N2000 CPLD update

Question

I have a large number of 2024p/2048p switches that we deployed last summer with 6.3.0.15,16 or 18 and CPLD 13. I was looking over the notes for the upgrade to 6.3.2.7 and trying to figure out the impact of the CPLD update from 13 to 15. The language of the patch notes is not worded as strongly as most of the other content, they mention you can upgrade it where for other components they tell you that you must upgrade it (like boot code), but that you MUST downgrade it to go backwards. In addition, they requirement to visit every switch and connect directly to it/power cycle it locally is a gigantic burden. Its it required to update to CPLD 15 at the same time as upgrading to 6.3.2.7?  Is is possible to go to 6.3.2.7 and stay on CPLD 13 until someone can go to each switch and do the CPLD update (weeks or months), or should we stop at some lower release, like 6.3.2.6 that did not yet have the CPLD update until we can schedule the visits?

Wanted to chime in with how we've done it (completely remotely) Updating Stack upload 6.3.3.10 code to stack (and all members) copy tftp:// /image backup Configure backup  boot system backup Backup up running config copy running-config backup-config Reload switch Reload Repeat the following for until all switches in the stack have been done Take note of which switch is the master and set the next switch to be done as standby config stack standby <#> exit exit update cpld

Hi,

It is recommended for everything to be at the latest version. It may work with the older CPLD and the newer firmware, but it would be better to have them all updated at the same time. Just updating the firmware to a version that doesn’t need the newest CPLD is the best option.

We have three Dell Networking N2048 units in a stack. I upgraded from 6.3.2.3 --> 6.3.3.8 today. Going by the included PDF upgrading guide, I attempted to telnet into the stack and issue the command 'update cpld' to get from CPLD 13 --> CPLD 15.

The console line showed that it was issuing the CPLD update command and after about a minute it printed a new line saying that it successfully issued the update command and returned me to my enable prompt.

However, when I go back into the console and issue 'show version' my CPLD version is still 13. I can't seem to get it to update the CPLD version to 15 from the stack master. Any help is appreciated.

Same issue with a stack of 2 N2024s. Connected by SSH.

Sorry just wanted to get some more information. So by setting a stack member as standby what does that achieve?

Your solution is good, but it will not work on stack with only 2 members. I can't demote the current Mgmt switch to standby. Example:

SWCORE_01_MRT02#show switch
    Management Standby   Preconfig     Plugged-in    Switch        Code
SW  Status     Status    Model ID      Model ID      Status        Version
--- ---------- --------- ------------- ------------- ------------- -----------
1   Stack Mbr  Cfg Stby  N3048         N3048         OK            6.1.0.6
2   Mgmt Sw              N3048         N3048         OK            6.1.0.6

Whenever i try to put switch2 as standby i get this message

SWCORE_01_MRT02#configure
SWCORE_01_MRT02(config)#stack
SWCORE_01_MRT02(config-stack)#standby 2
Error: Management unit cannot be set as Standby

Maybe i'll have to deal with uploading the startup-config to a tftpd server, edit the "standby" line and download it again to startup-config.

Use the 'update cpld unit' when upgrading to newer firmwares.

update cpld 2 this will update switch 2 in the stack.   update cpld 3 this will update switch 3 in the stack.

Hi,

Can you confirm that all 3 switches are running the same firmware and CPLD? Are the other 2 switches, console serial are able to access? Can you also confirm with the stack cables, are seated properly? Have you also tried rebooting the switch? In your situation, reboot switch 2 and wait for it to be fully loaded then move on with switch 3.
