Advice on ISR G2

Hi,

I'd like to scale my lab with a mix of ISRs G1 & G2.

My question is about 1921 vs 2911. The main concern is fan noise.

As we know 1841 is very quiet, does anybody know if 1921 is quiet too? We also know that 2811 is a little noisy; the 2911 is noisy too?

  • I have a 2911 on my desk to lab stuff on and the noise is hardly noticeable. I think the 1900 series is about the same on noise level.

    During boot up process almost all the routers/swtiches makes a little noises. You may have to wait 1 or 2 minutes in order to find it silent. Cisco2911 might difinitely have more noises as compared to Cisco1921 due to its capacity and number of fan.

    As the level of router increases, level of noise increases due to high processing power and it's cooling fans. During boot time it generates noise but later noise decreases. 

    I have 2 7200 series VXR which makes noise at first during boot time but later it's ok the noise are considerable.

  • Hi,

    Regarding cisco 1921, the noise level is very low or quiet same as 1841 or better. I bought one from

    ebay last week.

  • Hi,
    Thank you!
    I bought 1x 2901 and 1x 2911.
    2901 is very silent, 2911 makes noise during boot time, but it's acceptable noise.
