Assembling an RJ45 connector and gland
Perform this task to prepare the outdoor CAT5e cable with connectors and glands.
Safety precautions
The metal screen of the drop cable is very sharp and may cause personal injury.
When preparing the drop cable, take the following safety precautions:
• ALWAYS wear cut resistant gloves (check the label to ensure they are cut resistant).
• ALWAYS wear protective eyewear.
• ALWAYS use a rotary blade tool to strip the cable (DO NOT use a bladed knife). To use
the rotary blade tool, fit it around the outer cable sheath and rotate the cutter around
the cable once or twice. The stripped outer section can then be removed.
Assembly
Assemble the drop cable as shown in Figure 5-6. The gland is only required for outdoor
connections at the ODU or LPU. The connection to the PoE power supply requires the RJ45
plug but no gland.
