RPS 2300

[Madhan Kumar]

Hi all,

My client is using RPS 2300 redundant power supply system for Cisco 3750G switches. It is having 750w  power source module. For how many switches it will act as a backup power source at a time?.

Thanks & Regards

It will be the powersupply for 1 3750G unit maximum.

3750e and 2560e with 1150w is not supported (for quite obvious reasons)

I would guess that thesame is to be said about the 3750x and 3560x.

good luck

Hi hobbe,

Thanks for your reply.

If it is supporting only one switch at a time , what is the purpose of using RPS?.

If I want to make this device to support all the availabe switches, what I have to do?.

Thanks & Regards

Take a look at this:

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps7148/ps7130/prod_presentation0900aecd805bbf15.pdf

It should support 2 switches, depending on model and power requirements.

It is for protecting a switch from an internal powersupply error or accidental knockout of a powercable.

it can maximum support 2 switches at the same time.

if you add another powersupply it will support 2 units simultaniously out of the 6 that is the max available to install cabeling on

so if you install 6 3750G on a rps 2300 it will monitor and protext all of them from internal powersupply error or if the power gets accidentally dislodged but it can only provide power to a total of 2 switches of the 6, at the same time.

it will not be able to take the load of all 6 switches.

if you need all 6 to be able to function the you need the 3750x with powerstacking and dual powersupplys.

that way you can have up to 8 different powersources for 4 switches and 4 for the other two.

or the rps 2300 to cover all of them at the same time as they can have dual powersupplys.

Good luck
