Safety Guidelines for Equipment Installation

When performing hazardous work or entering potentially hazardous area wear protective equipment, such as safety belt / head or eye protection.

Smoking or open flame are prohibited on operation area.

Properly remove and dispose of all unused hazardous materials.

Comply with hazardous material documentation and reporting requirement.

After using power tool or any other equipment, they must be cleaned and put in storage on daily basis.

Keep all tool within designated work area.

When cutting any kind of material safety glasses must be used .

When handling conducting cable, the cable ends must be taped & insulated.

All accidents on-site must be reported to appropriate personal immediately.

C-Node Installation Unpack and inspect received equipment for any damage and missing material Site preparation as per define layout. Mount C-node sub rack in 19" rack. Fasten the sub rack to the 19" rack with appropriate (M6) screws. Ensure proper length and routing of fiber/E1s cables. Use Flexible pipe for fiber patch cord when laid out of 19" rack .

DDF Installation

The E1 cable is to be stripped with sufficient length to reach DDF, unused wires to be cut and PVC tape must be used at the ends.

The E1 cable must be arranged and neatly run around the 19" rack to the DDF panel.

No extra cable should be left in side the rack. Grounding of DDF/DDP must be ensured. DDF/DDP should be installed at bottom of rack.

Cable layout &Termination

E1s cable and DC, AC power cable must be run separately along the cable rack as standard rule for cable management.

Use flexible pipe for power cable/ optical fiber patch cords. Use surge arrestor for IF cable. All grounding cable must be of shortest possible length.

Common Rule for Equipment Grounding

Yellow-Green color grounding cable. Should be laid with shortest length. Thimbles must be as per cable size. Use proper crimping tool to crimp the thimble. Grounding resistance less than 10 ohm. Ground connections must be securely tighten. No multiple connections with single point / thimble.

In case there is no point available for the grounding, it should be informed to the TP implementation team.

Grounding of surge arrestors.

Labeling of equipment

Following equipment labeling is mandatory for effective O&M activity.

19" rack with near end site ID. Each hop with far end site ID. IF cables for main /stand by system. E1s cables . Fiber patch cords for end to end connectivity. Power cables for main/stand by system. Rectifier circuit breaker for NEC equipment. DC PDB branch circuit breaker with far end ID. Surge arrestor for main/stand by system. DC PDB labeling if more than one PDB is installed at the site.
