HP Blade Chassis to Cisco 4500X switch

HP Blade Chassis to Cisco 4500X switch

Matthew need some help:




I need to get in writing that the Cisco WS-C4500x-32sfp+ can connect to the HP C7000 Blade Chassis using the HP DCA cables.  I could find it referenced on  Cisco site confirming the 3 and 5 meter options for the Nexus 5000 and Nexus 2000 here:


However I am not having as much luck with the newer 4500X.  I did find a reference to the approved Cisco modules here,  But in speaking with our engineers, when using these with the HP Chassis, there is nothing but issues.  Whereas using the DCA cables, everything works perfectly.  The customer is asking for this in writing that both companies support this configuration. 


Can you help me get this information confirmed? 




Info from Dan:




Top of Page 28

This spells out the Cisco 1M, 3M and 5M DACs are supported on the 4500X-32SFP+


Then on the HP Side, since you didn’t specify which Ethernet module they were using, I assumed Virtual Connect. (The “c7000” itself has no 10Gb ports)

The Flex-10, FlexFabric and Flex-10/10D all mention support for:

HP C-Series SFP+ to SFP+ Copper 3.0m Direct Attach Cable


HP C-Series SFP+ to SFP+ Copper 5.0m Direct Attach Cable




Then this doc:

has a note that reads:

1: Equivalent to Cisco 3 m 10G SFP+CopperTwinax cable (PN SFP-H10GB-CU3M).

2: Equivalent to Cisco 5 m 10G SFP+Copper Twinax cable (PN SFP-H10GB-CU5M).

Which shows the 3m and 5m C-Series DACs are HP branded versions of the same DACs on the 4500-X Supported list.



Lastly, I put this together a few weeks ago using data provided by some of the really smart guys on the VC team.

It says Nexus, but again, the first link above says the same 3m and 5m cable are supported on the Cat 4500-X.


Cisco DACs that work with both Nexus 5K (and 10GB FEX 2K) and Virtual Connect (Flex-10, FlexFabric, Flex-10/10D)

1 = Cisco has revised their internal Part Number but not their Sales Part number.  Newer versions of these cables may show Uncertified but WILL pass traffic.

See Advisory:

2 = Page 5 under Enhancements

3 = Included in Cisco Support Matrix:

               So Customer should feel safe ordering these cables from HP without fear that Cisco will not support them.
