4003 switch running set based OS

[mulhollandm]

folks

i have a cat 4000 (2 1/2 years old) running a set based OS but i want to upgrade it to a newer IOS - is this possible?

i know i may be restricted by ram etc but i really don't care cos all i want is to move to a standard IOS

thanks to anyone taking the time to reply

Since you have a 4003, you would have a Sup1 Engine(WS-X4012). It cannot run IOS. To run IOS you would need one of the following Supervisors

Sup2+-->WS-X4013+

Sup3 -->WS-X4014

Sup4 -->WS-X4515

Sup5 -->WS-X4516

Note that you cannot install any of the above in a 4003 chassis. So you would need to replace both your chassis and Supervisor if you want to run IOS

thanks for the prompt reply - that what i call a responsive forum!

sounds like an expensive upgrade so i suspect i'll stay with the exsting OS

No problem.. You might want to keep in mind that 4003 chassis and WS-X4012 are end of life. Here is the EoL announcement
