ZXSDR RSU60E User Manual Warning! Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. Caution! Indicates a potentially hazardous situation which, if not avoided, could result in serious injuries, equipment damages or interruption of part services.
Safety Instructions This section describes the safety instructions related to electrical safety, antistatic, heavy objects and modules. Electrical Safety Instructions The following are the electrical safety instructions about tools, high voltage, power cables, holes and lightning: l Tools Use special tools rather than common tools for high-voltage and AC operations. l High Voltage Danger! High voltage is hazardous.
ZXSDR RSU60E User Manual Warning! It is not allowed to drill chassis holes without permission. l à Unqualified drilling could damage wiring and cables inside the chassis. Additionally, metal pieces inside the chassis created by the drilling could result in a short circuit. Use insulation protection gloves and first move cables inside a chassis away when drilling is necessary on a chassis. à Protect eyes during drilling as dust or flying debris may damage eyes.
Chapter 4 RSU60E l l l l Do not contact static-sensitive modules with any object that easily generates static electricity. For example, friction of package bag, transfer box and transfer belt made from insulation plastic may cause static electricity on components. Discharge of static electricity may damage components when they contact a human body or the ground. Modules should only contact materials such as an antistatic bag. Keep modules in antistatic bags during storage and transportation.
ZXSDR RSU60E User Manual l l l l Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
Chapter 4 RSU60E 4.2 Product Descripition 4.2.1 Overview ZTE Software Defined Radio (SDR) uses an architecture of separating the baseband part from the Radio Frequency (RF) part. This architecture features high integration, low consumption, flexible configuration and convenient installation & maintenance. The new generation ZTE GSM&UMTS Base Station (BS) products based on the SDR is the first SDR-based GSM&UMTS BS in the industry. It is able to help the operators have qualitative leap.

ZXSDR RSU60E User Manual Figure 4-5 ZXSDR RSU60E Panel Steps 1. Determine the target slot, hold the handle of the module with one hand, support the lower back of the module with the other hand, and try to make parallel the module and the guiding plane.
Chapter 4 RSU60E 2. Push the module slightly into the slot to more than half the depth of the slot. 3. Change the place where exercise force and then push further the module with even force. 4. Push the module until the inner side of the front panel closely touch the vertical shaft. 5. Secure the module using five M5 x 20 screws. 6. Secure the ground lug. – End of Steps – Follow-Up Action After installing RSU modules, connect the RSU power cables to the RSU power interfaces.
ZXSDR RSU60E User Manual 4.5.3 Installing Optical Fibers Between BBU and RSU Prerequisites l l The ESD wrist strap must be worn. The baseband power cabinet and the RF cabinet have been independently installed. Context When the baseband power cabinet and the RF cabinet are installed side by side or they are far away from each other, you need to connect BBU and RSU using optical fibers.
Chapter 4 RSU60E Caution! Protect an optical fiber with the winding tube when routing the optical fiber inside the cabinet. Protect an optical fiber with the corrugated pipe when routing the optical fiber outside the cabinet. – End of Steps – 4.5.4 Installing the Interconnected Cable Between BBU and RSU Prerequisites l l The ZXSDR RSU60E cabinet has already been installed. The BBU module and RSU module have already been installed.
ZXSDR RSU60E User Manual 2. Insert one end of the SFP cable to a TX/RX interface of RSU. 3. Route the SFP cable along the routing trough and cabinet sides to the FS module of BBU. The SFP cables connecting to the RSUs in slots 1 to 3 on the RF cabinet go through the left routing apertures and those SFP cables go through the right apertures if connecting to slots 4 to 6 on the RF cabinet. 4. Insert SFP cables into the interfaces TX0RX0 to TX5RX5 of the BBU FS board according to the markings 0-5. 5.
Chapter 4 RSU60E Result The RF jumpers go out from the base. The cables between cabinets must be protected with protective tubes, without any exposed part of the cables and the openings at two ends of these cables must be sealed.
