VDX 6740 nos 4.1.3a

So I just got these VDX 6740 switches.  First time I've seen a brocade switch.  They are running NOS 4.1.3a.  Is this bad or old or something?  Should I upgrade?  How?

Hi there,


My VDX just arrived 2 weeks ago. The vendor said it has the newest version: 4.1.3a.

They said, only the Vendor and the Vendor Partner can download the firmware.


I cannot find any link about latest release notes of VDX6740's firmware/NOS.

4.1.3a is not the latest version. 5.0.1d is the target path for all Brocade VDX platforms. 6.x is the latest.

if you want to upgrade the firmware, use FTP server or USB device (Only Brocade USB drive)  to upload the firmware on the switch.

Personally, i would recommend "Filezilla FTP server". 


After uploading, do the command


switch# firmware activate


and reload the switch


Complete procedure is written in the NOS Admin Guide in a detailed manner. Please refer it for more information.
