Node B Rack Mount Installation Guide General Considerations The following consideration and checks are applicable to all mounting types :- The NodeB rack mount is designed for indoor use only refer to Table 5-1. Review the GPS installation guidelines (step 12) to ensure that the location will allow proper operation of the Node B GPS remote antenna. i.e.
Node B Rack Mount Installation Guide Step 4 Mounting Installations This section explains how to mount the Node B Rack Mount shelves into racks. Mounting Rack The figure below illustrates the 19inch mounting rack plus support shelves, some racks or cabinets can use support rails. This construction can be within an enclosure or cabinet. The support shelves or rails are specific to the rack, enclosure or cabinet being installed, thus their specification shall be part of same selection.
Node B Rack Mount Installation Guide Precautions The following precautions and checks are applicable to all mounting types:Connectors have been manufactured to fit their specific cables and funcition. Do not modify or force connectors. Check Site Plans for engineering approval. Ensure that good ground resistance is available at the installation site (≤10Ω) Where installed in an outdoor enclosure attention should be paid to cooling and water+dust sealing prevention refer to Table 5-1.
Node B Rack Mount Installation Guide Rack Mounting – Installing Radio Shelf Ensure the shelf or shelf supports are secure, then insert the radio shelf into the rack and secure from the front. Notes: If there is no rear access it may be required to make the ground connection prior to inserting the shelf into the rack. Where additional securing is required at the rear this shall require custom brackets depending on the rack specifications/construction. Figure 6-8 : Installing Radio Shelf Version 0.0.
Node B Rack Mount Installation Guide Step 5 Ground Installation The main Node B ground cable shall use a minimum #2 AWG (Diameter 6.6mm or CSA 33mm2) stranded wire or equivalent earth braid. The ground cable is terminated on the rear of both shelves of the Node B Rack Mount using terminal that shall fit the M8 (7/16”) stud on the rear of each shelf. The grounding wire is terminated onto the site grounding ring.
Node B Rack Mount Installation Guide Step 6 DC Power Connection-Digital The power supply input must be a nominal -48Vdc input, refer to Table 5-1. The connection of the mains to DC supply is via the cable provided as part of the digital shelf package. The provided cable assembly has 3 metres of cable with a connector to provide connection to the digital shelf. The tail ends of the cable are stripped and must be terminated to a permanent connection junction/terminal block.
Node B Rack Mount Installation Guide Step 7 DC Power Connection-Radio The power supply input must be a nominal -48Vdc input, refer to Table 5-1 The connection of the mains to DC supply is via the cable provided as part of the radio shelf package. The provided cable assembly has 3 metres of cable with a connector to provide connection to the radio shelf. The tail ends of the cable are stripped and must be terminated to a permanent connection junction/terminal block.
Node B Rack Mount Installation Guide Step 8 Inter-Shelf Connections The digital shelf is supplied with the shelf interface kit that contains the following items • I/Q interface cable – 21wayD-hybrid • Control interface cabe – 25wayD • PSU control cable – 3way The figure below illustrates the connection of each of these cables between the digital and radio shelf. Figure 6-12: Interface Cable Connection – V4A Version 0.0.

Node B Rack Mount Installation Guide Step 9 Backhaul Connections (Iub) to INC The Digital Shelf faceplate contains the backhaul connections. The installation can be selected from the following interfaces 100BaseT E3/T3 E1/T1 The connections are labeled and shown in the figure below. Note: If the Node B is in not in the same site location as the serving INC, there must be no greater than a 5 millisecond delay on the backhaul connection.
Node B Rack Mount Installation Guide 100BaseT Connection - (Eth) Terminate the Ethernet cables with RJ45 connectors and the cables may be secured to the brackets on the face of the Digital Shelf (Figure 6-14). Test the continuity for the Ethernet cables with test equipment consisting of a main and a remote unit. The termination for these interfaces is specified within the datasheets for the interfaces.
Node B Rack Mount Installation Guide E3/T3 Connections – (Tx + Rx) Terminate the E3/T3 cables with BNC connectors and the cables may be secured to the brackets on the face of the Digital Shelf (Figure 6-14). Test the continuity for the E3/T3 cables with test equipment consisting of a main and a remote unit. The termination for these interfaces is specified within the datasheets for the interfaces. The specification for both cables should be 75Ω.
Node B Rack Mount Installation Guide Step 10 Antenna Cabling - Installation Antennas and coaxial cable should be available at the site, and are part of the construction checklist and general assumptions. Two antennae per Node B Radio Shelf are optimum, allowing receiver diversity and transmit diversity (note: if option fitted), therefore two coaxial cables per Node B are needed.
Node B Rack Mount Installation Guide Step 11 Alarm Connections If local alarms are to be utilised two Dtype connectors are been provided on the Node B digital shelf. The specifications for those interface requirements are below:The maximum input voltage is restricted to 39V for a 500A 8/20 uS pulse, with a minimum working voltage of 18V. All six input circuits are the same. Figure 6-17 : Alarm Outputs & Inputs Version 0.0.
Node B Rack Mount Installation Guide Alarm Inputs The 6 external alarm inputs are connected via the 15wayD female type located on the right hand side of the digital shelf. The external alarm inputs are opto-isolated current loops. The voltage and currents shall be supplied by the external source. The pin-out for the alarm inputs are shown in the table below.
Node B Rack Mount Installation Guide Step 12 GPS Installation & Operation The Node B has an external/remote GPS antenna and receiver. The connection for the antenna (N-Type) is located on the Digital Shelf, Figure 6-18. The GPS timing signal is used by the Node B for the TDD frame timing, so that all Node B's in a network are synchronized. The GPS signal is also used by the master oscillator for a frequency reference.
