RPS 675 or RPS 2300

[rickbeare]

We have several 3750 and 3560 switchs and would like redundant power. What would be the recommended solution the RPS 675 or the RPS 2300? and why. They both seem to do the exact same thing?

Hi,

The RPS 2300 is the replacement product for the RPS 675 which went End-of-Sale last week so as of now you can only buy the RPS 2300.

Thanks, that helped quite a bit.

If I where to attach two 3750s (no PoE) On one of them, would two 750 pwr supply's be over kill ?

Then on the other one with six 3750s (no PoE) the same with two 750watt pwr supply's as well ?

Hi,

Take the case where you have two switches on an RPS with one supply. Then if the power supplies in both switches died simultaneously you'd only be able to power one of the switches. A pretty unlikely scenario, but it depends on how paranoid you are.

With six switches on an RPS with one supply there's a bigger risk as you're betting that after one failure you won't have any more failures before you can swap the failed supply. In that case you might be safer with two supplies in the RPS.

Of course, if you have 3 failures then one RPS won't help - you'd need more RPS. Like all areas of networking you need to balance the cost vs. the benefit.

HTH - plz rate if useful.
