We have one cisco Nexus 5548UP L2 switch running very old software 5.0.3 version but recently i got 7.0.1 software from someone else (we don't have SmartNet on this switch).

is it safe to upgrade from 5.0.3 to 7.0.1? I was trying to find prerequisite but i didn't find any so wonder if some already did in past please share your experience.

UPDATE

after upgrade from 5.0.3 to 5.2.1 (for safety) look like my fan speed bump up from 50% to 60%. here is the show env output

Before proceeding with any upgrade, please ensure you have both the kickstart and the system image file. The kickstart file will set all the variables for you, and the system will check for this on reload.

NOTE: The kickstart file needs to match the system image file version. Please do not try to proceed with upgrading without both of these files.

The quickest way to determine if you are able to upgrade this device is by issuing the show install command from the 5548:

show install all impact kickstart bootflash:

Example Output:

switch-1# show install all impact kickstart bootflash:n5000-uk9-kickstart.4.2.1.N1.1.bin
system bootflash:n5000-uk9.4.2.1.N1.1.bin

Please also refer to the official documentation for upgrading from that version: http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/upgrade/503_N1_1/n5k_upgrade_downgrade_503.html?referring_site=RE&pos=1&page=http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/upgrade/513_N1_1/n5k_upgrade_downgrade_513.html

  • I have upgrade from 5.0.3 to 5.2.1 version for safety but look like my FAN running on max speed. what is the standard RPM speed for this switch? my fan running on 60% speed 1 1 Front-to-Back 60 15517 – Satish Aug 3 '16 at 19:14
  • You should see a log entry for this, but the normal thresholds are between 7950 RPM and 12500, however if the environment is warmer or the switch is under high load that could be completely normal. If this is only intermittent I wouldn't worry to much. A show environment should be a tell to any potential issues. – Brian Winning Jr. Aug 3 '16 at 19:24
  • Before upgrade speed was 50% but now its 60%, we are not in production its sitting in the LAB without any traffic – Satish Aug 3 '16 at 19:56
  • If environmentally there are no issues, and the temperature is not high in the room I would troubleshoot the hardware, there are many forums for users of this device of things to look at. If that yields nothing, I would open an RMA with Cisco. – Brian Winning Jr. Aug 3 '16 at 20:08

Looking at the Release Notes usually tells you about supported upgrade paths. In your case, you don't have a choice. Basically - try it. Follow the directions in the Cisco Nexus 5000 Series NX-OS Software Upgrade and Downgrade Guide, Release 5.0

Also might look at the following.

Cisco Nexus 5500 Series Release Notes, Cisco NX-OS Release 7.x 09/Jun/2016

Cisco Nexus 5500 Series Release Notes, Cisco NX-OS Release 6.02 01/Jul/2014

  • switch(config)# boot system bootflash:n5000.bin switch(config)# boot kickstart bootflash:n5000-kickstart.bin – Ronnie Royston Aug 3 '16 at 20:30
