ERS 4900 vs ERS 5900
« on: August 17, 2016, 07:09:23 PM »
Hi folks,

I'm trying to find any technical comparison between both boxes and find nothing, We're looking to upgrade our existing closets legacy switches with either 49xx or 59xx but we don't know what's the major differences between them except the prices/performance.

 Which one you prefer & you'll go with it ?..., And Why?

We are starting to move to 4950's from 5698's.  We don't have a need for uPOE, nor F-to-B airflow.
We will miss many 'legacy' features of the 5500/5600 series, but fabric more than makes up for it and is what we hope to deploy in the future.
Also, the heat load is similar between the models, while the 59XX has a higher thermal envelope.  This can be a problem in some of our closets.

Thanks BBinder and I already went through it and find it a liitle bit close ecexpt the performance for 59xx is higher with U-POE support.

Thanks TankII,
You're absolutely right the 49xx series is more likely for most of customers because it is  more simple and the streamline box which is including all parts inside without complexity as an access switch and I think 49xx may offer U-Poe in future.

Hi folks,

short summary - the ERS-5900 has field replaceable Fans, is able to have MACSec in future, 4x SFP+ instead of two and QSFP+ cables for stacking. NNI-NNI Feature is now available for both.
