Dear Expert,
My customer has N7K SUP1 with HA as below and I need to replace 2 with SUP2E 6.1.2 from SUP1(6.1.1).
As per Cisco document, it is required EPLD upgrade from SUP1 to SUP2E with Fabric-2 module, but there is no guide time for EPLD.
Mod Ports Module-Type Model Status
--- ----- ----------------------------------- ------------------ ----------
1 0 Supervisor module-1X N7K-SUP1 active *
2 0 Supervisor module-1X N7K-SUP1 ha-standby
3 48 1000 Mbps Optical Ethernet XL Modul N7K-M148GS-11L ok
4 48 1/10 Gbps Ethernet Module N7K-F248XP-25 ok
5 24 10 Gbps Ethernet Module N7K-M224XP-23L ok
Mod Sw Hw
--- -------------- ------
1 6.1(1) 3.0
2 6.1(1) 3.0
3 6.1(1) 1.3
4 6.1(1) 1.0
5 6.1(1) 2.0
1. Can I have no downtime to do this activity ?
As per Cisco HW installation guide, It seems I should replace 2 SUP at same time, but if I can replace separately, please let me know.
2. How many minute is required for upgrade EPLD with above HW inventory ?
I assummed this time about 1hr ~ 90 min(max), is it correct ?
3. If this upgrade is failed, then I need to rollback from SUP2E(S2-6.1.2) to original SUP1(S1-6.1.1).
Is below step is correct for rollback ?
- Turn off the power to the switch
- For each Supervisor 2E module installed in the switch, remove the module and replace it with a Supervisor 1 module.
- Power on and verify all module is fine, sh version to check to rollback to S1-6.1.1.
- Run ‘install all epld bootflash:n7000-s1-epld.6.1.1a.img parallel’ after rebooting with original SUP1.
- Verify configuration and status
4. when I downgrade to n7000-s1-epld-6.1.1a, only linecard will be downgrade > or All SUP and FAN or Power module EPLD also downgrade ?
If so, how many minute will re required with previous HW inventory ?
I assummed this time about 40 ~ 60 min(max), is it correct ?
5. From S1-6.1.1a to S2-6.1.2a upgrade, will N2K FEX Software be upgrade as well ?
I need to update this downtime by tomorrow morning, so I seek your advice urgently.
Please share your experinece with me, thanks in advance.
Jason.
