There should be. You will need one. RL02 cabling and terminators is
a frequent topic here. The terminator is identical for the RL01/RL02
and RK06/RK07. The round cables are not (one has all the pairs, one
has enough pairs for its controller but not the other, but the pairs
they have in common are identically placed).

There is no difference between RL01 and RL02 cabling and you can mix
them on the same controller at the same time. I did this myself when
I owned an 11/23 w/RLV11 and an RL01 (borrowed from my PDP-8/a) and my
boss loaned me an RL02 that we used to transport data/code to/from the
customer site (our datafiles were over 5MB so I _needed_ an RL02 and
they were a couple of grand back then).

Typically, the RL11 gets set for the primary CSR (I don't remember
without checking the docs how the vector is set), and unless you want
to put a second RL11 in the same machine (unusual), you pretty much
never change the jumpers.

Before first power-on? Depends on how long it's been since it was
last powered up (PSU checkout and such). The thing you'll want to do
before using it is to open the lid and check for the head lock before
mounting a pack and putting it online. Do notice if all your
lightbulbs work. I rarely use WRITE LOCK, so I borrow that bulb if
any of the others burn out.
Do wipe down the cartridge area with a lint-free wipe (I have a pack
of kimwipes I bought for such purposes) moistened with some IPA
(isopropanol / 1,2propanol) Get any loose dust off the interior
