About Nexus 7018 power supply

[caobo1020]

Hi,

I have four power supplies(N7K-AC-7.5KW-US) installed in Nexus 7018. Are there any differences between the four PSUs? The reason I ask this is that for some Juniper models. The order of the PSU matters, say PSU0 and PSU2 support the half line cards of the chassis, PSU1 and PSU3 support the rest line cards. Does cisco have the same design?

e.g.

Let's say the capacity of two PSUs is enough to support the output power. In the following scenarios, we lost two PSUs. Does the two cases have the same impact or have no impact to the system?

1. failure(PSU1, PSU2)

2. failure(PSU1, PSU3)

Thanks,

Bo

Hi Bo,

There is no difference in the power supply models. There are different modes in which the power supplies can be configured and is explained in the following link:
