CPRI Cable Boxes • In First Phase of project →For few sites material • CPRI cable will be in the RRU box • Each CPRI cable box contains 30m

→ Remaining sites material • CPRI cable boxes are independent from RRU box • Each box will have cables of different lengths

→ CPRI boxes are of same size (H122mm X L384mm X W365mm) for all sites. → Depending on total CPRI cable length required, 1 to 3 boxes may be required per site. Pack ALL CPRI boxes for one site together in a single wrapping stretch film.

Part II: Installation

Pre-Requisites: Safety First Post warning signs in areas where high-voltage cables are installed Post ‘off limit’ signs in areas where accidents are most expected. With guardrails or fences, block open areas such as connecting parts, roof, and scaffold Make sure to wear protective gear such as gloves, shoes, harness, etc. Do not wear metal objects such as Watch, Ring, Etc. Do not look into the optical cables as the laser beams are harmful for the eyes.

Pre-requisites for Installation The system DC power must be switched off before installation Check that you have Site information (address, key access, contact person, etc.) All required tools for installation (especially torque driver & hexagonal crimping tool) Approved RFE1 Checklist Check if TGB is installed or not, if not report to the Samsung

Check site environment Power supply check Feasibility of installation

Cables – points to remember • Cables for each sector should be tied together with no crossing over into the other sector • Run cables without crossing and periodic ties all the way from RRU to ODC as shown in the previous slide • Use colored insulation tapes inside the cable tray to differentiate cables in each sector. (Blue for Alpha, Red for Beta and Green for Gamma)

Cables Bends in cables should be smooth, NOT sharp. Follow minimum bending radius restrictions No crossing over of cables Do not leave any power-cables exposed Cover cable tray with packing after installation

Connectors Ensure all steps have been followed in GPS connectorization

If connector with clamping ring was used, make sure that the clamp ring was installed with hexagonal crimping tool

Tighten all connectors with the appropriate torque values Do not leave gaps (especially check RET unit-to-antenna connection & RRU connections) All screws should be fastened tight Keep the waterwater-proof caps and rubber packing to secure the unused ports

Antenna While pulling antenna up to the tower, tie the rope at the antenna clamps Tie the top and bottom ends so antenna does not swing Keep rope at enough distance from tower Two people - one at bottom and one at the top - to ensure that antenna does not touch anything on its way up

Antenna Pulling Technique

RRU While pulling RRU up to the tower, tie the rope at the center so that the RRU does not swing Keep rope at enough distance from tower Two people - one at bottom and one at the top - to ensure that RRU does not touch anything on its way up

Post-Installation Check Remove any debris produced during the work and clean up the installation site. Make sure to clean the rack before leaving the site. Remove boxes, pieces of cable from the site and discard them suitably Do NOT leave any waste at the site

Any remaining material after installation (e.g. cable, tools) should be returned to the concerned Samsung contact person

Double-check each and every aspect of the installation. Fill out the Site Installation Checklist
