Hi,
today I updated two of our Nexus 5548P switches and on both I recieved the message
Images will be upgraded according to following table:
Module Image Running-Version New-Version Upg-Required
------ ---------- ---------------------- ---------------------- ------------
1 system 5.0(3)N1(1c) 5.0(3)N2(1) yes
1 kickstart 5.0(3)N1(1c) 5.0(3)N2(1) yes
1 bios v3.5.0(02/03/2011) v3.5.0(02/03/2011) no
1 power-seq v3.0 v3.0 no
3 power-seq v2.0 v2.0 no
1 uC v1.2.0.1 v1.0.0.14 no
after updating to "5.0(3)N2(1)" and rebooting I see a differnce in uC on both machines!
nexus1# show version |grep uC
uC: version v1.0.0.14
nexus2# show version |grep uC
uC: version v1.2.0.1
Both switches are pure switches without extension boards and without extenders.
Is anyone able to tell me why the linux kernel has been downgraded on one switch and not on the second one? (After telling me that it will be done on both?!)
And why is it downgraded at all?
Any ideas what's going on?
BTW: The whole 'show version' of both switches looks the same (except the uC). Here is one:
Software
BIOS: version 3.5.0
loader: version N/A
kickstart: version 5.0(3)N2(1)
system: version 5.0(3)N2(1)
power-seq: Module 1: version v3.0
Module 3: version v2.0
uC: version v1.0.0.14
BIOS compile time: 02/03/2011
kickstart image file is: bootflash:/n5000-uk9-kickstart.5.0.3.N2.1.bin
kickstart compile time: 6/13/2011 6:00:00 [06/13/2011 13:43:33]
system image file is: bootflash:/n5000-uk9.5.0.3.N2.1.bin

Hello
We have replaced a defect hardware this week and we got following answer from Cisco TAC about the difference in the uC version:
The uC is a very little code which helps loading kickstart image. It's a kind of BIOS if you like. It has nothing to do with the system image (for example n5000-uk9.5.1.3.N1.1.bin). So on the new card you got a new version of it.
