Preparing drop cables
Perform this task to prepare the CAT5e cables that connect the ODU to the PoE power
supply.
CAUTION
Always use Cat5e cable that is gel-filled and shielded with copper-plated
steel. Alternative types of cable are not supported by Motorola.
NOTE
The maximum permitted lengths of CAT5e cables are specified in Maximum
cable lengths on page 2-5.
For
details of supported cables and recommended connectors, refer to
Installation inventories on page 4-2.
‘Main’ drop cable: To prep
are a long section of cable to connect the ODU to the LPU,
proceed as follows:
1
Cut off the approximate length required (allowing a bit of surplus), or
leave it on the drum so that it can be unwound as the cable is hoisted.
2
Slide one or more hoisting grips onto to the top end of the main drop
cable (Figure 5-7).
To determine the number of hoisting grips required,
consult the grip manufacturer.
3
Secure the hoisting grip to the cable using a special tool, as
recommended by the manufacturer.
4
Fit an RJ45 connector and gland to the top end only, as described in
Assembling an RJ45 connector and gland on
page 5-16.
