Why a crimping tool?

Are you going to do it the way of running cables all
the way from your hub/switch and putting RJ45s on them?


My advice - get some wallboxes  and RJ45 socket plates.
Then all you need is a punchdown tool.
And think of using a patch panel at the other end.

Yes - you DO need to borrow a crimper here, but to make the patch 
cables only.

Oh - and remember there is a big difference between stranded
and solid Cat5 cable.
The cheaper, solid Cat5 cable is used for the runs between
patch panel and wall or desk socket.
It is attached to the RJ45 sockets using a punchdown tool.
Solid cable is not suitable for repeated bending, hence the
use of:

Stranded Cat5 cable, terminated by RJ45 plugs, for patch cables.

Don't get solid and stranded cable mixed up. Ahem....
(Several hours of sweat and swearing went into that little mixup...)

Yes - beg or borrow a Cat5 tester.
Just a low-end one with the set of blinking LEDs which tell you
that the wires are connected, and in what order.
You'll have no end of headaches if you don't do this.

Also get yourself  something to push rope or
cable  through ceiling voids - say a dicarded section of plastic
trunking.
