Cisco 6500 Power Supply and related configurations if any?

[SHCILDC2MHP]

Hi,

My query is with regards to the best practices deployed for connecting Cisco 6509 switches in the DC, attached is the existing and proposed setups, also would appreciate getting the related switch configs to acheive redundancy and high availability of the switches in the DC network.

Regs,

Mahesh

Hi,

this depends on what power-supplies you have and how loaded your chassis is.

For Example:

When your chassis is loaded with

     1x Sup720

     8x GE-TX Linecard (WS-X6748)

     2x 3kW Power-Supplies (WS-CAC-3000W)

Then you have to run the chassis in Combined-Mode because, even if there is no second Sup, the same power is allocated to the second sup-slot as if there were one installed.

Having 2x 6kW Power-Supplies, then you should run your chassis in Redundancy-Mode and go with your proposed setup.

for combined-mode use:

cat6k(config)# power redundancy-mode combined

for redundancy-mode use:

cat6k(config)# power redundancy-mode redundant

verify with:

cat6k# show power

system power redundancy mode = combined

...

Hope this helps!

regards,

Your setup for the power feed to the two power supply to the 6500 is similar.

Instead of having two UPS, we have power supply 1 going to the main power and power supply 2 going to a UPS.
