with one being redundant (n+1).
Chapter 1- Hardware Description • Listed fastening hardware must be compatible with the materials being joined and must be preclude loosening, deterioration and electrochemical corrosion of the hardware and joint materials. Connecting the RMX 4000 to AC Power 1 • Do not connect the green or green-yellow wire to the system single-point ground screw. • • Customers are required to only use AC power cables supplied by Polycom.
Polycom RMX 4000 Hardware Guide Connecting the RMX 4000 to -48DC SELV Power 1 On the DC Power Rail Modules (PRM’s), set the two circuit breakers to OFF. 2 Ensure that the cables from the Main that supplies electricity to the DC power units are OFF or disconnected. 3 Remove the transparent plastic caps on the terminal block.
Chapter 1- Hardware Description 5 Connect the green or green-yellow wire to the system single-point M6x15 “Ground” bolt. The rating of the protective earthing conductor should be a minimum of 10AWG. If the unit is rack mounted, the single-point ground on the MCU must be connected to the rack with a single conductor and fixed as to prevent loosening. When using bare conductors, they must be coated with an appropriate antioxidant compound before crimp connections are made.
Polycom RMX 4000 Hardware Guide Connecting Cables on the RMX 4000 To connect the cables (AC and DC systems): • RTM-IP 4000: — Connect the Management Network cable to LAN 2. — Connect the Signalling cable to LAN 3. — Connect the Shelf Management cable to LAN 6. • For each installed RTM LAN - Connect the LAN cable to LAN 2. • For each installed RTM ISDN: — Connect the E1/T1 cables to their PRI Ports. — Connect the LAN cable to LAN 1.

RTM ISDN The RTM ISDN card connects directly to an MPM+. The RTM ISDN card routes data between the MPM+ cards and components of the system, converts ISDN T1/E1 media to IP packets and provides connectivity to external ISDN networks.
Chapter 1- Hardware Description ISDN/PSTN Clock Source Each RTM ISDN card has its own primary and secondary clock source. The first span to synchronize becomes the primary clock source and the second span to synchronize becomes the secondary clock source. This clock is used to synchronize ISDN spans only (it is not the system clock). A single clock source triggers an alarm that can be turned off by setting the appropriate flag in the system configuration.
Polycom RMX 4000 Hardware Guide DC Power Rail Module A DC power rail module includes a power inlet, circuit breaker, EMI filter and backplane connectors. Power input to the system is fed via a power rail through backplane into the power supply. Each DC power rail has its own dedicated power cable. The circuit switch on the rear of the RMX activates independently any power rail installed on the RMX. An DC system has two DC rails, one for each power rail.
