Yes. If there is no single point of failure there (like "both switches
only have a single power supply and are connected to the same UPS outlet"),
then you do not need the CR1-CR2 link.
(Interestingly enough, a few years ago I built a customer setup that did
not have this link, because I said "well, there's two switches here, with
two power supplies, two supervisors, 2x GE link bundles, this is just not
needed" and the customer *insisted* on having the extra link there "just in
case"... :-) )
